USB Mobile Monitor

The USB Mobile Monitor allows you to connect your Android mobile phone or tablet to your PC or other device with a simple USB Cable. All that is required is the download of the USB Mobile Monitor App on your device and the installation of the USB Mobile Monitor software on your PC or device (More information in the Usage section.) USB Mobile Monitor works for Desktops and Servers from Windows XP to Windows 10 and Server 2019. Starting with version, Linux drivers for Raspberry Pi and other Linux based systems have been added.

Why should I Use it?

    • See what is happening on your PC or device and fully control it without the need for a remote connection! Can also be used to monitor a Linux based device such as the Raspberry Pi.
    • Use your mobile device as a secondary display or monitor with easy switching between multiple monitors. The Multi-touch emulation feature allows you to use the tablet as a true multi-touch device for you PC.
    • No need to plug and unplug cables, a single USB cable plugs-in to the front of the PC. Saves you from back-pain and dirtying yourself in dusty places.
    • Can be used within a virtual machine to provide a separate monitor for each of you virtual machines.
    • It is light-weight, doesn't require a complex installation and doesn't take up much space in your PC, phone or tablet.
    • No Network, Internet or WiFi connection is required. Works with PCs that do not support Remote Desktop such as Windows Home versions or with PCs that do not have a network connection

  • Device drivers are required to connect your PC to your Android device. Follow these steps to install the device drivers:

    1. Connect your device to the PC using a standard USB cable. If your PC is configured to automatically install device drivers and this is the first time you connect the device, Windows will start installing the default device drivers for the device. Allow the device driver installation to finish before going forward. If your PC is configured not to automatically install device drivers, proceed to the next step right away.
    2. Download the USB Mobile Monitor installation package
    3. When asked to Open or Save, click on Open
    4. Inside the compressed, you will find usbmmInst.exe, double-click on that file to start the Installation
    5. Follow the installation instructions. The screen will flicker during the installation of the drivers which is normal.
    6. The installer will ask you to unplug the device and plug-it back again, please do so.
    7. Click on Close to finish the installation. If the Android App is already installed on the device, your PC screen will appear on the device, if not proceed to the device installation step. If the PC screen does not appear on the device, a reboot of your PC might be required.
    8. On some occasions, MS Windows might overwrite the USB Mobile Monitor drivers with the device specific drivers. In this case, the PC screen will not show up on the device and it is sufficient to restart the installation process from step 2 without uninstalling the device drivers. You should also repeat the same installation steps when USB Mobile Monitor is used on the same PC but with a new device.
    9. To uninstall the USB Mobile Monitor, go to the control panel, programs and features, select USB Mobile Monitor and click uninstall. Alternatively, you can run Uninstall.exe directly from c:\users\[your user name]\AppData\Local\USB Mobile Monitor.
    10. To update to a newer version, always uninstall USB Mobile Monitor first, reboot your system (optional but recommended), then reinstall the new version using usbmmInst.exe.
  • The device installation can be done before or after the PC installation by following these steps:
    • Make sure that the option "USB Debugging" is activated in the Settings -> Developer options of your device
