Video Acceleration with Powerpoint

I am trying to turn down the Video Acceleration settings in Windows Vista.

When you present video in Powerpoint it will only display video on the
primary screen. not the Secondary screen. Under Windows XP, you simply could
go to the Advanced section of the Display Properties then Troubleshoot where
you could turn the Video Acceletration down half way and the problem would be
solved. Under Vista that same option is greyed out.

We have a number of laptops and it seems to be a random thing with drivers.
ATI cards work no problem. NVIDIA depends on the model. A Gefore Go 7300
Laptop card, no problem. Same Driver set on GeForce 9500 GS Laptop card and
it doesn't work. All setup with the default settings.

Is there anyway to by-pass that greyed out option? Its greyed out even
before the graphics drivers are installed.

Thank You

It is a Vista Driver etc etc. Is the default driver from the Laptop
Manufacturer.

Is there any sort of reg tweak or something where I could force this feature
on. We do a lot of work for major conference centres in melbourne, Australia
and with out this feature of dual video they wont convert accross to Vista
