Developing an external graphics card - USB RRS feed

  • Question

  • I intend to program an external graphics card for Windows.
    The device will be connected with a USB (probably USB 3.0) cable.

    Is there any support for USB-connected external graphic cards in Windows?
    Say, I want for the PC to be able to recognize the external graphic card, the same as it recognizes a printer. Are there any good references to start with? I already read about the built-in USB class drivers but none seem to fit to my needs.

    I know there are external graphic cards already, but am not sure if they're USB-connected.

    Is there any way to do that? (Having the OS send the instructions meant for the GPU through the USB cable and wait for a respond of what pixels to display)

  • these types of video cards are not natively supported by windows. what you see from displaylink and others is working around that lack of support. this is a project that will require 10s of man years to complete, a graphics driver in windows is extremely complicated and you are adding the complexity of the difference between usb and pci on top of it.
