I have an LG OLED TV, and I would recommend against purchasing an OLED for monitor use.
Burn-in is still a huge issue. I've used mine for about a year and the red channel is full of distracting burn-in patterns from still elements on my screen from things like wallpapers, tiled window borders, taskbar/docks, HUDs from games, etc.
Does anyone know if MicroLEDs could suffer from burn-in as well? I.e. do they also degrade over time based on usage?
