Please help I cant figure out why my black is doing this? I have checked all data cables, cant find anything wrong? If swapped the light magenta head and the black head had and its still the same? Black still going crazy.. The top pic is the cables plugged in normally, the middle is the black and light magenta data cables swapped at the head...and the bottom is the yellow and the black data cable changed at the head?? Still only black messing up? Please any help or ideas?
