2 displays on mac mini late 2012 with 2560 x 1440 Pixel each
Is it possible to connect two Displays with 2560 x 1440 Pixel each to a mac mini without using thunderbolt? I already us a Dell U2713 Display with this resolution connected via mini display port. I'd now like to add a second display, if possible another U2713, to extend my desktop. Using HDMI offers only 1920x1080 for the second display, the displayport adapters/splitters seem to have the same restrictions.
Mac mini, OS X Mountain Lion (10.8.3)
