I con't really mind the color accuracy. My problem was the unifromity, you can visually see the difference between blacks on one part of the screen and on another part. The white point is also off. Both of those things were deal breakers for me.
Back light bleed is the most common complaint with QNIX (and related) since that has to do with the manufacturing quality of the metal frame the panel is in, then case quality. Colors, contrast ratio, input lag, refresh rate, and quality of the panel are not. Note that this is not the common Qnix 2710, but a different and far less popular version.
In general, it is an unbeatable quality monitor for ~$310 shipped. And shipping takes 1-2 days from Korea (literally).
It's unfortunate someone sent them a True10 version of this as it is not the same.
This is just another pretty bad monitor from QNIX. I don't see why people get it when the are much better monitors on the market. /Marco from http://www.consumertop.com/best-monitor-guide/
I am troubled by the fact that the Dell U2713Hm, samsung were left out of most benchmarks results which would compared better than having the dell 32" led in the tests?
Its still readily available, and it would have have been a better comparison since it matches same resolution and screen size.
They don't all test out so poorly. Of course if you really want a quality display for production work, pay the price, this is never going to work for you.
As I always say, fit your hardware choice to your purpose; not everything will work for your tastes or needs. :)
sorry, but this is just poorly written. it took me until the bottom of the first page to realize this wasn't a 4k screen, and sentences like this just baffle me:
"... and utilized the same panel as more expensive offerings, though often with a lower grade panel."
I too was confused about the resolution of the monitor. The first line of the article talked about "QuadHD displays from South Korea" which made me think that's what I was going to be reading about.
Your quoted line about panels caught me off guard too, but after carefully re-reading it about four times I figured out what the author meant.
HD refers to 1280x720 so it logically follows that QHD refers to 2560x1440. Look at some laptop spec sheets, they all claim HD for 1366x768 and Full HD for 1920x1080. This review is not confusing in any way, it just sounds like you guys weren't very familiar with the terminology (which is admittedly kind of confusing).
The terminology isn't confusing. It's stupid, and it always has been. The *GA line isn't any better(it's actually far worse, for various reasons).
Specify resolution with a perfectly good X by Y spec, or don't bother at all. Leave the cute nicknames on the mass-marketing bullet lists where they belong.
The confusion has come in when people have begin referring to 1920x1080 as "HD". By that definition, "QuadHD" then implies 4x1080p or 4K, which is incorrect. QuadHD has always been 2560x1440. So the confusion doesn't come from how the article is written - it comes from the incorrect definition of "HD" that has perpetuated over the last few years as new confusing acronyms are coined for higher-resolution displays.
The confusion comes in when people refer to the vertical resolution for years and years (480p, 720p, 1080p) and then switch to using the horizontal resolution (2K, 4K), especially considering those monikers are off by several hunder to a thousand pixels.
If everyone just keeps using the vertical resolution, then nobody gets confused. 480p 720p 1080p 1440p 2160p
Nice, neat, simple. Changing definitions in the middle is what's causing all the issues.
Panel grading refers to manufacturing defects, these ebay panels are usually B grade on a scale of A+,A,A-,B,C. Also WQHD is 1440p as the keywords, article, charts, and text state...
"At a time when a $700 monitor was considered cheap in the United States, these were available on Ebay for around $300 and utilized the same panel as more expensive offerings, though often with a lower grade panel."
What's confusing about that? Several years ago, the cheapest QHD panels in the US cost $700+, but you could find a Korean brand display off of eBay for $300. They used the same panel (as there are only a few companies that actually manufacture LCD panels -- AUO, Chi Mei, LG, and Samsung are the biggest), but panels are also graded on quality as well. So the same panel out of LG will have a set resolution and generally similar characteristics, but if it's not very uniform or has a few dead pixels it would receive a lower grade. The shortened form of this explanation given in the article is due to the fact that this is all generally common knowledge, so we don't tend to go into a lengthy explanation every time we talk about a display.
And as to the 4K vs. QHD aspect... sorry if you're not up to speed on acronyms, but QHD has always been 2560x1440. QHD+ is sometimes called 3K (but there are multiple "3K" resolutions) whereas 4K is generally referred to as UHD (and again, there are multiple "4K" resolutions). Here's a link covering nearly every commonly used resolution: http://en.wikipedia.org/wiki/Graphics_display_reso...
I hardly believe insulting the readers is the best way for one of the authors to express himself. It's unprofessional and goes against everything I have read or heard from Anand when he refers to the readers.
Yes it's true that not everyone who reads this site is familiar with all of the terminology, and in this case the terminology even stumped Google because the first thing I did when I came across QHD was a search and the first result was the 2160p article on Wikipedia. Perhaps referring to the vertical pixels early on would have been helpful in this case, because a number (1440) is a lot harder to confuse than letters when describing the number of pixels on a monitor.
"Same panel" and "lower grade panel" appear mutually exclusive to a casual reader or to a literal one (with the latter heavily represented here, I bet.). A lower graded panel of the same model family is still not the "same panel" anywhere outside of a used car lot.
At best this was a sloppily constructed sentence and more realistically it was unnecessarily confusing to a lot of readers.
2560x1440 panels are called QHD, while 4K are called UHD. By grade, the author means that they are not rated A or A+. A panel with a defect, like a dead pixel or a tiny scratch is rated below this, and OEMS like Samsung or Apple won't accept them. Local companies buy them and manufacture monitors like this.
