Hey everyone, Just a quick troubleshooting question. I have been using a 20" Acer monitor as an external display with my Macbook Core Duo 1.83. For the last 12 months it was working great; BUT, I just turned the computer on and in the displays pane I can only increase the resolution to 1600x1200 now, so the screen looks stretched. Does anyone know how this problem can be fixed? Thanks Edit: I was just looking at my iStat Pro and noticed that 1.34gb of the RAM is 'inactive', does this have anything to do with the resolution limit?
