HDR not compatible with DELL S3220 certified HDR400

It is a 4K Premiium Certified cable, the xbox one had issues with hdr games and signal loss.

Have you looked through the Xbox Support channel on : "Do my TV and Xbox support 4K and HDR?"

If same problem persists, try other HDR apps like Amazon Prime, Netflix to test the HDR settings on videos. If you are still getting the same results for Xbox and the apps, I would lean heavily on your monitor not being capable as intended.

Yes, even the Xbox itself says that my monitor is compatible with 4k and HDR10 and both for gaming, as the auto-detect tool shows all the green-ticks except for Dolby Vision.

Monitor is certified VESA HDR1000, so it's definitely capable of HDR!

Can you please tell me if the variable refresh rate is working on series x with this monitor ????

Somehow, magically it worked! I have tried for a month with all the possible settings and gave up... I went to "Video fidelity & overscan" section of Xbox settings, set "overrides" from "auto detect" to "HDMI", and reduced colour depth to 8 bits. Then I turned on all the options (HDR10, Auto HDR, 50Hz, 12bits color depth...) and then switched back "overrides" to "Automatic" and it worked... So basically I didn't change anything, I have just recycled it from automatic to manual and back to automatic... Now it shows that "TV" is good for HDR gaming. Thanx!

To play games with HDR support enabled your monitor must support HRD10 for gaming. Some monitors only support it for video playback (movies and other video sources).

You can check if your monitor is compatible with under the "General 4K TV details"

If your TV or monitor is compatible with HDR10 for gaming you'll see the message on the screen:
