Connecting a pen display to a mobile device

Overview

This guide focuses on how a pen display connects to a mobile device, such as a phone. It is a subset of the broader guide Connecting a pen display, but it focuses on the issues that come up with mobile devices.

Key requirements and realities

  • USB-C port on the mobile device

    • Your mobile device must have a USB-C port.

    • Your mobile device's USB-C port must support DP alt mode. Not all USB-C ports support DP alt mode.

  • USB-C cable connecting the phone to the tablet

    • This cable must also support DP alt mode.

  • Compatibility between pen display and a phone

    • Even if your phone's USB-C port supports DP alt mode, your phone still may not support pen displays. A good example is iPhones. They do not work with pen displays.

    • A pen display may be compatible with some mobile devices but not others. You should contact the manufacturer and ensure which phones they support with their tablets.

  • Power

    • Your pen display needs power from somewhere.

    • Most likely, your mobile device cannot provide enough power, so you will need a separate power source.
