    I have an external monitor (Dell UltraSharp U2717D 27) connected to my MBP via a DisplayPort to USB-C cable.

    I just bought a Logitech webcam (C920) that comes with a USB-A cable.

    Can I plug the webcam USB-A cable directly into the Dell UltraSharp and expect the signal to carry though the DisplayPort to USB-C on my MBP?

    If not, what's the best way to get this bad boy to work with my MBP?

    thanks in advance!

    display port won't carry USB

    you'll need a USB to USB-C adapter,
    it will have a USB-C that plugs into your laptop, and then an "old style" USB port to plug the camera into

    your display has a USB hub built into it, so you can plug the monitor into the USB adapter if you want.

    you can probably also find a dock / dongle that will have USB and display port on it, so only one cable to the computer, and then your monitor and camera would go into the proper holes on the dock.
    this will probably be more expensive, the small adapters are typically under $10.

    So I could I plug the webcam into the Dell monitor via the Webcam's USB-A cable, and then plug the monitor into my MBP via USB-A to USB-C cable? Will both the monitor and webcam work just fine in this scenario?

    thanks!

    You'd need 2 cables between the computer and monitor, 1 for the Display Port connection, and 1 for the usb hub.
