Here's a firestorm of uncommon ferocity in the CE industry.



The short version is that devices that use uncompressed video (the latest and greatest XBox, PS5, nVIDIA 3000 series display cards) can't be passed through by any of the HDMI 2.1 "capable" Denon, Marantz and Yamaha AVRs.

The rumor is that the PS5 may be able to send compressed video but otherwise, gamers will need to plug their consoles/computers directly into the TV and use ARC for sound.

Those who thought they could avoid CEC are in for a battle as ARC usually requires it to be enabled.

Speculation is that this problem may not be solved (other than using a direct-to-TV connection or reducing frame rate) until 2022.

Vincent Teoh also lays the blame on the Panasonic chip used in these receivers, but points out it’s not the same Panasonic that makes TVs since they sold the chip business.

I’m not too worried since I’m not planning on getting a next-gen gaming console, but it does make you wonder what other shortcomings their HDMI 2.1 might exhibit. Also, my C8 LG doesn’t do 2160p120 so a non-issue for my current setup.

I don't understand the hate around CEC. I use it in several of my setups and love it.

The hatred comes from the fact that some well-known companies (You know who you are, Samsung and Denon) are perennially sloppy about their implementations and the HDMI group is relatively lax about compliance. The upshot is that CEC too often doesn't behave as it should and there's nothing the end-user can do about it other than disable it (assuming that the manufacturer thought to make that a working option).

HDMI compliance up to now has been a matter of if you have a unit that passes testing (i.e. a Blu-ray player), you don't have to test similar pieces (any of your other Blu-ray players) going forward.

That's the part that I don't get. I have 4 different Denon receivers that are from 1-5 years old in various setups and all work very well. I also use it on several TVs (Panny, Pioneer and LG) without AV receivers and haven't had any issues. Strange that others have so many.
