I only have one problem with this plasma TV, and I hope there is a setting which can resolve it. The only source from which I have noticed the problem is Netflix streaming using the Viera apps. U-Verse, Blu-Ray, Xbox, and Wii do not have this display problem: if there is a bright red object on the screen, the red colors will 'shake'. So if someone is wearing a red shirt on say, Buffy the Vampire Slayer - that entire shirt will noticeably vibrate on the screen - the edges of it shaking up and down just slightly. It is very distracting.
Is there a setting that can help resolve this? NO other colors on the screen are having this problem on Netflix. Very strange.
