I recently discovered that my laptop's USB Type C port doesn't support display so I'm looking to get an external graphics adapter that will add a 3rd monitor for me (I have an HDMI port but nothing else for video).

I saw some on Amazon, but don't know if they support Ubuntu. My laptop has USB 3 so I'm looking for an adapter that uses that as it has more speed to it.

in case you're curious about the laptop in question its a ASUS VivoBook Pro 17 N705UQ

  • What laptop do you have? How does the USB-C port not work?

  • Also, do you have a docking station?

  • I don't have a docking station, don't want one, I just want the hdmi connection. The USB Type C apparently doesn't take in video on my model (ASUS Tech Support told me that this morning) so I'm going with the next best item

    Asus support is correct in that your USB-C port can't use an eGPU (only Thunderbolt 3 ports can do that), but mislead you in that it can output a video signal just fine. Here's one such cable.

I ended up buying this Multi Monitor Video Graphics Adapter* which wasn't working either until I disabled secure boot, curious to know if that prevented the other items I tried but I have what I wanted finally.
