I just picked up the 50U54 @ Costco & so far so good. Prior to purchase, I was on Sears somewhat darkened display floor & they had all the budget pdps, including the UT50 & the U50 looked just as good as it's 3d cousin. They had the LG, Samsung budget pdps too, but this U50 looked better than those also.
Colors & blacks look pretty darn good str8 out-of-the-box. Even the wife likes this panny, and she hasn't been a fan of them in the past.
Hoping more owners come here to share their impressions, issues & settings.
