How to get POA on external display / monitor, when Laptop is closed in docking station

Question

Hello, 
 
 The POA screen only appears on the laptop display. Not on a external display, that is connected via docking station. 
 
 It is a DELL Precision M4600, closed in a docking station with 2 external 22" Fujitsu displays. The Laptop has 2 graphic cards. Intel onboard an Nvidia quadro 1000M. 
 Until now, i disabled NVIDIA Optimus in Bios. ( https://de.wikipedia.org/wiki/Nvidia_Optimus) 
 And a tried the Shift F4 graphic toggle short cut at POA. 
 Nothing solved the problem. 
 
 Thanks for your answers!

Hi Reinhard, 
 You can accomplish this requirement by changing your display settings, you can change the priority of the display from the laptop screen to the external screen, please refer to article How to change the primary monitor . The other way of doing it is mirroring the screen, but I guess that won't serve the purpose of having an external monitor.
