Our Verdict
Dell S2721DGF
Dell S2722QC
The Dell S2721DGF and the Dell S2722QC are different types of monitors. The S2722QC is designed for productivity, as it has a 4k screen and more office features like a USB-C input and Picture-in-Picture and Picture-by-Picture modes, meaning you can connect two devices. The S2721DGF is designed for gaming as it has a much higher 165Hz refresh rate and much quicker response times, too. The S2721DGF also has a local dimming feature, which the S2722QC doesn't have, but it performs terribly.
