Hi! I did some tests.
- When I deactivate the HDR in the zidoo and also in the tv, I no longer have the problem of lines
- If I deactivate HDR, the lines do not happen anymore, now the screen goes black, and the video player's counter goes to -300 min approx
- This problem of lines and black screen occurs when I play some mkv (not all) mostly anime. I reproduce the same Mkvs in vlc without problem
