I am using and App called DIGIVOTE® which requires or has an option to use in dual extended screen mode. I always run on dual screen on my MacBook with my Dock on my second screen. How do I replicate the PC in dual extended screen which enables me to run my app with a technicians control panel on my laptop and what is being sent to projector on my second screen (right click desktop/properties,settings/extend picture to second screen (ie not mirror)? We can also use this layout for PowerPoint as well with the drive screen on the laptop monitor and the projected image on the second monitor. Thank you
