Working on a single 13-inch or 15-inch laptop display when you're away from your desk can feel like trying to run a business through a keyhole. Toggling between spreadsheets, browser tabs, and Slack messages slows down your output and destroys focus.
Enter the Mobile Pixels Duex Max—a 14.1-inch portable monitor that attaches magnetically to the back of your laptop, giving you a full two-screen setup wherever you open your bag.
We spent two weeks testing the Duex Max across coffee shops, home offices, and airport lounges to see if it lives up to the productivity hype. Here is our full break-down.
Display Size: 14.1 inches
Resolution: 1920 x 1080 Full HD (60 Hz)
Weight: 1.8 lbs (816 g)
Brightness: 300 nits (Adjustable)
Connectivity: Hybrid Signal USB-C / Mini HDMI
Compatibility: macOS, Windows, Android (DeX), Nintendo Switch
The first thing you notice about the Duex Max is how compact it folds. Made from a mix of PC-ABS plastic and aluminum alloy, it balances durability with weight. At just 1.8 lbs and 0.25 inches thick at its narrowest point, it adds minimal bulk to your laptop sleeve.
The magnetic attachment system utilizes four small metallic pads that adhere to the back of your laptop lid. Once installed, the monitor glides smoothly out to the left or right side.
Setting up the Duex Max takes less than five minutes:
Use the provided placement guide to stick the four adhesive magnetic pads to your laptop lid.
Snap the Duex Max housing onto the magnets.
Slide out the screen and connect the included USB-C cable into your laptop.
Because it uses DisplayPort Alt Mode via USB-C, it is true plug-and-play—no power bricks, extra wall outlets, or bulky video cards required.
The 1080p IPS panel delivers sharp text and solid color representation for everyday tasks. The 300-nit maximum brightness keeps content readable near bright coffee shop windows.
The screen offers four versatile viewing modes:
Dual-Screen Mode: Slide it out to the side for effortless multitasking.
Presentation Mode: Swivel the display 180° to mirror your screen to someone sitting across from you.
Portrait Mode: Detach the monitor and stand it vertically—ideal for coding, document reading, or monitoring chat streams.
Eye-Care Mode: Reduces blue light output during long night sessions.
Seamless Portability: Stays attached to your laptop so you never leave it behind.
Single-Cable Solution: Power and display run through one cable.
Auto-Rotation: G-sensor automatically flips the display orientation depending on which side you position it.
Low Power Consumption: Consumes only ~4.5W, preserving your laptop's battery life.
Lid Weight: Lighter ultra-portable laptops may tilt back if the hinge isn't stiff.
Not for Heavy Gaming: The 60Hz panel is built for productivity rather than competitive gaming.
If you frequently work away from a dual-monitor desktop setup, the Mobile Pixels Duex Max is worth every penny. It bridges the gap between portable flexibility and desktop-level productivity, eliminating tab-switching fatigue on the go.