quad hd means 4 times as many pixels on the screen as 720p ie 1280x720 (921600 pixels) 2560x1440 (3686400 pixels) is quad hd. 4k is a stupid misleading term.
I have an X-Star DP2710 and my results are quite a bit different from this review.
-My model is the DVI-only version which I got because they supposedly have lower input lag. I don't have a way of testing the input lag, but I have not perceptually noticed any, coming from a 120 hz VA LCD previously. -My model has no OSD, only brightness up/down buttons. -My model overclocks to 120hz, however overclocking severely affects the gamma and contrast. -Similar to the article, my panel has bad uniformity issues and only average contrast. -My model has nearly perfect gamma calibration right out of the box. This monitor has the best default calibration settings I've ever seen. I don't have a color calibrator but this guy's review indicates similarly that these panels have excellent default color calibration: http://www.youtube.com/watch?v=0EMmNmvFcAA
I wonder if I just got lucky and got a good batch, or did they change their product since last year or what.
These are low grade panels. There's probably a lot more variation between individual screens than with a Dell or Apple branded monitor; never mind professional level NEC or Eizo monitors.
Please use metric system for measurements or at least also list them. After all anandtech deals with technical gadgets and not with flour, sugar and wood.
In my case, which I live in Thailand where the standard measurements are in metric system, the screen size in general terms are in imperial. However when reporting the exact dimension of the display, the measurements are in metric. (for example Sony KDL-70W850B is 70" LCD TV, the dimension is 1,586x970x370mm).
I guess this is the case in many countries as well.
There are brochures that even has the diagonal screen size in metric system written in parenthesis after the imperial one, but no one pays attention to it.
Also note according to the overclock.net forums, only the DVI-only panels can truly overclock refresh rate. The multi-input panels can force higher refresh rate, but they just simply drop the extra frames.
Thanks for pointing this out. I tested this today and it is the case, so I updated the review. Screenshots are included as well. I'll make sure to run that test in the future to avoid this mistake.
Bought a Yamakasi 27" WQHD for ~310 USD. It's great .. except it has a dark speck just to the left of center between the panel and glass. If one concentrates on this imperfection it would drive anyone nuts. I just focus on the 310 USD and everything is fine, every once and awhile though......
This model of the Qnix doesn't overclock properly. Overclocks of monitors need to be validated to verify that it doesn't skip frames when overclocked.
This particular model will not show every frame of an overclock - for example, a 90hz overclock will actually result in the monitor only showing 2 out of every 3 frames. Try using the UFO test: Frame Skipping Checker to ensure that your monitor does properly overclock.
These monitors are not "best thing to happen to the computer monitor market". This is a cheap monitor and it shows. Full of gimmicks too (integrated speakers, downscaling of 4k). I don't know why it's appearing on Anandtech. The front page is also unclear and doesn't state the panel type as far as I can see.
Because if these displays hadn't come out, we'd probably still be paying $1,000 and up for a quality 27" panel in the US. Now you can get a nice display for $450 and a really nice one for $600-650. Even if the quality of the $300 models isn't great, it has still put pressure on the pricing of the higher-end models and made them more affordable.
Not sure about that. I think if you produce a high quality 27" display your main competition is other high quality 27" displays, and after than high quality 23 or 24 or 30" displays.
If it were a good value cheap product I would understand. But there are much better ways to make a cheap product. Take out the frills, stick with a single displayport, skimp on casing and stand. Putting a lot of cheap parts together and adding some extra cheap parts for the hell of it is not the way to make a good value product.
First of all - these aren't the monitors people want from Korea, the ones you buy are the QNix QX2710 and the X-Star DP2710 (or the Catleaps if you want to go back in time to when this started).
Secondly, for $300 you get a fairly good monitor that has a 1440p resolution and is overclockable anywhere from 96 to 120 Hz (and beyond if you're really lucky). I'm not sure if the reviewer was aware, but the monitor he selected probably actually isn't overclocked to 110 FPS. This model simply drops the frames, you have to test for frame skipping, not just what it "says" it's overclocked to. Multi-input models are widely known to do this while the single-input models actually do overclock.
The input lag the reviewer reported is also due to the multiple inputs. The single input version actually has a 2-3ms input lag, which is very good. So that downside wasn't a big surprise to many readers who have researched these panels in the past.
Now I won't deny that these (I'm referring to the desired models, not the reviewed model) monitors do have a "luck of the draw" kind of statistic to them, but even in the worst of cases purchasing a QNix or X-Star monitor gives you access to a quality panel (Samsung PLS - the one the reviewed is AHVA) that isn't available until you start spending hundres more - and those stay at 60 Hz.
For the money you spend you're getting great value, do you know of a comparable monitor that can produce >=96 Hz at 1440p on a Samsung PLS panel for ~$300? I'd love to know if you do, because I'm in the market for a new one and was going to purchase a second X-Star DP2710 because I love the one I have.
I'm disappointed in Anandtech for publishing this, they really dropped the ball and obviously didn't research much into what they were reviewing before posting this. I've been dying to see a review of the Samsung PLS model QNix and X-Stars against more expensive models, but what we got ignored a lot of community research that has been happening over the many years these inexpensive monitors have been available.
As an addendum, the fact the "wrong" model was reviewed isn't bad in and of itself. The fact the misconception of the negative aspects of this multi-input model is spreading to "all Korean models" because of an utter lack of mentioning the other variants is unacceptable.
