hmm I think that would depend on Xorg setup. When run
the installer it gives you the selections to pick from
and then runs the highest (usuually) possible
reolstion unless you've doctored the config file
(haven't done that myself sinecd Xfree86 3.3.6)

I haven't used the live CD much myself, I'm thinking
itis going to default to highest resolution possible.

Once installed I think the easiest way to change this
(easiest meaning through a GUI tool, not direct file
editing) would be to install configure-debian and
change the Xorg configuration via that tool.

FWIW I've done this many times, when a HD is moved to
a new computer, new graphics card etc.

configure-debian doesn't need X to run.
