    usb monitors using graphics card

    Hi isaac177,

    Thank you for writing to Microsoft Community Forums.

    1. May I know the model number of AOC display monitor?
    2. Is this the first time that you are trying to setup the display using HDMI?

    You can try to use an adaptor (USB/HDMI or VGA as the card has 3 slots) to connect to monitor. I would also suggest you to get in touch with Nvidia to know more about this as there can be output issues while using adaptors and your Graphic card (GTX
    1660 Ti) might not work as expected.

    I suggest you to refer this
    NVidia     support link, and check if that helps.


    Regards,

    graphics card problems

    Hi,

    Your computer makes a noise or beeps from your internal speaker because it failed to detect the graphics card. What we can suggest is for you to try cleaning your graphics card with a pencil eraser. Here are the steps below:

    • Turn your computer off.
    • Pull out your video/graphics card.
    • Rubbed the cold contacts with soft pencil eraser.
    • Connect your video/graphics card back to the computer.
    Kindly note that this is just a temporary fix. If the case still continues, I suggest that you contact your graphics card's manufacturer.

    Let us know how it goes.
