Not all cables will work for the Cintiq Pro. Someone had a similar case to yours:
Gonna answer my own question.
I contacted wacom and they told me to get this cable, I tested it and it works fine.
although this is a very short cable and not easy for work station setup, it was recommended by wacom that the cable should not be longer than 3ft and have speed of 10Gbps for best performance, and this is actually shorter than the original cable that came with the tablet.
Edit: It said that StarTech was certified unlike the one you bought, I’m not sure if that makes a difference but if it worked for them it should work for you too?
