Make sure the monitor selection is correct -- I've found that the monitor
driver has more to do with what refresh rates are available than anything
else. -Ron

All,

Just found the solution to the t42 vista refresh rate issue, where
refresh rate is stuck at 50Hz.

Use regedt32 to set the create the following key

HKLM/Software/Microsoft/DirectDraw
ForceRefreshRate DWORD 0x0000004b (75)

That's it!

Enjoy

Thanks. We'll file that away in case we get a T42 some day and have a
problem with the refresh rate.
