For those of you with LG Oled’s some settings for Xbox Series X best pic etc. Vincent knows his stuff.

Was just going to watch that as i got a YouTube notification.

Yup c9 cx b9 and bx. B models will obvs be darker as they are approx 20% less in nits brightness

Optical will still deliver pcm digital audio as a bitstream you only loose the ability for arc/earc by not using hdmi.

Basically your soundbar most likely wont turn on when your tv does and youll have to use a separate remote. No hard ship

Thought fuck it and removed the PS4 and plugged it into hdmi, found out what the hdmi-cec stuff meant in the series x menus, and now everything is working together!

Just need the new Xbox remote and my one remote solution is done I think?

Silly question, but are your cables all high speed? Just in case you are running an old HDMI 1.4 cable in the mix and you are getting a delay somewhere.

Also, in the Sound settings go into Additional and check:

eARC - On

DTV Audio Setting - auto

Digital sound out - try pass through if auto isn’t working

I switched to Auto after trying pass through and getting some issues on my Apple TV

Auto was worse. Do you think optical would be better as ive just bought a cable

Optical has less bandwidth, so max you will get is 5.1. If you are paying for an Atmos bar I’m guessing you’d like the extra speaker stuff.

Just to be clear are you getting a delay on built in apps too? Or just stuff from an external device?

And also check firmware updates for TV and sound bar and lastly, check this...

Also this fixed all my problems with my Xbox and Dolby atmos delay

Set sound output on TV to internal speaker > enabled Dolby Atmos > enabled AI Sound. (Did this as soon as I powered on the TV during intial setup, so I included the step here just in case it's part of the equation).

Set sound output to HDMI Arc > Output to Auto > Then made sure the sound output was BITSTREAM instead of PCM. (Noticable sync lag on XBOX One X and PC using Dolby Atmos content and youtube audio sync videos to confirm lag)

Set sound output on TV back to internal speaker, then disabled Atmos and AI sound.

Set sound back to HDMI ARC > Flipped output from Auto to Passthrough, to PCM, then back to Passthrough. Instantly the content synced and the issue was resolved. Confirmed Atmos was being played through my AVR on both XBOX One X and PC.

Lol, you only needed a 2.0 though for sound. Don’t want people to think I’m encouraging cable buying.

So if it's a delay then there's nothing else you can adjust, but if the voice is ahead of the lip sync then you can adjust on the TV

If it’s a 1.4 cable then it could be be. If the cable says high speed on the side then it’s not the cable.

Thing is once delay is in the sound. Due to the TV processing slowly. There’s no way to get it back. What I don’t understand is why you can’t then add a delay to the image output to sync that way. Guessing it’s not that simple or someone would have offered it as a feature.

Yup theres still a delay on audio. You can feel it on the series x especially. Gun shots are registered after the shot by a fraction. Apparently a sharc arc box will sort it but thats £150 so i will see if i can live with it first. I mostly play xbox in my 7.1 atmos headphones anyway.
