    eARC is "enhanced" ARC. It is newer and allows for "lossless" Dolby Atmos or DTS-X audio.

     

    Whereas ARC has Dolby Atmos and DTS-X, but its compressed audio.

     

    eARC has more bandwidth available to it, since I think it requires HDMI 2.1. So if you buy a 4K UHD blu-ray movie, and it comes in those 100GB multi-layered discs. Alot of that is uncompressed audio, and eARC allows you to pass the uncompressed audio to the Home Theater system.

     

    I am reading a thread on the HomeTheater subreddit, where a guy is giving a step by step lesson on how Dolby Atmos on Windows 10 is supposed to work with a receiver, and he's doing what you are doing, he is connecting directly from the RTX 3080's HDMI port to the back of the AV Receiver.

     

    But I can't do that because, I believe, I will lose more video features if I do PC > AV Receiver > TV.

     

    I think I may be coming up against a bandwidth problem, because through one HDMI 2.1 cable, I am trying to pass through: 4K with HDR @120Hz at 4:4:4 chroma subsampling and Dolby Atmos lossless audio at the same time.

    Well there’s rumors some of these HDMI chips can only do 40 GBps,  4K HDR 4:4:4 is over that 40 GBPs limit.

     

    Yave you tried 4:2:2 ?

    Looks like nVidia has the performance numbers for their cards.

    I hope its not one of those weird games where having 32GB of RAM actually seems to benefit the game. There better be assloads of ray-tracing for these framerates. There is no ray-tracing for AMD video cards, at least for launch.

     

    By the way, have you tested Dolby Atmos as your PC's HDMI port to your TV,and then to your TV connected to your AV Receiver through eARC?

     

    There's very few games that even advertise that they support Dolby Atmos through the PC, I tested it with Forza Horizon 4. And I'm getting anywhere from about an 1/8th to about a 1/4 of a second of audio lag. Its only noticeable because FH4 is a very fast moving game, especially when I'm playing it at 100-120fps with everything cranked up. I would have to crash into a fence or drive into water at high speeds for me to notice that the sound does not hit right at that moment, it arrives just slightly after.

     

    And Cyberpunk isn't going to move anywhere near as fast as FH4.

    I’ve tested ATMOS from my PC to receiver,   But I don’t need/use eARC.


    eARc to my understanding is more for like when you don’t have a receiver and use a sound bar.

     

    Or perhaps using the TV’s apps would be another use for EARC even when connected to receiver.   But I don’t use the TV Apps.

     

    My OLeD is 60 hz btw,   120hz still seems too demanding for most new games.   And most receivers are having HDMI 2.1 issues

    I wouldn't buy it probably, but the XFX 6800XT is the nicest looking one that I've seen.  If I did buy one, it would probably be that one.

     AIB prices are stupid tho

    iight cool.  Yeah, 3800 will be no problem for 3600mhz memory.  Those are decent timings too.

     

    I'm happy for you man.  That's a sick fucking PC you have there. :fblike: 

     

    *actually.. that's 2 sick ass PCs you have there :aitch:
