I have a home theatre. When I use a 4K disc on the home theatre dvd player the movie is too dark. It’s unwatchable. I can’t see the movie.
The theatre is beneficial for the speakers and surround sound.
If I use my TV and Xbox series X the 4K disc shows the colors fine.
On the projector and oppo dvd player it is too dark and unwatchable.
The setting on the DVD player is set to HDR.
