Acer is planning to launch the fastest gaming monitor on the market. As spotted by KitGuru, the new Nitro XV252Q F leverages a 25-inch AHVA panel by AUO that’s capable of reaching an incredible refresh rate of 390 Hz when overclocked—30 Hz faster than premium displays such as the Alienware AW2521H or ASUS ROG Swift PG259QN, which max out at 360 Hz. Pricing and dates of availability are unknown, but Acer’s Nitro XV252Q F will feature a response time of 0.5 ms G2G and include support for AMD FreeSync Premium.



That’s very fast https://t.co/oqhqIGuYjn— PC Gamer (@pcgamer) April 26, 2021



The 400nits of brightness and 1000:1 static contrast ratio combined with an 8-bit colour depth allow the monitor to cover 99% of the sRGB gamut. The...

I'm sitting here thinking... I have a fairly high end system. Not extreme top end but up there. And these monitors are so far beyond what I could drive I fail to see the value.

Do people with 5900x systems running NVME PCIe 4.0 drives in Raid 0, with DDR4 4000mhz ram, and 3090's or 6900xt's actually push these numbers in games... Well I guess if I played Counterstrike or some game that was known for FPS it would be different... I guess I didn't think of that.

Actually if you're like me and play old games where your framerate is in excess of 400fps, such a high refresh rate would actually be appreciated. For modern games though, yeah it's pretty useless. Unless you like to run your games at a low res and turn all the settings down. 165Hz covers me pretty well for most games I play.
 
Biggest issue is that it's a TN, and before that even, that it's an LCD.

I assume this is the 'last hurrah' before the OLED gaming monitors arrive.

I can NOT stand TN panels!!! Those are always the first ones to reach higher refresh rates though.

I'm 50/50 on them. The latest ones have a pretty wide 'safe' area and otherwise are pretty close to IPS panels. They look better than VA panels to me in that regard actually.

TNs biggest problem is the history of really terrible TN panels more than anything else, like laptops that you can't even read unless they're perfectly perpendicular to your eyes. Nicer ones have been available for some time that don't suffer that problem and are really as good as your average VA when it comes to viewing angles.

Iiyama had quite a few TN monitors set up for professional color work too!

You could just frame cap the old games. (or use DSR to increase quality and slow things down)

I recently played the original Dishonored in 8K DSR on my 43" 4k screen, and it looked quite nice, especially since the original game had pretty bad AA options.

There are arguments to be made about where the border beyond which no one can tell the difference in frame/refresh rate lies (for me it's probably 100-120hz somewhere) but 390hz is clearly well beyond the level where it makes absolutely no difference at all.

Yeah I sometimes I do cap the framerate, no need to have the GPU running full-bore all the time, and it can save on power usage and heat output. Some games have a built-in cap, like Doom 2016 won't go above 200fps, and Ion Fury maxes out at 240fps. I just let them run at the in-game cap, even though all excess frames past 165fps aren't getting to my eyes. Other games like UT2K4 and UT3 I don't cap in any way cuz I love how they feel in terms of control and input response. Love those low frametimes.

And yeah for non-demanding games and old games I use DSR. When I was on a 1920x1200 screen, I used DSR for 3840x2400. Now on a 2560x1440 screen I use DSR for 5120x2880. Even at that res, some games are still so un-demanding that they still run with crazy-high framerates. See Halo Master Chief Collection.

This does depend on a lot of factors; for many, it's a function of the displays simply not actually being that fast across their color range. It's also a function of input lag that's not particularly well understood because of the obvious objective testing constraints, but I'd wager that this is the real reason for pushing up refresh rates, if there is one.

I can say that at 144Hz on a 'fast IPS', one of LG's Nano IPS panels, there's still a significant clarity lost just moving content around on the desktop. Fixing that isn't terribly useful of course, but I can say that there's definitely a utility to faster refresh rates when it comes to human <-> machine interaction.

You also want to set an in-game cap to ~3FPS below your refresh rate to prevent potential sync issues with Freesync/GSync, since 'sync' isn't perfect system-wide.

Heat output is another good reason; I do the limiting for sync, but also limit on mobile as well when the excess responsiveness isn't needed.
