I have a set of FSR 8k fiber optic HDMI cables and would like to know why they won't work on any of my displays? I understand there are source and display ends but none of them work when hooking up my laptop to my TV's. I have some old HDMIs that work fine. Wondering if there's a compatibility issue?
