What are Portable Monitors?

A portable monitor is a lightweight, thin external display that can be connected to laptops, smartphones, gaming consoles, cameras, and other devices to provide an additional screen. Portable monitors allow you to expand your viewing real estate and multitask more efficiently on the go.
Unlike desktop monitors, portable monitors do not require a power socket and are powered either via the device they are connected to or by built-in battery packs. They feature slim profiles from 8mm to 15mm thickness thanks to the LED-backlit LCD panel technology. Common portable monitor screen sizes range between 10 inches to 17 inches diagonally.
Portable displays can connect to devices via USB-C, mini HDMI, or full-size HDMI ports. Some models may still sport older VGA or DisplayPort connectors. Panel types available in portable monitors include IPS, TN, and VA, with IPS offering the best color reproduction and wide viewing angles ideal for color-critical work.

Famous use cases for portable monitors include:

  • Expanding laptop screen space for increased productivity
  • Extending smartphone/tablet displays for easier touch input
  • Gaming with console systems like the Nintendo Switch
  • Photo and video editing on the fly with mirrorless cameras
  • Presentations, meetings, trade shows requiring a second screen
