I'm the guy wanting to hook a Compaq 140 VGA monitor to my Mac G3 266 desktop running OS 9.2.2 w/ a Mac VGA adapter. I've gotten many good suggestions including changing the pin settings on the adapter. I may not have been clear on my original post but I can't adjust monitor Control Panel, or any other settings because I have a blank screen and can't get past that part. I did a "google" trying to find the correct pin settings but couldn't find that. It may not be a multi-sync monitor. I'll check into that. Anymore suggestions, I'll hear them but thanks for all your contributions. Ron/TN
