This article covers LG ゲーミングモニター UltraGear 27GP950-B 27インチ.

Overview

LG's UltraGear 27GP950-B is a 27-inch 4K Nano IPS gaming monitor that has set a benchmark for high-refresh 4K displays since its release. With a native 144Hz refresh rate and 1ms GTG response time, it delivers smooth motion and sharp visuals across fast-paced shooters, open-world RPGs, and competitive titles. The inclusion of two HDMI 2.1 ports is a standout feature, enabling 4K/120Hz output from PlayStation 5 and Xbox Series X without any compromise. The panel also carries DisplayHDR600 certification and covers 98% of the DCI-P3 color space, making it suitable for both gaming and creative work. In the market, this monitor sits firmly in the high-end segment. It was one of the first 27-inch 4K monitors to offer full HDMI 2.1 support, and it remains a strong competitor against newer models like the ASUS ROG Swift PG27UQ. The Nano IPS technology provides a winning balance of fast pixel response and wide color gamut, appealing to enthusiasts who demand the best image quality without sacrificing responsiveness.

Connectivity & Compatibility

On the rear panel, you'll find two HDMI 2.1 ports (capable of 4K/120Hz), one DisplayPort 1.4 (with DSC for 4K/144Hz), and two USB 3.0 Type-A downstream ports plus one USB 3.0 Type-B upstream port. This layout allows you to connect a PC and two consoles simultaneously, switching between them via the monitor's joystick control. The monitor supports both NVIDIA G-Sync Compatible and AMD FreeSync Premium Pro, ensuring tear-free gameplay with compatible GPUs from both camps. For physical mounting, the 27GP950-B uses a standard VESA 100×100mm pattern. The included stand offers height adjustment (up to 110mm), pivot (90° rotation), and tilt (-5° to 15°), giving you flexibility to set up your desk ergonomically. It also supports VESA arm or wall-mount installation for cleaner cable management.

Product Info

Released in June 2021, the 27GP950-B originally carried a launch price around ¥100,000, but as of mid-2026 you can find it on Japan for approximately ¥79,800. LG backs it with a 3-year warranty that includes a zero-bright-dot policy: if any bright pixel appears within the warranty period, LG will repair or replace the unit free of charge. In the box you get the monitor panel, stand base, power cable, DisplayPort cable, USB cable, and a quick setup guide. Market positioning is clearly high-end. The combination of 4K resolution, 144Hz refresh rate, and HDMI 2.1 connectivity is still rare at this price point, and the Nano IPS panel's color accuracy gives it an edge over many VA-based competitors. However, driving this monitor to its full potential requires a powerful GPU—at least an RTX 3080 or equivalent—so budget for a high-end system accordingly.

Best Use Cases

Enthusiast PC Gamers – If you own a GeForce RTX 4080 Super or Radeon RX 7900 XTX, this monitor will let you experience 4K gaming at 144Hz with HDR and variable refresh rate. The 1ms response time is particularly beneficial in competitive shooters like Call of Duty or Overwatch. Console Gamers (PS5 / Xbox Series X) – The HDMI 2.1 ports are a rare find in 27-inch monitors. You can play supported titles at 4K/120Hz without any downscaling, and FreeSync Premium Pro works with Xbox Series X for smooth gameplay. Dual-Use Creators/Gamers – The 98% DCI-P3 coverage makes color-critical work possible on the same display you game on. If you edit videos or photos and still want a high-refresh gaming experience, this monitor eliminates the need for a secondary screen. Who Should Skip It – Competitive esports players who prioritize 240Hz or higher at 1080p should look at dedicated fast TN or IPS panels instead. Also, if your GPU lacks DisplayPort 1.4 with DSC support, you won't be able to achieve 4K/144Hz, making the investment less worthwhile.
