Windows 10: Dolby Vision and HDR10+ are not available while displaying HDR content, although all...

I have tried several content, including games and videos in Dolby Vision, but when I connected my laptop to Dolby Vision supported TV via hdmi 2.1 cable, all the content displayed as HDR but not HDR10+ or Dolby Vision. Same content works just fine when displaying from usb. Laptop is HP Victus with Windows 11. The graphic card is GeForce RTX 4050. Dolby Vision is activated on Windows settings and Dolby Access. There seems to be no problem here. I have also installed Dolby Vision extension. I tried different media players including Windows's media players. By the way, there is no problem with Do

HDR10 content from PC not triggering the HDR settings on my display

Other than the Windows HD Color settings, is there something else I need to check for the computer to trigger the HDR display mode on my television?

I have a PC connected to a TCL 5-Series Roku television in my living room that supports both HDR10 and Dolby Vision. The HDR features work as expected with my PS4 Pro, Xbox One S, and Roku apps, but I am having trouble getting both HDR and SDR content to
display on my television correctly at the same time from my computer.

The computer is Running Windows 10 version 2004 with all available updates and has a Nvidia GTX 1050 graphics card with current drivers. I have followed all the suggestions on

this page.

With Windows HD Color turned off, everything is sent to the television as SDR which is to be expected. When I enable the HD Color settings, HDR content appears with the correct colors, while all SDR content is washed out, even after adjusting the brightness
slider on the Windows HD Color Settings page. The television has different display presets for SDR, HDR10, and Dolby Vision. The HDR modes are triggered automatically by the detected video signal, but no matter what changes I've tried from the PC, the television
remains in SDR mode.

I can tell that the television is not detecting an HDR signal because the available preset configurations change depending on SDR, HDR10 or Dolby Vision content detected. For SDR content, the presets available are Movie, Normal, Vivid, Sports, or Low Power.
When HDR content is detected, the available display modes change to Dark, Normal, and Bright with an HDR or Dolby Vision logo depending on the HDR type detected.

Both the Windows HD Color settings and the DirectX Diagnostic tool indicate that my display is capable of HDR.

 

Best routes to ensure HDR10/Dolby Vision content

I'm on Windows 21H1 with a HDR10+ Dolby Vision compatible 4K display via a good WIFI 6 connection. As of right now all my streaming content is viewed from Microsoft Edge current build. Windows settings show HDR is enabled and my tv input shows HDR 2160 res. Am I getting the most that I can via stock up to date Edge? Do I need to make other changes or use windows store apps.

 

Change label BT2020RGB or P2020 as Dolby Vision

Greetings!

I was having issues enabling Dolby Vision on my Windows 10. After following this article

HDR settings in Windows - Microsoft Support

I ran DxDiag Report. I found out that Windows 10 was telling me that my display was set to HDR, but when I went to DxDiag report I found out that I was not on HDR but Dolby Vision. The problem is that my Apple TV is able to display Dolby Vision logo when
the media supports it, but windows 10 does not display Dolby Vision logo at the time of using this setup. My diagnostic stated that Dolby Vision was operational but windows 10 display setting did not say this.

I would like to ask Microsoft to add Dolby Vision logo when this is enabled instead of displaying HDR. I also would like to have the option to go to display setting and choose between HDR, HDR10, HDR10+, and Dolby Vision.

Thanks
