Just got my 55" installed, I was going to do a breakin, but can't read 100 pages of the stickied thread to find the relevant data. I may as yet do dNices settings if I can figure out how to do them properly but I've already used my TV, so it may just be pointless. I'm somewhat regretting not going with the Samsung because there is so much more calibration you can do without going into the service menu on the Samsungs. However I otherwise like this TV and we don't really like the silver Bezel of the samsungs. I don't understand why wireless has wires on the panasonic, seems incredibly moronic, I had to laugh at that when I realized the dumbass way the wireless is handled. Also insane and horrible is the permanently attached power cable. I have to unmount shelving from the wall to get the power cable behind them because the gap isn't big enough for that big end of the power cord. But those are pretty minor grievances.
I first tried Ken's settings, then tried DaveO's (panel brightness to mid) settings, both had one enormous problem, every caucasian person looked like they had insane spray on tans. They looked more like Dr. Seuss characters than like people. However, both of the settings had nice pop, clarity and depth to them. The THX settings have nearly perfect fleshtones but loses a lot of the clarity, it is incredibly dull looking, the THX improves by increasing Contrast to 75 but it's still a little disappointing, almost like it has a matte finish, or a dull film over the TV. The cinema mode is even more egregious in this regard, out of the box.
Guess I'll have to bust out the calibration discs and dial in my own settings. Still, I'm wondering if the GT can get as good color as my 3 year old 32 inch Samsung LCD. I guess I'll give it a couple weeks and if I can't get the color right on this TV will go for the Sammy.
ahh! right when I hit post, I looked up at the TV and saw my first Fluctuating brightness. Holy **** that is distracting... just checked, a build date of July 2011. I wonder if Panasonic comes and replaces the boards if Amazon will still take the TV back...
