Your post is a little confusing but since it's not working on the laptops and you said: "I tried the monitor on another computer but no dice, it didnt work.", then aren't you saying the monitor simply doesn't work? If that's the case, try a KNOWN GOOD monitor. Our Acer monitors seem to die fairly regularly..

If you've got a known good monitor, then access the graphics card display options in the Control Panel.

Hope this helps.
