Displayscope enables to use apps on out of sight screens such as display emulators, display dummy plugs and behind screens.

Displayscope has two use cases.

The screen sharing in remote meetings is consume one display for just the screen sharing (e.g. slide show, demo using entire screen, etc). In that case, you can get an emulated display by the display emulators/display dummy plugs, but it's can't see and can't control.

Displayscope provides view and control through the window to the emulated display. You can save a physical display for other purpose by using the emulated display for the screen sharing.

Some time there are no preview screen in onsite presentations.

Displayscope provides view and control through the window to the screen. You can demo naturally through Displayscope even if the screen is at behind you.
