Had planned as a second connection to a mini adapter. The picture is extremely pixelated at the edges. In the areas to lively, psychedelic pattern form of individual different bright spots. It is not on the screen, the cable, the Resolution (native 1920 x 1200, everything else the same). Sure, it might still be the Mini DisplayPort adapter to the Mini over, but is unlikely and I can not test for lack of a second adapter. So either defective or a lousy solution.
