Based on the setup you are describing it probably will not matter unless you plan on running anything else through the AVR to the TV. The quality of the signal(resolution and FPS) will match whatever the lowest standard in the chain is. If the Set Top Box can only output 1080p at 60fps that's all you'll get regardless of if your TV is able to do 4K 120fps. If your TV and AVR can both do 4K 120fps I would connect them using the 8K cable and use the premium HDMI to connect the Set Top Box since most companies aren't providing cable channels in 4K at 120fps. This way if you want to connect a game console, 4K streaming device or 4K Blu ray player you done need to change the cable connecting your AVR and TV.
Sorry, there was a problem. Please try again later.Just use the higher resolution one for both ports to be safe.
