The setting "auto display hdr" in MPC video renderer just don't turn my display's hdr mode on automatically
However, the default player of win11 would do that properly when watching in full screen
It used to be fine until today for some reason I reinstalled the k lite codec with just install codec for mpc hc option on
I have tried to reset the settings and all fixes offered in codec tweaks, sadly none of them worked

Enable "use Direct3D 11" in options of MPC Video Renderer. That is required for the HDR switching.

Also update your AMD graphics driver. Some of the previous ones had a bug that could crash the driver when doing HDR switch.

In internal LAV Video Decoder settings, also change hardware decoder from DXVA2 Native to D3D11 for optimal performance with renderer setting change.
