External Monitor issues

[spasell]

I recently hooked up a HPw1907 display to my docking station. I ran all the software and it worked fine.

However, recently, when hooking up my x61T to the station, the resolution to the screen does not auto adjust any longer to the 1440 or TOP resolution and all the images look distorted and FAT.

I opened the presentation director (hitting F7 to do so when docked toggled between my monitor being off and on and the external monitor being shown) but cannot figure out how to make it automatically detect the external monitor (there's no option there to pick it).

Can someone explain what I might be doing wrong? I'm using Windows XP. Thanks for the help.
