I'm using MSFSX with Win 7,64 bit OS for B767 Level D simulation, using multiple Monitors for Display.
Using Matrox digital card I'm not able to get main panel display for pilot and copilot side on dual monitors. On selection to main panel it only displays pilot side panel by default. if I select B767 main panel FO the pilot side main panel becomes FO main panel and pilot side main panel display goes blank.
I'm just guessing (never used dual monitors) but I can't see how you can undock the panel from one monitor and expect it to be on two monitors.
Only one per customer is what I'm getting at.
