Overview

Sharpness against speed frames this decision. The Gigabyte G27Q3 is a 27-inch IPS panel at 2560 x 1440 (109 ppi) that reaches 320 Hz over DisplayPort, with 300 nits and 1300:1 contrast. The Gigabyte G27U keeps the 27-inch IPS size but jumps to 3840 x 2160 (163 ppi) at 160 Hz, with a dual mode that drops to Full HD for 320 Hz. It is also brighter at 350 nits and adds a USB-A port, while the G27Q3 has no USB at all. Both offer two HDMI inputs and one DisplayPort, so this G27Q3 vs G27U question is mostly about resolution.

Verdict
Bottom line

Grab the G27Q3 if esports frame rate matters most, since it hits 320 Hz at QHD. Take the G27U if you want 4K sharpness at 163 ppi, 350 nits and a Full HD 320 Hz mode for shooters. The G27U is the more flexible monitor, and resolution is the deciding factor.

Buy this ifGIGABYTE G27Q3
  • 320 Hz at QHD over DisplayPort
  • 1300:1 contrast, slightly above the G27U
  • 109 ppi QHD is easier on the GPU
Buy this ifGIGABYTE G27U
  • 4K at 163 ppi with 160 Hz refresh
  • Full HD 320 Hz dual mode for shooters
  • 350 nits plus a USB-A port
