Hence, if the whole bottom of the screen is a fairly uniform colour, the line won't be noticable, but I think it's probably there all the time. as you can see from the two images posted by OP (and consistent with my experience), the colour of the line at the bottom of the content matches the colour of the bottom right corner of the screen.I'm suffering the same on my 55C9 - the two titles I can remember in which it happens consistently are Bad Boys (the first one) and 24 Hour Party People. I am using 4k Dolby Vision with both the match framerate and the match dynamic range options set to on.Ĭan anyone tell me how I go about raising this issue with Apple support? I wonder if there are other users out there that noticed this - but make no mistake, the room has to be entirely dark and it has to be an OLED TV. After ruling out all hardware components as being the root cause of the issue, the only thing left is software - I am assuming that this is a software bug on AppleTV OS. I used a different HDMI port to rule out HDMI port issues on my AVR - same issue. Same issue! I replaced all connected HDMI cables with certified HDMI 2.1 cables from Oehlbach - same issue, but only on AppleTV. I have replaced my Gen2 AppleTV from 2021 with the Gen3 AppleTV from 2022.
However, to rule out that my AV Receiver (Denon AVC-X4700H) is not the source of the issue, I used my UHD Player (DP-UB9004) to play the same YouTube video - again, no white spots on the screen, all perfectly black (as it should be). I have played the same YouTube video from the YouTube App that is available from the Sony TV directly - no white spots. See picture below to understand how it looks like in an entirely dark room when playing any of the "black screen" videos from YouTube. However, I have done extensive testing to rule out all other hardware components as being the source of the issue. I am not sure if this issue was from the very beginning, because it is not easy to notice at first when watching regular content. When playing a YouTube video that displays a black screen, I can see static white noise / spots on my Sony Bravia XR-77A80K (OLED from 2022).
