Dolby Vision tone mapping or raised black display errors in Apple TV4K on my TCL 55R625 TV. It only happens in very dark scenes and only with Dolby Vision content from Apple TV over HDMI.
It doesnt matter which Dolby Vision preset is used but Ive tried all different settings and a factory reset.
Ive tried different Match Range combinations but no improvement.
I have tried 3 different certified Dolby Vision high speed cables for what thats worth... And different HDMI ports directly connected to the ATV (18 inch to 3 foot HDMI cable lengths).
Im out of troubleshooting ideas so I just wanted to see if anyone has had any success if they have encountered this issue.
The Roku internal Netflix app plays Dolby Vision correctly so I think its a DV Apple bitstream profile issue over HDMI not being translated correctly by some displays.
Dolby Vision/Atmos over ARC
