I had an LG OLED TV for about 9 months, it was a beautiful picture but it gave me 2 different burn ins - 1 from a channel logo and 1 from a news channels bottom scrolling news bar & logo. I get that they are not meant for the average user, but I don't know how OLED can be used for a PC monitor with so many images on the screen that are static for long periods of time (taskbar, desktop icons, browser window, etc)
I had two LG OLED's. A 55" curved and a 65" flat. Both developed burn in by tickers on the bottom of the screen. The 65" was noticeable on anything, but the 55" only on dark solid colors. Although nothing I have owned comes close to the pictures, I wouldn't buy again. I'd imagine a PC is going to be brutal for burn in too. Wish you all luck.
