How can I switch the positions of the main monitor and second monitor?
1. My Main monitor is 30" Apple Cinema Display
2. Samsung 22" Syncmaster
I was using the ACD with the DVI-D connection and it was my main monitor where I had the dock and everything. Then when I connected the Samsung Syncmaster with DVI-D+Mini DisplayPort, it became the main monitor and I can´t have that!
I can´t seem to find a button where to switch these positions. I even tried to switch the cables, but then I couldn´t get the 2560x1600 resolution to ACD.
My Last Mac Pro worked perfectly because it didn´t have those annoying Mini DisplayPorts.
