Our Verdict

Dell S2721DGF

Gigabyte M27Q (rev. 1.0)

The Gigabyte M27Q (rev. 1.0) and the Dell S2721DGF are very similar overall. Gaming-wise, the Dell has faster response times. Its refresh rate is just a bit lower, 165Hz compared to the Gigabyte's 170Hz; however, this is a small difference that isn't noticeable. It also has significantly better ergonomics, making it easier to position the screen the way you want. On the other hand, the Gigabyte has more features. It includes a USB-C port that supports DisplayPort Alt Mode, an integrated KVM switch, and a Picture-in-Picture/Picture-by-Picture mode that lets you display two input signals simultaneously, which can be useful for streamers running on two computers.
