Screen resolution wrong for monitor

**kotgc** · April 9th, 2023

I installed Ubuntu 22.04 and the monitor needs a Screen Display Resolution of 1280 x 1024 (5:4) Refresh Rate 75.02 Hz.
However, Ubuntu sets the Screen Display Resolution 1024 x 768 (4:3) Refresh Rate 60.00 Hz.
There is no option for the correct Screen Display Resolution?
Here's the GPU output:

Code:

ubuntu@ubuntu:~$

I installed the NVIDIA Settings and this doesn't offer the correct resolution.

You can set the resolution and refresh rate using Gnome Settings, but if you have no option for the resolution you want it's possible to force using a kernel parameter like this, video=desired_display:1280x1024@75.

Thanks, I ran the command and rebooted, however no change?
