I've just installed Ubuntu on my desktop, and I've installed the nVidia drivers by using the ubuntu-drivers
command. When I plug the HDMI cable on the GPU slot, though, the desktop image becomes larger than my TV. Here is an image. The selected resolution is 4096 x 2160
, the same resolution that works perfectly when the HDMI is plugged on the motherboard. The output of xrandr -q
is:
v@v:~$ xrandr -q
Screen 0: minimum 8 x 8, current 4096 x 2160, maximum 32767 x 32767

The same problem persists when changing the resolution to 3840x2160
. My TV is properly adjusted for a 16:9 ratio. How do I fix this problem?
