After my Dell laptop's battery kicked the bucket a few days ago, I used the failure as an excuse to go out and buy one of the new Macbooks. I bought the lower-end new MB for $1299. I got an adapter to use DVI to hook up my MB to a Dell S2409W monitor that I bought a few months ago. When I hooked up the monitor, however, there was a random pattern of flashing red pixels; it looked like some sort of red static. When I shut my MB, there is significantly less static, but a few red pixels pop up from time to time. Is my MB capable of running 1920x1080? Do I have a problem with the GPU in my laptop? Is there something else going on? From talking to the people at the Apple store, it sounded like I wouldn't have any problems running a 24" external monitor at 1920x1080, and AppleCare said it's probably a compatibility issue, but I don't know how that would explain the difference between running both screens and just the monitor.
