Calibration — adjusting the brightness, color, tint and other parameters of your TV — can be as much an art as a science. Professional technicians use equipment to get it just right, but you can get close with some simple tools.

First stop by TweakTV.com and look through its database of settings often used by professionals for specific TV models. TweakTV's collection of settings isn't perfect — every TV varies a bit — nor does it include every model. But it will get you started on the right path.

You can also use a calibration Blu-ray disc that provides test patterns and instructions for adjustments, such as Disney's World of Wonder, a $27 tutorial designed for novices. (Some of these tools also help you adjust your audio.)

If you'd rather have a free, do-it-yourself option, you can burn a copy of the AVSHD 709 Calibration disc from a download on the site.

And if apps are more your style, you can calibrate your TV by downloading the $1.99 THX Tune-Up program from the Apple App Store. (You'll need Apple's AV cables or an Apple TV to send the calibration image from the app on your device to your TV screen.) 

Most televisions provide myriad adjustable settings, the most important of which are contrast and brightness. If the contrast is too high, the bright whites can lose all detail. If it's too low, you'll lose details in dark areas — for example, the finer folds in a character's black suit.

Color can be very tricky to nail down, even with the aforementioned calibration tools, because TVs typically have a color bias based on the manufacturer's preferences. This often explains why on some TVs, people may look a bit jaundiced, greens may be especially punchy or lips may be candy-colored red. Adjusting the color control will help, but doing that alone may not solve the problem completely. You may also need to adjust the tint control, for example, to make sure that people don't look greenish.
