LG 22U401A-B 21.5-inch FHD Monitor – 100Hz, HDR10

The LG 22U401A-B is a compact 21.5-inch Full HD monitor designed for everyday computing, productivity, entertainment and casual gaming. Its 1920 × 1080 resolution provides clear and detailed visuals, while the VA panel delivers a 3000:1 typical contrast ratio for deeper blacks and defined images.

With a 100Hz refresh rate and 5ms GtG response time at the Faster setting, the monitor provides smoother motion for scrolling, video playback and compatible gaming. The 1ms Motion Blur Reduction feature can further improve motion clarity when enabled, although LG notes that MBR can reduce luminance and affects the availability of certain features.

The monitor supports HDR10 and offers 99% sRGB coverage, helping deliver a wider and more vivid range of colors. With 250 nits typical brightness and 178° viewing angles, it provides comfortable viewing from different positions.

For gaming, features such as Dynamic Action Sync, Black Stabilizer, Crosshair and VRR help improve responsiveness and visibility during gameplay. The monitor also includes Reader Mode and Flicker Safe for a more comfortable viewing experience during extended reading and work sessions.

The LG Switch app adds convenient productivity functions, including the ability to divide the display into up to six sections and access mapped functions through customizable controls. The monitor also features a 3-side virtually borderless design and an L-shaped stand with -5° to 20° tilt adjustment.

Connectivity includes one HDMI port, one D-Sub/VGA port and a headphone output, while 100 × 100mm VESA support allows wall or monitor-arm installation with compatible mounting hardware.
