Brightest Flashlight LED review

Samsung prices 2014 TVs at the high end, adds curved offerings

Today Samsung announced official pricing on its vast array of new 2014 TVs, including numerous curved and 4K/UHD sets first introduced at CES 2014 last January.

They ain't cheap.

Samsung's 4K models start at $2,499 for a 50-inch size. Compare that to Vizio, for example, which is charging $999 for its cheapest 4K 50-incher. On paper, the Vizio even has a picture quality advantage over the Samsung, offering full-array local dimming compared to Samsung's edge-lit variety.

Then there's the company's newfangled curved TVs. The entry price there is $1,999 for a 48-inch … Read more

Vizio's cheap E-Series TVs are brimming with local dimming

In the wake, in more than one sense of the word, of Panasonic's decision to stop making plasma TVs, there's now a hole in the TV market. It's right at the intersection of picture quality and value, a massive axle-rending divot left by the uncaring snowplow of market forces.

Absent as-yet-unannounced new plasmas from Samsung, this year it's up to LED LCD to pave the pothole. I'm pessimistic that any can reach the levels of bang/buck that the Panasonic S60 and ST60 achieved, but products like the Vizio E-Series -- with its affordable, effective … Read more

3D may be all but dead, at least on TV, but plenty of 3D films are still coming out in theaters and on Blu-ray. "The Hobbit." "Pacific Rim." "Man of Steel." "Thor: The Dark World." "The Wolverine." "Cars." "Cloudy with a Chance of Meatballs 2." "Gravity."

And numerous TVs are available with 3D capability -- and include the requisite glasses -- to handle playing those movies in the home. Until now, however, they all demanded severe picture quality sacrifices when you donned the glasses.… Read more
