Xbox One displays no signal when using HDR

Microsoft locked hdr to 4k so if ur monitor dont accept 4k signals ( tick allow 4k box in settings must be selected for hdr) it doesnt work on 1080p 1440p displays usually only if they accept 4k signals. Because microsoft locked it since xbox one s and
one x. It is hard to understand why they not allow it now because they have xbox series s 1440p 120hz hdr console right?

Hi,

Thank you for the answer.

Yes, I can confirm I have HDR enabled in the video modes, along with auto-detect. I followed every step of the 4K & HDR troubleshooter on the Help page (even though it's mainly aimed at 4K), and none of the steps proposed worked.

I can also confirm that there is no setting to enable on the monitor, it just auto-detects the signal when it's being output.

Example: when I turn on my PS4, the monitor displays in Standard mode. When I open a game on the PS4 supporting HDR10 (such as Mass Effect Andromeda), the monitor will auto-switch to HDR mode and display that content correctly once the game menu gets displayed.
Nothing else to do.

On the Xbox One X, whenever I open an HDR game (such as Rise of the Tomb Raider) the monitor continues displaying in Standard mode, and I can't alter the HDR slider in the game's options since the feature is not being picked up. When I check the
4K details in the Video options, it's displaying that my display is not HDR10 compatible.

I have the exact same issue on my One X. Tried the Star Trek and Guardians of the Galaxy 2 (Both UHD discs with HDR). Games in HDR (Forza 7) look amazing but UHD movies look awful now.

Regular blurays look fine. My LG OLED C6 switches to HDR mode and displays info saying that it is receiving a 4K signal with HDR and BT rec.2020 so the signal is correct for HDR, but it seems that the Bluray software in the latest update has been messed
up so that it doesn't decode or send HDR image data correctly to the TV as it did before.

According to some support documentation, it seems you
must have a 4K+HDR display in order to enable HDR.

I suppose 1080p+HDR displays weren't a thing yet when the Xbox One S came out. A bit ironic since the game is rendered at 1080p anyway on the Xbox One S!

One thing to do for now is to submit your feedback to request HDR support for 1080p+HDR displays: http://xbox.uservoice.com Make a new thread with this request, or vote on existing threads if someone else already has
the idea. If a thread gets enough votes by the community, the idea will be officially evaluated by Microsoft and they may push it into future system updates.

Display HDR 1000 is a VESA Certification of HDR capability. This monitor having Display HDR 1000 means that it meets VESA's highest requirements for an HDR display.

This monitor should work beautifully for Xbox One X. You can see more information on the Display HDR ratings here.

Happy Gaming!
