Hello, everyone!

For a few days now, my second monitor has been stuck at a resolution of 1024x768.

When I run xrandr, I get this

Your second monitor is connected via DVI I think, do you use any converter dongle? I had the same problem, with my private ThinkPad with EndeavourOS, as well with my work MacBook Pro. With my system, I used the DVI connector of the monitor to then connect through HDMI. Connecting it directly to my laptop or my docking station cut the resolution back to HD, one USB dongle was able to translate in a way the notebooks connected with higher resolution.

If possible: try to use a direct HDMI connection or use the Display Port, maybe just to verify both monitors are working with the expected resolution.

Hi, yes, the monitor is connected via a DVI cable; it doesn’t have an HDMI port.

Unfortunately, I can’t test it on any other PC: what I don’t understand is why it no longer works. Maybe I should try a live distro and see if another distro detects the monitor?
