LG UltraWide 34U511A-B 34 Inch Monitor

The LG UltraWide 34U511A-B is a 34-inch flat IPS monitor built around a 21:9 aspect ratio that gives you significantly more horizontal screen real estate than a conventional 16:9 Full HD display. With a native WFHD resolution of 2560×1080, it lets you view two document windows side by side, keep a spreadsheet and video call open simultaneously, or follow a reference image while you work — all without switching between applications. The IPS panel delivers consistent, accurate colour from virtually any seat, with 178°/178° horizontal and vertical viewing angles, so colour shifts and contrast degradation stay minimal even when colleagues glance at your screen from the side. Factory colour calibration and 99% sRGB coverage (typical) mean what you see on screen closely matches the intended output, which matters for presentations, photo editing, and design work. The monitor supports VESA DisplayHDR 400, a certification that sets defined thresholds for peak brightness, local dimming behaviour, and colour volume. With a typical brightness of 400 cd/m² (minimum 320 cd/m²), HDR content such as highlight-heavy video or photography renders with improved depth and clarity compared to standard SDR displays. At a 100 Hz refresh rate with a 5 ms GtG response time and 1 ms Motion Blur Reduction (MBR), motion in video playback, scrolling, and casual gaming appears smooth with reduced ghosting. Dynamic Action Sync and Black Stabilizer are additional gaming-adjacent features present on this model. Reader Mode adjusts colour temperature and brightness to reduce eye fatigue during extended document work, while Flicker Safe technology eliminates the invisible screen flicker that can contribute to visual discomfort over long sessions. The three-sided virtually borderless design minimises the visual interruption between the screen edge and the desk, and the L-shaped stand supports tilt adjustment for ergonomic positioning. The stand base is also compatible with a 100×100 VESA wall-mount pattern for users who prefer a monitor arm or fixed wall installation. Connectivity includes both HDMI and DisplayPort inputs. There are no built-in speakers.
