I can't bring myself to get an OLED when I know it will get the taskbar and window decorations burned into it after a few years. One day if they invent one with truly zero burn-in I'll consider it.
It will take so long for burn in that you probably want to buy something new anyway.
My LG OLED 4k tv is by far the best picture I ever had.
My Samsung 4k 27" gaming OLED is beautiful when gaming too
I can't imagine how annoying it would be to watch a movie or play a game and see something burnt into the white parts of what I'm supposed to be looking at.
I don't want to be purchasing a new gaming monitor every two years.
