Dolby Vision shows red screen

I have this setup:

Andersson L6530UHDS

Apple TV 4K 32GB

Both devices supports Dolby Vision, and this has worked perfect until recently.

Now using Dolby Vision on the Apple TV just gives a red screen and pink flicker on the TV.

Grateful for any tips or tricks.

Apple TV 4K, tvOS 13

Work with LG C1 Hello. Bought lg c1 tv. Connected to it Apple TV 4K. Connected via HDMI cable. On Apple TV I chose 4K Dolby vision 60Hz. When you start watching the TV screen, it starts to flicker and that's it. Impossible to watch and use. At the same time, Dolby vision appears on the screen, then disappears. If I disable HDMI deep color. Then it stops flickering, but Dolby vision and hdr are turned off. What to do? Why it happens?

Apple TV 4K Loses Connection With TV 4K Dolby Vision I am running a new Apple TV 4K via HDMI to a LG 2017 TV. I have turned on 4K and Dolby Vision. I have used 'Check HDMI Connection' and it comes back OK. I am using high quality high speed HDMI cables. When first turning it on, it seems to work OK. Then I might get a flicker in the video and sound. It gets progressively worse until I lose both picture and sound. Sometimes this happens when first watching a program. Sometimes it seems to happen when a program ends, and I go back to the menu and it appears that DolbyVision turns on? I reboot the AppleTV and everything works for the rest of the evening. Any suggestions? I got the AppleTV in December 2021.

Apple TV 4K with Philips OLED and Dolby Vision only 8 bit A reply to: https://discussions.apple.com/thread/250715577?answerId=251809450022#251809450022 Hello everyone, I wanted to reply to above post, but the topic was already closed. So I hope it is okay, if I start a new one :). I am using Apple TV 4K to watch content on my Philips 65OLED754. I have severe color banding when watching dolby vision content. The TV also displays 8 bit color depth instead of 12 bit. I couldn't find a solution so far. Even the main Apple TV menu shows color banding when set to dolby vision. Does anyone know a solution? I would be very happy :). Thanks and kind regards Marcel

Ensure the HDMI cable is attached ok, if that does not work unplug the Apple TV for about 3-5 minutes, plug it back in and re-test.

Unplugged both the TV and the AppleTV and voila it works perfect again.

Strange that the same method didn't work last time. Maybe it wasn't disonnected long enough or something.

Anyway - case solved. Thanks.
