How Do Portable Monitors Work?
Portable monitors are lightweight and made to connect with devices like phones, tablets, or consoles. They usually use a USB-C or HDMI cable for video and power. While they don’t have built-in storage or apps, they’re super handy as an extra screen for almost any gadget.
