KVM Switch for Apple Macbook Pro and PC

Hello All!!

I am looking for your advice and help!!!

To get to the point, I am trying to connect my Macbook Pro which has Mini display port OUT and my PC desktop which has DVI and HDMI OUT, to my Apple Cinema display 27 in aluminum, bought around 2008, so I know it does not have thunderbolt.

Currently I actually use my Apple Cinema display connected via a DVI adapter to my PC Desktop. I use the adapter made my Atlona AT-DP400 works great

So basically, I want to be able to switch between my Macbook and Desktop PC with the switch, using the Apple Cinema display.

What do I need!!!

Thanks!!
