Port Replicator Querie (Monitor adjustments)

Assume that Suse 7.3 is installed on a laptop with an XGA tft 14" screen. The owner of the laptop buys a port replicator which will let him use his larger (19") monitor at his office. How should the adjustment for the external monitor be handled? If a special adjustment needs to be made for use with the larger screen through a port replicator, could the adjustment be done with a script that may be selected by the user on start-up?
