Our Verdict
Dell U2718Q
Dell UltraSharp U2720Q
The Dell U2720Q is a 2020 refresh of the Dell U2718Q. Aside from some slight differences in their outer design and the added USB-C ports on the U2720Q, both monitors offer identical features. Performance is largely the same as well, although the U2720Q has a higher peak brightness, better SDR and HDR color gamuts, and it also has better reflection handling. However, the U2718Q has a faster response time and lower input lag.
