For a bright room they only now have(ish!) the juice to actually perform*, but they all recommend to run them are like 80% brightness.
*top, expensive models I mean, and even tho for a lot of content you need a little bit less brightness compared to even VA, due to contrast, but that is way not enough to make a difference + with dimness of OLEDs you have to be extra careful to buy one that actually has a black screen when turned off in a bright room (and not grey in a bright environment bcs it fucks the contrast).
So, my use case, with running at 100% brightness, I would have some sort of burn-in in a few years. Absolutely not something I want to look at for a decade.
And I’m old enough to have had beautiful PVA & MVA matrices that burned in (I bought them old actually -I clinged to my CRT for as long as possible, and then suffered TN for gaming- and for my second monitor most of the time).
One of my 1600×1200 PVAs (the later model without burn in) is still next to my serves, so every few years or so it shows console :‘’'(.
As I see it, for a bright room, there are no OLEDs … maybe some of the newest gen TVs maybe?
For a normal room, buy an OLED with the mentality that you might want to e-waste it after 5 years of taking care of it (no static content, no max brightness).
(This is way batter than 1 or 2 years from a few gens back.)
Probably all of them have it, I would be surprised if you could turn it off actually.
The “refresh” just makes the pic more uniform again, the refresh itself is a sort of controlled burn-in.
Not too long ago OLEDs would lose brightness due to it (especially red brightness iirc?).
