Is monitor working otherwise, seeing POST screen, works when you boot to command prompt? Just blanks out in Windows. Or have you got nothing at all when plugged to this card.

Since the monitor works on the on-board port, it's probably not a bad monitor or cable (I;m assuming you are using the same cable in both cases). Since the Dell LCD works on the graphics card, it's probably not a bad card.

I suspect it's some incompatible signalling ... perhaps resolution, refresh rate, sync polarity or any number of factors.
Graphics cards usually come with a setup/adjust tool that works with their drivers to adjust many aspects of the video signal.
Assuming you have this, you could take a look and see what it can adjust - you might have to "play a little".

Been so long since I worked seriously with W98 - does it support two monitors on two separate video interfaces?
If you could get such a setup working, it would make it a lot easier to "try things" without constantly having to lose video and move cables.

good luck!

Nothing at all. Just a blue box with white text that says "NO SIGNAL."

This sounds weird, but you can try the magic reset for confused digital detection CRTs... lick your thumb, wipe it so so it's just damp, then plant it firmly on the end of the VGA cable, pushing hard enough to contact all the pins... there are some theories that the digital circuits get hung up with static buildup or something... putting the one megohm approx thumb resistor across the pins to the shell bleeds it out.

The uncooperative monitor in question actually has a built-in, permanently attached VGA cable, if that makes any difference.

As for using two monitors on separate video interfaces with Windows 98, I believe (if my memory serves) I've looked it up before, and can recall discovering that you could. I'll have to check again, though.

Also, I'll definitely try what you suggested with the ATI control panel to see if that helps. Thanks for the support, man!

I'll have to try that. Thanks, man! As stated before, anything helps, no matter how seemingly outlandish!

Is the DELL monitor also using VGA? Or DVI?
