Visiontek USB2.0 to DVI-I External Video Card

Comment:
This thing was easy to get running to give me a third display on my windows 7 machine, however the third display running through this adapter has a lot to be desired. Sometimes it fails to refresh, and applications will look like they are frozen. Also for some very strange reason Internet Explorer is incapable of displaying webpages on this display, while all other browsers work fine. Sometimes video works on this display, sometimes it doesn't. Finally it seems that this hardware has slowed down my computer in general, and introduced some new instabilities to windows that I've never seen before.Overall this was a very cheap solution to give me a third display, however you have to be patient with the numerous bugs that it might introduce to your system. It's usable, but not solid.
