What ports and connectivity should a portable monitor have?
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.An ideal portable monitor should pair USB-C with a backup video input, such as HDMI or DisplayPort, for connecting devices that lack USB-C. Most portable monitors offer this feature, but the HDMI or DisplayPort input is usually a sma

A monitor with a 13.3-inch panel is great for frequent fliers and other travelers looking to pack light. A 13.3-inch model will typically weigh about a quarter- to half-pound less than a 15.6-inch model. The downside, of course, is a smaller display that can feel cramped, which can make a 13.3-inch display frustrating. 15.6-inch portable monitors are a better choice in many situations, as viewing the display for l
