Working off a single laptop screen gets limiting fast, especially when you’re juggling tabs, documents, and calls. The Mobile Pixels Duex Float 2 Pro is meant to solve that without turning your desk into a full setup, and it’s currently on sale for $279.99 on StackSocial, down from $389.99. This is a 16-inch portable monitor with a 2560x1600 resolution and a 16:10 aspect ratio, so you get more vertical space than a standard display, meaning you scroll less and see more at a glance when working on spreadsheets or editing documents. The 120Hz refresh rate also makes scrolling and general movement feel smoother than most portable monitors, which still tend to sit at 60Hz.

Instead of sitting beside your laptop, this extra monitor can sit above it, which feels more natural if you’re used to a dual-monitor desk setup. You can still use it in other ways—as a standalone display with its built-in kickstand or flipped around for presentations. It also works across macOS, Windows, Linux, and even devices like the Nintendo Switch or newer Android phones with DeX support, so it’s flexible depending on how you plan to use it.

Setup is simple: A single USB-C cable can handle both power and display, and it supports 65W pass-through charging, so you’re not sacrificing your laptop’s charging port. There’s also a mini-HDMI option if your device doesn’t support full USB-C display output.

The screen itself is good for everyday work. It’s bright enough at 350 nits, has an anti-glare coating, and covers 100% of the sRGB color gamut, so colors look accurate. Built-in speakers are there if you need them, but like most portable monitors, they’re more for convenience than quality. The monitor itself weighs about 2.9 pounds, so it’s not the lightest thing to carry, but if you often work from different places and want more screen space without committing to a fixed setup, this is a practical way to stay productive without carrying a full monitor.
