so input "15" is already listed as being for DisplayPort-1.

is your monitor using 15 for USB-C instead @daiwa233 ?

Thank you for your work.

Yes, my monitor which is AOC U27N3C using 15 for USB-C instead.

I have an AOC U27N3C too. It should be noted that 15 is not always for USB-C. When you use USB-C and DP at the same time, 15 is for DP particularly. I tried to program to find out what value is for USB-C in this scene. Unfortunatley, there is no solution between 0-255. I guess you use HDMI+USB-C, so 17 is for HDMI1, 18 is for HDMI2, and 15 is for USB-C.
