Our Verdict
Gigabyte G27Q
Dell S2721DGF
For gaming, the Dell S2721DGF performs better than the Gigabyte G27Q. The Dell has a higher refresh rate of 165Hz, compared to the Gigabyte's 144Hz, and it has a much faster response time, resulting in a clearer image with less ghosting. The Dell also has better ergonomics and wider viewing angles, but it doesn't get as bright as the Gigabyte.
