Our Verdict
ViewSonic Elite XG270QG
Dell UltraSharp U2520D
The ViewSonic Elite XG270QG is a bit better overall than the Dell UltraSharp U2520D. The ViewSonic is a much better choice for gaming as it has a 165Hz refresh rate and G-SYNC support. It also has a much quicker response time and lower input lag. The Dell is a slightly better choice for office use as it has better ergonomics, significantly better out-of-the-box color accuracy, and it has a higher pixel density since it's a smaller screen.
