ASUS Readying a 144 Hz 4K Ultra HD Monitor
ASUS is readying with what could be the world's first 4K Ultra HD monitor with 144 Hz refresh-rate. The monitor features a 27-inch AHVA panel by AU Optronics. The monitor relies on DisplayPort 1.3 for sufficient bandwidth to push its advertised resolution (3840 x 2160 @ 144 Hz). There's no word on whether the monitor supports adaptive sync technologies such as G-SYNC or FreeSync. DisplayPort 1.3 support can be found on some of the latest GPUs, such as the GeForce GTX 1080 and the Radeon RX 480.

I thought that sharp images are given by resolution/ppi not refresh rate and that in games input lag>refresh rate. I guess i will have to try one of this 144Hz displays one day even though i don`t play twitch shooters.
I have a 3440x1440@100Hz monitor, and there is almost no difference between gaming at 100Hz and 60Hz on my old monitor. Also because I never used VSYNC either ways.
I was looking to get PG348Q or PG279Q from Asus, but the panels from AUO has been such garbage + g-sync random problems that don't want to bet with my money. I am interested on this, but I really need to see some favorable reviews first.
That doesn't include overhead of DisplayPort, the adaptive sync overhead (doubt that is much), and the HDR overhead (not sure how much that uses.
Edit: DSC is supposed to be 3:1 compression so...should theoretically be possible but only with DisplayPort 1.4. No Polaris for me! :cry:
Even today I would never trade away the guarantee of having above 75 fps for a higher resolution. Happy to game at 1080p and look at some jaggies than to lose 120 hz and the tear-free, super smooth action that comes with it. Gaming is all about *motion resolution*, and so much less about how detailed a static image can be. That is why for me high refresh panels > resolution and most of everything else.
The additional advantage is that high refresh panels just don't have visible tearing when you play with uncapped FPS either, they handle variable framerates so much better even without any kind of special sync (Vsync/Gsync/Freesync). You don't need it at all for anything that runs above 75 fps.
[1] AFAIK TVs do a whole lotta crapton on processing / filtering / yadda yadda on the image, often using several frames as reference and thus also buffering quite a bit for that, too. Hence the lag. Gaming mode in TVs that have it turns most, but not all of it.
Staying far, far away from that for gaming - been there done that :P
Every generations wafers get more expensive, and big GPUs get exponentially harder to make. Two small GPUs are easier to make and more profitable then 1 big GPU. DX12 has support for multiple GPUs, but it is a new API. Devs are not experienced with it yet. Dual GPU support will come, though, just like DX11. The last few years have been bad all around for games, not just in the dual GPU market. Broken games, delayed support draconian DRM, on top of brand new APIs. Give the industry a few years to figure out DX12, and dual GPUs will become a proper solution again.
And before anyone says "well game engines wont support it" UE3 doesnt support AA, yet every UE3 game I've played has an option for AA. Just because an engine doesnt support it out of box doesnt mean it wont work, or that it wont get widespread adoption once someone figures it out. One dev gets UE4 playing with multiple GPUs nicely, and everyone else will copy the implementation if they have any will to support the PC market. Devs that dont, well, that's no different then it's been for the past 10 years.
HDMI2.0a ports: 34.7ms
( 4k@60 4:4:4, 8-bit | 4k@60, 4:2:2, 12-bit | 4k@60, 4:2:0 12-bit)
HDMI 1.4 'Gaming Port': 17.7ms
(4k@60, 4:2:2, 8-bit | 4k@60, 4:2:0, 10-bit | 1080p@120, 4:4:4, 10-bit | 1080p@120, 4:2:2, 12-bit
So, IOW 2-3 frames...and in reality pretty much ALL gaming is going to account for three frames of lag (including from a typical wireless controller etc).
I don't find anything in that range bad at all; my old LG was 32-33ms and I found that fine as well. If I can keep lag under a few frames @ 60fps I'm totally happy, and can't really notice it, especially when using a controller. That said, I don't play competitive FPS.
I'm with whomever believes 4k @ 120 10-bit [HDR] with adaptive sync on large 'displays' (TVs) is the be-all, end all of these conversations. That said, I'm fine with whatever Vizio continues to put out until SOMEBODY picks up the displayport ball for 65'' screens. I, like certainly everybody else, hope that is in time for OLED to take center stage of our lives.
