Update:

To reset the Hz settings on my PC I had to choose the Adapter tab.

I have had this monitor for almost 3 years.  I tried everything that this
group suggested with no success, so I called Dell.  The person I spoke with
waited while I switched monitors and I had the same problem with a different
monitor.  Then he had me do several tests and it was determined that I have
a bad video card.

Thanks to everyone for their responses.

Debbie

To reset the Hz settings, right click on the desktop
in an unused area, choose properties. Click on the
advanced... button and then choose the monitor tab at
the top of the window. You can then use the drop down
arrow to change this setting. Here at work we use the
60Hz setting. Sometimes this will help prolong the
fact that your P-991 is going out. With over 100 Dell
monitors here we loose one of the older P991's every 4
months or so once they are 3 or more years old. Hope
this helps...start saving for a LCD monitor.
