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.

Take a look at HDMI versions in wikipedia and select cable accordingly.

Don't go with "cheapest" advices as you might buy cable that only capable to FullHD@30Hz, which I think not what you want.

Also, if your card and TV have displayport I'll suggest to go with that instead of HDMI. It just better and does not forbid open source realisations, like HDMI consortium does on HDMI 2.1.

Would you mind expanding on the open source realisations thing? I'm trying to get more into open source software but I'm a little too tech illiterate to understand the nuances, including what you just mentioned.

Just search for "amd hdmi 2.1 linux" to get full story.

In short - AMD wrote an implememtation for HDMI 2.1 standart for Linux driver, but it requires approval from HDMI consortium. They (consortium) denied it, so AMD couldn't ship it.
