Hi there. I have the same problem!!! I am fliyng with 4 monitors, 3 on VC and 1 on 2d. Iff i put the main captin view, it freezes!!! I use at this moment the zoomed du with the display with the route, and can't not use the primary flight display, Only one is free to use. To sorve the proble i use the standby atitude, and it works fine. But is not the same. Is it possible to fix this problem? Thank's Paulo Marques
