p65q9-h1 HDR 10 on Xbox series x makes screen dull and greyed

I'm having the same exact issue I have no problem displaying 4k but my HDTV does support hdr 10 but no matter what i do the hdr option is greyed out . This is rather frustrating as I would love to see what hdr looks like on my tv. I'm using the supplied
HDMI cable that came with my xbox one s. My tv model is a Hisense h8 series model number 50h8c

I assume you are using an Xbox One S/X, which supports 4K/HDR.

Some 4K TV's only display 4K/HDR through one HDMI port. Is this the case with yours? You can also check your TV settings to make sure 4K(UHD)/HDR/HDMI 2.0 is enabled over the HDMI port. Verify that HDR is enabled in your Xbox display settings (set Color
depth to 10-bit, ensure HDR is enabled in the advanced settings).

Since the PS4 Pro seems to be getting HDR color over one of your HDMI ports, what happens if you were to swap it with your Xbox? Do you get your HDR colors back?

I have a Xbox S and will soon be getting the X.

I have turned all HDMI cables on to the Enhanced mode to support HDR etc. I have tried swapping the hdmi over between the PRO and S ... The settings on the Tv are exactly the same as the PS4 Pro. There must be a setting on the S that I'm missing? It used
to work until there was an update about a year ago which then made everything on the xbox dull and dark, as if they have messed up the signal or something. Maybe the RGB colours are wrong etc?

The games I have tried are:

Sea Of Thieves - Dull dark and washed out

Forza Horizon 3 - dark and dull.

Zoo Tycoon - an absolute mess (Very dark and hardly any colour what so ever.

I can post pictures to show you the difference... I just want it to bloody work!

Thanks in advance

Xbox only support hdr on 4k so we that have a xbox series s and 1080p 1440p hdr 120hz screen cannot get hdr because its not 4k. On ps4 it works tho 1080p hdr.

yes they will.

even older games will be improved with HDR

from the original xbox to xbox series X

I have the same issue, I have a Vizio P75C1 and the picture is dull and lifeless when hdr is on and hdr content is being played. Is this a hardware issue or just a firmware update is needed from the xbox one?

Does anyone have an xbox one s and a samsung UHD player? with hdr turn on with both? is the xbox one s the only one with hdr10 dullness issues?

Ive tried every setting there is and nothing improves the dull color when hdr10 is active. With hdr10 off the picture looks incredible.
