Getting & Setting a Monitor's HDR (High Dynamic Range) state

Recommended Posts

I need to temporarily disable HDR to display a menu system when an HDR video is playing.

It's been a bit of a chase finding out this is done, so I thought I'll share.

 

There's documentation of how to do it with C++ here:
https://stackoverflow.com/questions/53517128/query-if-hdr-is-active-on-windows

 

But even Delphi 10.3.3 is missing "Winapi.DXGI1_6.pas".

However,  Searching for this file led me to MfPack (https://sourceforge.net/projects/mfpack/), which does carry up to date header conversions.
