Driver-based external LCD problem with Sony SZ series

[Doc. Caliban]

I have a Sony VGN-SZ340P with a Go 7400 GPU.

When I bought the laptop, the first thing I did was to format it and do a clean install of XP. I loaded all of the 'official' drivers from the Sony download site, including their supplied 7400 driver. With this driver I cannot use my Samsung 244T display (1920x1200). I can, however, use a basic 17" Dell LCD (1280x1024).

The next thing I did was to download a driver from LaptopVideo2Go, though I don't remember which one, and install it. I was then able to use the Samsung.

I have recently formatter the machine again and reinstalled everything. However, I cannot get the Samsung to work again. I don't want to try drivers blindly, so the only one I've tried so far is the official 84.63 driver from nvidia.com. When I try to install it, it tells me that it can't find a compatible GPU. Since the drivers are for the mobile GPU's, I figure it has something to do with the Sony OEM or something. I downloaded the modified inf from this site and used it to get the official nvidia drivers to install. I am still not able to use the Samsung.

In short, I need to find out which driver will allow me to use the Samsung LCD.

Ideas?

Thanks for your time,

EDIT:

I've attached my NERD log file.

Also, I've noticed that while the laptop does in fact recognize that the monitor is there, it reduces the color depth to 16-bit if I set the resolution to 1920x1200. (Not that it ever send a signal to the monitor in the first place.) Again, this must be driver related because I ran this monitor if full-res @32-bit with this laptop for a few months with a different driver.
