title: USB-connected external graphics card
body: <p>Is there any way in any Linux-based OS to access the instructions sent to have it transfer the instructions meant for the GPU to an external device connected via USB3.0 (and, obviously get the pixel output back)?
  In Windows there is no native support for this kind of thing. Although many external graphics card exist which connect to a PCi slot, I didn't come across any USB ones.
  Is there any way to accomplish this with native support of any of the Linux OSes?</p>
  
  <p>EDIT: I was misunderstood, as far as I can see the comments. I want to program an external graphics card, I'm just looking for a way to get the GPU instructions to get to my device and get back the pixel array.</p>
