: Apple Mini-DVI adapter not working with DVI Extenders - Fixed
My edit suite runs two 25' DVI extenders, VERY heavy duty extenders that were about $120 each. This suite has run with the G5 Quad 2.5, the Mac Pro Quad 3.0 and the Mac Pro Octo 3.2 with zero issues running two DVI monitors and the extenders.
Now I get the $7,000 top of the line Apple Octo Core machine with the ATI 4870 graphics card which of course Apple mandates with one regular DVI port and one Mini DVI port. I got the adapter that allows me to run two standard DVI monitors. The one connected to the Mini DVI port is not coming on. We even switched the cables in the back of the machine and only the regular DVI port is putting out an image to the monitors.
Now we're going to have to come up with another workaround. If you have a "special monitor" (i.e. Apple LED Display) that requires a "special DVI port" because you don't want to pay the licensing fees for regular DVI, why don't you create an adapter cable the OTHER way around? Regular DVI to the Mini DVI required by the Apple monitor?
