I've hit a wall trying to connect a PVM-1450QM Sony monitor to my iMac. I'm using an sdi to vga cable that I connect to the computer with a vga to mini displayport adapter. The computer recognised a second monitor but the smallest resolution option I'm getting is 800x600, meaning I had to create a custom one with SwitchresX. Something obviously went wrong and crashed the OS and continues to do so even after removing the app and it's system pane/preferences.
Am I even able to get the right resolution set up for the monitor and therefore making this dual display work?
