Panasonic 3DTV is far better than Samsung in many aspects, according to preliminary tests by Consumer Reports.
For example, not only are black levels far superior on the Panasonic sets, but if you leave your 3D glasses on while lying on a couch to watch the TV, the glasses get darker and darker the more you recline until they go completely black. The Panasonic glasses deliver the same clarity regardless of the angle of your eyes or head.
