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.

Unless you're doing something crazy, like super-long runs (like, across a whole building) get the cheapest thing you can find that's rated for the minimum spec you need (like, if you want 4k at 120fps or whatever, lookup which HDMI version is needed for that, and buy at least that). That means do NOT buy at any brick-and-mortar store, their markups are borderline illegal.

I'll drop another recommendation for monoprice.com.

Note that you’re not getting 4K 120Hz on AMD on Linux atm. It requires HDMI 2.1 and amdgpu won’t get acceptance from HDMI forum anytime soon. For that you need DP 1.4 -> HDMI 2.1 converter.

Is there a good reason they won't get acceptance?

Good reasons no, it’s about hiding HDMI spec and protecting some shit DRM

AMD wants to open-source the driver, the HDMI Forum doesn't like that