I do applaud the reviewer for at least killing the misconception of this model being actually overclockable through his edit he just posted; that said, the fact the review mentions the "QNix" as not overclockable without mentioning the single-input variants which ARE is quite disheartening.
I wonder if the other reviewers on this site have an equal lack of understanding for the products they're reviewing as Chris does for monitors.
I totally agree on all points. This seemed thoughtlessly put together and was way below the level of thoroughness I've become accustomed to on Anandtech.
>First of all - these aren't the monitors people want from Korea, the ones you buy are the QNix QX2710 and the X-Star DP2710 (or the Catleaps if you want to go back in time to when this started).
Yup. This is not the 'QNIX' people are talking about when they talk about the great value in Korean monitors. Anyone following the recommendations knows to stay away from this model.
As it stands, the only way to get a 1400p IPS/PLS display at greater than 90 (and sometimes all the way to 120) is STILL the Korean QX2710 or DP2710 which are both still shipping for less than 300 dollars. It's not just a bargain it's literally the only way to find a display that meets those requirements.
To make matters even more confusing, the QNIX QX2710 exists in both multi-input and DL-DVI-only variants. Only the latter variant OC's properly without skipping frames
Appreciate the review, but this model has been known since shortly after release in the OCN Qnix / X-Star PLS club to be the worst of the Qnix family, best avoided.
The monitor has high input lag (2 frames), low contrast ratio (700:1), doesn't overclock (skips frames), and uses PWM backlight control. I knew these even before I read your review. Your review confirms that this is a Korean monitor best avoided.
On the other hand, the Qnix QX2710 Evolution II single-input and multi-input models have none of these issues. The single-input DVI dual-link model has no input lag (~2-3ms?), higher contrast ratio (900:1 - 1100:1), overclocks to 100Hz+ easily (many get 110-120Hz), and very very few users have ever reported PWM flicker, meaning most likely it either doesn't use PWM at all (save for 2-3 cases on the Internet ~160Hz) or it uses a high frequency not visible to most / all (mine).
The multi-input model has 1 frame of lag, not 2, doesn't OC, and one measurement put it at 900:1 (NCX - had another 1100:1 single-input glow-free PWM-free Matte).
These are my results with my Qnix QX2710 EvoII single-input DVI-DL (out-of-the-box; arrived August 1, 2013; measured recently late March,2014) - using an i1 Display Pro, HCFR for measurements, ArgyllCMS + dispcalGUI for calibration and profiling:
Gamma @ 2.04, Contrast Ratio @ 890:1, average DE @ 1.9
My monitor is one of those with a slight yellowish tint out-of-the-box. Imagine how the samples that don't have this tint would measure (NCX - ~perfect white, little difference with calibration).
Calibration & Profiling results:
Profiling results (ArgyllCMS + dispcalGUI): http://i.imgur.com/tkFrJ7n.png This shows a 99.7% sRGB gamut coverage and a 75.1% Adobe RGB gamut coverage.
This is with my monitor having slight yellow bleed (because of the case causing pressure) starting from the bottom middle stretching towards the right side of the screen, visible only in the darkest of scenes with the lights off.
Overclocks to 110Hz with some tightened timings, reaches 116Hz or so before it starts artifacting lightly (120Hz has ~2 green lines constantly on the screen). All on the stock cable and same GPU DVI-DL port.
So if someone were looking at a $500 or less monitor with the best quality that price could afford which would be advised? Would it be one of the Korean models you just mentioned or is their a normal reputable vendor like Asus or ViewSonic that have a good quality monitor around this price? I'm looking for something as close to the quality of the Apple Thunderbolt quality/panel as possible.
I personally acquired an X-Star DP2710 LED (identical to the QX2710 that yasamoka has). I would say the ONLY drawbacks are the el-cheapo stand, and only a DL-DVI input.
But really? Compares to the positives? My monitor has NO dead pixels, overclocks to 120Hz with no dropped frames or random anomalies, and has 1000:1 contrast ratio. Do you really need 2 inputs? No son, you need 2 monitors!
I paid $300USD + $50 in taxes and import fees on delivery = $350.
Do not let Anandtech's review sway you as they reviewed a totally different monitor. For the resolution, colour quality, and price it's easily the best thing under $500.
I created an account to reply to this. I just purchased a single-input QX27 Evo II via an Amazon reseller. (Had a small defect in corner of screen, so in transit for replacement; whole process was very smooth, reseller very cooperative, in case this is a cause of worry for anyone.)
The image quality is imperfect. There is some light bleed (this is common, but varies from monitor to monitor) which leads to problems with brightness uniformity. Contrast is good, but I still have to settle for some crushed whites or some crushed blacks. Overall, however, the image quality makes me very happy. It is miles ahead of my old TN screen. Just, it's not appropriate for graphics professionals.
As far as gaming, my monitor overclocked to 120hz without graphical glitches. Again, this varies, but 96hz seems like a very reasonable and easily achieved overclock. Verified via testUFO, btw. Reports are of 1ms input lag, which I find hard to believe, but I will say that I (no professional gamer) noticed no input lag. However, 120hz on a monitor like this isn't 120hz on a benq or asus with a strobe, because of persistence. Much as with image quality, gaming performance is very good, but not appropriate for a gaming professional.
And the price is right. Amazon resellers have these available for $350. These resellers aim to please, because they're getting good money, but have to keep Amazon happy to stay listed, and Amazon is happy if you're happy.
So it's not a great monitor towards any particular purpose, and it's not a great monitor at any price point, but for its cost, I am really happy with the QNIX, and think it's a wonderful jack-of-all-trades.
The confusion has come in when people have begin referring to 1920x1080 as "HD". By that definition, "QuadHD" then implies 4x1080p or 4K, which is incorrect. QuadHD has always been 2560x1440. So the confusion doesn't come from how the article is written - it comes from the incorrect definition of "HD" that has perpetuated over the last few years as new confusing acronyms are coined for higher-resolution displays. http://s6x.it/l521
