There is a doubt in my mind Will using an usb to vga adapter connect my macbook pro to my 2006 imac. I have a spare old imac of my brother. So i wanted to connect it up too my macbook pro for a spare screen when editing, but i need some way to connect my monitor to my laptop so would a usb to vga adapter work? If someone has connected it like this then please tells that how can I do this? Thanks.
