Hiya!
This is probably more simple than what I'm making into, but I want to be sure, so here we go:
Currently in the market for a good HDMI cable, however, I am curious as to what I need to know (as I know nothing about these cables) before buying one. So my use case for this scenario is a 3M long HDMI cable that will connect my desktop(Nobara or Bazzite) to my TV (that has Nvidia Shield). This is for easy access to couch gaming. My desktop has a RX 6700 XT card, but unsure about the specifications of the TV other than it being a 70inch one (can try to find this if its relevant), but I am not looking to stream 4k. So let me know what kinda specs/details i need to look for in a HDMI cable for this :)))
PS. I tried setting up Sunlight + Moonlight, but honestly seemed like a bit too much configuration for my liking, but might give it a go again later on. I've also only got access to medium-speed Wifi atm, so this isn't optional.
Calculator about HDMI and displayport bandwidth that might help: https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&mode=maxfreq&H=3840&V=2160&F=120&bpc=10&compression=dsc2.5x&calculations=show
As you go up in complexity like 4k and 4:4:4 HDR, you will have to pay more attention to HDMI bandwidth and cable length limits.
Look for "certified" premium or high speed cables.
