I don't know that I agree with that, monitors last a really long time. Unless you're saying burnin won't happen in say 10 years, but based on a LTT video 2 years back, it absolutely was still happening with the 2020 models. The 2021 and later EVO displays are probably less susceptible though.
Well, yeah, it's 2024 now.
Hopefully people are talking about buying a recent model, not a 3 year pre-owned one.
If we're talking used then that is a different thing.
But seriously look at what IceStorm just posted. 16 hours a day.
That's not normal. Not unless you are thinking of buying an OLED for some kind of lobby display screen or monitoring display that is on 24/7 or whatever. Heck, LCD will look like trash after a couple years of that level of use too, if you have static elements on the screen.
For the average gamer usage, a quick google shows around 1 hour of use a day, and for TV it is around 4 hours a day. Even at that, combined, it is only 5 hours of use a day. Not even half of IceStorm's use.
I would say that 'light' use is more like 2 hours a day at most. At that level, you probably don't even have to modify your habits
at all to keep an OLED in good shape, as long as it is decent quality. For a gamer who gets in a couple hours a day and maybe 4 or so on weekend days, the minimal effort of turning on the wallpaper switcher feature and having the screen run its pixel cleaner function once a month or whatever is probably completely fine.
The TVs actually have automated routines for image retention prevention and to keep everything working happily. You do have to let them run though. As you can see from rtings test, if you run the TV too much every day you can prevent it having a chance to run the maintenance it needs to do.

LG seemed to do pretty well in their test but Sony had some problems on a couple of models, likely because it could not get a chance to run its screen maintenance jobs due to their aggressive usage model (20 hours of use a day).
Assuming the TV/monitor will be used in anything approaching an 'average' usage pattern, it should be fine with minimal changes in habits required. If you feel you are on the outer edge of the bell curve on usage (more than 8-10 hours of display use per day), then yeah, LCD might still be better for you, though those have failures under heavy use as well. Basically, if you want your screen to go through that kind of heavy use, get something with a good warranty and then buy that extended warranty for a few more years coverage.
