Its got a USB port that allows for power delivery, and its ergonomics are very good. Its 27-inch screen offers more screen real estate than the AOC 24G2 and boasts wide viewing angles for easy group viewing.

Consensus

our Verdict

Most critics praised the Dell U2721DE as a great monitor to use in the office. They were impressed with its superb ergonomics and hailed it for being very easy to adjust. Product testers from Rtings were very much pleased with its wide viewing angles, as they had an easy time adjusting it to their preferences. Critics from Monitor Nerds were also delighted with its color accuracy after calibration and felt that the display would be okay for light photo editing. Its refresh rate may not be as high as the Dell S3422DWG’s 144Hz, but it offers great connectivity options thanks to a wide port selection.

Despite all these benefits, the Dell U2721DE still has several issues that experts were not too happy about. They established that the monitor’s contrast ratio was too low for dark room viewing, and that it does not have support for HDR content.
