The Duex Max DS is a 14.1-inch slide-out portable monitor that attaches to the back of a laptop lid and slides out beside the screen, giving you a second 1080p display without a stand or desk space. It uses an IPS panel with USB-C power and video, an aluminum case, and a headphone jack. It suits travelers, field workers and laptop-only users who want dual screens anywhere. Against rivals like the Geminos or standalone USB-C portables, it is more integrated but limited to one extra screen, 60 Hz, and no touch or HDR.

Owners generally like the plug-and-play second screen and the slide-out design for travel. Complaints center on the added weight on the laptop lid and the dependence on a compatible USB-C port.
