So I set up a PC and I have two horizontal and one vertical screen. I installed ubuntu 22.04 and installed “software & update”
$ uname -a

Using the Nouveau I’m able to get the right resolutions on each monitor but using the 525 two of the screens going through with DisplayPort cables are lower than max resolution, and one with HDMI is the correct max resolution, and this happens regardless of which monitor being connected through HDMI.
I’m thinking this is an issue with the driver since with using Nouveau I’m able to get the correct resolutions, so it’s not the cables.
I also tried to force higher resolutions through nvidia-settings but it wouldn’t let me change the output from the GPU, it was just scaling the lower resolution to a bigger screen which looked awful.
What can I do?
