This Portable 16-Inch Second Monitor Is Now on Sale for $280.
Working with a single laptop screen quickly becomes awkward, especially when you need to open tabs, work on documents, and make calls simultaneously. The Mobile Pixels Duex Float 2 Pro monitor aims to solve this problem without turning your desktop into a full-fledged workstation, and it’s now on sale for $279.99 at StackSocial , down from $389.99. This 16-inch portable monitor features a 2560×1600 resolution and a 16:10 aspect ratio, giving you more vertical real estate than a standard display, meaning less scrolling and more information at a glance when working on spreadsheets or editing documents. The 120Hz refresh rate also makes scrolling and overall movement smoother than most portable monitors, which typically operate at 60Hz.
Instead of placing it next to your laptop, this additional monitor can be positioned above it, which feels more natural if you’re used to a dual-monitor desktop setup. You can also use it in other ways—as a separate display with the built-in stand or rotated for presentations. It also works on macOS, Windows, Linux, and even devices like the Nintendo Switch or newer Android phones with DeX support, so its flexibility depends on how you plan to use it.
Setup is simple: a single USB-C cable delivers both power and display signal, and supports 65W pass-through charging, so you don’t have to sacrifice your laptop’s charging port. A mini-HDMI option is also available if your device doesn’t support USB-C display output.
The screen itself is well-suited 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. There are built-in speakers if you need them, but like most portable monitors, they’re more for convenience than sound quality. The monitor itself weighs about 1.3 kg, so it’s not the lightest to carry, but if you frequently work from different locations and want more screen space without being tied to a stationary setup, this is a practical way to stay productive without lugging around a full-size monitor .
