Just set up new computer with dual monitors. When I undock the program sequence pane and move to second monitor, the audio plays, but video doesn't play. If I drag the pane so part of it is still on the first monitor, it plays and the part that is on the second monitor plays as well. But video doesn't play if the entire pane is on the second monitor. Is there a setting I'm missing somewhere?
In the OS, how are your dual monitors set up, please?
It may be your video card/driver? What card do you have and which driver version do you use? How did you setup your dual displays?
