Dolby vision apple tv+

Yeah, same problem here with DV getting a negative look. Hope Apple sorts this out.

I had a similar issue with my Oppo 203 over the summer when a firmware update caused the player to do the DV processing instead of just passing it on to the TV. It was completely messed up though and saturated with pink, not just a problem with dark scenes.

You could set the ATV4K to 4K SDR and set Match Range & Rate to Match Range. Then the box automatically switches itself to match the content. E.g. A Netflix Dolby Vision title will play in DV and an HD title will play in SDR ( The ATV4K’s home screen should also be in SDR which may be more pleasant.)

In my case, I have to switch to a different format than Dolby Vision with Match Range turned off since only certain Dolby Vision mastered titles have the issue. In SDR without match range, the problem goes away for me.

i have been working with both Apple and TCL to get this issue sorted. Appears to affect mainly Apple content as I can play the same DV content through the Vudu app on Appletv with no Issue for the same scenes.

Apple has turned DolbyVision back on again, however the issue still isn’t fixed. Seeing the exact same issues as described throughout this thread. I had hoped that when they turned DV off it was an acknowledgement of the issue and a temporary measure while it was fixed, but perhaps not. I’m not going to keep turning dynamic range matching off just to watch ATV+ content so i guess I’ll just stop watching it. No big loss, it’s mostly utter ***** anyway.

Yeah, I noticed it was back and then quickly disappointed they didn't resolve the issue. For a company that tries so hard to market itself as superior, they're not doing a very good job. I'm mostly happy with the device after breaking away from Apple for 20 years, but this doesn't inspire confidence that they're technically competent.

Meanwhile... Netflix, Amazon Prime, Disney+, and Vudu content with Dolby Vision all work without issue.

I have the same issue as you, Dolby vision used to play back perfect now none of my Dolby vision plays back properly from the Apple TV box including my purchased films, I get the same negative image on dark scenes as you describe even on Netflix. This is definitely an Apple TV problem as I have the recommended Belkin high speed lead I have also tried plugging straight into the tv with no success. If I use the app on the tv for Netflix I have no issues. I also have no issues with Dolby vision on my fire tv stick 4K. Another thing I have noticed is occasionally you will loose the picture, goes snowy white and it then comes back on I thought my unit was at fault when I bought it so I exchanged it the new one but this did the same. I have this week changed my AV receiver from Sony to Denon no improvement though. Personally speaking I think Apple need to contact Amazon and ask them how the implement Dolby vision that does work and at a fraction of the price.

I have been through full factory resets with both my TCL 55R625 TV and my Apple TV 4K and the problem remains exactly like before. Tech reviewers have said Dolby has admitted there are problems with DV over HDMI cables with some manufacturers and that firmware updates are needed. But some of these reports go back to 2017 so I don’t know if any fixes were ever released.

My Apple TV worked perfectly up until recently with Dolby Vision. Then I started getting the photo negative look on the switching to dark scenes whether watching Apple tv + or Netflix I can confirm I am using the best high speed 8k Belkin cable I have tested it running straight into the TV with the issue still being present. I have twice reset the box to no avail. I can confirm that I have run this through a Sony STR-1080 and my new Denon AVR-X3600h receiver both with no improvement to the result. This is very disappointing considering the price of this unit. I can confirm that Dolby Vision plays back perfectly through my LG TV app and also through my Amazon fire tv 4k firestick. I can confirm if I turn the Dolby vision off there is no problem but this is defeating the object Apple need to admit there are problems with this box and remove the Dolby vision compatible advertising or fix the issue. I am not Apple bashing as I have other Apple items ie iPad pro 2018 iMac mini 2018 but this issue needs fixing.

Looks like Apple has pulled Dolby Vision from most titles - with absolutely NO comment from their side..

Yes, same problem. Argh!!
