ASUS ROG Strix XG27AQMR 27-inch 300Hz Monitor: features, specs and who it suits

The ASUS ROG Strix XG27AQMR is a 27-inch gaming monitor with a QHD (2560 x 1440) Fast IPS panel and a 300Hz refresh rate. It is aimed at fast-paced games where smooth motion matters, and it adds HDR support and adaptive sync. Below is what each headline spec means and what you need to run it properly.

QHD resolution at 27 inches

QHD, also called 1440p, has about 78 per cent more pixels than Full HD. On a 27-inch screen, it typically gives noticeably sharper text and game detail while asking less of a graphics card than 4K. Many players see 27-inch QHD as a balance between clarity and frame rate.

300Hz and 1ms explained

A 300Hz refresh rate means the screen updates 300 times a second. Higher refresh rates reduce motion blur and make fast movement easier to follow, but the gains shrink as the numbers rise, and your graphics card has to produce a matching frame rate to use them. ASUS also quotes a 1ms response time (GTG, grey-to-grey), the time a pixel takes to change shade. The Fast IPS technology is ASUS's way of getting that speed from an IPS panel, which typically offers wider viewing angles and better colour than TN. ASUS says this comes without compromising image quality.

Adaptive sync and motion clarity

The monitor is G-SYNC Compatible and supports FreeSync Premium Pro. Both let the screen vary its refresh rate to match your graphics card, which helps remove tearing and stutter. ASUS's ELMB SYNC technology enables Extreme Low Motion Blur at the same time as G-SYNC Compatible, which the brand says reduces ghosting and tearing together. Which graphics card features work will depend on your card and drivers.

HDR and colour

The monitor is DisplayHDR 600 compliant and covers the DCI-P3 colour gamut, which ASUS says delivers strong contrast and colour performance. DisplayHDR 600 is a mid-level certification of the VESA standard, with a peak brightness target of 600 nits. Without local dimming zones, HDR on a monitor like this is typically more modest than on a high-end display, so treat it as a boost rather than a cinema-grade image. Check the full specification for detail.

Connections, size and weight

The title lists a DisplayPort input. Check the full specification for HDMI and USB ports. The package measures about 24.2 x 10.4 x 15.7 inches (61 x 26 x 40 cm) and weighs 16.1 lb (about 7.3 kg), which suggests a sturdy stand.

Who it suits

It suits competitive players with a graphics card that can drive high frame rates at 1440p, and people who want a sharper 27-inch screen for gaming and creative work. If your PC can't reach well beyond 144 frames per second in your games, a lower-refresh monitor may serve just as well.

What to check before you buy

• Graphics card: make sure it can output 1440p at high refresh rates with the right ports and cables.
• Cable: use the cable type needed for 300Hz, and check which one is included.
• Desk space: the stand and 27-inch size need room.
• Features: read the manual to learn which combinations of ELMB SYNC, HDR and adaptive sync can run together.
• Mounting and ports: check the full specification for VESA mounting and any extra inputs.

The short version

• A 27-inch, 2560 x 1440 Fast IPS gaming monitor at 300Hz with 1ms GTG response.
• G-SYNC Compatible, FreeSync Premium Pro and ELMB SYNC.
• DisplayHDR 600 with DCI-P3 colour coverage.
• Best matched with a graphics card that can sustain high frame rates.
