How to use

Run the app.
Set options (resolution etc.) and enable the virtual screen.
Go to VNC tab and then start the VNC server.
Run your favorite VNC client app on your second device and connect it to the IP address appeared on the app.

CLI-only option

You can run VirtScreen with virtscreen (or ./VirtScreen.AppImage if you use the AppImage package) with additional arguments.

usage: virtscreen [-h] [--auto] [--left] [--right] [--above] [--below]

Make your iPad/tablet/computer as a secondary monitor on Linux.

You can start VirtScreen in the following two modes:

 - GUI mode: A system tray icon will appear when no argument passed.
          You need to use this first to configure a virtual screen.
 - CLI mode: After configured the virtual screen, you can start VirtScreen
          in CLI mode if you do not want a GUI, by passing any arguments

optional arguments:
  -h, --help       show this help message and exit
  --auto           create a virtual screen automatically using previous
                   settings (from both GUI mode and CLI mode)
  --left           a virtual screen will be created left to the primary
                   monitor
  --right          right to the primary monitor
  --above, --up    above the primary monitor
  --below, --down  below the primary monitor
  --portrait       Portrait mode. Width and height of the screen are swapped
  --hidpi          HiDPI mode. Width and height are doubled

example:
virtscreen  # GUI mode. You need to use this first
            # to configure the screen
virtscreen --auto       # CLI mode. Scrren will be created using previous
                        #   settings (from both GUI mode and CLI mode)
virtscreen --left    # CLI mode. On the left to the primary monitor
virtscreen --below   # CLI mode. Below the primary monitor.
virtscreen --below --portrait           # Below, and portrait mode.
virtscreen --below --portrait  --hipdi  # Below, portrait, HiDPI mode.
