Specifications
| Screens | 2 × 14.1" 2240×1400 IPS; 16:10, 300 nits, 100% sRGB, 60 Hz (the manual; one store table says 120 Hz) |
|---|---|
| Fits | 15–16" laptops (Mobile Pixels); Macworld ran it on a 14-inch MacBook Pro and lists 13–16-inch MacBooks |
| Connection | USB-C Alt Mode or driver; one cable per screen with no driver if the laptop has two video-capable USB-C ports, one cable for both screens only with Mobile Pixels' display driver (a DisplayLink-style virtual display) |
| MacBook Air M1 / M2 / M3 | These run one external screen natively with the lid open, so both side screens need the driver; an M4 Air runs both natively over two cables |
| Power | From the laptop's USB-C, under 13 W (about 7.5 W at default brightness); a 15 W+ PD charger is needed for full brightness; two USB-C ports with 65 W pass-through charging |
| Weight / size | 4.13 lb (about 1.9 kg); 13.44 × 8.83 × 0.9" folded |
| Stand | Built-in kickstand cover; four laptop magnets included; landscape, portrait, presentation and collaboration modes |
| In the box | 2× USB-C cables (0.5 m) with USB-A adapters, 4 magnets |
Model: Trio 3 Pro (1400p). Figures are from the manufacturer's official product page unless a caveat says otherwise.
Compared side by side
The Mobile Pixels Trio 3 Pro Triple Laptop Screen Extender appears in these tables next to models from other brands:
- Best triple screen laptop extender for MacBook Air (2026): M1, M2 and M3
- Best triple-screen laptop extender for a 16-inch laptop with 1920×1200 panels (2026)
- Best triple laptop screen extender, and which laptops can run both side screens
Who it's for
15–16-inch laptop users who want three screens on the road; 14-inch works per reviews.
Caveats
- One-cable setup needs Mobile Pixels' driver; without it each screen needs its own video-capable USB-C port.
- On a base M1, M2 or M3 MacBook Air (lid open) the second side screen only works through the driver.
- Amazon had it for $423.99 from Mobile Pixels itself on 2026-11-02, $9.50 less than the store.
- 300 nits, and the laptop's port can't power full brightness; plug a charger into the Trio for that.
- 4.1 lb added to the laptop lid; some owners find the magnets weak.
