Xbox Series X input delay

Updated:

I found that my soundbar SONY HT Z9F soundbar use HDMI 2.0 of which bandwidth is 18gbs connect to my TV using eARC port, so I changes my HDMI to

8K HDMI of which soundbar is 48gbs, and the delay improve a lot that it is hard to notice now.

I have tested. My set is

TV has enable eARC and set sound passthrough, HDMI BITSTREAM. XBOX SERIES allows PASSTHROUGH.

XBOX SERIES X --> LG 65 QNED90 --> SONY HT Z9F (eARC)

there is very noticeable delay on Atmos but don't have delay on any uncompressed sound like 5.1 or 7.1

XBOX SERIES X --> SONY HT Z9F (eARC) --> LG 65 QNED90

the atoms sound is sync with image, but I got a ton of delay on controller input, so I set TV image mode to Game Optimize,

and set game mode to FPS, the controller input delay is gone, but now, i got atoms delay back...

By the way, because my TV doesn't support DTS - X PASSTHROUGH, so when I connect XBOX to my soundbar, I could enable DTS X, and DTS X is working perfectly and there is no any delay comparing to Dolby Atmos.

Razer Blade 15 with RTX 2070 MAX Q --> LG 65 QNED90 --> SONY HT Z9F (eARC)

I don't have any input or atmos sound delay in this set.

So here is conclusion:

xbox series x has issue to passthrough Atmos content, even thought it is directly connect to sound bar, the sound or TV try to delay image to sync with atmos sound which causes a ton of input delay. But once you set the TV into low legacy input mode to get rid of input delay, the Atmos sound delay will be back.

And Razer blade 15 with RTX 2070 MAX Q which is PC is perfectly working at Atmos without any issue.

So this is definitely XBOX SERIES X ISSUE!!!!

I don't think it is either just trying to rule out all possibilities. Have you tried the console on a standard TV?

All games for sure.I have tried to put 1080 p 120 hz (normaly i use 1440 p and 120 h), i tried to change settings on the elite controller like the curve of the sensitivity, and i have seen a video wich say to download 3 application from the microsoft store (like determining the delay) but nothing of these thing worked. The only way i can play with a decent input delay is using a my friend brook wingman xb adapter and using a ps5 controller on it but every time i put the adapter i got a pop up wich say the adapter is gonna get banned on 23/01/24. I would not use the adapter if i can play with my elite controller but it's impossible for the imput delay thing

I have used a msi monitor too a optix mpg27cq but i have the same problem

I don't think is a display problem bc i have used the same one on ps5 but anyway is the samsung odyssey g5
