Hi Rick,
You can crop the output to HD or you if you have the right equipment hookup, monitor the entire 2K 2048×1556 frame without the need to crop on a 30″ monitor.
The hookup will be:
HD EXtreme -> HDLink Pro -> Dell / Apple / HP 30″ display
This will allow full 2K monitoring at full 23.98,24 and 25 frame rate at 2048×1556. Why crop when you can see everything 🙂
