I have had this issue as well when i use vista on my mac via bootcamp. I had to go into the hardware settings to and mess with the way the computer uses the monitor. look through the OS settings and the graphics settings to see if you could get it working. if you mess around with is a little while you should be able to add that monitor as a second screen instead of its own screen.
Thanks for your reply! First one ever! I am kind of surprised that no one from Intel monitors these groups and helps respond.
I am thinking I have dug pretty much through every permutation of settings, even looking at BIOS settings, but all to no avail. but it sure seems strange that you cannot do this.
But thanks again!!!!
