I have a 4K video demo I downloaded in an MKV format that does not automatically trigger HDR on my 940D. All the other HDR demos I downloaded do. If I laboriously manually select HDR it looks incredible. But I want to add it to a looping playlist of HDR video demos to show off my TV and cannot if it won't trigger HDR.

Is there anything I can do to make the file trigger HDR?

Thanks!
