ASUS ROG Strix XG27UCG-W 4K Gaming Monitor: dual mode 160Hz / 320Hz

The ASUS ROG Strix XG27UCG-W is a 27-inch gaming monitor in white. Its main feature is dual mode: it can run at 4K resolution (3840 x 2160) at up to 160Hz, or switch to Full HD (1920 x 1080) at up to 320Hz. That lets one screen suit both detailed single-player games and fast competitive shooters. Here is what the specifications mean.

Dual mode: 4K or Full HD

A 4K picture shows far more detail than Full HD, but it asks much more of a graphics card. Many competitive players prefer very high frame rates over sharpness. ASUS's Frame Rate Boost lets you switch to a 1080p 320Hz mode with a hotkey. This helps because rendering fewer pixels typically lets a graphics card produce more frames per second. In 4K mode, you need strong graphics hardware to approach 160 frames per second in demanding games.

Fast IPS and 1ms response

ASUS Fast IPS technology enables a 1ms response time (grey to grey). Response time describes how quickly pixels change colour, and a lower figure typically means less visible smearing behind moving objects. IPS panels are also generally known for wide viewing angles and solid colour. Note that 1ms GTG is the brand's rated figure and real results depend on settings.

ELMB Sync and G-SYNC Compatible

Extreme Low Motion Blur Sync (ELMB SYNC) lets ASUS's motion blur reduction work alongside variable refresh rate. According to ASUS, this eliminates ghosting and tearing. The title also lists G-SYNC Compatible, which means the monitor can work with variable refresh rate on supported NVIDIA graphics cards. Check your own graphics card and cable for the exact requirements.

Colour

The panel covers 95% of the DCI-P3 colour gamut, according to ASUS, with advanced grey-scale tracking for smoother colour gradation and uniformity. DCI-P3 is a wide colour space used in cinema, so a high coverage figure means richer colours in compatible content. The listing's title also mentions HDR.

Connectivity and software

The description highlights a USB Type-C connection, which can carry video from compatible laptops and consoles. DisplayWidget Center is a utility that lets you change monitor settings with a mouse instead of using the on-screen buttons. The listing also mentions AI gaming features; check ASUS's site for what these do.

Size

The monitor measures about 8.6 x 24.2 x 20.1 inches (roughly 22 x 61 x 51 cm) with its stand and weighs 14.6 lb (about 6.6 kg). The listing mentions a three-year warranty.

Who it suits

It suits PC gamers who want one monitor for both visually rich games and competitive play, and who have a graphics card that can drive 4K. It is less useful if you only play at lower resolutions.

What to check before you buy

• Graphics card: check that it can output 4K at the refresh rate you want, and the right cable and port.
• Port versions: confirm which DisplayPort or HDMI version delivers 4K at 160Hz.
• Console use: check the manual for the resolution and refresh rate your console can use.
• Desk space: the stand needs room for a 27-inch screen of this depth.
• Adaptive-sync: check driver settings for G-SYNC Compatible operation.
