Clip two screens onto your laptop, stack a second pair above it, or carry a 4K screen in your bag. Here is the whole PORNITOR range, what each model connects to and which one fits your laptop.
On a full-function USB-C port (DisplayPort Alt Mode) one cable carries picture and power. No drivers to install.
Extenders ride on the laptop lid, stacked screens sit beside it, portable monitors stand anywhere.
Windows, macOS, ChromeOS, Android phones and game consoles. Check the Mac notes below for multi-screen models.
Screens that attach to the lid of your laptop and fold out to the side. The triple model adds a screen on each side; the single models add one that rotates into portrait.
Two 14-inch 1080p IPS screens that unfold on both sides of your laptop, turning it into a three-screen workstation. A built-in kickstand carries the weight, so the laptop hinge is not doing all the work.

A sharper stacked pair: two 2560×1440 panels on a foldable stand that rotates 180°. It has HDMI and two full-function USB-C ports. Pornitor sells this one for Windows laptops only, so Mac users should pick the 1080p stacked model.
