27-inch 320Hz QHD IPS Gaming Monitor

The Acer Nitro KG271U F3bmiipx is a 27-inch flat IPS panel with a 2560 x 1440 QHD resolution and a 320Hz maximum refresh rate. It delivers 1.07 billion colours with 90% DCI-P3 coverage and a 1ms grey-to-grey response time that can reach 0.5ms in overdrive. AMD FreeSync Premium adaptive sync is supported over the display inputs.

Competitive gamers needing high motion clarity

This monitor suits players who prioritise fast refresh rates and low response times at QHD resolution for competitive titles. The zero-frame design also helps multi-monitor setups. Buyers who want higher pixel density for productivity or larger screen sizes for immersion should look at something else. Users requiring factory calibration reports or hardware calibration support will not find those features here.

Check GPU outputs and cable bandwidth

Verify that your graphics card can drive 2560 x 1440 at 320Hz over DisplayPort 1.4 or HDMI 2.1 before ordering. The monitor provides one DisplayPort 1.4 and two HDMI 2.1 ports, so confirm you have the matching cable standard for the chosen input. Ensure your operating system and drivers support the full refresh rate at the native resolution.
