Most modern TVs are accurate enough out of the box that they don't need calibration. Just follow our five simple tweaks to get the best picture settings for your TV and you should be good to go. Still, if you spent a lot on your new TV, you might want to get it calibrated to obtain the best picture possible. Professional calibrations can cost hundreds of dollars, but if you have a high-end home theater (the kind you hired someone to build for you), it can be a worthwhile added expense. You can also use the Apple TV's Color Balance feature, though it doesn't come close to a professional calibration and only affects the Apple TV device's (not the Apple TV app) output itself. And, of course, don't forget to turn off motion smoothing (the effect that makes everything look like a soap opera) unless you're watching sports.
