Displaying your Widget on a big screen or display is simple to set up, just follow one of the below options.

I have one computer for control and one for display
Use one computer/device to control your product (set content, filters, moderate etc) and one computer dedicated to outputting the Widget. This is the recommended set up for a single screen output as it minimises complexity.

I only have one computer

This method relies on the computer having a secondary monitor connected and being capable of using the main screen while the secondary screen is in "Full Screen" mode. This is not the recommended method due to the complexity and possibility of your output being interrupted.

This method will not work with Apple OS X10.8 Mountain Lion due to the way the main screen is obscured while in "Full Screen" mode. OS X10.9 Mavericks will work with this method.
