Question Force ultrawide resolution in a 16:9 monitor (nVidia)

[strelok49]

I have a 27" 1920x1080 display and I can create and run perfectly well 1920x810 resolution. Even the 21:9 scale works fine. Then you will ask yourself: "well, but what you need from me?"

I would like to use a higher resolution than the native 1920x1080, since it's a 27" display and native resolution is terrible for gaming. Example 2560x1080. And yes, I can play at 2560x1440 (16:9) using DLDSR perfectly well and works really great.

Fun fact: when I had a AMD card (different monitor, but still 1920x1080) in the past, I could play at 2560x1080 easily with correct scale.

On nVidia CP I can create 2560x1080 as a custom resolution and it works, but the scale is completely wrong and stretched. Change the scale on nVidia CP changes nothing. I've tried all of it. When I create 1920x810, boom, I don't even need to change anything on scale and works perfectly fine with perfect 21: 9 scale.

By the way, I have a RTX3070TI with the last driver.Any tips? I should try CRU?

Playing around with this, it looks like my monitor thinks it's getting a 1920x1080 signal, no matter what I set in NVCP. So it looks like you have to see if CRU can help.

Yeah, now you saying it's very clear. When I try to use 2560x1080, it looks like 1920x810 vertically stretched. I think it's a software limitation. I will learn more about CRU and try it. Thanks!

Delete your custom resolution you made. Better to over on the left in Nvidia control panel click ----Manage 3D Settings---

On the box that comes up go down to--- DSR-Factors---Click it. Check mark the 1.50x, 1.70x, 2.00x.

Close the Nvidia control panel. Now right click and change resolution from desktop. I find when you use a 1920x 1080 monitor and set resolution from desktop your faked fonts look less blurry than doing it from within Nvidia control panel.

This doesn't solve the aspect ratio problem that OP has.

Another possibility is the monitor cable. Standard HDMI may not support 2560x1080 (depending upon the HDMI version). I would suggest trying a Display Port cable. I would also download the latest driver for your GPU directly from the NVIDIA website. I wouldn't use the Windows drivers.

Although most monitors are plug & play, there are monitors that do require additional setup steps to get the best result. This should be addressed in the monitor manual.

You may be able to set the desired resolution and aspect ratio on the monitor (instead of or in addition to setting it in Windows Display).

Whatever HDMI version the cable was rated for may not matter as long as the cable was well built enough.

Also I tried to do what OP did with DisplayPort with no dice.

The bandwidth of HDMI cables has gone up quite a bit over the years. Here is a link to an article discussing the HDMI version spec's https://www.cmple.com/learn/a-complete-guide-to-all-hdmi-versions-and-specifications .

If the Display Port cable doesn't help, then that points to an issue with the monitor or with the operating system. The screen resolution is set in Windows Display. Windows 11 has some features in Display that may be of use. Here is an article discussing that https://www.lifewire.com/adjust-screen-resolution-in-windows-11-5194035#:~:text=Right-click on the desktop,the Display resolution drop-down. .

Is screen resolution in Windows Display set to 2560x1080?

Any monitor settings should be covered in the manual. It can be downloaded from the manufacturer website under the particular monitor.

Although the GPU is working, it may not be on optimum settings. You can try some older GPU drivers.

It's something with nVidia. I've just tried with a old AMD card and it works. It's sad. I need to upgrade my display to a new one with 1440p, something I don't want since it's a rare IPS with no backlight or IPS glow.

On an aside, I found out Intel dropped support for custom resolution on certain systems (or maybe in general) because "nobody really uses this feature"

le sigh.
