This article covers ASUS 4K ゲーミングモニター ROG Strix XG27UCG-W デュアルモード 白 27インチ.

Overview

The ASUS ROG Strix XG27UCG-W is a 27-inch 4K gaming monitor with a unique dual-mode feature that lets you switch between 4K at 160Hz and Full HD at 320Hz. It uses a Fast IPS panel with a 1ms GTG response time, making it suitable for both high-resolution content and competitive gaming. Available in a white finish, it brings the ROG Strix styling to life while offering practical connectivity like USB-C with 15W power delivery, a fully adjustable stand, and VESA mount compatibility. This monitor is positioned as a mid-to-high-end option for gamers who want versatility.

Connectivity & Compatibility

Input options include one DisplayPort 1.4 (HBR3), one HDMI 2.1, and one USB-C with DP Alt Mode and 15W power delivery. A 3.5mm audio jack is also present for direct headphone connection. The stand offers 120mm height adjustment, -5°/+20° tilt, ±45° swivel, and ±90° pivot. VESA 100×100mm holes are included for arm mounting. HDR support is standard, with a typical brightness of 350 cd/m². Compatibility with modern GPUs is excellent: HDMI 2.1 supports full 4K 120Hz on consoles, and DisplayPort 1.4 handles the 4K 160Hz signal smoothly.

Product Info

Launched in 2024, the XG27UCG-W currently retails around ￥71,636 on Japan. ASUS provides a 3-year warranty for the Japanese domestic model. Accessories include DisplayPort and HDMI cables, a power cord, quick-start guide, ROG pouch, and a warranty card. The pouch holds the included smartphone holder that clips onto the monitor’s top bezel. Market-wise, this monitor sits between mid-range and high-end. Its dual-mode capability is a rare differentiator among 27-inch 4K gaming monitors, justifying the premium over simpler 4K 144Hz models.

Best Use Cases

Competitive FPS gamers: The 320Hz mode at 1080p delivers buttery-smooth motion with minimal input lag. The 1ms GTG response keeps ghosting at bay. However, if you only play single-player titles, a cheaper 4K 144Hz monitor might be a better value. Versatile users: Professionals can enjoy 4K desktop real estate during the day and switch to high refresh rate gaming at night. USB-C makes it convenient for laptop docking, though the 15W PD is insufficient for power-hungry laptops. Style-conscious builders: The white chassis and Aura Sync lighting match white-themed PC builds perfectly. The smartphone holder is a nice bonus for streamers. But be aware that white surfaces show dust and smudges more easily. Not ideal for color-critical work: Without official color gamut coverage figures, photo and video editors should look at dedicated professional monitors with factory calibration.
