If your external display is not working with the Aluminum Type-C Mobile Pro Hub Adapter, the two most common causes are a case on your tablet or phone stopping the hub from seating, and a video adapter or conversion cable in the chain instead of a direct HDMI cable. The Aluminum Type-C Mobile Pro Hub Adapter is plug and play with no extra drivers required, and its HDMI port needs a direct HDMI to HDMI connection.

How to fix display problems with the Aluminum Type-C Mobile Pro Hub Adapter

1. Remove the case from your tablet or phone. The Aluminum Type-C Mobile Pro Hub Adapter is not compatible with cases, which keep it from seating fully in the USB-C port.
2. Push the hub all the way into the USB-C port on your iPad Pro, USB-C tablet, or USB-C smartphone.
3. Connect your monitor with a direct HDMI to HDMI cable. Conversion cables and adapters, including DVI to HDMI and VGA, are not recommended and are a common reason the screen stays blank.
4. Switch your monitor or TV to the HDMI input you actually plugged into.
5. Try a different HDMI cable.
6. Connect the display straight to your device without the hub to confirm the display and cable both work.
7. Unplug the Aluminum Type-C Mobile Pro Hub Adapter, wait a few seconds, then reconnect it and check again.
8. Set the right expectation on refresh rate. The HDMI port on the Aluminum Type-C Mobile Pro Hub Adapter runs at 30Hz.
9. Connect a USB-C charging cable to the hub's USB-C Power Delivery (PD) port to keep your device powered while the display is connected. The pass-through supports up to 60W, and your device's original USB-C power cable is recommended.
10. Do not install any drivers. All ports on the Aluminum Type-C Mobile Pro Hub Adapter can be used at the same time and no extra software is needed.
