    Hello，scooter scooter

    Welcome to posting in the Microsoft Community.

    I understand your frustration with the black screen problem when using the Dell monitor. There may be multiple reasons for this phenomenon. Let's check it step by step based on the information you provided.

    You mentioned that the HDMI message popped up at the bottom corner of the monitor, which means that the monitor did not detect the signal from the computer. This is basically caused by hardware problems and has nothing to do with the Windows system itself. You can check the following aspects first.

    1. Check the connection problem

    • Make sure the HDMI cable and connector are not loose or damaged. Please check carefully whether the cable is plugged in firmly and make sure it is connected directly from the graphics card to the monitor. Sometimes, unplugging the HDMI cable and reinserting it can ensure good contact.

    2. Confirm the input source setting

    • The monitor may not be set to the correct input source. Use the buttons on the monitor to access the menu and check the input source settings to make sure HDMI is selected.

    3. Test the normality of the device

    • Make sure your computer is working properly. You can try to connect another monitor to the current computer, or connect this monitor to other computers to check if the problem persists. If the monitor works properly on other devices, the problem may be with the computer's graphics card or settings.

    4. Check the graphics driver

    • If your computer can start normally and there is sound, but the screen does not display an image, there may be a problem with the graphics driver. You can try to start the computer in safe mode and update or reinstall the graphics driver.

    The above steps have covered almost all the hardware problems that may cause the Dell monitor to black screen. If the problem is still not solved after trying these solutions, you may need to do some more in-depth inspections to locate which part of the hardware is faulty.

    • Check the ports: Look closely at the connection between the monitor and the computer, and try connecting to another port if there is one.
    • Change the cable: Try using another HDMI cable to see if that fixes the problem. Sometimes there may be hidden damage inside the cable, even if it looks intact.
    • Cross-connect test: To further troubleshoot, you can connect the monitor to another computer, or connect another monitor to the current computer. This can help determine if the problem is with the monitor, the computer, or the cable.

    I understand that none of us want to face the possibility of hardware failure, so I suggest that you try the above solutions step by step, hoping to help you find the problem easily. But if you find that there is indeed a possibility of hardware failure after inspection, the most convenient way is to take the computer to an offline computer repair shop for inspection. If you still cannot locate the possible cause through the above tests, you can share with me the information and details you see, and I will explore it further with you. I wish you a happy life and good health!
