The only information I can dig up on this is that it supposedly worked in Boot Camp 1.4... I have a MacBook Pro Core Duo. I installed Windows XP on it through Boot Camp. I updated the drivers to the Boot Camp 2.1 package and downloaded Service Pack 3. I am not having any luck in getting a VGA monitor I have hooked up to the MacBook Pro using the proper adapter to work. Under Displays, the second monitor is detected. When I change the resolution, nothing happens. When I do extended desktop, my cursor is able to go to the right side of the screen, but still nothing. The only time I got the display to work is during boot up. Oddly when the Windows startup screen and status bar are going on after powering up, that image is mirrored to my display. Afterwards the display goes blank. It doesn't have the Check Signal Cable screen, but the screen is blank. I tried the ATI Catalyst Control Center and drivers, but the CCC complains about a MOM.exe (I believe) is missing or not working. I tried the Boot Camp and regular Windows XP versions. At one point, I think I erased the Apple drivers, so the monitor worked, but I got no hardware acceleration, was limited to 1280 x 1024, and the MacBook Pro display was off. The Device Manager recognized it as a VGA adapter missing drivers. So, do the VGA adapters just not work in Boot Camp or am I doing something wrong?
