Set the DisplayPort version in the G9’s on-screen menu to 1.2, replug the cable, and check whether xrandr shows that DP output as connected.
If it still shows disconnected, replug the cable and right after run:
sudo journalctl -k -b | grep -i -E 'nvidia|drm'
Look for link training or EDID errors on that connector.
Also run cat /sys/module/nvidia_drm/parameters/modeset and confirm it returns Y.

Booooo. Prime example of why you don’t ask an LLM for actual information. Samsung Odyssey G9 cannot drop to below v1.4, not to mention any display port mode over 1.4 should understand mode, so this isn’t necessary. There is no ‘Y’ in /sys/module//modeset, it is 0 for disabled, 1 for enabled, and 2 for headless. I know you think you’re helping, but it’s just muddying the water. STOP ASKING LLMS FOR ACCURATE INFORMATION.
