my tv is 4k. its a cheapass one from walmart though

. 58 inch hisense roku 4k whatever
its whatever hdmi cable came with the 1TB ps4. since it wasnt the pro, it might not be as good a cable as that one, though
if push comes to shove i can redo the cables and just use the 2.1 that comes with the PS5. just didnt know if it would serve any purpose if my TV doesnt really pick up the 2.1. conceivably would have better bandwidth than my current cable but i dont know the specs on it
might be worth just redoing my wire setup. im probably going to have to yank the cable runner off the wall and just reinstall another one. theoretically the piece facing out should be able to slide off, but since i have it making tight turns along my angled wall, i have just about zero slack to try to actually slide the pieces. and no chance i can just try to push a wire through. would be like pushing a string
