custom monitor driver

i need a monitor driver for future power 19db05. running on windows 2000. the monitor support high refresh rates. however windows detects it as a plug and play monitor. And only allowes it to goto 100hz @1024x768. I need a driver to make it run at 120hz refresh rate at 1024x768. I need the driver file to make windows run on 120hz with out any tweaking. It must show 120hz when you click on "hide upsupported modes"
