2D cockpit and VC showing instruments at the same time

hello, I am running 6 screens on the same computer on a I7 2600K eyefinity and matrox on same video card. My question is : I want to use the PMDG 737 NGX on EYEFINITY TOP SCREENS.Then I want to show 2D cockpits panel on the 3 lower screen (generic setup).On some of the Addon i own it works....on some other it won't.i was told by a friend that pmdg 737NGX will only show it's PFD and ND... either on the 2D cockpit or virtual cockpit but not both at same time.Anything could be done about this? Best regards
