Why don TV manufacturers calibrate their sets before they leave the factory?
Actually, they do! In so much that a 30 second automated 50IRE grayscale calibration is all that they do. On the production line, most manufacturers will make sure that a set will adjust in the middle of the grayscale. It is more of verification than a calibration. And of course, whatever the marketing department thinks the color temperature should be (to help sell the sets) is the “standard” that was used to calibrate your set.
