Nothing new, happens frequently when new consoles with (relatively) new tech appear. X360 launched without HDMI.So many caveats at the start of this generation (for both systems)!
Isn't it a VRR issue, and the PS5 doesn't (currently?) have VRR?
Either way, it is an issue with the AMPs and the manufacturers are aware.

Watched this earlier, the Xbox sends it's 4k120 signal compressed which the receiver can't handle, whereas the PS5 send it uncompressed.
Or something
Vincent says it's a hardware issue not software, but we'll see if something happens
It's been so frustrating this generation trying to get all of these HDMI 2.1 things working out. I got a new LG CX and thought I would be okay, then learned my receiver didn't support earc and that the HDMI 2.1 problems meant that getting a new one wasn't going to work either.
I think even when my new receiver gets here (Denon X2600h) I will need to use 7.1 pcm to avoid audio delays.

DSC is lossless compression.You mean after all this I'm not getting uncompressed pixels after all?
Does using arc definitely cause a delay? Can you use optical for audio?
My CX arrives tomorrow and I terrified of unpacking it let alone HDMI issues

Yes - when I go in to the hidden video status menu on the C9, it shows full RGB at 4k 120hz on XSX.So Xbox is able to do full RGB 4k120 due to DSC? Interesting. I also didn't know TVs supported that yet.

It's an LG problem. DTS used to work OK when I had this on my C7, have you tried that?Honestly other people can explain it more clearly, but arc (not earc) doesn't output higher than stereo with my XSX and Onkyo receiver. If you have an earc audio device and you try to bitstream (for Dolby) you get a delay that you can't fix. I'm not even sure where the blame lies, but I think it's an LG problem.
So your only options are use PCM or try a sharc by thenaudio
Sorry, it went over my head :DI know - was just making a joke about that weird uncompressed pixels PR from a while back.
The PS5 currently only outputs a 32gbps HDMI signal due to sending a maximum of 4k120hz @ 4:2:2 Chroma Subsample (to simplify into a sentence, lower color and light resolution). The Xbox Series outputs a 40gbps signal as it's a full 4k120hz @ 4:4:4 RGB (no Chroma Subsampling).Isn't it a VRR issue, and the PS5 doesn't (currently?) have VRR?
Either way, it is an issue with the AMPs and the manufacturers are aware.
This is what makes it an issue, since Xbox is the only console that can do Atmos in games, and the only way to connect it to get all the new features and atmos is to use eARC. The latency with that set up is unplayable IMO. You do a roll in gears, and you don't hear them hitting the ground until your character is nearly back on their feet.There is eARC to solve some of these limitations but ARC has its own issues in my personal experience (audio latency, TVs not supporting all audio formats, etc).
This sums it up pretty well. If (when?) the PS5 gets a patch that lets you turn off subsampling you'll have the issue if you try to go through the receiver (unless they manage to fix it via firmware and go around the chip issue).The PS5 currently only outputs a 32gbps HDMI signal due to sending a maximum of 4k120hz @ 4:2:2 Chroma Subsample (to simplify into a sentence, lower color and light resolution). The Xbox Series outputs a 40gbps signal as it's a full 4k120hz @ 4:4:4 RGB (no Chroma Subsampling).
It`s not though ? According to the video it is an issue when using compression in the display signal. The RTX 3080 managed 40Gbps just fine.
The Xbox Series uses Display Stream Compression (DSC), a lossless way of obtaining its HDMI 40gbps datarate. PlayStation 5 achieves an HDMI datarate of 32gbs, which is achieved by using a Fixed Link Rate (FRL). The Xbox achieves a better fidelity image (full 4:4:4 vs 4:2:2 Chroma Subsampling on the PS5), but it seems 2020 AVR systems have a hardware incompatibility and are unable to resolve the signal from devices that output a full DSC signal, in this case the Xbox Series).Watched this earlier, the Xbox sends it's 4k120 signal compressed which the receiver can't handle, whereas the PS5 send it uncompressed.

In my experience, using ARC introduces audio latency. You can use optical output from your TV and send it to your AVR. It won't support the lossless surround formats that a direct HDMI connection to your AVR can provide but it will have the same capabilities that ARC has (with no audio latency to boot).Does using arc definitely cause a delay? Can you use optical for audio?
My CX arrives tomorrow and I terrified of unpacking it let alone HDMI issues
Yep. To elaborate: ARC (not eARC) is practically identical to optical in regards to audio support (uncompressed stereo or compressed surround sound), albeit with the additional downside of introducing extra audio latency.Honestly other people can explain it more clearly, but arc (not earc) doesn't output higher than stereo with my XSX and Onkyo receiver. If you have an earc audio device and you try to bitstream (for Dolby) you get a delay that you can't fix. I'm not even sure where the blame lies, but I think it's an LG problem.

I was looking into HDMI2.1 receivers a while back but they all seemed to only offer one 2.1 port? I have both consoles so that wouldn't have worked anyway...

Same difference; your Denon 4700h can support one HDMI 2.1 device at its full capabilities (e.g. 4k120hz VRR, 8k60hz, etc).huh? I'm confused by this. My Denon 4700h has 8 HDMI inputs, but only one is 8K compatible. Is this what you're talking about?

Yeah that seems incredibly shortsighted by the AVR makers. Some TVs has the same problem as well.Correct, all 2020 AVR systems only have one HDMI 2.1 port.

There is no good way right now to play at 120fps and with atmos on Xbox.
I don't get latency on PS5 when playing blu-ray discs with atmos support via eARC, but of course it doesn't support atmos in games right now.
DSC, a standard developed by VESA, uses a low-latency algorithm to generate a visually lossless compressed image. Keep in mind, the term "visually lossless" does not equate to "mathematically lossless". The DSC is a high-quality codec which is mathematically lossy, but the loss is not perceivable to the human eye.
Yeah 2021 is when I'll look into actually upgrading my tv.These Gen 1 HDMI 2.1 issues are why I skipped the LG CX, as badly as I want/need one right now.
Seems like every issue is hardware and will only be fixed by the release of 2021 revisions. So I wait until next year.

I just bought the V4A. With the PS5 I only got 422 with it. So I just use eArc and plug everything into the tv and it works fine.The 2020 Yamaha RX-V6A and RX-V4A have 3 and 4 HDMI 2.1 ports respectively. Still affected by the same HDMI 2.1 bug though.
I keep finding DSC described as "visually" lossless, which just sounds like spin for lossy.

Can 4K120 HDR 4:4:4 not be reached without it? Why implement it?

The HDMI ports on the LG CX is capped to 40gbps (vs. the full HDMI 2.1 bandwidth of 48Gbps). This could be problematic for 12-bit content down the road. The other issue with the LG CX is that it does not support DTS:X over eARC.
It's not an issue with the Xbox, it's an with the receiver which can't deal with the HDMI 2.1 standard of DSC.Curious if this will be fixed like the Blu-ray player app is based on Vincent's video.
