ASUS ROG Strix XG27UCG 27-inch Dual-Mode 4K Gaming Monitor: specs

The ASUS ROG Strix XG27UCG is a 27-inch gaming monitor that can switch between two modes: sharp 4K at 160Hz, or Full HD at 320Hz for maximum speed. That makes it a single screen for both cinematic single-player games and fast competitive ones.

Dual mode: 4K or 320Hz

In its 4K mode (3840 x 2160) the monitor runs at up to 160Hz. In the faster mode it drops to 1920 x 1080 at 320Hz. ASUS calls the hotkey switch Frame Rate Boost, and it is aimed at esports play where frame rate matters more than detail. The idea is that you pick the resolution or the speed depending on the game. Either mode only helps when your graphics card can supply the matching frame rates, and 4K at 160Hz is a heavy load for a PC.

Fast IPS and the 1ms response

The panel uses ASUS Fast IPS technology, with a 1ms grey-to-grey response time. IPS panels typically offer wide viewing angles and consistent colour, and the Fast version is tuned for quicker pixel changes. Manufacturer response times are measured under specific conditions.

ELMB Sync and variable refresh rate

ELMB Sync is ASUS's motion blur reduction technology. ASUS says it works together with variable refresh rate, which eliminates ghosting and tearing in fast scenes. Variable refresh rate lets the monitor match the frames your graphics card is producing, reducing tearing and stutter. The listing also names G-SYNC Compatible.

Colour

ASUS lists a 95% DCI-P3 colour gamut and advanced grey-scale tracking, which it says gives smoother colour gradation and uniformity. DCI-P3 is a wide gamut used in film, so this suggests richer colour than a basic sRGB monitor. The title also mentions HDR support; check the specifications for the HDR certification level.

USB-C, AI features and software

The monitor has a Type-C connection, which can carry video from a compatible laptop or device over one cable. ASUS also mentions AI-powered gaming features and DisplayWidget Center, a utility for adjusting monitor settings with a mouse instead of the on-screen menu buttons. The listing includes a 3-year warranty.

Size and weight

With its stand, the monitor measures about 8.6 x 24.2 x 20.1 inches (22 x 61 x 51 cm) and weighs 14.6 lb (about 6.6 kg).

Who it suits

It suits PC gamers who want 4K for visually rich games and a fast Full HD mode for competitive titles, without owning two monitors.

What to check before you buy

• Graphics card: 4K at 160Hz needs a powerful card; check what your PC can output.
• Cables and ports: high refresh rates at 4K need the right DisplayPort or HDMI standard, so check the manual for which port supports which mode.
• USB-C: confirm your device supports video over USB-C.
• Consoles: check which resolutions and refresh rates your console can use.
• Desk space: check the stand depth and height against your desk.
• Mode switching: learn how the hotkey works in the on-screen menu.
