Captain's primary displays cannot be undocked

Recommended Posts

With the latest releases, the captain's primary display can no longer be undocked (and moved to another screen).

This occurs with the 737, 747 and 777 so  I guess it was intentional.

It kinda broke my sim rig because I move the 2 captain's displays to a separate screen.

The workaround is to use the co-pilot's display, but it still leaves me to wonder (and hope we don't lose that as well one day).....

Why was this changed ??

  • P3D Captain PFD pop-up CTD protection has been added to all three product lines.  Since we have been unsuccessful in our efforts to convince Lockheed Martin to evaluate this CTD seriously, we have locked out the ability to use the CA's PFD as a pop-up display, but we included an option in the PMDG Options menu within the FMS that allows the user to Opt-In to having this popup work.  (NOTE:  This particular CTD, for those who do not know, affects a small percentage of users who use the CA PFD as a popup, but the CTD doesn't happen until you have been flying somewhere between 3-8 hours of actual elapsed time.  This CTD began to appear in P3D v3.1 after Lockheed Martin pushed that update- and no root cause has been found after literally thousands of hours of tests internally at PMDG- so we took this step in order to minimize the number of customers affected by it without realizing the cause...

Enjoy your weekend, everyone!

 I think this should explain your question.

I found the option to re-enable the undocking under "Simulation" in the PMDG Setup on the CDU.
