A 240Hz refresh rate allows motion to appear exceptionally smooth. Fast-paced titles such as Call of Duty, Valorant, Counter-Strike, Apex Legends, and Fortnite benefit tremendously from the increased fluidity and responsiveness.
0.03ms Response Time
The monitor’s near-instantaneous 0.03ms response time minimizes ghosting and motion blur. This provides clearer visual tracking during rapid movements and intense gameplay scenarios.
OLED Technology
OLED remains the gold standard for gaming image quality. Individual pixel illumination allows true black levels, infinite contrast, and exceptional color accuracy.
HDR True Black Support
HDR content looks significantly more realistic thanks to deep shadows and bright highlights. Games with HDR implementation showcase stunning visual depth and realism.
G-SYNC and FreeSync Premium Pro
Support for both NVIDIA G-SYNC and AMD FreeSync Premium Pro helps eliminate screen tearing and reduce stuttering across various gaming systems.
Modern Connectivity
HDMI 2.1, DisplayPort 1.4, and USB-C connectivity make this monitor highly versatile for gaming PCs, laptops, and current-generation consoles.
Gaming Performance
Gaming is where the LG UltraGear 39GX900A-B truly shines. The combination of OLED technology and 240Hz refresh capability creates an experience that feels significantly more responsive than traditional IPS or VA monitors.
