Calibration is properly setting the brightness/contrast (grayscale) and color balance (and other settings such as overscan) for each input to established standards: usually displays out of the box or in showrooms have their settings 'cranked' (referred to as torch mode) to make the PQ appear better, but many prefer a properly set up display : a plasma is a fixed pixel display so many calibration steps such as convergence are not required
Calibration can be done by an ISF professional, or you can try it yourself using calibration DVD's or other equipment; or you can do it 'by eye' using a test pattern many broadcasters transmit :
Calibrators prefer to make adjustments in a service menu, if available, which is a menu not available to most consumers, so if a user made adjustments to easily available menus, you can get back to the calibrated settings: an ISF calibrator will leave you with all the setting info per input in written form or on a disc
Before an ISF pro would come to your home, he would ask that you have at least 100 hours of run time on your new plasma: there is a specific break-in procedure descibed in the Plasma Forum Master Burn-in thread: basically you turn down brightness settings from 'torch mode' and run full screen video (no static images) without logos or toolbars for the first 100 hours or more: many will tell you phosphor wear is greatest and most uneven on a new plasma: hence the reason behind this procedure
You don't have to calibrate a plasma, you can adjust the settings to your taste if you are happy with the picture, but you can learn a lot by seeing how an ISF calibration is performed, and a properly adjusted plasma could last longer if you do the break-in and properly calibrate it
