What calibrations can be done to a Sammy DLP? I can't do it myself and really don't want to. How sensitive will these calibrations be to me moving the monitor around for cable connecting etc? If there are calibrations, I assume it is not cheap, are the differences worth it / noticeable? I obviously have a warranty, any chance I can get it covered through that? The local dealer will send out a service tech for any reason to check, the extended warranty even includes annual cleaning.
