Calibration is an important maintenance aspect of every television. No matter what type you buy, you should ensure it is calibrated properly for the best viewing picture you can get. LCDs in particular should be calibrated every three months. This can be done at home and is easy to do once you get the hang of it.
When you buy a LCD television at the store, it does not come out of the box with the same picture. Most stores enhance the picture using built-in calibration tools to make things look as best as they possibly can, sometimes this is the picture folks want at home and other times they want something a little more subtle. Calibrating your LCD will help you find the best picture quality for your set-up and television.
