Calibration has long been a known method of improving the image quality a display produces. There are basically two ways that a television or projector can be calibrated.

The first is to adjust the set’s basic controls. These are the contract, picture, sharpness, etc controls that are easily accessible from the user menu. There are several DVD’s available to help in this process, including Video Essentials and Avia Guide to Home Theater. Using this method, a dramatic improvement in picture quality can be achieved.

The other way is to get a set professionally calibrated, often by an ISF technician. This involves getting the grey scale adjusted, setting overscan, focusing the lenses, cleaning, and more. This usually gives another large improvement in picture quality.

Doing these professional calibrations has become a small industry, and the AVSForum delves into it a little deeper.
