Similar but no NVIDIA graphics card. It literally goes into āNo Signalā.
Description Similar to Geforce RTX 3060 Can't set refresh rate to maximum, monitor loses signal on driver versions above 550, the monitor reports āNo Singalā when its refresh rate is set to any higher than 60Hz. The monitor model is KTC H24T09P,...
If Windows offers a higher refresh rate (e.g., 1080p@120Hz or 144Hz) on the same system and monitor via HDMI, but Linux does not, then that might infer that these modes are not exposed by the Intel (i915 or Xe) driver.
If you have āedid-decodeā installed, you could examine the EDID from the monitor egsudo edid-decode /sys/class/drm/card0-HDMI-A-1/edid

There you go. The driver limits what is reported as available for whatever reason.

Is there a way for me to āmanipulate the EDIDā for it to work or have some way to fix it or this simply just a reading which is immutable?
Or perhapsā¦it will never be fixed, unless I file a bug report?
cat /sys/class/drm/card1-HDMI-A-1/edid > /home/dart/toshiba.edid
Of course you need to adjust that for your own machine ā¦ then feed it into wherever it needs to be ā¦ I forget where that is ā¦
It would be in the realms of experimentation. You could try adding a display mode with xrandr and then try invoking it. If it works it can be made permanent with an autostart script. YMMV.
One of many how tosā¦
