I try video card and other product that claim to do what this one do , but none of they work . the StarTech USB\/VGA adapter be easy to load\/setup , and once activate I have both monitor show what I need in 5 minute . this unit work great , and I be recommend it to anyone who need to run a `` two screen '' application of any sort . I be run pro tools and need to split the screen so I can follow all the application without have to constantly close this , minimize that , etc. .
