Face it folks - Samsung/Toshiba/LG/Panny/Visio - well, any manufacturer of these sets is not able, with the current state of the technology and manufacturing processes, to produce one that does not have some type of anomaly that's clearly visible:
2) Vertical or Horizontal Banding
3) DSE (dirty screen effect), noticeable as vertical noise on source that has any type of camera panning
Plus a casual read through these threads shows numerous folks on the 3rd and 4th panel, and some are even going to plasma, which has its own issues.
I'm on my 4th panel, a current LG 47" set, and it has noticeable flashlighting, banding and DSE. My 3 previous Samsung sets were far worse, if that's possible. I've decided to stick it out until OLED is available later this year.
What I don't understand are the reviewers/press that seem to gloss over these inherent problems. Yes, the ultra thin panels have excellent resolution, incredible dynamic range, spot-on color, and very good black levels. Plus, the format is sexy
For static source, the picture can be mesmerizing, but once the action starts, all hell breaks out.
In order to produce these sets free of picture anomalies would probably require a retooling of the manufacturing process to far higher tolerances, which would add significant cost.
Buyer beware. And good luck.
