Details

It is dim on a win10 GTX 1650

Severity: -- → S3
Priority: -- → P2

ffprobe says: yuv420p(pc, bt2020nc/bt2020/smpte2084) where pc means full range

This is probably giving GetSourceDXGIColorSpace: DXGI has no support for PQ transfer function with full color range for BT2020 content and so needs to be handled specially.
