Pioneer Elite TVs allow for each input to have individual calibration settings. How is this done? I've gone through the owners manual and can't find anything on this topic. Kent
What is stored are the service and user settings, a calibration simply adjusts those settings for optimum performance. When the set is turned off or you change to another input the current settings are saved to non-volatile memory, then re-loaded when you turn the display back. There is a memory location for each different input.
If you change the calibrated settings you will lose your calibration. That's why you should always write down the settings before making any adjustments. FWIW, most displays have this, not just Pioneer Elites.
