Is it really important to have calibration on an LCD television?

Q.

A. Very, very few consumers need a professional display calibration. With few exceptions many of today�s displays are much improved over those of the past and have at least one display or picture mode that will provide acceptable grayscale performance straight out of the box. Consumers that purchase a good quality, well-designed display will rarely benefit from a professional calibration not to mention that such a service could potentially make your picture fidelity worse if you were unfortunate enough to hire a less than competent calibration service. Furthermore, there are many consumers that simply will not enjoy an accurate, optimized and/or �calibrated� video image while others cannot because their viewing environment is less than optimal (or in some cases because a consumer has color deficient vision.)

Like most consumers your best bet (assuming you own a reasonably well designed, well built LCD TV,) is to purchase or rent one or more of the popular display optimization (aka �calibration�) discs listed below in order to properly optimize your display�s settings. If after attempting to optimize your TV picture you�re still dissatisfied then you may want to contact one of the calibration services I�ve listed below. However, under no circumstance do I recommend that a consumer pay $250 to $400 for a professional display calibration on a television which has an MSRP of roughly less than five times the cost of the calibration.
