Windows 11 automatically selects the optimal display mode based on the hardware and display capabilities. If your display supports Dolby Vision, the system may default to this mode due to its generally superior visual effects. This may explain why your system defaults to Dolby Vision rather than HDR10 after a reboot. The "Use Dolby Vision mode" option is a manual setting. If this option is unavailable, it may indicate that the system recognizes Dolby Vision as the optimal setting and has applied it automatically.
To test this, you can play content that supports Dolby Vision. If both the display and system correctly enable Dolby Vision, video playback will automatically switch to this mode, and you may notice related prompts or indicators on the display.
If you prefer to manually control this setting, consult the On-Screen Display (OSD) menu of your monitor or the control panel provided by your graphics card to see if options are available to disable Dolby Vision or enforce the use of HDR10. I understand it is essential for users to have the choice to enable or disable Dolby Vision. You can submit feedback to Microsoft through the Windows Feedback Hub, suggesting that they implement additional user control options in future updates, including the ability to manually enable or disable Dolby Vision. To do this, press the Windows logo key + F, which will directly open the Feedback Hub app, allowing you to provide feedback immediately. Yuhao L