I still appreciate the review. Between the review and the comments I have a much better understanding of these low cost monitors. I'm still rocking a 24 inch Soyo Topaz, which I love, but will be looking at these when mine dies.
If you keep an eye out on craigslist you can find really good deals and people will usually negotiate. I got a dell u3014 2560x1600 and I only paid 625 including the gas to drive and get it. The outer bezel had some scuff marks but the panel performed flawlessly. It was still perfectly calibrated, almost perfect uniformity and it ran very cool to the touch compared to other monitors.
Yes 625 isn't as cheap as basically close to 400 after all is said and done getting a korean monitor. But this is 16:10 and 30" with more pixels. When you are only saving that much though is it worth the risk of dead pixels and crappy build quality and questionable longevity. Keep an eye on your local craigslist's for high end monitors. This is where you'll find the best deal.
I'll be sticking with the dell u3014 for a long time as the only upgrade i can look forward to is one of the 32" 4k UHD monitors and they are way overpriced for quality ones.
That was a good deal. At the time I was looking at 1440p monitors, 30" 1600p ones were still going for 750 to 900€. I got my Samsung one for 540€ because of a discount. And besides the refresh rate, it is a super great panel with the right amount of anti glare. I'm looking forward to a 4k model in a year or so, when 60Hz and compatibility of good. :)
There's no way to say at all how it would perform. The firmware is different, and as we've found before (look at the two LG 29EA93 reviews), a firmware update can make a monitor completely different. So the panel might be the same, but that's just one part of a display.
I have a QNIX QX2710 (normal one, with dual DVI only connection) and it dosent skip any frames at 120Mhz, I also did the test myself. I totally recommend it for gaming. I think AnandTech should not be cheap and spend 300 bucks and review that one. The one´s with multiple connections dont OC well.
I am extremely disappointed due to this article. First of all the korean monitors (eBay) are not meant for professional usage. They're meant for gamers who want a reliable 2560x1440 monitor.
Second of all, you don't purchase the multi input version for gaming. They're horrible at overclocking and have more input lag. The version that only comes with one input (dual DVI) is what should be purchased. I paid $300 for my Xstar (same panel) with single dual DVI back in October. I had zero dead pixels, minimal lightbleeding and am able to OC it to 96 Hz without frame skips.
I love Anandtech because usually when i come here to see reviews I see good reviews from people who do their research. I made an account just so that I could post this comment.
im a bit confused with AHVA panel. Is it something new? Is it better then IPS/PLS?
I wouldn't mind to pay 50xtra for proper stand with all tilt/shift options something like Dell has and another 50xtra for factory calibrated screen. Pity none of these cheapos have this options. If I'm mistaken plz post a link.
I think the reason that this screen isn't capable of overclocking is because it has lots of processing in order to use DP and the menu system. I own the Qnix QX2710 with Dual Link DVI input only, and it overclocks to 120hz without a hitch. Used the same test as author to verify results. However, I agree about the colors looking washed out compared to my Dell Ultrasharp.
You picked one of the versions that does not overclock. The single input models (DVI-D only) CAN overclock easily. Is there anyway you can update the article concerning overclocking using one of these models? Any of these models that have more than one input will not overclock.
Not to mention has inferior contrast, colors and input lag. The "regular" QX2710 and DP2710LED are some of the best monitors on the market, period. They offer a combo of features that NO other monitors offer at ANY price point: amazing colors Good contrast for IPS type display zero input lag overclockable great view angle non-pwm dimming
I purchased a Qnix monitor a couple of years ago now. It was $285 delivered. And it has been great. I guess I won the panel lottery or something as there are no dead pixels, minimal backlight bleed and the color is uniform across the screen. It just has the Dual DVI input, which I don't mind but others may find bothersome.
There is some element of risk buying these I suppose. With Apple or Dell, you know you will get prompt service or replacement if you're unhappy. But saving $700 made it a gamble I was willing to make.
I was willing to pay for a good monitor around $700 but I found that Qnix DVI-D is equal or better than those monitors. Was really looking forward to purchasing this model. Pls suggest a good one for photo editing.
They are amazing. I have them OCed at 96hz which makes everything smoother than 60hz.
Only one of the panels can go to 120Hz without problems. The other one will just give weird red lines so the sweetspot was a 96hz for me. Games running at 96FPS or 120 FPS is hard for me to tell that much of a difference. I love these badboys.
The resolution is amazing and i have no problems with colors. I am not doing photography or webdesign. I am playing video games and they look no different than my old 1080p panel.
You have reviewed the WRONG QNIX. The popular one is the over-clockable QNIX QX2710 Evolution II PLS LED Display with a single DVI-D interface that cost approx $300 from South Korea.
The reason you were unable to overclock without dropping frames is because you have the wrong version of this monitor. Only the base models (single dual-dvi input) of the QNIX QX2710 and XSTAR 2710 and Yamasaki Catleap 2B that are able to overclock. None of the multi-input models are able to overclock, the only reason the base models are able to overclock is because of the bypass board (and lack of a scaler). As a side effect, you cannot hook up console gaming systems because they will not be able to output a supported resolution due to the lack of a scaler on the monitor.
I have seen countless posts on this topic, seen countless screenshots of the proof they don't frame skip and I personally own the XSTAR version (same monitor, different reseller) and have it overclocked to 110 without any frame dropping. I was able to get to 120hz but I start getting artifacts in some games (Skyrim) at that framerate and so I chose to drop down for ease of use.

