Our Verdict
Gigabyte M27Q (rev. 2.0)
ASUS ROG Strix XG27ACS
The ASUS ROG Strix XG27ACS and the Gigabyte M27Q (rev. 2.0) are both low-cost 1440p gaming monitors. They share similar specs and performance, but the ASUS has an advantage for gaming because it has better motion handling. On the other hand, the Gigabyte is better for multitasking because it has a KVM switch, making it easier to use different devices on different sources connected to the monitor.
