LG 27U631A-B 27 Inch 2K QHD 100Hz IPS Panel 99% SRGB 5MS Dynamic Action Sync Gaming Monitor

The LG 27U631A-B is a 27-inch QHD gaming monitor designed to deliver sharp, colour-accurate visuals for gamers and creative users alike. Built around an IPS panel, it renders a native resolution of 2560×1440 pixels — commonly called 2K or QHD — across a 16:9 aspect ratio with a pixel pitch of 0.2331 × 0.2331 mm, producing fine detail that makes both game environments and productivity work noticeably crisper than a comparable Full HD display. The panel runs at a maximum refresh rate of 100Hz, a step up from the standard 60Hz found in many entry-level monitors. Paired with a 5ms GtG response time (measured at the Faster preset), motion rendering stays clean during fast-paced gaming sequences. LG's Dynamic Action Sync feature minimises input lag so screen action tracks closely with controller or mouse input — useful in competitive and action titles. Color reproduction is a highlight of this model. The display covers 99% of the sRGB colour space (CIE1931, typical), with a guaranteed minimum of 95% sRGB, ensuring that games, photos, and video content appear vivid and true to their intended palette. HDR10 support further extends perceived contrast in compatible content. Typical brightness is rated at 250 cd/m², with a minimum of 200 cd/m², and the IPS panel delivers 178-degree viewing angles horizontally and vertically, so colour and contrast remain consistent when viewed off-centre. Connectivity is practical rather than extensive: a single HDMI 1 port handles standard display connections, while a USB Type-C port supports both video input and up to 15W of power delivery — enough to keep a laptop or tablet topped up from a single cable. A 3-pole headphone output rounds out the audio side. The monitor ships with one HDMI cable included. The stand supports tilt adjustment only; height, pivot, and swivel are not available. VESA 100×100 mm wall-mount compatibility provides an alternative to the included stand. LG's Reader Mode reduces blue-light emission to ease extended viewing sessions, and the virtually borderless three-side design keeps desk aesthetics clean.
