Well, I had my Panasonic PT47X54 calibrated by Gregg Loewen. He mentioned how the tv was well built. He is truly a nice guy. He took about 4 hours to calibrate the set. The end result is, I am no longer using my big screen as a lamp. The picture looks more natural now. It takes time of getting use to because all of the default settings was set so high. My greyscale was nowhere close to calibration standard. The blacks looks black now, instead of being off color. Removal of the anti glare screen took about an hour with my set. We were very pleased with the end result. I would write a lot more, but I really want to watch Star Wars. Gregg is an excellent guy. He is very easy to talk to and tells you the process of calibration. Its worth the milk money . Thanks Gregg!!!
