Windows 10: HDR: not supported

hello.

My computer can not use HDMI when i reinstall windows 10 and i want to know why that happen

:)

 

HDR won't enable!

I have the exact same issue. I'm running a Corsair One with a GTX 1080. I know my TV can output HDR but for some reason any time I turn it on, it immediately toggles back off.

There is no error message that occurs and when I run the Direct X Diagnostic Tool (Recommended by Microsoft here: https://support.microsoft.com/en-us/help/4040263/windows-10-hdr-advanced-color-settings), there is no actual value for HDR. The "HDR Support"
value simply isn't in that text file. It does not say "Yes" or "No" as there is no option whatsoever.

I have verified all of my drivers are installed correctly and ensured that I'm using HDR compatible HDMI cables and an HDR compatible TV (Samsung KS8500). There's no visible reason as to why this problem is occuring, but it absolutely is.

Update: I enrolled my PC in the Windows Insiders Program and now when I run the Diagnostic Tool, I do have a listing for "HDR Support: Yes" but when trying to turn on HDR support, the setting still toggles back off.

 

I could turn on the HDR and WCG setting on initially today when I connected a new HDR TV.

Hello,

Thank you for writing to Microsoft Community Forums.

I understand that you are unable to turn on HDR and WCG color settings in Windows 10. This issue might occur due to incompatible drivers.

I suggest you to roll back the display drivers and check if that helps. Refer the steps mentioned below:

1. Press 'Windows
+ R' key together on your Keyboard.

2. Type 'devmgmt.msc' and hit enter.

3. Expand the display adapter option from the list.

4. Right click on the driver and click on 'Properties'.

5. Click on 'Driver' tab and check for 'Roll Back Driver'. If the roll back option is available, roll back the driver and restart the
computer.

If you are still facing issues with color after enabling HDR on your PC and if you’re using an HDMI connection and your display supports HDR over a DisplayPort connection, use DisplayPort instead to connect your PC and display.

• If HDMI is your only option, use that, and then do one of the following:
  

Reduce the frame rate

• 1. Select Settings > System > Display > Advanced display settings, and then select Display adapter properties.
  2. In the display’s Properties box, select the Monitor tab, select 30 Hertz for the Screen refresh rate, and then select OK.

- OR -

Reduce the resolution

• 1. Select Settings > System > Display > Advanced display settings, and then select Display adapter properties
  2. On the Adapter tab, select List All Modes.

In List All Modes, select the setting that includes 1920 by 1080, 60 Hertz, and then select OK.

Hope it helps.
