27-inch 180Hz QHD gaming monitor

The ASUS ROG Strix XG27ACG is a 27-inch QHD display built for competitive gaming. Its Fast IPS panel delivers a 2560 x 1440 resolution at an 180Hz refresh rate. AMD FreeSync and G-Sync Compatible support keep motion smooth. The panel covers 95% of the DCI-P3 gamut for accurate colour.

Thermals noise and power in normal use

The monitor uses an LED backlight with a typical brightness of 400 cd/m² and a 1000:1 contrast ratio. Anti-glare coating reduces reflections in bright rooms. There are no built-in speakers or webcam, so the unit runs silently. A USB Type-C port with DP Alt Mode handles video and data over a single cable.

Sustained load behaviour

ASUS Extreme Low Motion Blur Sync works alongside variable refresh rate to suppress ghosting during long sessions. The 1ms grey-to-grey response time keeps fast movement sharp at high frame rates. The stand provides tilt, swivel, pivot and 120mm height adjustment for ergonomic comfort. VESA 100 x 100mm mounting is also supported.

Questions about this item

How do I attach the stand to the VESA 100 x 100mm holes on the back of the XG27ACG, and which step do people often skip?

Align the stand bracket with the four 100mm spaced holes, insert the supplied screws fully, then tighten them evenly; many users forget to lock the quick-release latch after the screws are seated.

What part of the XG27ACG will need replacement first after long daily use?

The LED backlight is rated for tens of thousands of hours; it will dim gradually before any other component requires service.

Which limit appears first when the XG27ACG runs at 180Hz with HDR400 content for hours?

Sustained 400 cd/m² HDR output can trigger automatic brightness limiting to protect the panel, reducing peak luminance before thermal throttling affects the 180Hz refresh rate.
