Our Verdict
Dell UltraSharp U2520D
Lepow Z1 Gamut
The Lepow Z1 Gamut and the Dell UltraSharp U2520D are very different monitors. The Lepow is a compact 1080p portable monitor designed for on-the-go use, while the Dell is a more traditional 1440p desktop monitor. The Dell performs better for most uses, but if you need a monitor that you can carry with you in a backpack, the Lepow is an okay choice, as long as you don't mind its low screen brightness.
