I just bought the dell U2713HM, which has 2560X1440 native resolution. I am using a late 2012 Mac Mini. I am using the DVI port in the monitor (which supports this resolution), the dual-link DVI cable that came with the monitor, the Apple DVI-D to Mini Display port adaptor, and plugging it into the MDP on my Mac Mini. The only thing I can think of is that the Apple adaptor does not support 2560 X 1440. Is that the reason why? Do I need to buy a display port to mini display port cable instead?
