External USB C Monitor not working

I'm experiencing the same issue here with a portable display. The Asus MB16AP which has an integrated battery. I cannot get the display to be recognized in display settings or display output from the PBP. The monitor is receiving a charge from the laptop.


I've tried flipping the USB-c cable and rebooting after each attempt, changing the orientation, etc as suggested above. I'm using an 18inch certified thunderbolt 3 cable. I have also tested with other more generic USB-c to USB-c cables.


My next steps are to see if the device is supported by the kernel, update/intergrate mainline if needed, and research dmesg output:
"[drm:analogix_dp_bridge_atomic_enable [analogix_dp]] *ERROR* Failed to disable psr -110"

I'm having a blast with this new PBP.



Really appreciate any input and suggestions.



Thank you.


From log, looks like this is a DisplayLink type monitor and not actual USB alt-mode DP type. The displaylink needs special driver to drive and not sure whether there is such Linux driver, and disadvantage is taking up a lot of CPU resource.
