LG 22U401A-B 22" Full HD VA Monitor - 100Hz, HDR10

The LG 22U401A-B 22" Full HD VA Monitor is a compact 21.5-inch display suited to home office workers, students and casual gamers who need a capable everyday screen without a large footprint. It delivers 1920×1080 resolution on a VA panel with a 100 Hz refresh rate, HDR10 support, and a 99% sRGB colour gamut, making it a practical choice for productivity, content consumption and light gaming in one.

• 100 Hz refresh rate for smoother motion — A 100 Hz refresh rate reduces judder and motion blur compared with standard 60 Hz panels, giving a noticeably smoother experience in games and fast-moving video.
• 1ms MBR cuts blur and ghosting in games — Motion Blur Reduction technology targets ghosting around fast-moving objects, which can give gamers a clearer view during action-heavy sequences.
• VA panel with 3000:1 contrast ratio — The VA panel achieves a 3000:1 contrast ratio, producing deeper blacks and more defined shadow detail than typical IPS alternatives at this size.
• 99% sRGB coverage and HDR10 support — With 99% sRGB (Typ.) colour gamut coverage and HDR10 compatibility, it reproduces a wide range of colours accurately for creative work and vibrant gaming visuals.
• Flicker Safe and Reader Mode for long sessions — Flicker Safe technology reduces screen flicker, and Reader Mode adjusts the colour tone to ease eye strain during extended reading or document work.
• VESA-compatible with wide voltage support — The 100×100 mm VESA mount lets it pair with a third-party arm or wall bracket, and the 100–240 V power input makes it usable internationally.

• ✓ Connects to any PC or laptop with an HDMI output — supports up to 1920×1080 at 100 Hz over HDMI.
• ✓ Connects to older desktops via VGA (D-Sub) — maximum resolution over VGA is 1920×1080 at 75 Hz.
• ✓ Mounts on any VESA 100×100 mm compatible arm, stand or wall bracket (bracket sold separately).
• Note: The recommended operating resolution is 1920×1080 at 60 Hz; 100 Hz is available over HDMI depending on the connected PC's graphics output capabilities.
• ✗ No DisplayPort input — users whose PC or laptop outputs only DisplayPort will need an active adapter.
• ✗ No USB-C input — devices that output video only via USB-C will require an adapter to HDMI or VGA.

Best for:

• Home office and productivity users who want a compact 21.5-inch Full HD screen with a comfortable 100–240 V power range and LG Switch multi-window support.
• Casual and budget-conscious gamers who benefit from 100 Hz refresh, 1ms MBR and Black Stabiliser without needing adaptive sync technology.
• Content creators working in sRGB who need accurate colour reproduction — 99% sRGB (Typ.) coverage suits photo editing and graphic work within the standard colour space.
• Users with limited desk space — at 2.3 kg and 49.3 cm wide, it fits comfortably in compact setups, and VESA compatibility allows arm mounting to free up desk surface.
• Long-session readers and students who benefit from Flicker Safe and Reader Mode to reduce eye fatigue during extended use.

Trade-offs:

• Competitive gamers who need adaptive sync — this monitor does not support AMD FreeSync or NVIDIA G-SYNC, so screen tearing can occur when frame rates fluctuate.
• Users who need height or pivot adjustment — the stand only tilts between -5° and 20°; there is no height adjustment, swivel or portrait pivot.
• Those who require built-in speakers — there are no integrated speakers; audio output is headphone-only.
• Anyone needing a USB hub at the monitor — there is no built-in USB hub, so peripherals must connect directly to the PC.
• Wide colour gamut or professional colour work beyond sRGB — the panel covers sRGB at 99% (Typ.) but there is no stated DCI-P3 or Adobe RGB coverage figure in the specifications.
