Problem

Nothing is displayed when the monitor is powered on and connected to a computer, phone, or tablet.

Cause

This issue may be caused by the computer status and cable connection. Refer to the following possible reasons:

1. The computer, phone, or tablet is not powered on or is in hibernation mode.

2. The signal cable (DP/HDMI/USB-C) of the monitor or connected device is not inserted properly.

3. The device connected to the monitor is not working properly.

4. The USB-C port on certain devices does not support displaying images.

5. A non-standard USB-C cable is used.

Solution

Step 1: Make sure that the device connected to the monitor is working properly.

Step 2: Use the standard signal cable (DP/USB-C) of the monitor and ensure that the cable is inserted properly. If a non-standard signal cable is used, ensure that the cable works properly on other devices.

Step 3: Connect the device to another monitor and check whether the display is normal.
