Laptop resolution changes by itself

I have a Dell Latitude d800 laptop. Recently, the hard drive needed to be replaced. Everything works fine, except for the resolution. When I dock it, the resolution automatically changes itself. I can set it back and it is fine. When I undock it and boot it up, it is fine. But, when I put it back in the docking station, it changes it's resolution again.
I have updated the video driver. I can't for the life of me figure this one out. I tried deleting both hardware profiles, but the problem persists.
I spent an hour on the phone with Dell and they eventually sent me a replacement video card. I installed that, but it still does the same thing.
Any ideas?

you've defniately hit on what I would have with updating the video driver and deleting the docking profile. Did you get the updated video driver from dell's site? Is there a monitor connected to your docking station?

You might have the display properties set to "clone". External LCD monitors very often have a much lower resolution than those of the Laptop itself. If the setting is set to clone, the lower resolution of the 2 displays will take precedence. Use some other setting for the second monitor and then the laptop's LCD should keep it's resolution.

I don't see the "clone" option anywhere in display properties. Where would I find that?
