ASUS ROG Strix XG27ACG-W 27-inch 1440p 180Hz Monitor: specs explained

The ASUS ROG Strix XG27ACG-W is a 27-inch gaming monitor in white, with a 2560 x 1440 (QHD) Fast IPS panel running at up to 180Hz. It combines the fast response gamers look for with USB-C connectivity, so a single cable can carry the picture from a compatible laptop. Here is what the main specs mean in use.

1440p on 27 inches

QHD, at 2560 x 1440, has about 78 percent more pixels than Full HD. On a 27-inch screen, that typically gives a noticeably sharper image than 1080p, while remaining easier for a graphics card to drive than 4K. It is a common pairing for 27-inch gaming monitors for that reason.

180Hz refresh and 1ms response

Refresh rate is the number of times per second the screen updates. At 180Hz, motion looks smoother than on a 60Hz display, if the computer can produce high frame rates. ASUS lists a 1ms response time (GTG, grey-to-grey), which describes how fast pixels change colour. Manufacturers measure this under favourable conditions, so treat it as a best-case figure.

Fast IPS and colour

Fast IPS is ASUS's name for an IPS-type panel tuned for quick response. IPS panels are typically known for wide viewing angles and consistent colour. The monitor covers 95% of the DCI-P3 gamut, a wider range than standard sRGB that is common for film and many games. ASUS also mentions gray-scale tracking for smooth colour gradation and uniformity.

HDR

The monitor is listed as HDR-capable. At this level, HDR support is generally a compatibility feature rather than the dramatic highlights seen on screens with local dimming or very high brightness, so manage expectations and check the exact HDR specification on ASUS's product page.

ELMB Sync and G-Sync compatibility

ELMB SYNC (Extreme Low Motion Blur Sync) lets ASUS's motion-blur reduction work together with variable refresh rate, which ASUS says cuts ghosting and tearing. The monitor is also G-Sync Compatible, meaning it can use variable refresh rate with supported Nvidia graphics cards. Variable refresh matches the screen to the frame rate to avoid tearing.

USB-C and extras

The USB-C connection lets a compatible laptop or device send video over one cable. Check the ASUS specification for details such as power delivery wattage. The listing also mentions a tripod socket, AI gaming features and DisplayWidget Center software, which lets you change monitor settings with a mouse instead of the on-screen buttons. A three-year warranty is listed.

Size

The monitor measures about 8.6 x 24.2 x 20.1 inches (22 x 61 x 51 cm) with its stand and weighs 14.6 lb (about 6.6 kg), so check your desk depth.

What to check before you buy

• Graphics power: 1440p at 180Hz needs a capable graphics card to reach high frame rates.
• Ports: confirm the video outputs on your computer, and whether your laptop supports video over USB-C.
• Desk space: measure width and depth with the stand.
• Panel type: consider room lighting, since a glossy or matte surface affects reflections.
• HDR expectations: read the exact HDR specification.
• Adjustability: check the stand's height and tilt range against your seating.
