Trio 12.5" Portable Monitor

The Mobile Pixels Trio is a 12.5" portable monitor built for professionals and students who need a second screen while travelling. It connects through USB Type-C or USB Type-A and works with Windows, macOS, Android and Nintendo Switch. Plug-and-play operation means no driver installation is required. The magnetic attachment secures the panel to the back of a laptop for quick setup.

Magnetic Mount and Dual USB Inputs

A magnetic backing lets the monitor snap onto the lid of most laptops without clips or stands. Two input options, USB Type-C and USB Type-A, cover modern and legacy ports on the same cable. The 16:9 panel reaches 300 cd/m2 brightness for clear viewing indoors. Widescreen format matches standard laptop displays for a consistent workspace.

1920 x 1080 at 60 Hz

The display delivers a 1920 x 1080 resolution at a 60 Hz refresh rate, suitable for office applications, coding and video playback. This specification determines whether the panel meets the clarity and motion requirements of your workflow. Buyers who need higher refresh rates or 4K detail should look elsewhere. The 12.5" diagonal keeps the unit compact for travel bags.
