This article covers KOORUI モニター 21.5インチ 100Hz フルhd 非光沢 VAパネル 液晶ディスプレイ Adaptive Sync.

Overview

The KOORUI E2212H is a 21.5-inch VA panel monitor with Full HD (1920×1080) resolution. It supports a 100Hz refresh rate (some listings note 120Hz) and an OD response time of 5ms, making it suitable for everyday PC tasks and light gaming. With sRGB 99% color gamut and a 3000:1 contrast ratio, it delivers vivid and punchy visuals. This monitor features a non-glare (anti-glare) panel that reduces reflections, helping to ease eye strain during long work sessions. It also includes blue-light reduction and flicker-free technology, making it a solid choice for home office or study setups.

Connectivity & Compatibility

The KOORUI E2212H offers two video inputs: HDMI 1.4×1 and VGA×1. The included HDMI cable lets you connect directly to modern PCs and laptops. The VGA port provides backward compatibility with older desktop or notebook computers. However, it lacks DisplayPort and USB-C inputs, so connecting a modern laptop with only USB-C output will require a separate adapter. Also, the monitor does not have built-in speakers, so you will need external speakers or headphones for audio.

Product Info

The KOORUI E2212H is positioned as an entry-level 21.5-inch monitor. Its market price is around the ¥14,000–¥15,000 range, making it an excellent value for first-time buyers or as a secondary display. The warranty covers the panel for 1 year and accessories for 3 years. Included in the box are an HDMI cable, power adapter, and stand, so you can set it up right away.

Best Use Cases

Remote workers and online learners: The 21.5-inch screen and Full HD resolution provide ample space for documents and web browsing. Blue-light reduction and flicker-free technology help reduce eye fatigue during long hours. Budget dual-monitor builders: With its low price, high contrast VA panel, and 100Hz smoothness, this monitor works well as a secondary display alongside a main monitor. VESA mount (75×75mm) compatibility allows for arm mounting to save desk space. * Casual gamers: The 100Hz refresh rate offers noticeably smoother motion than standard 60Hz monitors for fast-paced genres like FPS or racing games. However, competitive esports players may want a faster panel with lower response times.
