More advice for the home theater types:
If you are going to use an AV Receiver like I do, get one from the 2022/2023 model years which have HDMI 2.1 ports on all inputs, not just one or two. Don't be tempted to save money on an earlier model receiver, the early HDMI 2.1 receivers have had a lot of problems. It's not worth saving a few bucks to fuck around with the previous model years which might or might not work for you.
I have a Denon X3800H and it works great, it passes the signal from my gaming PC and my PS5 to my Samsung QN85C with no issues whatsoever. Recent model year receivers all support ALLM, my input chain always switches to Game Mode automatically without me doing anything on my PS5, gaming PC, and Switch. Most new receivers also support true signal pass-through, meaning that the video signal is sent untouched directly from source to TV and therefore truly adds zero lag to the signal at the receiver stage of the input chain.
