Hi.
I am trying to have 2 screens with my orion o6n but the DP doesnt work. I am using the builtin GPU, HDMI is fine, detects the display correctly, but DP is not.
Detects a screen, but a 1080p60 but mine is a 1440p165, i have tried multiple DP cables and all have the same problem.
I had used the official radxa OS bookworm, Ubuntu 26.04, debian 13 with open source drivers, but nothing did work/