Wow I always assumed these cheapo panels were garbage, but 500:1 contrast and a 50% uniformity? I'll take a cheap 1080p *VA over this any day.peterfares - Friday, April 11, 2014 - link
If color accuracy is most important to you then that's probably good idea.I on the other hand don't need color accuracy for what I use my computer for. For me, resolution is king.

Back light bleed is the most common complaint with QNIX (and related) since that has to do with the manufacturing quality of the metal frame the panel is in, then case quality. Colors, contrast ratio, input lag, refresh rate, and quality of the panel are not. Note that this is not the common Qnix 2710, but a different and far less popular version.In general, it is an unbeatable quality monitor for ~$310 shipped. And shipping takes 1-2 days from Korea (literally).
It's unfortunate someone sent them a True10 version of this as it is not the same.

This is just another pretty bad monitor from QNIX. I don't see why people get it when the are much better monitors on the market. /Marco from http://www.consumertop.com/best-monitor-guide/edlee - Friday, April 11, 2014 - link

They don't all test out so poorly. Of course if you really want a quality display for production work, pay the price, this is never going to work for you.As I always say, fit your hardware choice to your purpose; not everything will work for your tastes or needs. :)

Yes. The line under the heading referring to 2560x1440 confused me as well...pattycake0147 - Friday, April 11, 2014 - link
I too was confused about the resolution of the monitor. The first line of the article talked about "QuadHD displays from South Korea" which made me think that's what I was going to be reading about.Your quoted line about panels caught me off guard too, but after carefully re-reading it about four times I figured out what the author meant.

HD refers to 1280x720 so it logically follows that QHD refers to 2560x1440. Look at some laptop spec sheets, they all claim HD for 1366x768 and Full HD for 1920x1080. This review is not confusing in any way, it just sounds like you guys weren't very familiar with the terminology (which is admittedly kind of confusing).LordOfTheBoired - Sunday, April 13, 2014 - link
The terminology isn't confusing. It's stupid, and it always has been. The *GA line isn't any better(it's actually far worse, for various reasons).Specify resolution with a perfectly good X by Y spec, or don't bother at all. Leave the cute nicknames on the mass-marketing bullet lists where they belong.
WithoutWeakness - Friday, April 11, 2014 - link
HD = 1280x720FullHD (FHD) = 1920x1080
QuadHD (QHD) = 2560x1440
UltraHD (UHD, 4K) = 3840x2160
The confusion has come in when people have begin referring to 1920x1080 as "HD". By that definition, "QuadHD" then implies 4x1080p or 4K, which is incorrect. QuadHD has always been 2560x1440. So the confusion doesn't come from how the article is written - it comes from the incorrect definition of "HD" that has perpetuated over the last few years as new confusing acronyms are coined for higher-resolution displays.

The confusion comes in when people refer to the vertical resolution for years and years (480p, 720p, 1080p) and then switch to using the horizontal resolution (2K, 4K), especially considering those monikers are off by several hunder to a thousand pixels.If everyone just keeps using the vertical resolution, then nobody gets confused.
480p
720p
1080p
1440p
2160p
Nice, neat, simple. Changing definitions in the middle is what's causing all the issues.

Panel grading refers to manufacturing defects, these ebay panels are usually B grade on a scale of A+,A,A-,B,C. Also WQHD is 1440p as the keywords, article, charts, and text state...blackoctagon - Thursday, May 1, 2014 - link
They're not only sold on eBay and the panel grade is actually A-JarredWalton - Saturday, April 12, 2014 - link
"At a time when a $700 monitor was considered cheap in the United States, these were available on Ebay for around $300 and utilized the same panel as more expensive offerings, though often with a lower grade panel."What's confusing about that? Several years ago, the cheapest QHD panels in the US cost $700+, but you could find a Korean brand display off of eBay for $300. They used the same panel (as there are only a few companies that actually manufacture LCD panels -- AUO, Chi Mei, LG, and Samsung are the biggest), but panels are also graded on quality as well. So the same panel out of LG will have a set resolution and generally similar characteristics, but if it's not very uniform or has a few dead pixels it would receive a lower grade. The shortened form of this explanation given in the article is due to the fact that this is all generally common knowledge, so we don't tend to go into a lengthy explanation every time we talk about a display.
And as to the 4K vs. QHD aspect... sorry if you're not up to speed on acronyms, but QHD has always been 2560x1440. QHD+ is sometimes called 3K (but there are multiple "3K" resolutions) whereas 4K is generally referred to as UHD (and again, there are multiple "4K" resolutions). Here's a link covering nearly every commonly used resolution: http://en.wikipedia.org/wiki/Graphics_display_reso...

