Parallels V 4.0, Macbook Pro (15.4", aluminum), Windows Vista Ultimate, Apple 24" LCD external (LED backlit). When I initially connect my Macbook Pro to my Apple 24" external LCD, the resolution on the LCD is correctly set to 1920 X 1200. However, when I boot to Windows Vista in the VM, the resolution is set to 1440 X 900 IF that was the last resolution that I booted to instead of recognizing that the external LCD is 1920 X 1200. If I later boot without being connected to the external LCD, the resolution in the VM is still set to 1920 X 1200 and I have to change it to 1440 X 900. Any solution to this problem or do I have to continue to change the resolution manually? As I recall, in Parallels V 3.0 (latest build), I did not encounter this problem.
