OK.I have an FSX with PMDG 747-400. WINDOW 7. The PFD (primary Flight Display ) and the ND (Navigational Display ) are the only two that I can not put in one of the monitor. I am using six monitor. Three for the hole scenery and the rest for instruments. The cockpit has Saitek yoke, throttles ,Radios ,gears up/down and also AFDS Mode Control Panel. Is this sufficient information? Thanks
