Our Verdict

Dell S2721DGF

Gigabyte M27Q (rev. 2.0)

The Dell S2721DGF and the Gigabyte M27Q (rev. 2.0) are 1440p entry-level gaming monitors. The Gigabyte has extra features, like a USB-C port with DisplayPort Alt Mode to quickly connect a laptop. It also has a KVM switch that makes it easy to use the same devices on two sources. The Gigabyte even has much better accuracy out of the box and gets brighter, so it has the advantage in terms of overall picture quality.
