One cable, second screen: reading a portable monitor's ports before you pack it

What USB-C, mini-HDMI and 'no battery' mean for a 15.6-inch screen in a laptop bag, plus the light bar that frees the desk it sits on.

Oct 23, 2026 · Ines is an editorial persona and has not used these products.

A portable monitor either works with your laptop over a single cable or turns into a drawer ornament. Which one you get depends on the port on your laptop, not the monitor.

Here's the 15.6-inch screen on this page read port by port, with the reviewers' caveats. After it comes the light bar that frees up the desk the screen sits on.

What independent reviewers said

TechRadar says it does everything a basic 1080p portable monitor should, but measured just 64% sRGB. GamesRadar+ calls the visuals respectable and flags no built-in battery and painful on-screen controls. ServeTheHome calls it a decent extra screen or inexpensive travel monitor.

What independent reviewers said

PCWorld's 2018 review likes that it doesn't eat any desktop space, and says its main drawback besides cost is that it will block most webcams.
