Hi all. I have a late 2009 Macbook Pro 13" with a mini display port. I am trying to connect it to my Samsung Syncmaster 731BF. To get that done i bought a mini displayport to DVI adapter. Now i want to mention that my Samsung monitor only has a VGA cable but i've been connecting it to my gaming desktop's EVGA graphics card via a DVI converter (successfully). So currently what i'm doing to connect it to my Macbook Pro is this:- mini displayport-->dvi converter-->vga cable on samsung Now it does not work ('check signal cable' box) and i'm confused as the same monitor works with my gaming desktop where the dvi converter was utilized as well. Thanks folks!
