Two monitors - how do I maintain my extention settings?

I am running XP Pro (Service Pack 2). I have a Dell Latitude D820 with 2 GHz and 2GB RAM. I have no problem setting my computer to the settings I want while extending to the second screen (a 24" Samsung 1920 x 1200). My problem lies with going from user to user or when the system goes to sleep. I have to continually reset the extended screen settings. How do I lock them in?

Note that this problem is recent. It used to stay at the correct settings, but now it doesn't.

 

How do I uninstall the video card?

PeteC, Thanks for the reply. How do I reinstall the video card. Should I go to the "Device Manager" and uninstall the "NVIDIA Quadro NVS 110M" card and then restart the machine? Or is there some other way?

 

PeteC,

Thanks for your comment. The problem seems to be cured, although I'm not sure how. I uninstalled the hardware. When uninstalling the hardware, it asked me if I should also delete the software. Then came a message asking if I should delete the registers. I said yes to both. Upon rebooting, I had to reset the screen, but the hardware and software (drivers) seems to reinstall themselves without me doing anything. And it seems to work just fine now for all users. Thanks for your help.

 

PeteC,

Interesting followup problem. Though my screen resolution problems are gone, I seem so have inherited a new problem. My capability to "hibernate" seems to have disappeared where before I used it often. In fact, my current screens says it is not even there. My machine now also doesn't go to sleep when I shut the screen like it did in the past. What did I delete and how do I get it back?

 

PeteC, That's my problem. The hibernate tab is NO LONGER THERE! I have nothing to check or uncheck. That's why I'm so puzzled. (By the way, thanks for the continued support).

 

May want to double check BIOS for Power Management settings.
