This article covers LG フレームレス モニター ディスプレイ 27MP400-B 27インチ.

Overview

The LG 27MP400-B is a 27-inch Full HD (1920×1080) IPS monitor with a matte finish that reduces reflections. Its frameless design helps you focus on the screen, and the wide viewing angles (178°/178°) keep colors consistent from almost any position. Positioned as an entry-level model, it covers everyday office work, media consumption, and light gaming without breaking the bank. With a 75Hz refresh rate and AMD FreeSync support, the monitor delivers smoother motion than standard 60Hz panels. Flicker Safe and Blue Light Reduction modes are included to reduce eye strain during long sessions. These features make it a solid choice for users who want a reliable, budget-friendly monitor for mixed use.

Connectivity & Compatibility

The 27MP400-B offers two video inputs: HDMI and D-Sub (VGA). The HDMI port works with modern PCs, laptops, and game consoles, while the D-Sub port ensures compatibility with older hardware. There is no DisplayPort or USB-C, so if you need those, you'll have to use adapters or look elsewhere. FreeSync works over HDMI, though the effective range may be limited. For the best experience with variable refresh rate, check your graphics card's FreeSync support over HDMI. The monitor lacks built-in speakers, so you'll need external speakers or headphones for audio.

Product Info

Released in 2021, the LG 27MP400-B is an entry-level 27-inch monitor that balances price and essential features. It doesn't chase high refresh rates beyond 75Hz or HDR, but it covers the basics well: an IPS panel with good viewing angles, a flicker-free backlight, and a low-blue-light mode. LG backs it with a 3-year warranty and a Zero Dead Pixel Guarantee (also 3 years), which is a nice reassurance for budget buyers. Accessories include a power cable, an HDMI cable, and a quick setup guide. The typical street price in Japan is around ¥16,996 (as of June 2026), making it competitive in the entry-level full-HD monitor segment.

Best Use Cases

Home office and productivity users: The matte IPS panel provides clear text and stable colors for spreadsheets, documents, and video calls. Flicker Safe and blue light filters help reduce eye fatigue during long workdays. However, the color gamut is limited (roughly sRGB coverage, not quantified), so creative professionals needing wide gamut (DCI-P3, Adobe RGB) should consider a higher-tier monitor. Casual gamers: The 75Hz refresh rate and FreeSync support noticeably improve smoothness in fast-paced games like shooters and racers compared to a standard 60Hz monitor. Response time is 5ms (GTG), which is adequate for non-competitive play. Serious eSports players will likely want a 144Hz+ panel with faster response for a competitive edge. * Second monitor or first monitor for less tech-savvy users: The simple setup and included HDMI cable make it easy to get started. The frameless bezel works well in multi-monitor setups. The 3-year warranty and dead pixel policy add peace of mind. The stand offers only tilt adjustment (no height, pivot, or swivel), so you may need a VESA monitor arm (100×100mm compatible) for ergonomic positioning.
