First I would make sure the brightness isn't too high, and then I would consider if the problem is text on screen. The LG OLED panels have WRGB pixel layout, so it doesn't work quite right with the likes of ClearType on Windows. Instead I use MacType on my PC with a modified profile and 117% zoom in windows, and now it's fine to me (the font was an issue when I first got my OLED).
