The aluminium one. Two screens, one cable, 30 millimetres thin. The Dual Boost Pro 14 is the model to buy if you care how it's built. A full-aluminium chassis, matte anti-glare IPS panels, and a folded profile thinner than most hardcover books. It draws power and video from a single USB-C cable, so there's no second charger to leave behind in a hotel room. What you get 2 × 14″ matte IPS panels, 1920 × 1080 each, 1200:1 contrast, 65 Hz, 72% NTSC Single USB-C connection — no external power supply Full-aluminium body, 353 × 208 × 30 mm folded, 2.00 kg Fits laptops 12″ to 16″ · macOS (M1–M4 and Intel), Windows, Android, Linux In the box: monitor, USB-C to USB-C cable, USB-C to USB-A cable, USB key with software, manual Two things to know There are no built-in speakers — audio plays through your laptop.
