Hi All, I have a Power Macintosh 8100/100 here, and I have an IBM G40 PC Monitor attached on it by an adapter... It's really working, but on a low 640x480 resolution screen... This monitor works on other PCs with full 800x600 or 1024x768 resolutions... How can I change this on the 8100? P.S.: On the screen icon on the dock only apears 640x480 67Hz... Thank you all!
