To check if the display is capable of HDR content on Windows 10, use these steps:

Open Start.
Search for dxdiag and click the top result to open the app.
Click the System tab.
Click the Save All Information button.
Select a location to save the output file.
Click the Save button.
Open the file with Notepad.
Search for Advanced Color and determine if HDR is supported:

AdvancedColorSupported – indicates display driver with support for HDR10 is installed.
AdvancedColorEnabled – indicates that HDR is enabled.

Quick tip: To search on Notepad, use the Ctrl + F keyboard shortcut, type the search query in the "Find what" box, and click the Find Next button.

Search for Monitor Capabilities and confirm it reads HDR Supported to determine that HDR10 is supported. If one or more requirements are missing, then you'll see the HDR Not Supported message.

Quick note: If you also see "BT2020RGB" or "BT2020YCC", then the panel is capable of HDR10, and the "Eotf2084Supported" indicates that the display is capable of HDR.

Once you complete the steps, you can check and enable high dynamic range on the screen and Windows 10.
