Multiple monitors on ZBook

[GALJohnson]

"Having trouble getting more than 2 monitors to work on my ZBook. Found this article from HP. It says 

Tip: A quick way to enable all displays connected (up to the maximum supported) in extended desktop mode is to use Windows presentation key and choose “Extend” mode. 1) Connect displays; 2) Press Windows logo key + P; 3) Select Extend."

Google brings up nothing to the search phrase "Windows presentation key". I have not been able to find any reference to it anywhere.

Thanks for any help anyone can give!

This laptop is supposed to support up to 4 screens as it stands, including the internal display. I have been able to get to external monitors working on the display port and on the VGA port,  but not at the same time. The internal screen has worked with both of the listed ports but not at the same time. I haven't tried the thunderbolt port because I don't have a thunderbolt capable monitor and cable.  I think that myh original question may hold the key to my issue.p

I'm not really interested in buying more equipment when what I have is supposed to be able to do considerably more than  what I am looking for.
