In recent years, anyone that has followed Joe Kane's discussions and purchased his DVE calibration discs have listened to his mantra about how the TV manufacturers could make their performance consistent from one to another but, realistically, they don't want to do it.

In the stores, when you have a bunch of monitors "side by each" transmitting the same picture at the same time, they will purposely do things internally(usually adjusting the color decoder) to make "theirs" look different from their competitors.

It has been going on for years with no change in sight.
