Overview
Same panel size, same QHD resolution, very different desks. The Gigabyte M27Q3 is a 27-inch IPS monitor reaching 300 Hz natively and 320 Hz overclocked, with 400 nits, DisplayHDR 400 and 1000:1 contrast. The Gigabyte G27Q3 matches the 320 Hz ceiling over DisplayPort but only at 300 nits and 1300:1 contrast, and HDMI is capped at 144 Hz. The real separator in this M27Q3 vs G27Q3 comparison is connectivity: the M27Q3 packs an 18W USB-C port, a KVM switch, two USB-A ports and two HDMI 2.1 inputs, while the G27Q3 has no USB and no speakers.
