🗨 About

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

🎯 Use cases

Displayscope has two use cases.

1. Dedicated display for screen sharing in remote meetings

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.

📃 Notes

• Displayscope prevents the screen from going to sleep during the external display showing. If you want to go to sleep on your PC, move back to the screen list view.

• Displayscope doesn't work correctly if you selected the High-performance NVIDIA processor as the Preferred graphics processor in the NVIDIA Control Panel. Auto-select and Integrated graphics are works well.

• The Displayscope's settings file located at %AppData%\Displayscope\settings.json. You can change the global shortcut keys through this file. See here for the acceptable shortcut key combination.
