Dear developers, I have a GTX 1650 card installed on a Debian 10 machine with version 460.39 of the Nvidia driver. It’s connected via an HDMI cable to a Samsung T27A550 TV which has 1920x1080 resolution. The card is working fine at 1680x1050 however at 1920x1080 the screen becomes pixelated.
Before I installed the nvidia drivers I was using, if I’m not wrong, I was using the resolution of 1856x1392. Since installing the drivers this resolution no long appears as an option in the monitor control panel or nvidia-settings. I tried adding it with:
xrandr --newmode “1856x1392” 218.06 1856 1992 2192 2528 1392 1393 1396 1440 -HSync +Vsync
xrandr --addmode HDMI-0 1856x1392
but I get the following error:
X Error of failed request: BadMatch (invalid parameter attributes)
Also tried setting the ViewPortIn, ViewPortOut and Panning in the advanced Display config of nvidia-settings. ViewPortIn and Panning get set however ViewPortOut does not. It fixes the pixelation when applied however the screen is distorted.
I also tried various things with /etc/X11/xorg.conf, although I’m not even sure if the file is being used.
Can anyone please offer advice on how I can achieve the screen res of 1920x1080 or 1856x1392?
