MPE will only tun on the card which is connected to the primary display.
Damn! I had a feeling it was like that. So in a dual monitor setup if I have a CUDA enabled card driving one display and a non cuda card driving the other will MPE work if i put just the program monitor in it and keep the rest in the other(non-CUDA) monitor?
Yes, but to get that to work well you will need two nVidia cards that use the same video driver.
Adobe detects for the MPE off the primary display. The Primary display has to be on the Nvidia card.
