what this red dot?


  • Hi gendis py, the following are the possible causes of this issue:

    1. defective cable
    2. defective computer display port (HDMI, DVI, DisplayPort, VGA, or USB-C)
    3. defective tablet display

    Thus, kindly try the following steps to help us determine the cause or at least eliminate the possible causes:

    1. If you have a spare display cable (HDMI, DVI, DisplayPort, VGA, or USB-C), please try a different cable.
    2. If you can access another computer, try connecting your tablet display on another computer and check if you continue having the same issue.

    If the steps above result to having the same issue, please let me know so I can create a ticket for you. 

    Best Regards,

    HUION Customer Support
