A:Answer This is accurate - the current HDMI 2.1 chipset in this receiver is unable to pass through 4K/120hz from a console like the Xbox Series X. It's possible to connect the console directly to your TV and have it pass audio to the AVR with eARC, but it's not ideal. This only affects 4K/120 output, so you could also drop the console settings down to 4K/60 ... but that's not why you got it, right? Denon claims to be working on a solution, but there's no word on what that means yet.
