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

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

RDR2 never received a Series upgrade. The Series Snis playing the base Xbox One version. To access the One X version you would need a Series X

You should disable auto HDR on the console if it’s not playing well, and make sure to do the same on your TV. That’s the fake HDR where the tv guesses not the real thing.

It’s also possible the two are clashing

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

Check your TV settings: If you are using a TV to watch content on your Xbox Series X, check your TV settings to make sure that any power-saving modes are turned off. Also, make sure that the HDMI input you are using to connect your Xbox is set to a mode that allows for HDR and 4K content, if applicable.

Reset the display settings: You can try resetting the display settings on your Xbox Series X console. To do this, go to Settings > General > TV & display options > Video modes > Allow 4K > Allow HDR. Make sure that both of these options are turned on. Then, go to Advanced video settings > Video fidelity & overscan > Display > Calibrate HDR for games. Follow the on-screen instructions to calibrate your display.

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.
