My PC was the first to do this when it woke from sleep mode after getting an RTX 2070 Super. Got a PS5 and it's doing the same when I turn it on. It happens when I start the PS5 before the TV (and the PS5 turns the TV on). I haven't seen it if I do the reverse. I get a black screen with green lines and not the actual image I should get. Getting the TV to leave the input and come back restores the image. Is the TV or one or more connected systems at fault?
