Can This Monitor use Nvidia DSR to Play Games at 4K?

[Denganim20]

So I plan on buying a curved ultra wide monitor with NVidia G-Sync and 144Hz. I would like it to be 4K, but it's not so I have a question. I have a 1080p ASUS monitor currently with G-Sync and 144Hz too, so I tried to use DSR to scale my screen at 4K. The image displayed on screen immediately looked way better than the resolution I had, and plus the DSR 4K worked with 144Hz which I was happy about.

I'm wondering if I can use this same method with a curved ultra wide monitor with 144Hz which has a resolution of 2560 x 1080p. If someone could confirm whether I can apply DSR to this kind of monitor and scale it to 3440 x 1440p (which I think is 4K for ultra wide monitors) and I could still keep the 144Hz I would appreciate that. Thanks guys.

P.S.- In case anyone is wondering the monitor I have currently is an ASUS ROG PG248Q monior and I plan to get a LG 34UC89G-B Curved UltraWide monitor.

That would be 1440p ultrawide, not 4K ultrawide, but yeah I don't see any reason why that wouldn't work. You'd need a pretty good GPU for 3440x1440 144Hz gaming though.

So what's 4K's resolution for ultra wide monitors? And would that DSR resolution still work with 144Hz?

4K ultra wide would be 5120x2160.

What graphics card do you have?

4K 21:9 would be 3840×1600 or similar. "4K" refers to the width, so taking a 4K resolution and widening it would give you a 5K resoluiton. 4K 16:9 (3840×2160) expanded in width to 21:9 would be 5120×2160, a 5K 21:9 resolution.

DSR will allow you change the resolution in multiples of your native resolution. Since all the "21:9" displays have slightly different actual aspect ratios you won't be able to get them exactly, but you'll be able to get something similar.

DSR 1.77x will give you 3413x1440, DSR 2.25x will give you 3840×1620, DSR 4.00x will give you 5120×2160.

Since DSR only affects resolution during rendering, the resolution sent to the display is still 2560×1080, it doesn't affect what refresh rates are available.

One last question I have to ask, will this system:
CPU - Ryzen 5 1600
RAM - 2400MHz 16GB
GPU - GTX 1080TI
MOBO - GA-AB350M-Gaming 3
Work well with a resolution of 5120x2160p? if not will it at least work with a resolution of 3840x1620p? I also do plan to play games at high-max settings.

 

[TJ Hooker]

A 1080 Ti is only just enough for 4K/60fps at high settings. So 4K ultrawide is out. 3840x1620 is doable, but if you're looking to take advantage of your 144Hz monitor with 100+ fps you may have to turn down settings a bit.

Also, your CPU may hold you back a bit in some cases when it comes to high fps (100+) gaming. That's one area where Intel still has a not-insignificant advantage.

I would personally just use the native resolution with higher settings, I think that would look better in most situations. Have you ever used DSR? I am personally not a fan, the performance impact is not worth what it does in most games in my opinion. I only use it in older games or games with no anti aliasing settings like mass effect 1. In most games I would prefer to just use some form of anti aliasing over DSR, I have found it very hard to get DSR smoothness just right it seems to either be overly sharp or Vaseline on the screen blurry.

I have tested 4K DSR on my ASUS ROG PG248Q monitor and I enjoyed it. I think I could do 3840x1620 with some PC upgrades, and my monitor would look better.
