Hi all,
Picked up an 85" bravia 9 a few weeks back, also picked up a Panasonic ub820 blu ray player all was working great with Dolby vision. Sent the player back and bought a new one that was region unlocked and when i have set it up Dolby Vision just no longer works. Ive enabked it in the player etc. I've tried resetting tv and player, made sure the hdmi is set to advanced and loads of other troubleshooting i found online, the seller of the player also took me through lots of troubleshooting. I also tested on a slightly older Sony tv which didnt work either. I plugged my xbox series x into both tvs and both have working dolby vision coming through(gaming not movies). I have been using 2.1 hdmi leads and have tried 2 different leads that i know work. Sent the player back to the company who sold it, they have plugged it into their display panasonic and DV works fine. The seller have suggested a recent sony update may be causing the issue but im stumped. Any ideas?
