The product, explained
About the ASUS XG27ACS
ASUS 90LM09Q0-B01170 is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 2560 x 1440 pixels; panel type: Fast IPS; maximum refresh rate: 180 Hz. This entry covers manufacturer code 90LM09Q0-B01170. Specifications relate to this exact source record; other editions or packages may differ.
The 68.6 cm (27") display is specified at 2560 x 1440 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 180 Hz. To use it, the source device, cable, resolution and input must all support the intended mode. Refresh rate is separate from response time and input lag.

4.50 / 5Original rating: 90 / 100
Review covers ASUS ROG Strix XG27ACS. The verified product-data labels bind this public model name to code 90LM09Q0-B01170, and the original publisher article independently supplies the editorial score. This is not proof that the supplier supplied this review URL, or that the reviewer tested this colour or included accessories.

4.00 / 5Publisher rating supplied by Icecat: 80%
1440p on a 27-inch panel is arguably still the best choice for mainstream PC gaming. It's also cheaper than ever, with even high-refresh options dipping below $200. In that context, the new Asus ROG Strix XG27ACS doesn't immediately look like a bargain.Fo...
