Here's a good one.
Users laptop: Resolution is at desired level. Intermittently, resolution will increase to the highest possible setting. This occurs when the unit is being docked/undocked (using an external CRT monitor). It ALSO happens when the laptop is in its stand alone state and using only the laptop screen.
Windows 2000
IBM T41

Is there different hardware profiles set up for a Docked and an Undocked state?

Check the refresh rate of the monitor.  Usual settings are 60Mhz.

Make sure there is no dust blocking the vents.  Overheating could also be the problem.

Also, the onboard video card (chipset) could be dying.  Depending on the laptop, some come with an independent video card and can be replaced otherwise the entire motherboard has to be replaced.

Check the video drivers.  Make sure they are current.  Another trick I have used in the past is to remove the video drivers and set to standard VGA and restart.  Let the laptop reinstall the drivers and see if it helps.

So far we have narrowed it down to possible faulty video drivers or a bad ISO OS install. We're checking both at this time. The laptop alters its resolution whether it is docked or undocked and with flat screen and CRT's.

We rolled back to a previous ISO and this corrected the issue. Apparently two of the three ISO's contained video drivers for Dell and not the require IBM. Thanks to you all for your help. David
