You didn't say that.  Are you sure the '%i' option works right?

http://www.tightvnc.com/vncserver.1.php says vncserver runs Xvnc, and
the manpage of Xvnc says that the geometry option specifies the size of
the virtual display to be created by Xvnc, with 1024x768 being the
default size. So that should just work.

It leaves the question of how to connect to an already running "real"
X-session with a vnc client, though, which might be what are trying to
do.  In that case, you already have a given screen size which you cannot
simply shrink to a smaller size, and it might work if you start the
X-session on the sever with the desired resolution instead of the native
resolution of its display device.

Perhaps you need options in xorg.conf, as the manpage of Xvnc says:


,----
|        VNC parameters can be set both via the  command-line  and  through
|        the  vncconfig(1)  program, and with a VNC-enabled Xorg server via
|        Options entries in the xorg.conf file.
