It seems just a short while ago, owning a monitor larger than 19" was unheard of, unless you had won the lottery. Yet, 19" is still the main focus right now because of its price. But the price of this 22" model is not too far off the 19" monitors. It can be purchased for as low as $999 USD. This monitor has the quality to suit just about anyone's needs (i.e. Graphic Artist, Programmer, Gamer). The price point on this monitor is fantastic, while similar models of the same specifications from other companies range from $200-$300 more. For example: ViewSonic P817 at an average price of $1250.

iiyama has been around for over 20 years. They are the US subsidiary of iiYama Electric Corporation, Ltd. of Nagano, Japan. The company's track record is very good. They are recognized as a quality monitor manufacturer. So not to fear - you are not sinking your money into a company that has no idea on how to construct decent monitors.

Specifications

So as you can see, it has pretty much everything there that may need require adjusting; some you will probably never use. I found the factory defaults to be just fine, except for a brightness/contrast adjustment for my own personal preference. The menu is easy to use, and the manual explains the OSD very well, so you shouldn't have any issues here whatsoever.

DisplayMate Tests
Using the handy utility, DisplayMate, I went through all of its tests and was able to have a good close look at the display quality of the monitor. For all of the tests, I ran them at various resolutions and color depths. I have broken it down below into the various sections tested, and then summarized my findings.

Geometry & Distortion
This test displays various line patterns and geometric shapes, which gives you an accurate representation of the monitor's ability to properly display geometric shapes. The monitor performed excellent in these series of tests with no visible geometric inconsistencies found.

Sharpness & Resolution
During these tests, the monitor was put through various patterns and lines. The most noticeable thing you will usually see here is Moiré. Moiré occurs when there is interference between the phosphor layout and the video signal. The iiyama has an adjustment to compensate for this, and it did a fairly good job of it. There was a small amount of Moiré here, less than that with the the Pro 450. I had corrected this by adjusting the Moiré OSD control.

Screen Pixel Resolution
This test is similar to the Geometry test. It displays various line patterns and shapes. Here again, you are looking at the Moiré effect - jagged lines, rippled effects in the images, and lines that start to mesh together. Some of the patterns brought out the Moiré effect more than others did. Finding a monitor that does not display this effect in certain patterns is not an easy task.

Color and Gray-Scale
Now we get into the monitor's ability to display colors. One of the most important things to look for here is misconvergence. Misconvergence is essentially the misalignment of the red, green, and blue electron beams. The 510 performed very, very well here. There was a minimal amount at the edges of the screen (where it's most common), but nothing that causes visible problems elsewhere.

Text Test
Setting it at various resolutions, I loaded text documents into Microsoft Word, and Notepad. I examined the clarity of the text on different colored backgrounds. Text was clear and sharp, at all resolutions up to 1600X1280. I found that anything above that, text gets too small for proper use.

Resolution Test
Here, I simply tried every resolution up to the monitor's maximum, 2048X1536, and looked for defects and clarity issues in the display. In my opinion, anything above 1600X1200 for text starts to get unreadable for my eyes; although, the monitor performed extremely well right up to its maximum 2048X1536.

Support & Warranty
The monitor is covered for 3 years parts & labour. The average turn-around time for a monitor repair, providing there are no parts issues, is approximately one week. If you purchase the VisionCare warranty, which is $129.00 for this model, then iiyama will ship a replacement monitor to you within 48 hours. That's yours to keep at no cost. It seems that iiyama is willing to provide consumers with good support.

Conclusion
It's big, it's bad, it's a 22" monitor. The clarity and quality of this monitor is just fantastic for the money. With prices around $999 for a monitor of this size and quality, you can't go wrong. Something to consider when buying a monitor of this size: you are going to need a high quality video card with a decent RAMDAC to get the most out of it. For testing purposes, I used the Matrox G400 MAX, which gave excellent results in all resolutions, because of its crisp image quality and 360Mhz RAMDAC. So be sure to keep in mind the quality of the video card you are going to use with a monitor of this calibre.
