Can't get monitor to go back to native resolution. Samsung syncmaster 206BW

Monitor is Samsung Syncmaster 206BW.  Native resolution is 1650X1050.  I run this monitor off of my laptop docking station.  Upon initial install, everything was fine.  Then I took laptop home and showed a movie for my kids on our projector.  Now I can't get it back.  I've tried uninstalling and reinstalling drivers nothing works.  I've looked all over Samsung's website but couldn't find anything.  It may be there, but I'm not really sure what is going on.  I did have to mess around with the display settings when I used the projector because the new monitor had messed up my Fn+F7 display settings.  The kids were growing impatient and I hurried through changing things around until the projector was finally recognized as the external source.  Now when I try to set my Samsung monitor back to 1650X1050 it makes the display larger than the actual screen.  The screen will slide over when I mouse over to the sections I can't see but of course that is not the solution.  Any ideas on what I need to do?  What I might have messed up and how I need to set my Fn+F7 settings so that this doesn't happen again becuase I use the projector fairly often.  The main 3 configurations I need are laptop screen only, laptop (open) to Projector (VGA to DVI and resolution of 1024x768), and docked laptop, closed, with DVI to DVI to Samsung.  Thanks in advance for any solutions you have.

One bit of info I left out that could be the cause.  When I set up originally it was with VGA to VGA connection because I didn't happen to have a spare DVI cable laying around.  When I went back, I used the DVI to DVI connection that I had purchased.  It can't be the orginal setup because I redid it all.

Your problem is either in the settings for the TV output (maybe you disabled sensing the connection?) or in what it thinks the second display is.  The first will be in the TV out section of the display properties and the second is best checked by looking in the device manager and what driver is being used.

I'll check the TV out settings but I have gotten the Samsung to be listed as #1 and #2 monitors when I press identify under display settings.  It responds the same either way.  But I will check TV out settings.  I don't remember doing that.....could be the answer.  I have double checked the driver and it's the right one.

Still working on this.  I've tried everything I know.  I need help.  I've uninstalled and reinstalled the drivers again.  Still no luck.  Help!

One, very annoying habit in Windows is that you can reinstall til you are blue in the face and the settings you have changed stay that way; not deleted on an uninstall and still there after the re.
Another common checkbox in video drivers is a "virtual desktop", AKA desktop panning.  This allows users to craete a desktop much larger than their display and scroll around.  Check it and, si we can really help you, what is the laptop and what display adapter does it have in it?

My laptop is about 3 years old and doesn't have the greatest card although for it's age it's not bad.  I've got an IBM Thinkpad T42 with an ATI Mobility Radeon 7500 with 2005 ATI driver.  I had an omega driver installed but for some reason it will not allow me to reinstall.  It was somewhat better for  the laptop display but external higher res applications it would just black out the display so I haven't really worried to much about it.

Way down this page are brand new drivers for the Thinkpad http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-55386
Download them, uninstall the current ones, and install these.
