  • Hi Marty Lanum, I have conveyed your registration concern. Kindly try to register your tablet again tomorrow. 

    As for your black screen issue, may you please try the following steps:

    • Please make sure all the cables are securely connected to your desktop or laptop.

    • Plug the HDMI cable to another computer to test if the problem persists.
    • Change to another HDMI/DVI/VGA cable or port;
    • Change to another adapter if you are using an adapter;
    • Plug the VGA/HDMI/DVI cable to the graphics card if you are using a desktop.
