I want to control brightness in the DP monitor connected to Type-c port of the AGX Xavier devkit using to Type-C to DP cable.
Using the following topic as reference, I can adjust the brightness of the HDMI monitor.
In case of DP monitor, the ddcutil detect command is giving the output as “No displays connected” but I can see the UI in the DP monitor.
Any suggestions for debugging why DP monitor is not detected using ddcutil? and is there any other way to adjust brightness for DP displays?
