I see generic PnP monitor. Which prevents world of warcraft from using
anything higher than 85hz.

The cm823f.inf file which is the driver for this monitor will not install.

When I try to install the device I get "The INF file you selected does
not support this method of installation"

If there is no working hitachi 823F drivers, then I need to know how I
can hack the registery to make 100hz work instead of just 85hz.

Thing is on the desktop I can set 100hz no problem. But I guess directX
cant see anything greater than 85hz cause its not using a driver for the
monitor.

The INF file is just a text file, is there something I can edit to make
it work with vista?

I finally fixed it. Seems there is a small difference in a 64bit inf
file and a 32bit. So in the cm823f.inf there was two lines I had to
change. And presto the driver installed. Rebooted and now I have access
to all the display modes in world of warcraft. Only took 6 hours to
find out how to do this.
