Apple TV 4K Dolby Vision + LG OLED65C7P = Flicker bug

I also have this issue with the LG OLED65B7P. It occurs every couple of minutes no matter what you are doing; while on the home screen, using Netflix, watching Apple Movies, even the screen saver. I use the Belkin Ultra High Speed HDMI cable Apple recommends. I started to suspect it was Dolby Vision but didn't think to turn it off until I saw this post, thanks. I hope it is fixed soon, it is very annoying. For now, I'll just use HDR10.

I have the same set up and my LG is brand new (set it up last week). I started to notice this behavior a couple of days after I set it up. I use the apple tv 4k almost exclusively for my streaming content. Until this thread, I thought it was the beginning stages of the infamous LG tv flicker issue - but it doesnt look like the Youtube videos... It happens so fast I dont know if it is the same ghosting in your pic..but it is closer to what you describe. I will switch over to HDR 10 and test the TrueMotion slider settings to see what happens. I will also see how the display looks on my Amazon FireTV. The Apple TV 4K has been so nice I havent even tested my Amazon TV since hooking up the new LG.

I have this same issue with my LGOLED65B7A. Didn't make the connection that it happened only on Dolby Vision until I saw this thread.

Based on another comment the two sliders for TruMotion are De-Judder (0 by default) and De-Blur (10 by default). Going to run with this for the next few days to see if it fixes the problem, but this should be addressed by an Apple Engineer, no sense that the Apple TV 4k has issues with an out-of-the-box configuration for an LG OLED TV.

Found this thread through some Google searching. I'm having the same exact issue on my LG B7A. Was about to return my Apple TV but will go ahead and keep it. Shame I can't use Dolby Vision for now but glad you figured out that HDR gets rid of the problem. Please give an update if you find a fix and I'll do the same.

EDIT: Didn't see all the replies until I posted this. Trying that de-blur slider method as well. Thanks for the tip!

I have this exact issue. Good cable, LG works great on other inputs but getting flicker in all of the Apple TV 4K interface. I just noticed it while watching a movie and the screen kept changing with a quick flicker. It’s driving me nuts.

Yes, this is happening with my LG OLED55B7A as well! So happy that you posted, I posted a video of it happening on my TV:

I'm not sure but it feels like I don't see it until the Apple TV warms up. I guess we should contact Apple Care...

Turning TruMotion from off to User - 0 seems to work for me as well...

I had a similar problem when connecting my AppleTV 4k to Vizio M65-D0.

The issue was occurring when I was plugged into HDMI 2 and had the Apple TV Setup for Dobly Vision 4K @ 60hz.

The solution was to plug the Apple TV directly into HDMI 1.

I am not sure if the exact tech reasons why this fixed my problem. I assume that it has to do with the fact that the specs on each HDMI port on the display are different.

Now that I am plugged directly into the HDMI 1, I have had zero problems with picture or audio.

Hope this helps someone else out there.

It appears that tvOS 11.2 does not help with the LG OLED Dolby Vision/TruMotion flicker bug. The only option, as previously mentioned, is to set both TruMotion De-Judder and De-Blur sliders to 0. Thanks again for the troubleshooting, this is one annoying bug.

I am having the same issue and also returned my original Apple TV becasue I thought that was bad. I have tried changing cables and no improvement. All of my software is up to date and sadly a month later it’s still not fixed. I was actually wondering if it could be that my TV has an issue with Dolby Vision as this is the only device I own that supports it. I did have a question though, how do you know the built in Netflix app has Dolby Vision? I don’t seem to have that display option in LG tv setting when I am on the app. I can put the picture mode in HDR Effect, but not Dolby Vision.

Same issue with OLED65B7P in Japan. I noticed it stopped when in HDR so avoiding Dolby Vision which ***** cuz the image is definitely better on it. But even in HDR I still have the image flickering once now and then and the sound cuts for a millisecond. The True Motion User settings seemed to have helped a bit more too.

The latest update fixed my flickering problem but, before that I used a hack I saw on reddit that was to go to the true motion settings and select “user”. Then set each value to 0. Also, there is a setting in the Apple TV setting where you can have the TV video setting change automatically to match whatever you are watching. For example, if an iTunes movie is coded with Dolby Vision it will make the TV match, and if it is HDRc it will change it to that for playback. It is a really nifty feature. Hope you get your set working seamlessly.

Great tip! I didn't realise that setting you mentioned existed, very good, thanks! I changed those settings, true motion, HDMI input 3 to 1 AND new cable (which I think was the real problem). All working fine now!! :-)

I have the same exact issue with my LG OLED55B7P and the 4K Apple TV.

This worked for me:

Go to your TruMotion settings

Select User

Set both sliders to zero

This is different than just turning TruMotion off, for some reason.

Forgot to verify that changing from Dolby Vision to HDR 10 did fix the flicker problem...sorry
