Problem in image of video on Plex HTPC

Server Version#: 1.40.5.8921 (Synology)
Player Version#: 1.66.1.215-6343cfaf (Plex HTPC)

Hi,
I have a problem in contrast with plex on some files but not all..
And i don’t know how to resolve this.

Can i have some help please ?

In the latest version of plex HTPC :

In the latest version of mpv:

I tried to update mpv-2.dll but now the latest version of mpv provides libmpv-2.dll and not mpv-2.dll anymore..

Thanks

Is the video in HDR?

Yes it is.

Ps : And i don’t have the problem on plex with Android on my phone.

libmpv-2.dll is just a renamed version of the mpv-2.dll :wink:
However, note, that newer mpv builds are incompatible with Plex players. If you like to change the mpv.dll use a build from my GitHub repo Releases · mitzsch/mpv-winbuild · GitHub

What are the settings set in Plex HTPC? Do you have anything set in the mpv.conf?
