This was happening in tandem with another glitch. Occasionally when I’m watching YouTube, there’s a line of pixels that get stuck... that’s the least of my problems. I’m trying to watch Avengers Endgame on Disney Plus and when it goes to play the movie; the movie plays but it’s this weird Jackson Pollock looking mess on the screen. Rainbow dots in 4K map the shapes of what’s supposed to be in color, the sky is black and it’s one big mess. I figured it’s Dolby vision because it gives me problem on the stock Dolby Vision app the tv came with too doing the exact same thing. Please help!!!
