You could also try using KDE Plasma instead of Gnome, which survives GPU resets.

No I can’t move my mouse to the external monitor.
Do you mean that it stays on the internal display, or that it doesn’t show up on the external one?
Or to ask it differently, can you move a window where the monitor should be?
My laptop detects the monitor correctly so it shows up in the KDE plasma display configuration but the monitor is not getting any input.
So the system thinks it’s enabled? Can you move the mouse cursor to it?
That’s not right. Most monitors use 8 bits per color / 24 bits per pixel, though some are still using 6 bpc / 18bpp.
HDR doesn’t mean or really require more than 8bpc, it’s more complicated than that. To skip all the complicated details, it means more brightness, more contrast and better colors, and it makes a big difference for OLED displays especially.
