Heat management is thoughtfully designed to reduce the chance of OLED burn-in, a common concern with this panel type. Connectivity includes DisplayPort, HDMI, and USB 3.0, covering most gaming setups. OLED monitors tend to be pricier, and despite added protections, burn-in can still be a risk with static images over long periods. The size and matte surface make it comfortable for extended gaming sessions.
