Summary: I am very disappointed with the lights bleeding through in the corners of the screen on dark scenes and I am also disappointed with the graininess on dark hd broadcasts. Regular cable television has very poor picture quality. Bright broadcasts and sports are very good. I am no expert by any means but the overall picture quality of my old Sony wega LCD seemed to be better unfortunately it could not be wall mounted.
Summary: At first, viewing the Toshiba 46UX600 was a "wow" experience; the picture was as good, if not better, than than the 20-in flat-screen CRT Toshiba I had owned for years and years, and the $899 Costco price was about the best for an LED HDTV anywhere. But after a week or so, the minor disappointments started and just kept adding up. The first, of course, was the exclusion of Netflix in favor of the pay-per-view service Vudu.
Summary: I managed to get a killer deal on this TV and thought it would be a no-brainer upgrade from my brandless 32-inch 5 year old LCD. I was wrong. First, no Netflix in the widgets, only VUDU (which was expensive and not that great). I hooked my PC up for netflix access (which is a waste of the built in networking and wifi on this TV, but it's the only way to get netflix). The PC resolutions supported were terrible!
