Our Verdict

Dell U2715H

Dell U2718Q

The Dell U2718Q is better than the Dell U2715H. The Dell U2718Q supports HDR and performs decently in that mode. It also has a 4k resolution so you can display more details of your work on the screen. Finally, the Dell U2718Q has a better black uniformity, which is great in dark scenes, and perfect gradient performance with no visible banding.
