The LG UltraGear 27GX790B-B redefines esports performance. Engineered for professional competitive gamers who demand both extreme frame rates and perfect image quality, this 27-inch 4th Generation OLED monitor offers Dual-Mode refresh rate switching. Whether tracking targets in tactical shooters at 720Hz or enjoying high-resolution 540Hz QHD visuals, the 27GX790B-B provides an overwhelming competitive advantage.
Performance / Technology Featuring UL Verified Perfect Black and Perfect Color, the 27GX790B-B covers 98.5% of the DCI-P3 color space. Its micro-texture anti-glare low-reflection (AGLR) screen coating preserves vibrant color and deep blacks while minimizing distraction from ambient room lighting.
Design & Ergonomics Built around a virtually borderless, ultra-thin 27-inch chassis, the ergonomic stand supports full height adjustment, tilt, swivel, and bidirectional pivot (portrait mode). A 4-pole headset jack supports game audio and microphone communications through a single cable via DTS Headphone:X processing.
Compatibility / Use Cases Designed for esports competitors, FPS pros, and high-end gaming stations powered by modern flagship GPUs (such as NVIDIA GeForce RTX 40 and 50 series). Fully compatible with PC gaming rigs and high-refresh consoles.
Why This Product Stands Out The LG UltraGear 27GX790B-B combines 4th Gen OLED picture quality, Dual-Mode 540Hz/720Hz refresh rates, 0.02ms response time, and DisplayPort 2.1 bandwidth into a single monitor, setting a new benchmark for competitive display technology.
