Our Verdict
LG 27GN850-B/27GN880-B
Gigabyte M27Q (rev. 1.0)
The LG 27GN850-B/27GN880-B and the Gigabyte M27Q (rev. 1.0) are both great 1440p IPS gaming monitors. They perform very similarly gaming-wise; the Gigabyte has a higher refresh rate of 170Hz, but the LG has a better response time. The Gigabyte offers more features, such as a USB-C input that supports DisplayPort and charging, a Picture-in-Picture mode, and a KVM. It also has a wider color gamut for HDR and gets much brighter overall.
