    Hello!

    Have you tested the cable on another computer?

    Have you switched to Computer Mode (or HDMI) on your TV?

    The HDMI video is related to the video driver. The driver may not be installed correctly. Reinstall the video driver using DDU.

    1. Go to your video card manufacturer's website (Links below) > Search for your video card or processor > Download the latest driver.

    AMD:

    Nvidia:

    https://www.nvidia.com/en-us/drivers/

     

    Intel:

    https://www.intel.com/content/www/us/en/download-center/home.html

     

    - If you don’t know which your Video Driver is, press WINDOWS + X > Maximize the window > Select Task Manager > Click the Performance > Take a Screenshot GPU tab.

    1. Download DDU from the website below. Click *** Download DDU "Installer" ***.

    1. Install DDU.

    DISCLAIMER: These sites are not from Microsoft, but they appear to provide accurate and safe information. Be wary of ads that may advertise products that are often classified as PUPs (Potentially Unwanted Products). Research any product advertised on the site before deciding to download and install it.

    1. Enter Safe Mode. Press the shortcut CTRL + R > Type ''msconfig'' (without quotes) > Click on the ''System Boot'' tab > Check the ''Safe Boot'' option > Click ''OK''.
    2. When booting in Safe Mode, search for and open DDU > Select your GPU (Video Card) or CPU (Processor) > Select the AMD, Nvidia or Intel device > Click on "Clean and Restart" > Wait for the program to completely uninstall the driver and restart.
    3. After restarting, exit Safe Mode. Press the CTRL + R shortcut > Type ''msconfig'' (without quotes) > Click on the ''General'' tab, check the ''Normal Startup'' option > Click ''OK''.
    4. When restarting the computer, install the downloaded video driver > Choose the "Express Installation" or "Recommended Installation" option during the installation screen > Restart the computer after completing the installation.

    NOTE: Your computer screen may flash a few times. Don't worry, this is normal.

    1. See if the problem persists.
