LG UltraFine 27″ QHD IPS 100Hz USB-C Monitor – 27U631A-B

The LG 27U631A-B sits in the UltraFine series as a balanced QHD productivity monitor with enough speed for casual gaming. Its 27-inch QHD (2560×1440) IPS panel delivers sharp pixel density, wide viewing angles, and 99% sRGB colour accuracy for document editing, photo review, and video work.

A USB-C input with 15W power delivery simplifies single-cable laptop connections for light office setups, while HDMI provides a secondary source input. The 100Hz refresh rate and 5ms GtG response time deliver smooth enough performance for everyday gaming and video content beyond basic 60Hz. HDR10 adds depth to compatible media. LG’s Reader Mode reduces blue light for comfortable all-day screen use, and Dynamic Action Sync reduces input lag for any gaming sessions. The three-side borderless design keeps desk clutter minimal. VESA 100×100mm allows arm mounting.
