Here to comment again on burn in, 2017 LG B7A 4k OLED DOLBY VISION and CINEMA/ HDR purchased 2 weeks before black friday last year, in 2017.
Only use it for ps4 gaming, for netflix and hulu and youtube apps on the smart tv, and for blu rays. Once in a while i leave netflix stationary or the movie paused, but when i return a few minutes later. the safety options have kicked in.
- Exploding dots screensaver, different colored dots exploding on black background that looks turned off.
- Dim screen during game sessions
- the screen shift and pixel shift option is turned on, just in case.
Even with these safety features, I have left games stationary in menu like the RDR2 map or the RDR2 pause screen for over 15-20 minutes. And it has been perfect for a year so far. I think the issue comes when you leave the netflix or game paused with none of the safety options for like a day straight. Like leaving it for 12 hours in a row for 7 days a week maybe... That or leaving the desktop turned on with icons on the tv (which i recommend to never use an oled as a desktop or PC monitor..) When using it strictly to game, stream with the smart tv apps, or play discs... It seems perfect.
Netflix has been left on during movies and all 3 safety options turn on. It has also been left on in the menu but same thing.
I am convinced that ppl seeing burn in are using sets from 2014-2015 that do not have the safety options of the 2017-2018 tvs.
There are other options to turn on as well. Happy gaming folks
