USB-C Hub Common Problems and Solutions Guide
I. Solutions for HDMI Port Not Working on USB-C Hub
If you encounter the situation that the HDMI port is not working when using a USB-C hub, you can troubleshoot it by following the steps below:
1. Check compatibility: Make sure that the USB-C hub is compatible with your device. Some hubs have specific requirements or restrictions on the devices they support, and mismatches may cause malfunctions.
2. Secure connection: Double-check that the USB-C hub is firmly connected to the USB-C port of the device. If it is a detachable connection, you can re-plug it to ensure that the connection is correct.
3. Power check: Some USB-C hubs, especially those with multiple ports or used to support high-power devices, may require external power supply. Please check whether your hub has this requirement and make sure that the external power supply is properly connected.
4. Update drivers: Keep your device's operating system and drivers up to date. Sometimes, firmware or driver updates are required to ensure normal operation.
5. Try another HDMI cable: The problem may be with the HDMI cable itself. You can replace another HDMI cable to test the hub to see if the problem persists.
6. Cable monitor/TV input detection: Confirm that the HDMI input on the monitor or TV is functioning properly. You can use another device to connect to the monitor for testing to rule out a monitor or TV problem.
7. Check the display settings: On the device, check the display settings to ensure that it is correctly configured to output to the HDMI port on the USB-C hub. Some devices may need to be manually configured.
8. Restart the device: Simply restarting the device and the USB-C hub can sometimes resolve connection issues.

III. Display problems and solutions after connecting the USB-C hub
When connecting the device to the USB-C hub, if display problems such as flickering, black screen, white screen or blue screen occur immediately, you can follow the steps below to troubleshoot and solve the problem:
1. Check the cable connection: Make sure the USB-C cable connecting the device to the USB-C hub is firmly inserted. You can also consider trying to replace a different cable to rule out the possibility that the problem is caused by the cable.
2. Power confirmation: Confirm that the USB-C hub is receiving sufficient power. Some USB-C hubs require external power support, especially when connecting high-power devices.
3. Hub compatibility verification: Verify that the USB-C hub is compatible with your device. Different devices may have specific requirements or restrictions on the supported hubs.
4. Update drivers: Keep your device's operating system and drivers up to date. You can visit the manufacturer's official website to download and install the latest drivers for the USB-C hub and device.
5. Try another port: If the USB-C hub has multiple ports, try connecting the device to a different port to check if the problem persists.
6. Test without a hub: Disconnect the USB-C hub and connect the device directly to the monitor to determine whether the problem is caused by the hub or is related to the device or monitor.
7. Display Settings Check: Review the display settings on your device to make sure they are correctly configured to output to the connected display through the USB-C hub. If necessary, adjust the settings accordingly.
8. Hub Firmware Update: Check if there is a firmware update for the USB-C hub. Updating the hub's firmware may resolve compatibility or performance issues.
Note: If you encounter any problems using our products, please contact us first to confirm whether you need to install a driver. Some products do not require driver installation, and installing drivers unnecessarily may cause the product to malfunction. Also verify that the monitor or TV connected to the USB-C hub supports the resolution and refresh rate configured on the device.
