Hello, Ever since switching from my Powerbook to my MBP, I've noticed that when I'm rebooting, when the white screen comes up it sits for a good 2-3 minutes before showing the gray Apple logo at which point the system boots at normal speed. This waiting time on the white screen does not occur when using the MBP without the ACD. My ACD is the older generation (with plastic trim) in 20" and has always worked fine, however, it seems that when running with my MPB (closed-lid) it adds some extra lag time during reboots. Anyone else experience this? I've also seen some issues occuring when I open the lid, while connected to the ACD, it seems to lag where as with the Powerbook, it'd immediately realized that is should span the display across the ACD to the powerbook. Seems as if the MBP is stupid when it comes to handling dual displays with an ACD... Thanks!
