LG 27U631A-B 27 Inch Monitor

The LG 27U631A-B is a 27-inch (68.58 cm) QHD monitor designed for professionals, creatives, and everyday users who demand colour accuracy and fluid performance without sacrificing desk space. At its core is an IPS panel that produces wide 178-degree viewing angles both horizontally and vertically, meaning colours and contrast remain consistent whether you are looking straight on or from the side. The 2560 x 1440 resolution delivers noticeably more detail than a standard Full HD screen, making it well-suited for editing documents, spreadsheets, photos, and video content at the same time. A 100Hz maximum refresh rate keeps motion smooth during fast-scrolling workflows and casual gameplay, while a 5ms GtG response time at the Faster setting reduces visible ghosting. Dynamic Action Sync further minimises input lag so screen reactions feel responsive. Colour fidelity is a highlight: the display covers 99% of the sRGB spectrum (CIE1931, typical) and was colour-calibrated at the factory. HDR10 support adds tonal range to compatible content, and the HDR Effect mode applies local tone-mapping when native HDR is unavailable. Black Stabilizer makes shadow detail more visible in darker scenes, while Super Resolution+ sharpens lower-resolution content when it is upscaled. Connectivity is handled by a single HDMI port and a USB-C port that carries both the video signal and up to 15W of power delivery — enough to charge or power many thin-and-light laptops with a single cable. A 3-pole headphone output lets you connect headphones or powered speakers directly. Comfort features include Reader Mode, which adjusts colour temperature and luminance to reduce eye fatigue during long reading sessions, and Flicker Safe technology that eliminates invisible panel flicker. The slim three-sided bezel keeps the visual footprint minimal, and the tilt-adjustable stand lets you find a comfortable viewing position without requiring additional hardware. Smart Energy Saving and an Auto Input Switch round out the feature set.
