The M92Z3327 AIO has 2 DisplayPorts 1 out and 1 IN. I have configured a Computer with a VGA output attached to the IN DisplayPort with a VGA to DisplayPort cable. When attempting to switch from PCMODE to MONITORMODE (via a console button) there is a momentary screen - "Now in Monitor Mode". The screen then goes black. Pressing the button then takes it back to PC Mode with a normal screen and operation. The system came with Windows 7 Pro and been upgraded to Windows 10.
