Overview

The LG 27GP850-B UltraGear is a 27-inch gaming monitor built around LG's Nano IPS display technology, delivering QHD (2560x1440) resolution with a native 165Hz refresh rate that can be overclocked to 180Hz. The Nano IPS panel uses nano-sized particles applied to the LED backlight to absorb excess light wavelengths, resulting in richer, more accurate colors covering 98% of the DCI-P3 color gamut. With a 1ms grey-to-grey response time, the monitor is engineered to reduce ghosting and motion blur during fast-paced gameplay, making it well-suited for competitive gaming scenarios.

Compatibility is a strong suit of the 27GP850-B, as it supports both NVIDIA G-SYNC Compatible and AMD FreeSync Premium adaptive sync technologies, eliminating screen tearing regardless of your graphics card. The monitor features DisplayPort 1.4 and HDMI 2.0 inputs along with two USB 3.0 downstream ports for peripherals. Its ergonomic stand allows height, tilt, and pivot adjustments, while VESA 100x100mm mounting support provides additional flexibility. VESA DisplayHDR 400 certification offers a baseline HDR experience, though the monitor truly shines in SDR mode where its color accuracy and fast pixel response combine to deliver an excellent balance of visual quality and gaming performance.
