Basically, a part of display output is cut off only when my PC is connected to my 4k TV, what should I do?
I’ve a rtx 3070 with proprietary driver, the resolution is correct, 3840x2160.

Take a look in your tv’s picture settings and make sure that the aspect ratio is set correctly.

Ok, I tried do run this command

xrandr --output HDMI-0 --set underscan on --set "underscan vborder" 65 --set "underscan hborder" 128

but it doesn’t work, it outputs this

X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  11 (RRQueryOutputProperty)
  Serial number of failed request:  41
  Current serial number in output stream:  41

N.B. this is the output of xrandrd:

I am not using an Nvidia graphics card, nor am I using a TV as a monitor, so I have no way to test any potential solution. However, here’s what comes to my mind:

  • Does your TV offer an HDMI input setting, something like “PC Mode;” which might eliminate overscan?

  • Does the nvidia-settings utility offer an option for dealing with overscan?
