The matte screen surface helps cut down on reflections, and the size is well-balanced for immersive gaming without overwhelming your desk.

The price might be higher compared to traditional LCD monitors, and despite the burn-in prevention features, OLED screens still require some care to avoid long-term image retention. This monitor is ideal for gamers who want the best image quality and speed in one package and are willing to invest in advanced technology while practicing cautious maintenance.
