So I get Q3279VWFD8 monitor today,compared to AG271QG (AUO 144Hz) image quality looks pretty same to me.I would say that luminance and color uniformity is maybe better on this Q3279,viewing angles are worse however its bigger screen size,I dont like matte coating,AG271QG light matte/semi glossy is better.
I want 32" QHD because I use CAD programs which can not scale and text on 27" QHD is too small for me.
But I also play competitive FPS games online where 144Hz is big advantage and difference between 144Hz is 75Hz is like night and day for me,so I will have to keep AG271QG...

This Q3279 is definitly better then crappy LG 32GK650F in terms of image quality (colors,viewing angles,sharpness).Of course it dont same have fluidity like 144Hz VA,but there is also not smearing.

Why the hell they dont take this BOE display used in Q3279 and they dont make it 120-144Hz with better electronics dammit.

G-sync can not be activated on this monitor ?

Gsync compatible works but your mileage may vary, for me on Win1809 and 419.67, I think 430.97 does the same probably, I have to off/on the monitor (while sending Async to it, such as running a game, pendulum demo, ...) after system/monitor has been in sleep sometimes, otherwise I get "double image" = not properly synced between GPU and monitor. On system boot it's 99.9999% fine and properly synced but not always after wake up from sleep. I blame Nvidia for their shoddy driver as this off/on with Async monitors resolving issues is not limited to this monitor only.

Dunno, for me the OD on XF270HUA was OK but people complain about it endlessly, I didn't use Async so there is that though, set 144Hz OD extreme live happily ever after until it gets packed to box and sent back to seller due to defects.
Maybe the newer GB with Innolux, there are threads about it, don't remember how the OD on it is in Async mode, no reviewer really bothers to test this as they would need to write their own app that runs in Async mode at specific frame rates instead of what ever app they use now for response time measurements (probably some generic off the shelf app running fixed max refresh Vsynced).

Yes it would be nice if they did more than 75Hz on this panel especially considering they don't mind pushing slow VAs to 200Hz yet they can't be bothered to do the same with IPS. On the other hand there may be issues in the available electronics and existing firmwares especially if they would take those from 27" IPS monitors. This panel is sold by BOE as 60Hz anyway, so 75Hz is nice thanks AOC, better than nothing I suppose.

27" 1440p is an odd PPI for sure a little too small at 100% scaling, it's also not much bigger than 24". It's not bad for gaming though, just not great for other uses.
Higher refresh is always nice, no doubt about that. The problem still is pricing and quality. 31.5" 1440p 144Hz+ or 4k doesn't exist yet on market, 27" only and those are one worse than the other, maybe now with 2nd IPS panel being available after many years of monopoly things will improve a little, or not, maybe it will take 3rd from LG to get things really going.

I'm OK with Async 73fps/Hz, if I lose in games it's not because of refresh rate. Granted the amount of pre-action is lower at higher refresh and it looks more connected. Still I don't have a problem in racing games or FPS games. Even most of my CS play for years I did on a laptop TN 60Hz, talk about torture lol. Refresh doesn't matter as much as some make it out to be close to deal breaking. It's nice but not worth crazy prices or crappy quality or both together. 240Hz would be grand for sure, and inorganicLED one thanks

Funny thing,looks like g-sync is working on Q3279 when AG271QG (g-sync module) is connected and monitors are clonned,now I can run pendulum demo smoothly.Nvidia

not so funny, gsync works on 99% freesync monitors.

no need for restarting on my model, and no flickering if you set freesync range 40-80Hz

No flicker here.

The VRR range upper limit is ignored. The fixed refresh rate is used as upper limit instead.

48-76 VRR is default, I run 38-76 but apparently not all units can do this and you may need 40-76Hz VRR. With 38-76Hz I get artifact free VRR from slow slideshow all the way to 76Hz after which sync goes off. With 40-76Hz you will have a spot around 38-40Hz that will not be synced.

There is a page on Nvidia somewhere to report issues with their driver but I can't find it, you can fill that to keep reminding them to fix the sync issue

BTW there are now:

LG 32QK500-W
Acer ET322QU

as well in 31.5" 1440p 75Hz Async IPS.

LG cost a lot more and is white. Don't think I will find any reviews, the Acer is not even available here yet, has VESA though and the Acer too. AOC you need adapter for VESA.
