I have a 1 month old macbook 2.0g running 10.5.2 and am having difficulty understanding running out into VGA monitors. I'm using the mini DVI to VGA adaptor and I get a picture ... but it's the wrong scale. It seems to reset the screen on the laptop as well. I have run into a bunch of different monitors and some projectors ... all with the same result. How do I re-scale to fit?
