    This review is about the size: 32 "

    No matter what anyone says, once you go OLED you don't go back to any other type of display. This is the second one I've bought; the previous one was also a Samsung OLED G8, but it was an ultrawide 34" and I wanted a more immersive screen for first-person games. After 1200 hours of use, the previous one showed no trace of burn-in, and I hope this one will be the same.
