Dtto for video cables - once you get into 1440p/4k and high frequency rates or VBR, that HDMI 2.1 or DP 1.4 certifications start to actually matter.
What is worse is that the hardware tries hard to make it work even with noncompliant cable resulting in things like random flashes of black, or multiple random reconnections after plugging in the laptop.
Great, now you've got me checking our HDMI cables :) Is there an easy way to check what an HDMI cable supports?
I guess the same question stands for USB cables. I remember looking into that a while ago but did not find anything conclusive.
