I've had my MBP for about 2 weeks now and love it (my first Mac!!). About a week ago, I was poking around the system preferences tab (I don't remember which sub-topic), but all of the sudden my screen and attached monitor went to 256 color mode. I checked the display settings, and it said that both screens were in "millions of colors" mode, and rebooting didn't fix the problem. I figured I would try unplugging the monitor, and, voila, it went back to normal. Now, every time I reboot my MBP, it goes to 256 color mode until either: 1. If the monitor is plugged in, I have to remove and reinsert the DVI cable from the MBP 2. If it's just the laptop, I have to insert and remove the DVI cable. This really sounds like a driver or configuration problem to me, but for the life of me, I can't figure it out. I've tried clearing my PRAM, but that doesn't help either. I figured I would ask for help here before making the trek to the Apple store. Any tips are greatly appreciated!!