I hardly believe insulting the readers is the best way for one of the authors to express himself. It's unprofessional and goes against everything I have read or heard from Anand when he refers to the readers.Yes it's true that not everyone who reads this site is familiar with all of the terminology, and in this case the terminology even stumped Google because the first thing I did when I came across QHD was a search and the first result was the 2160p article on Wikipedia. Perhaps referring to the vertical pixels early on would have been helpful in this case, because a number (1440) is a lot harder to confuse than letters when describing the number of pixels on a monitor.

"Same panel" and "lower grade panel" appear mutually exclusive to a casual reader or to a literal one (with the latter heavily represented here, I bet.). A lower graded panel of the same model family is still not the "same panel" anywhere outside of a used car lot.At best this was a sloppily constructed sentence and more realistically it was unnecessarily confusing to a lot of readers.
vgu - Tuesday, April 15, 2014 - link
2560x1440 panels are called QHD, while 4K are called UHD.By grade, the author means that they are not rated A or A+.
A panel with a defect, like a dead pixel or a tiny scratch is rated below this, and OEMS like Samsung or Apple won't accept them. Local companies buy them and manufacture monitors like this.
skuul88 - Thursday, January 15, 2015 - link
quad hd means 4 times as many pixels on the screen as 720p ie 1280x720 (921600 pixels) 2560x1440 (3686400 pixels) is quad hd. 4k is a stupid misleading term.jaydee - Friday, April 11, 2014 - link

I have an X-Star DP2710 and my results are quite a bit different from this review.-My model is the DVI-only version which I got because they supposedly have lower input lag. I don't have a way of testing the input lag, but I have not perceptually noticed any, coming from a 120 hz VA LCD previously.
-My model has no OSD, only brightness up/down buttons.
-My model overclocks to 120hz, however overclocking severely affects the gamma and contrast.
-Similar to the article, my panel has bad uniformity issues and only average contrast.
-My model has nearly perfect gamma calibration right out of the box. This monitor has the best default calibration settings I've ever seen. I don't have a color calibrator but this guy's review indicates similarly that these panels have excellent default color calibration: http://www.youtube.com/watch?v=0EMmNmvFcAA

It's funny... Let's use the metric system to talk about a 27" (or should we say 68.58cm?) panel.mr_tawan - Friday, April 11, 2014 - link
In my case, which I live in Thailand where the standard measurements are in metric system, the screen size in general terms are in imperial. However when reporting the exact dimension of the display, the measurements are in metric. (for example Sony KDL-70W850B is 70" LCD TV, the dimension is 1,586x970x370mm).I guess this is the case in many countries as well.
There are brochures that even has the diagonal screen size in metric system written in parenthesis after the imperial one, but no one pays attention to it.

This model of the Qnix doesn't overclock properly. Overclocks of monitors need to be validated to verify that it doesn't skip frames when overclocked.This particular model will not show every frame of an overclock - for example, a 90hz overclock will actually result in the monitor only showing 2 out of every 3 frames. Try using the UFO test: Frame Skipping Checker to ensure that your monitor does properly overclock.

These monitors are not "best thing to happen to the computer monitor market".This is a cheap monitor and it shows.
Full of gimmicks too (integrated speakers, downscaling of 4k).

