So i'm using my Early 2008 MacBook Pro still despite it falling apart and being held together with some homemade repairs (hey it works ppl). But I am primarily using my new Lenovo y510p for web work and designing. I use it as my primary work source, so I'm looking for a way to hook my macbook early 08 up to use as a second monitor for my Lenovo y510p to be used as the main source for working. I have the DVI VGA converter (http://i.stack.imgur.com/hP5dV.jpg) but dont know if this will help. Any suggestions or cables that will help me accomplish this? Links to products would be most appreciated if possible. Thanks!
