Overview

LG's UltraGear OLED 27GX700A-B is a 26.5-inch gaming monitor built around the fourth-generation Primary RGB Tandem OLED panel. It delivers a WQHD (2560x1440) resolution, a 280Hz refresh rate, and a 0.03ms response time, making it equally capable for competitive shooters and visually rich AAA titles. With a peak brightness of 1500 cd/m² (at 1.5% APL), DCI-P3 99.5% color coverage, and DisplayHDR True Black 500 certification, this monitor combines OLED's signature deep blacks with impressive luminance and color accuracy.

Connectivity & Compatibility

Video inputs include DisplayPort 1.4 (with DSC), HDMI 2.1, and a USB-C port supporting DisplayPort Alt Mode and up to 65W power delivery. This setup covers modern gaming PCs, laptops, and consoles like the PS5 and Xbox Series X, allowing VRR and high-refresh-rate output over HDMI 2.1. The included stand offers height, tilt, and pivot adjustments, and the VESA 100x100 mount pattern lets you swap to a monitor arm if desk space is tight. The USB-C upstream port also connects to two downstream USB 3.0 ports for convenient peripheral hookup.

Product Info

Released in April 2026, the 27GX700A-B sits firmly in the high-end segment of the gaming monitor market. Its fourth-gen OLED panel uses a tandem RGB structure to boost brightness and color purity while cutting power consumption by over 20% compared to the previous generation. The street price hovers around ¥77,480 (about $520 USD), which is competitive for a premium 26.5-inch QHD OLED with this feature set. The standard warranty is one year, extendable to four years with LG product registration. In the box you'll find the monitor, stand, power cable, DisplayPort cable, USB-C cable, and a quick-start guide.

Best Use Cases

Competitive gamers will appreciate the 280Hz refresh and 0.03ms gray-to-gray response for buttery-smooth motion and minimal input lag in fast-paced titles like Valorant or Call of Duty. For single-player enthusiasts and RPG fans, the OLED panel's infinite contrast and vivid colors create an immersive experience in games like Cyberpunk 2077 or Final Fantasy XIV (which this monitor is officially recommended for). Creative professionals who work with HDR video or high-gamut photo editing can also benefit from the DCI-P3 99.5% coverage, though the lack of hardware calibration support may be a limitation for color-critical workflows.
