LG 27G640A-B Ultragear 27-Inch QHD IPS Gaming Monitor – 300Hz, 1ms, G-Sync, HDR400

Speed meets precision in LG's 27G640A-B Ultragear — a 27-inch QHD IPS gaming monitor designed for competitive play and immersive visuals. The panel combines crisp details with wide viewing angles, helping colors stay accurate whether you’re peeking from the side or leaning into the action.

At the core is speed. A blistering 300Hz refresh rate paired with a 1ms G2G (gray-to-gray) response time helps preserve motion clarity during fast in-game action. While you chase a win, the display can keep up with the pace, delivering smooth transitions and responsive control that can feel instant to the touch.

Vivid visuals with cinematic contrast

Color and contrast are crafted to elevate scenes without exaggeration. The monitor covers up to 95% of the DCI-P3 color gamut and includes VESA DisplayHDR 400, delivering bright highlights and deep shadows that make vivid hues pop and dark moments feel more dimensional.

• Sharp, detailed visuals ideal for shooters and racers
• Vibrant color with strong contrast in bright and dark scenes

To ensure a seamless experience, the LG 27G640A-B supports both NVIDIA G-SYNC Compatible and AMD FreeSync Premium. This helps reduce tearing and stutter across PC and next-gen consoles when VRR is available, contributing to a steady, immersive experience.

In-game tools and practical features

Beyond speed and color, this monitor offers features designed to support real-time decisions in games. Dynamic Action Sync can minimize input lag, Black Stabilizer brightens dark areas for improved visibility, an FPS Counter provides performance feedback, and a Crosshair overlay can assist precision. These tools are designed to support your playstyle without promising specific outcomes.

Connectivity, ergonomics, and versatility

Connectivity is built to handle modern setups. A USB-C port provides 15W power delivery, two HDMI 2.1 ports handle high-bandwidth sources, and DisplayPort 1.4 supports high-refresh content. The stand offers tilt, height, swivel, and pivot adjustments, helping you find a comfortable, ergonomic viewing position. A slim profile and refined bezels keep the focus on the action while maximizing desk space.

Whether you’re chasing victory in fast-paced multiplayer titles or enjoying cinematic single-player adventures, the LG 27G640A-B blends speed, color, and flexibility to support your setup. It presents a compelling option for gamers who value rapid response, vibrant visuals, and adaptable connectivity, all with a design that invites long gaming sessions without asserting guarantees.
