Thank you but that still not helps at all.
HDR is recognized fine now everytime, but brightnes and contrast is messed up with HD/4K

Was messing around again for about 2 hours...

Full range (0-255)

HD ok:



HDR to dark/details missing:




Limited (16-236)

HDR ok:



HD to bright/to much contrast/grey vail:





How can i fix this?

Make sure everything is set to full range rgb...play the hdr file and pause - on your tv remote, make sure HDMI black level is  set to low (mine has settings for non-hdr and hdr).
