The Acer KGB271U is a 27-inch 1440p gaming monitor built on an IPS panel with a 200 Hz refresh rate and a 1 ms response time. The IPS panel gives wide viewing angles and better color than the TN and VA panels common at this tier, and the 200 Hz rate sits above the 144–165 Hz of most 1440p rivals. Brightness is modest at 250 cd/m² and the stand is basic, so it suits gamers who want speed and resolution over HDR or a premium mount.
