Try "zapping" the PRAM, this will force the video card to query the connected display and you should see an image. Hold down the keys command+option+P+R at startup until you hear the Mac chime at least twice before you let go; if you don't hear chimes, watch the VGA monitor's indicator lamp which should show active when it first detects a signal, then inactive as it begins or fails to synch, let it cycle a few times. Clearing the PRAM is a good precaution anytime you are tinkering with hardware, as it forces the Mac to forget what it thought it knew about itself. If a PRAM zap doesn't help, connect a different display - I have had this problem mostly on really cheap or very old displays that are not properly following VGA standards. As a last resort, if you are a veteran Mac user you may have some video adapters to connect VGA equipment with older Macs & Apple displays: try putting a VGA-to-Mac adapter in series with a Mac-to-VGA adapter. (And if you think only Apple gear has this issue, then you never tried to fix a video synch problem in Windows - why do you think Safe Mode is 640x480?)