It's here because for several years people have been requesting that some of the cheap 27" panels be reviewed for comparison with higher end models.peterfares - Friday, April 11, 2014 - link
Because the resolutions are awesome. We've been stuck at 1920x1080 for YEARS. It's about time we moved up to something better.cheinonen - Friday, April 11, 2014 - link
Because if these displays hadn't come out, we'd probably still be paying $1,000 and up for a quality 27" panel in the US. Now you can get a nice display for $450 and a really nice one for $600-650. Even if the quality of the $300 models isn't great, it has still put pressure on the pricing of the higher-end models and made them more affordable.CSMR - Friday, April 11, 2014 - link
Not sure about that. I think if you produce a high quality 27" display your main competition is other high quality 27" displays, and after than high quality 23 or 24 or 30" displays.If it were a good value cheap product I would understand. But there are much better ways to make a cheap product. Take out the frills, stick with a single displayport, skimp on casing and stand. Putting a lot of cheap parts together and adding some extra cheap parts for the hell of it is not the way to make a good value product.
Hxx - Friday, April 11, 2014 - link
Chris you made my day by reviewing this panel. Thanks for sharing with the world how awful these korean monitors actually are.JoeArchitect - Friday, April 11, 2014 - link
Don't jump to conclusions now.First of all - these aren't the monitors people want from Korea, the ones you buy are the QNix QX2710 and the X-Star DP2710 (or the Catleaps if you want to go back in time to when this started).
Secondly, for $300 you get a fairly good monitor that has a 1440p resolution and is overclockable anywhere from 96 to 120 Hz (and beyond if you're really lucky). I'm not sure if the reviewer was aware, but the monitor he selected probably actually isn't overclocked to 110 FPS. This model simply drops the frames, you have to test for frame skipping, not just what it "says" it's overclocked to. Multi-input models are widely known to do this while the single-input models actually do overclock.
The input lag the reviewer reported is also due to the multiple inputs. The single input version actually has a 2-3ms input lag, which is very good. So that downside wasn't a big surprise to many readers who have researched these panels in the past.
Now I won't deny that these (I'm referring to the desired models, not the reviewed model) monitors do have a "luck of the draw" kind of statistic to them, but even in the worst of cases purchasing a QNix or X-Star monitor gives you access to a quality panel (Samsung PLS - the one the reviewed is AHVA) that isn't available until you start spending hundres more - and those stay at 60 Hz.
For the money you spend you're getting great value, do you know of a comparable monitor that can produce >=96 Hz at 1440p on a Samsung PLS panel for ~$300? I'd love to know if you do, because I'm in the market for a new one and was going to purchase a second X-Star DP2710 because I love the one I have.
I'm disappointed in Anandtech for publishing this, they really dropped the ball and obviously didn't research much into what they were reviewing before posting this. I've been dying to see a review of the Samsung PLS model QNix and X-Stars against more expensive models, but what we got ignored a lot of community research that has been happening over the many years these inexpensive monitors have been available.
JoeArchitect - Friday, April 11, 2014 - link
As an addendum, the fact the "wrong" model was reviewed isn't bad in and of itself. The fact the misconception of the negative aspects of this multi-input model is spreading to "all Korean models" because of an utter lack of mentioning the other variants is unacceptable.I do applaud the reviewer for at least killing the misconception of this model being actually overclockable through his edit he just posted; that said, the fact the review mentions the "QNix" as not overclockable without mentioning the single-input variants which ARE is quite disheartening.
I wonder if the other reviewers on this site have an equal lack of understanding for the products they're reviewing as Chris does for monitors.

>First of all - these aren't the monitors people want from Korea, the ones you buy are the QNix QX2710 and the X-Star DP2710 (or the Catleaps if you want to go back in time to when this started).Yup. This is not the 'QNIX' people are talking about when they talk about the great value in Korean monitors. Anyone following the recommendations knows to stay away from this model.
As it stands, the only way to get a 1400p IPS/PLS display at greater than 90 (and sometimes all the way to 120) is STILL the Korean QX2710 or DP2710 which are both still shipping for less than 300 dollars. It's not just a bargain it's literally the only way to find a display that meets those requirements.

To make matters even more confusing, the QNIX QX2710 exists in both multi-input and DL-DVI-only variants. Only the latter variant OC's properly without skipping framesyasamoka - Friday, April 11, 2014 - link
Appreciate the review, but this model has been known since shortly after release in the OCN Qnix / X-Star PLS club to be the worst of the Qnix family, best avoided.The monitor has high input lag (2 frames), low contrast ratio (700:1), doesn't overclock (skips frames), and uses PWM backlight control. I knew these even before I read your review. Your review confirms that this is a Korean monitor best avoided.
On the other hand, the Qnix QX2710 Evolution II single-input and multi-input models have none of these issues. The single-input DVI dual-link model has no input lag (~2-3ms?), higher contrast ratio (900:1 - 1100:1), overclocks to 100Hz+ easily (many get 110-120Hz), and very very few users have ever reported PWM flicker, meaning most likely it either doesn't use PWM at all (save for 2-3 cases on the Internet ~160Hz) or it uses a high frequency not visible to most / all (mine).
The multi-input model has 1 frame of lag, not 2, doesn't OC, and one measurement put it at 900:1 (NCX - had another 1100:1 single-input glow-free PWM-free Matte).

So if someone were looking at a $500 or less monitor with the best quality that price could afford which would be advised? Would it be one of the Korean models you just mentioned or is their a normal reputable vendor like Asus or ViewSonic that have a good quality monitor around this price? I'm looking for something as close to the quality of the Apple Thunderbolt quality/panel as possible.iamkyle - Thursday, April 17, 2014 - link
I personally acquired an X-Star DP2710 LED (identical to the QX2710 that yasamoka has). I would say the ONLY drawbacks are the el-cheapo stand, and only a DL-DVI input.But really? Compares to the positives? My monitor has NO dead pixels, overclocks to 120Hz with no dropped frames or random anomalies, and has 1000:1 contrast ratio. Do you really need 2 inputs? No son, you need 2 monitors!
I paid $300USD + $50 in taxes and import fees on delivery = $350.
Do not let Anandtech's review sway you as they reviewed a totally different monitor. For the resolution, colour quality, and price it's easily the best thing under $500.
vasiln - Wednesday, April 23, 2014 - link
I created an account to reply to this. I just purchased a single-input QX27 Evo II via an Amazon reseller. (Had a small defect in corner of screen, so in transit for replacement; whole process was very smooth, reseller very cooperative, in case this is a cause of worry for anyone.)The image quality is imperfect. There is some light bleed (this is common, but varies from monitor to monitor) which leads to problems with brightness uniformity. Contrast is good, but I still have to settle for some crushed whites or some crushed blacks. Overall, however, the image quality makes me very happy. It is miles ahead of my old TN screen. Just, it's not appropriate for graphics professionals.
As far as gaming, my monitor overclocked to 120hz without graphical glitches. Again, this varies, but 96hz seems like a very reasonable and easily achieved overclock. Verified via testUFO, btw. Reports are of 1ms input lag, which I find hard to believe, but I will say that I (no professional gamer) noticed no input lag. However, 120hz on a monitor like this isn't 120hz on a benq or asus with a strobe, because of persistence. Much as with image quality, gaming performance is very good, but not appropriate for a gaming professional.
And the price is right. Amazon resellers have these available for $350. These resellers aim to please, because they're getting good money, but have to keep Amazon happy to stay listed, and Amazon is happy if you're happy.
So it's not a great monitor towards any particular purpose, and it's not a great monitor at any price point, but for its cost, I am really happy with the QNIX, and think it's a wonderful jack-of-all-trades.

