Do you have a Ultra HD Blue Ray player? Such a disk doesn't play on a normal Blue Ray player.
I have got a problem playing a blue ray disc, that is also HDR (It is a Christmas gift and luckily there is also a "normal" Full HD Blue Ray disc in the box which I can play with no problem). The disc claims, that for the full HDR experience I need HDR compatible UHD TV, Ultra HD Blue Ray player, and High Speed(2.0) HDMI cable.
I knew, that my UHD TV has only HDR+ technology and is not HDR compatible, but I thought I could still watch the movie, just not see the best picture. Instead, the TV claims it lost the signal of the Blue Ray Player, and tells me to turn it on, and turns dark, whenever I try to play the disc. Is it utterly impossible to play the disc, or is there a workaround? Could it just be that my HDMI cable is not 2.0? (I am not sure) If I make sure it is 2.0 cable I still could play the disc, or I would in all case need a new TV for that?
