display setting on beamer change unmotivated after 10min...

Hi, I have a IBM T60p and recently installed VISTA enterprise.
When I connect the laptop to an external beamer, it all works fine and
properly detects the device and adjusts the resolution but after around 10min
of operation (using powerpoint) it just changed the resolution to something
else (lowers the resolution, so that only around 70% of the slide was
visible) without me having done something.
As this obvioulsy is a horror scenario during a presentation in front of
100people that I'll have in a few days, ....what can I do to make sure
something like this does not happen again?

I would be very gratefull to any help!

Hi,

Just a thought, but as it's a laptop is that the amount of time that the
system is set for going to sleep mode after a period of inactivity?
