MAC G3 video problem

Not MAC savy. I demonstrated to a user how to change resolutions on a MAC G3 tower using OS 9.2; NEC 17 monitor. A few minutes later, the person came back and said the monitor stopped working. Apparently, the user tried out higher resolutions and the monitor went black. I tried the following to no avail. Zapped PRAM, deleted systems and monitor settings (reboot). I can boot using install CD or without any extensions. I can also attach a high end Sony Flat 20" TFT monitor which works, how do I get the NEC 17" monitor to work again with the G3. Thanks in advance.

Er...why not just change the display to a lower resolution while the machine is attached to the big monitor? Should work fine when you put it back on the other one then.

Right. If you've lowered the resolution and the monitor won't work, I'd say the monitor cooked.

Clarification: when I had it connected to the TFT screen, I set resolution to 800x600 in Generic RGB mode, buth when I reconnected NEC 17", it goes black on startup. I've Zapped PRAM again AND pulled battery to reset entire machine. Still no monitor

I have two thoughts on this.

1) Coincidence. The monitor just happened to die at the wrong time.

2) She wasnt using the recommended list of resolutions and went to a frequency that the monitor just couldnt handle. Poof.

FIX: Delete all monitor and colorsync preferences. Zap PRAM and rebuild desktop to bring monitor back from the dead. The Last option would have been to re-install OS. Thanks for all the feedback
