Any idees for help me please?

What the best color spacee config on law video decoder for mkv uhd movies?

Thanks

Color space in LAV is already correct by default. Don't make any changes! Your problem is not related to colorspace, but HDR tone mapping is not done correctly by the TV.

First thing to try: select "PC mode" on your TV. That may fix the problem.

Second thing to try: Madvr options > Devices > HDR > Select "tone map HDR using pixel shaders"
Then Madvr will do tone mapping instead of the TV. With the peak nits value you can adjust the brightness.
