Ok, I bought the mini-display port to dual link dvi adaptor for $99. However, it doesn't work from going from my pc to the imac or from my macbook pro to the imac. I find it retarded that they wouldn't even sell a working adapter. Has anyone gotten this to work or does anyone know which adapter I can buy to get this going? Again. -PC to iMac -2009 (pre-minidisplay port) dvi to imac. I need it to be dual link dvi because I want to use it at max resolution. Thanks in advance.
