Our Verdict

Dell S2721QS

Dell S2722QC

The Dell S2722QC is an updated version of the Dell S2721QS with many of the same features, but there are a few differences. They're built the same and have similar picture quality with an IPS panel with wide viewing angles and a 4k resolution. However, the main differences are with the inputs: while the S2722QC has a USB-C input and two USB 3.0 inputs, the S2721QS has a DisplayPort input, which the S2722QC doesn't have.
