Need help with new monitor

[bige321786]

I use a Dell Inspiron 8500 notebook. It works perfectly. I decided I wanted a new monitor because I was tired of multi-tabling on my laptop's small screen. I purchased the Dell 2407WFP-HC 24" and connected it to my computer and it works just fine. I just have a few questions:

The monitor recommends running at 1920 x 1200. I use the nVidea GeForce4 4200 Go video card that my laptop came with and the highest resolution I can set my laptop to is 1680 x 1050, which is what I currently have it set on. The CD that came with the monitor recommended I upgrade my video card's drivers to hopefully be able to use the monitor at it's optimal resolution.

I downloaded the current patch from nVidea's Web site but when I go to install it, an error message comes up, telling me the installation cannot find the necessary hardware on my computer to continue with installation. I am sure of the exact video card I have and I am positive I downloaded the correct patch. Any suggestions on where to go from here?
I have one further question. I"m hoping this one has an easy fix.

When I open a video program and begin to play a video (Windows Media Player and InterVideo WinDVD) the video is immediately and automatically presented in full screen on my large monitor and the regular laptop screen shows a "normal" setup (open program, desktop on the background, start menu at the bottom, etc.). I am unable to get the full screen video off my large monitor without closing the program enirely on my laptop screen. I want to be able to watch videos and run other applications on my new monitor. Any suggestions would be very helpful. Thank you.
