Just delays it. Such burn in does take a lot of time plus the user/owner has to put up test patterns to try to reveal it. That sort of owner can find burn on LCDs which are extremely tough to leave a mark on.
Screen shift is a good thing. Use it.
Watched an article on You Tube about LG OLED screens were easy to get an image burned or displayed ; after a channel has been watched an extended length of time. Such as a channel name or Id in lower right corner of the screen. I read on the online owners manual something about turning on screen shift, would that prevent this problem?
