This may be confusing or not IDK.\n\nIn a nutshell I finally got my PS5. So, it and my TV do 4k however my AVR does not do 4k. I believe the ARC channel will send audio but im trying to wrap my head around connections..\n\nFirst off. I have a Vizio PX-65-g1 which has one ARC channel HDMI. My AVR is currently an Emotiva 8100 Fusion (for now).\n\nHow do I do this to get surround and 4k? Is it possible?\n\nI'm thinking I could connect my PS5 directly to the TV's ARC channel (which I think is HDMI1) this should give me the 4k part and I think the audio would be sent optical from the TV to the AVR, right????? Then its all down to settings within the AVR\/TV\/PS5?\n\nCurrently I believe I have my AVR HDMI out going to the ARC in on the TV and everything connected to my AVR (nothing is 4k, till today) Hope someone can clarify or guide. Yes I do plan on updating my AVR at some point, hopefully soon. Waiting on Denon to release their updated version to make a judgment call but I digress.
