Packard Bell 15" TFT distorted/shaky image

Hi,

I have attached a Packard Bell 15" TFT monitor to my PC
running under Windows XP. The image is not steady and
quite distorted. It works fine when attached to my other
PC which runs under Windows 2000 pro. I reattached it to
the 2000 pc with the intention of copying the driver over
to my XP PC but device manager says there is no driver for
the device (it sees it as a plug & play device).

Any advice would be most appreciated.

Thanks,

Stuart
