Any way to do similar for DP/HDMI? I've thrown away multiple cables cause I couldn't tell if the cable was just old and didn't support what I needed vs somehow broken. Looking at system report I only see `Graphics/Displays` which show's monitor capabilities but not cable. (I'm not actually sure if DP/HDMI advertise their capabilities in the same manner as USB 3).
Much like GP I've taken to labeling newly bought cables with a label maker to avoid wasting them in the future due to being unknown.
- greggsy 3y agoThere’s an okay video from LTT where they hire or buy an expensive tester for HDMI cables. Seemed to be a a bit of a dark art.

I mostly care as my current monitor requires HDMI 2.1/Display Port 1.4 and going through my random cables drawer was extremely tedious. As I had way to many cables.
- wtallis 3y agoDP and HDMI cables are mostly passive with no identifying chip, so the only way to determine their bandwidth electronically is to try to bring up the link at that speed.
