Asus ROG Strix XG27ACMES 27 Inch Gaming Monitor

The ASUS ROG Strix XG27ACMES is a 27-inch WQHD gaming monitor engineered for competitive and enthusiast gamers who demand both speed and visual fidelity. Driven by ASUS Fast IPS panel technology, it renders every frame at a crisp 2560×1440 resolution across a wide 178°/178° viewing angle, so colours stay consistent whether you are sitting directly in front or watching from the side. At the heart of its performance is a 255Hz overclocked refresh rate paired with a 0.3ms minimum grey-to-grey response time. This combination keeps motion sharp during the most frantic first-person shooter or racing game sequences. ASUS Extreme Low Motion Blur Sync (ELMB Sync) works simultaneously with variable refresh rate, eradicating ghosting and screen tear in a single pass. G-Sync compatibility and FreeSync Premium support mean the monitor can adapt to fluctuating GPU frame rates on both major graphics platforms. Colour coverage is measured at DCI-P3 97% and sRGB 133%, and each unit passes factory colour-accuracy checks before shipping. Display HDR400 support with a 400 cd/m² peak brightness and 1300:1 contrast ratio deliver noticeably deeper shadows and brighter highlights compared to SDR-only panels. The 10-bit colour depth (1073.7 million colours) further enhances gradient smoothness. AI-powered ROG Gaming AI features include a Dynamic Crosshair that analyses the screen scene in real time, and Dynamic Shadow Boost, which brightens dark areas without clipping bright zones — a tangible advantage in low-light in-game environments. GamePlus and GameVisual modes offer additional scene-optimisation presets. Connectivity is handled by DisplayPort 1.4, an HDMI port, and a USB Type-C port with DisplayPort Alt Mode and power delivery — keeping desks tidy and reducing cable clutter. The ergonomic stand supports tilt (+20° to −5°), swivel (±45°), pivot (±90°), and height adjustment (0–110 mm). VESA 100×100 mm mounting, a 1/4″ tripod socket, and Kensington lock slot round out the physical feature set. No built-in speakers are included.
