Plug one end into the Android phone, the other into the portable monitor.
Switch to desktop mode on your Android phone (if available):
Samsung → DeX Mode
Huawei → Easy Projection
Connect external power (if needed):
Some portable monitors like the 23 inch monitor or mini LED computer monitor come with power input and may need external power supply.
Others are completely bus-powered and can work straight from the USB-C connection.

If your phone doesn’t have DisplayPort Alt Mode support, there’s still hope to connect wirelessly. Options include:
Miracast: Use the Miracast wireless display connection on most Android phones.
Chromecast or Apple TV: Wirelessly stream from Android or iOS device using screen mirroring feature.
