Question for wendell about his computer & monitor setup

In your video How To Virtualize All the Things we saw a glimpse of the other side of your monitor setup.

  • How are you using a single image for your background and having it continue onto all of your monitors? I've tried to use some software in the past but none of it actually worked like I wanted. Sorry if this is a feature in Windows 8, I still haven't upgraded.
  • What GPU is powering that rig?
  • What resolution are the monitors? 1920x1080 or larger and are they mis-matched sizes?
