I ordered a VGA cable and a minidisplayport to VGA adapter from ebay, and my lcd keeps saying no signal when I plug in all the cables. I am at a loss as to how to get this to work. The MBP won't detect any external displays. Any thoughts? Edit: I'm running 10.6.2; Also, the ebay seller (http://myworld.ebay.com/jinbostore) is in China, so I really don't want to go through the hassle of sending it back unless I absolutely have to.
