Hi, I have an older Dell 3007 30 inch monitor. When I plug it into my 2010 MBP via a monoprice dual link dvi - which needs a USB port for power and a display port cable, then it works fine and I can set the monitor to it's native 2560x1600 resolution. When I plug the 2 cables into my new Retina MBP the highest mode it lets me select for the dell is 1600x1000. Has anyone seen this before? Is there a way to get this working with the retina MBP? My retina is running Mountain Lion with all the updates applied. Thanks!
