A skinny portable monitor should have a skinny price tag, but this Amazon deal is taking it a little far. For a limited time you can take 44% off the price of MNN’s 15.6-inch FHD portable monitor, which means you can add a big, immersive second display to a wide range of devices for just $50.

The MNN is a plug-and-play external display with a full HD IPS panel, dual USB-C ports, and a protective cover that doubles as a stand. It can be powered directly from a laptop’s full-function USB-C port, or via a 5V USB-A to C adapter (not included). It’s perfect for taking on the road as a second screen for a laptop, as a gaming console screen for road trips, or as a bigger screen to show photos or videos from your smartphone or tablet.

Slender, Man

The MNN monitor measures in at an incredibly skinny 0.3 inches of thickness and weighs just a hair over 1.5 pounds. It’s easy to slide into a backpack or carry-on bag, and its cover that doubles as a stand protects the screen when you’re transporting it.

The 15.6-inch IPS matte panel runs at 1920 x 1080 resolution with a 178-degree viewing angle, which means color accuracy and brightness hold up whether you’re looking straight on or at an angle. The matte finish cuts glare in brighter environments — a small but meaningful advantage over glossy panels in office or outdoor use. Blue light reduction and flicker-free operation round out the eye-care features for people logging long hours in front of it.

Two full-function USB-C ports and one HDMI port give you a full range of connectivity. A single USB-C cable handles both power and display signal simultaneously when your device supports Thunderbolt 3 or USB 3.1 with DisplayPort Alt Mode — so the setup is genuinely one-cable-and-go for compatible laptops and MacBooks. If your device doesn’t meet that spec, HDMI gets the job done instead. The monitor is compatible with PS4, PS5, Xbox, and Nintendo Switch over HDMI, so it pulls double duty as a travel gaming screen without any additional configuration.

Many Modes of Monitoring

The MNN portable monitor gives you the standard range of display modes: extended, copy, second screen, and portrait. HDR mode is available for content that supports it, pushing highlights brighter and shadows deeper than the standard profile. Portrait orientation is worth calling out specifically — it’s a genuinely useful configuration for reading long documents, running a vertical code editor, or stacking a secondary window without horizontal scrolling.

A $50 second monitor would have been virtually unheard of even a few short years ago, especially one that’s so readily portable and works so well across tech devices. The MNN portable 15.6-inch FHD normally sells for a far more realistic $90, and it’s a solid buy at that price. But while Amazon’s practically giving them away for just $50, it’s a must-add to your tech stack.
