The screen capture device can be used to capture a particular monitor/desktop, converting the captured frames into a video data stream. Note: the Screen Capture device will only start capturing frames when a valid sync signal is sending data to the 'Sync' connection. Every time a sync signal is received, the screen is captured and a new frame of video is created. Usually, a Builtin.SyncGenerator would be used to provide the sync signal, thereby allowing the unit to operate at any desired FPS. Note - capturing the screen is a relatively expensive task. Attempting to use a frame rate that is too high can result in frames being dropped.
