The short answer is: Only if you own an Xbox Series X, and a brand-new TV. As I write this, there is a growing number of Xbox Series X games that support this optional mode -- Halo Infinite and Fortnite, to name a couple -- but the advantages of 4K/120Hz over 60Hz are minimal as far as I've seen at this point. Future games and even video sources may make the differences clearer, and that's why you may want a receiver that's fully compatible. If you do buy an older receiver, you don't care about the Xbox Series X, or don't want to send your 8K model to the shop, you can always hook a fancy new console directly to the TV, then use eARC to get audio to the receiver. However, despite the mess that AV receiver manufacturers have found themselves in over the last 12 months, there is one thing the aforementioned models have in common: great performance.
