LG 22U401A-B 21.5" Full HD 100Hz VA Monitor — 99% sRGB | HDR10 | 1ms MBR | Black

The LG 22U401A-B is built for home users, students, and everyday office professionals who need a compact, reliable, and smooth 21.5-inch Full HD monitor for daily productivity, web browsing, document work, video streaming, and light gaming at an accessible price. It is well-suited for home desks, student setups, small office workstations, and secondary monitor configurations where vivid VA panel colours, a 100Hz refresh rate, gaming-oriented features, and an organised L-shaped stand base are the priorities.

The 22U401A-B features a 21.5-inch VA panel with a native 3000:1 contrast ratio — significantly higher than standard IPS panels — delivering deeper blacks and more vivid contrast for an immersive viewing experience across movies, content, and games. The 99% sRGB colour gamut produces accurate, vibrant colours suited for everyday content consumption and light creative work. At 100Hz with 5ms GtG response time and 1ms Motion Blur Reduction (MBR) mode, it provides smooth, clear motion rendering for casual gaming and fast-scrolling content — with MBR specifically designed to minimise blur and ghosting during fast-paced gameplay. Dynamic Action Sync reduces input lag for near-real-time responsiveness in gaming scenarios. Black Stabilizer brightens dark scenes to help identify low-light details without overexposing bright areas — useful in darker game environments. Reader Mode adjusts colour temperature and luminance for eye-comfortable text reading during extended sessions, while Flicker Safe reduces screen flicker across brightness levels. Variable Refresh Rate (VRR) support helps reduce screen tearing when paired with compatible graphics hardware. LG Switch app enables quick screen division and display mode switching directly from the desktop. The L-shaped stand with a square base keeps the desk organised and supports -5° to +20° tilt for comfortable viewing adjustment. VESA 100×100mm mounting enables arm or wall-mount deployment. Made in India by LG Electronics.
