Is that *their* first VRR display - or the first VRR display in a smartphone? Apple has had VRR rate displays in the iPad and watch for a few years now.
The ipad doesn't use a VRR screen, it cannot dynamically change framerate frequently and with the precision that a VRR display can. The ipad has 4 different modes, and will simply swap to the one that most closely matches the framerate of the content.
From what samsung announced at their show, this screen can dynamically adjust multiple times a second so can be on 10hz when you are on a webpage reading but as soon as the system detects input can ramp up to 60-120hz depending on the speed of the movement.
It also seems like this will act like freesync and allow the display to tie its refresh to each new frame of a game, greatly reducing input latency, although this is not confirmed yet.
I am fairly sure that the iPad Pro has a true VRR panel - for games in particular, it operates just as a G-SYNC or FreeSync monitor would, it matches the framerate of a game precisely from 24-120Hz, and is always dynamically adjusting itself depending on what you are doing. Scrolling a web page will crank it to 120Hz, pause to read even for a tenth of a second, and it ramps down to 30Hz.
As mentioned above, that's not VRR, it's switching between several fixed rates. VRR waits on each individual frame to be ready - this is then sent to the display which holds it until the next one is received.
But I literally said that in games, it waits on each individual frame to be ready and then sent to the panel - just as G-SYNC or FreeSync does... sooooooo...
No. Apple has said, without contradiction from Samsung, that their displays, both LCD and OLED use their own technologies. In fact, when the displays are magnified side by side, you can see the differences.
Samsung builds the displays for Apple using their manufacturing technology, but Apple has plenty of display patents of their own.
There is Difference between Oled and Super Amoled marketing wise, if its Super Amoled like Iphone X series then 100% its made and Designed by Samsung, if its Oled probably Designed by Someone else.
Andrei, if you ever get around to testing this display, could you give 24p and 30p videos a try on the MPV Android app?
If you go into the settings and enable the lua stats and display-resample options, MPV will display info such as the detected display refresh rate, vsync jitter and more while a video is playing.
I'm sure to be in a tiny minority, but butter-smooth 24p video playback is one of my favorite things about having a 120hz phone, and I'm curious to see if Samsung included a native 24p mode.
I personally cannot see why this has taken so long to come out my S20 Ultra will do 120mhz, its just a software switch in settings so why cant apps have the option to switch it on and off as the need arises eg games run at 120 and photos camera etc but all other stuff like menus or browsing default to the lower value
120Hz, not MHz, M stands for Mega as in one million hertz.
VRR lets applications change the required refresh rate on the fly. For instance a web browser could render content at a very low refresh rate (10hz) to save battery, and when the user starts to scroll it switches to 120hz to provide smooth input with low latency.
For this to work the switching of refresh rates need to be nearly instant, and to really save battery the lower end refresh rate needs to be low as possible. I’m not sure how the os wide toggle you’re talking about is implemented, and maybe someone here can enlighten us, but it is undoubtedly slow to switch rates and its lower bound refresh rate is probably 60Hz.
Doh MHZ! the change in menu is under display and its instant dunno if the screen is default at 120 and is reduced to 60 to save power but surely there must be an ability to get the power settings to switch it when in phone menu etc
We've gone full circle! The Panel Self Refresh spec intended for mobile device power reduction was modified to become VRR, now VRR has been extended to mobile devices to reduce power consumption!

Well how long does it take to adjust the frame rate though? Since there will obviously be latency in switching.Luminar - Wednesday, August 12, 2020 - link
Should be less than 16.67 ms if my sources are correct.NextGen_Gamer - Wednesday, August 12, 2020 - link

The iPad can have two different display rates at the same time though, which this can’t. I’ve got an iPad Pro, and it’s obvious when that’s happening.Duraz0rz - Tuesday, August 11, 2020 - link
First VRR display in a smartphone. They have VRR desktop monitors already.Vince789 - Wednesday, August 12, 2020 - link
First AMOLED VRR display in a smartphoneThe Razor Phone 1/2 had a VRR IPS displays

Maybe, but its not very well integrated in Windows or Linux yet. Also, few (if any?) VRR monitors can go down to 10hz.Luminar - Wednesday, August 12, 2020 - link
Pretty sure LG had a 0hz refresh rate in their G series phones. Like G3 or G4 era.drexnx - Wednesday, August 12, 2020 - link
they had Panel Self Refresh as early as the G2, but that just allowed the SOC to go to sleep while displaying static content.worked pretty well, but the G2 also had a big battery for its day. I really liked mine.
Duraz0rz - Wednesday, August 12, 2020 - link
Well, there's also very little need for VRR on a desktop besides gaming, whereas you're constantly power-constrained on mobile.Flunk - Wednesday, August 12, 2020 - link
Samsung display is Apple's display supplier... So if they haven't done it, Apple doesn't have it.melgross - Wednesday, August 12, 2020 - link

Funny that their channel 1 of oscilloscope doesn't actually contain any signal. Probably for photography only, but still interesting.damianrobertjones - Wednesday, August 12, 2020 - link

IIRC IGZO already had this?
