We display to multiple screens via a VGA splitter, and this generally works well. However, occasionally due to either operator error in setting up the displays or accidental disconnection of a cable during the service, the display comes onto the laptop monitor obscuring the control screen. Sometimes pressing "Esc" will bring back the control screen enabling us to recover the situation ; but frequently we are stuck with the display on the laptop monitor with no alternative but to shut down and restart the computer. Ctrl-Alt-Del starts the Task Manager but that too is hidden behind the display, likewise Alt-Tab won't give access to anything else. I can bring up the taskbar and click on Close window for OpenLp but that doesn't do anything. same symptoms in both Windows 8 and 10.
Is there any easier way of recovering from this situation other than a complete restart ? Any keyboard shortcut for example that will close OpenLP ?
