Our Verdict
Lepow Z1
ViewSonic VG1655
The Lepow Z1 and the ViewSonic VG1655 are both acceptable portable monitors. They each have a 1080p resolution with a 15 inch screen, and each delivers clear text. They both have two USB-C inputs, but only one supports DisplayPort Alt Mode on the Lepow while both support it on the ViewSonic. The Lepow supports HDR, which the ViewSonic, but it doesn't add much. The ViewSonic has better ergonomics because it has an adjustable incline stand, while you can only set the Lepow's stand to three settings.
