Questions regarding Sony X90L Settings for Dolby Vision/4K 120 HZ

[chander]

Hi,

I just hooked up my Xbox to Sony X90L and I am a bit confused with the settings or rather what I am missing.

According to the specifications & a demo I took with PS5 - the TV supports, HDR 10, HLG, Dolby Vision & 4K 120 Hz.

I am using this TV with the following setup -
Denon AVR x2700H, Xbox series S, Apple TV 4K 2023. All things are connected via DHIVIS Royce HDMI cables that are certified for high speed signal.

However -
1 - My Apple TV says it can't do dolby vision, or Croma 4.2.2.
2 - When I hook up the Xbox (hooked directly to the TV - HDMI 120HZ port) - the xbox settings say that the TV can not do HDR 10, Dolby Vision or 120 HZ.

What am I missing? I have gone through the TV manual, but I can't find any setting to enable this. Hence coming here. I can provide more info if any one here can help.

Thanks!

In my Xbox S, I had to go to TV and display options, video mode and turn on Dolby Vision. It is a check box. After this, Netflix on Xbox was displaying Dolby Vision.
