Mobile Pixels Duex Max DS Screen Extender

Pros

• +Magnetic laptop-lid mount attaches directly to the laptop — nothing separate to pack or forget
• +Single USB-C (or HDMI) cable handles video and power on most laptops with sufficient USB-C delivery
• +Compatible across macOS, Windows, Android, and Nintendo Switch per the listing with no driver install
• +Sold and shipped directly by Mobile Pixels Inc, the brand that built the lid-mount category
• +14.1-inch panel is the larger of the two Duex sizes in this lineup

Cons

• −1080p on a 14.1-inch panel is standard resolution, not sharp text at close range vs. the Trio's QHD panels
• −Tied to your specific laptop's lid geometry — confirm the mounting bracket fits before switching laptops
• −No power pass-through — draws from the laptop's own USB-C power budget
• −$199.99 is a real spend for a single-panel extender
