27-inch QHD 300Hz Gaming Monitor

The LG UltraGear 27G640A-B is a 27-inch IPS gaming monitor with a 2560 x 1440 resolution and a 300Hz refresh rate. It delivers a 1ms GtG response time and covers 95% of the DCI-P3 colour gamut with VESA DisplayHDR 400 certification. The flat panel offers 400 cd/m² brightness and a 1300:1 contrast ratio for vivid visuals.

Competitive Players Seeking Speed

This monitor suits esports enthusiasts and competitive gamers who need ultra-high refresh rates and low input lag for fast-paced titles. The wide 178° viewing angles and factory colour calibration benefit content creators working in sRGB or DCI-P3 workflows. Users prioritising deep blacks for dark-room media consumption may prefer a VA or OLED panel instead.

Straightforward Setup with Full Ergonomic Adjustment

The included stand provides height, tilt, swivel, and pivot adjustments for quick ergonomic alignment without tools. Connectivity includes two HDMI 2.1 ports, one DisplayPort 1.4, and a USB-C port with 15W power delivery plus two USB 3.0 downstream ports. Ensure your graphics card supports DSC over DisplayPort 1.4 to reach the full 300Hz at QHD resolution.
