Nothing is displayed when the HUAWEI MateView/MateView GT monitor is connected to a host

Troubleshooting 1: Check the device connected to the monitor, such as a computer, mobile phone, or tablet

1. Make sure that the device connected to the monitor is powered on and works properly (not in a locked, off, sleep, or hibernation state).
2. Choose Agree in the dialog box that is displayed on the device connected to the monitor.

3. Contact the device vendor to check whether the USB-C port supports projection if the monitor cannot display only when connected to a device using a USB-C port.
4. Try connecting another device to the monitor and check whether the issue persists.

Troubleshooting 2: Check signal cables

1. Make sure to use a standard signal cable (DP or USB-C) and ensure that the cable is inserted correctly. If you are using a non-standard signal cable, check whether the cable works properly by connecting it to a different device.
2. Remove and then re-insert the signal cable.
3. The USB-C to USB-A cable does not support screen projection. Please use the USB-C to USB-C or DP cable that comes with the monitor, or use an HDMI 2.0 or later cable purchased from VMALL.
4. If you use an adapter or adapter cable, pay attention to the following:
   1. Remove and then re-insert the adapter or adapter cable in the correct direction.
      

      When using an adapter or adapter cable, pay attention to the connection direction. Connect the higher-bandwidth port to the host and the lower-bandwidth port to the monitor. For example:

      • DP-to-miniDP: DP and miniDP ports have the same bandwidth and support bidirectional transmission. Both forward and reverse connections are supported.

        

      • miniDP-to-HDMI: The miniDP port should be connected to the host and the HDMI port to the monitor.

        

      • USB-C to HDMI: The USB-C port should be connected to the host and the HDMI port to the monitor.

        

      • USB-C to miniDP: The USB-C port should be connected to the host and the miniDP port to the monitor.

        

   2. Replace the adapter or adapter cable with one that is compatible with the HUAWEI monitor. For details about the compatible models, contact Huawei customer service hotline.
