What I like

We recommend buying a portable monitor that has a USB-C port with DisplayPort Alternate Mode and USB Power Delivery. The DisplayPort Alternate Mode turns the USB-C port into a video input, and USB Power Delivery can be used to power the portable monitor. This enables a single-cable connection between the portable monitor and a laptop, desktop, or tablet with USB-C.

Alongside these general benefits, each of Arzopa’s portable monitor options comes with its own unique benefits.
