Cables can make a difference. If you’re running HDMI 2.1 to get full HDR video and uncompressed HD 5.1 or 7.1 audio, then you should use a certified cable because it’s a lot of information moving across a cable very quickly. I’ve tried cheap Amazon cables before and they fail. They get too hot and the devices lose handshake and shut off or throw errors. But once you have a cable that’s rated and certified for your intended use, it’s not going to get much better.