If you keep an eye out on craigslist you can find really good deals and people will usually negotiate. I got a dell u3014 2560x1600 and I only paid 625 including the gas to drive and get it. The outer bezel had some scuff marks but the panel performed flawlessly. It was still perfectly calibrated, almost perfect uniformity and it ran very cool to the touch compared to other monitors.Yes 625 isn't as cheap as basically close to 400 after all is said and done getting a korean monitor. But this is 16:10 and 30" with more pixels. When you are only saving that much though is it worth the risk of dead pixels and crappy build quality and questionable longevity. Keep an eye on your local craigslist's for high end monitors. This is where you'll find the best deal.
I'll be sticking with the dell u3014 for a long time as the only upgrade i can look forward to is one of the 32" 4k UHD monitors and they are way overpriced for quality ones.

That was a good deal. At the time I was looking at 1440p monitors, 30" 1600p ones were still going for 750 to 900€. I got my Samsung one for 540€ because of a discount. And besides the refresh rate, it is a super great panel with the right amount of anti glare.

There's no way to say at all how it would perform. The firmware is different, and as we've found before (look at the two LG 29EA93 reviews), a firmware update can make a monitor completely different.

I am extremely disappointed due to this article.First of all the korean monitors (eBay) are not meant for professional usage. They're meant for gamers who want a reliable 2560x1440 monitor.
Second of all, you don't purchase the multi input version for gaming. They're horrible at overclocking and have more input lag. The version that only comes with one input (dual DVI) is what should be purchased. I paid $300 for my Xstar (same panel) with single dual DVI back in October. I had zero dead pixels, minimal lightbleeding and am able to OC it to 96 Hz without frame skips.
I love Anandtech because usually when i come here to see reviews I see good reviews from people who do their research. I made an account just so that I could post this comment.

I think the reason that this screen isn't capable of overclocking is because it has lots of processing in order to use DP and the menu system.I own the Qnix QX2710 with Dual Link DVI input only, and it overclocks to 120hz without a hitch. Used the same test as author to verify results.
However, I agree about the colors looking washed out compared to my Dell Ultrasharp.

I purchased a Qnix monitor a couple of years ago now. It was $285 delivered. And it has been great. I guess I won the panel lottery or something as there are no dead pixels, minimal backlight bleed and the color is uniform across the screen. It just has the Dual DVI input, which I don't mind but others may find bothersome.There is some element of risk buying these I suppose. With Apple or Dell, you know you will get prompt service or replacement if you're unhappy. But saving $700 made it a gamble I was willing to make.

I was willing to pay for a good monitor around $700 but I found that Qnix DVI-D is equal or better than those monitors. Was really looking forward to purchasing this model. Pls suggest a good one for photo editing.cubebomb - Sunday, April 20, 2014 - link
I have two of these i bought 6 months ago.They are amazing. I have them OCed at 96hz which makes everything smoother than 60hz.
Only one of the panels can go to 120Hz without problems. The other one will just give weird red lines so the sweetspot was a 96hz for me. Games running at 96FPS or 120 FPS is hard for me to tell that much of a difference. I love these badboys.
The resolution is amazing and i have no problems with colors. I am not doing photography or webdesign. I am playing video games and they look no different than my old 1080p panel.
I am playing 96fps at 1440p ! amazing

You have reviewed the WRONG QNIX. The popular one is the over-clockable QNIX QX2710 Evolution II PLS LED Display with a single DVI-D interface that cost approx $300 from South Korea.aithos - Friday, July 25, 2014 - link
Clarification of Overclocking on QNIX:The reason you were unable to overclock without dropping frames is because you have the wrong version of this monitor. Only the base models (single dual-dvi input) of the QNIX QX2710 and XSTAR 2710 and Yamasaki Catleap 2B that are able to overclock. None of the multi-input models are able to overclock, the only reason the base models are able to overclock is because of the bypass board (and lack of a scaler). As a side effect, you cannot hook up console gaming systems because they will not be able to output a supported resolution due to the lack of a scaler on the monitor.
I have seen countless posts on this topic, seen countless screenshots of the proof they don't frame skip and I personally own the XSTAR version (same monitor, different reseller) and have it overclocked to 110 without any frame dropping. I was able to get to 120hz but I start getting artifacts in some games (Skyrim) at that framerate and so I chose to drop down for ease of use.

Yes..they know that now. It's been brought up many times over the last several months in this thread.
