changing the resolution of the screen

1
Hi
I display stimuli on the second screen of a system and I want to
change the resolution of this screen from matlab/psychtoolbox.

I know this can be done via the operating system controls, but that's
not what I want.
basically I am looking for something like

[winPtr rect]= Screen(2, 'OpenWindow');


Screen(winPtr,'ChangeResolution',[1024 768]);

or maybe Screen (winPtr, 'Preference','Resolution',[1024 768])

or a parameter added to the 'OpenWindow' command, or something one has
to call before the 'OpenWindow' command.
Is there a way to do that?
Cheers
M.
