Works pretty much as advertised.I'm using it to run a third monitor because my work computer was maxed out at two, and it has no room for expansion internally.I'm running a 19" LCD at 1280x24x32 bit color. It gets a little choked up with moving images, at least at the resolution I'm running, hence the four stars. I would definitely not use this for a primary display, but it works well enough for a secondary display.And contrary to what others may post, it works with Vista (x64 included). The drivers are on IOGear's website.
