Display Cropped After Installing NVIDIA Drivers on Fedora KDE with 4K TV (Wayland)

Hi everyone,

I’m having an issue with my display after installing the proprietary NVIDIA drivers on Fedora KDE (Wayland session). I’m using a 4K TV as my main monitor, connected via HDMI to an NVIDIA GeForce GTX 1080 Ti.

Issue:

After installing the NVIDIA drivers, the desktop appears slightly cropped — the edges of the screen are cut off (top bar and corners are partially out of view). This wasn’t happening before the driver install.

What I’ve Tried:

  • I’m using Wayland and would like to stay on it.

  • Tried to use xrandr to rescale the output:

    xrandr --output HDMI-A-1 --scale 0.95x0.95

    But I got this error:

    X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  7 (RRSetScreenSize)

  • Launched nvidia-settings, but the UI doesn’t show X Server Display Configuration, so I can’t change scaling or overscan compensation from there. (Screenshot of what I see attached.)

  • TV is set to “Just Scan” or “Full Pixel” (no overscan), so the problem doesn’t seem to be coming from the TV side.

Goal:

I’d like to correct the screen cropping and ensure the full desktop fits within the 4K TV display area — without switching away from Wayland.

Any tips on how to fix this under Wayland? Happy to share logs or config files if needed.

Thanks in advance!

I get :
wlr-randr --output HDMI-A-1 --scale 0.95
compositor doesn’t support wlr-output-management-unstable-v1

Yeah, sorry, apparently KDE uses a different Wayland implementation. (wlr-randr would work for Sway.) I’ve revised my earlier post.

I had the same issue and found that the fix was a config on the TV to set the scan to the screen and not allow it to extend beyond the screen edges. It may have been ‘just scan’ or something similar. I don’t see it right now since it has been several months since I connected this TV to my PC.

I note you said you already have used just scan so I have no additional info

With Intel UHD and a 4K TV it defaults to 4096x2160, which causes stuff to get displayed outside the screen border. The TV natively supports 3840x2160, and Intel renders fine with it when manually-selected.

I think there’s something with the Intel VBIOS choosing the wrong res as BIOS and pre-boot use 4096 too.

I’d make sure 3840 4K resolution is being used. If it was already used, I’d force a reduced-blank or some kind of custom refresh rate.

Afaik that (and other NV settings) aren’t supported under Wayland and are hidden (I’m thinking the idea is those settings shouldn’t be set from NVIDIA’s end)
