THE VERDICT
A good overall performer and a solid first 4K effort from LG.

It’s rabbit season at the Sound & Vision ranch. The bunnies are reproducing at a torrid rate, and you can barely take aim at one before another dozen pop up.

We’re not talking cottontails here, but rather HDTVs. Yes, it’s that time of year again, when the new sets arrive en masse in anticipation of the upcoming end-of-year holiday season. The hot tickets this year are 4K (more precisely, 3840 x 2160) or, as it has been dubbed by the industry, Ultra HD, and OLED. On the 4K front, two new LG sets, at 55 and 65 inches, recently hopped into view to fill out a 4K lineup that began with the big 84LM9600—the latter our subject here.

With the introduction of its new 2013 XBR sets, Sony has shown that it’s serious about bringing Ultra HD, popularly referred to as 4K, to consumers at prices that, while still high, are less seizure-inducing than the $25,000 sticker on its 84-inch XBR-84X900 (Home Theater, June 2013).

Technically, 4K is shorthand for a resolution of 4096 x 2160 pixels—the professional 4K format. Consumer 4K sets, on the other hand, have a resolution of 3840 x 2160, exactly four times the pixel count of full HD 1080p. Regardless of the industry’s plan to refer to such sets as Ultra HD, 4K has already crept into the lexicon as the popular term for 3840 x 2160 home video.

With 4K-resolution Ultra HD the latest and greatest star in the consumer electronics galaxy, we ink- and pixel-stained wretches of the press were all champing at the bit to lay hands on one. But at a massive 84 inches diagonal, 216 pounds with its floor stand, priced high enough to put you in a nice new car as long as your tastes aren’t too posh, and still limited in availability, Sony’s new 4K flagship made the company understandably reluctant to ship review samples to all the usual suspects.

Full LED backlighting with local dimming, when properly implemented, is the gold standard for achieving the best black levels in an LCD HDTV. But such a set also requires a lot of gold to acquire. LED edge-lit designs, needing fewer LEDs and less complex processing, cost less. While LG makes fully LEDbacklit local-dimming sets (its LM9600 Nano designs), the company’s premier, edge-lit LM8600 offerings also include local dimming. Local dimming, even in an edge-lit set, is usually better than none at all, but it’s less comprehensive and in theory less effective than the fully backlit variety. We reviewed the 55LM9600 Nano back in our September 2012 issue. But the 55LM8600 now lays down a strong challenge to its pricier sibling.

It’s long been true that if you wait long enough, the price of technology will drop down to meet your budget. Flat-screen HDTVs are prime examples. We’ve recently seen manufacturers respond to the current global financial malaise by squeezing their beans hard enough to produce decent sets for around $1,000. While it’s difficult to say if this trend is due to economic conditions or pressure from price-aggressive new manufacturers, Vizio has been in the vanguard of the young guns making life difficult for traditional HDTV companies. And the company’s not standing still. Exhibit A: Vizio’s new $1,000 E601i-A3. Like its big brother, the 70-inch, $2000 E701i-A3, it’s a true budget buster, but for a change, the budget they’re busting isn’t yours.

The most popular, current approach to designing an LCD HDTV with LED lighting is to position the LEDs around the periphery of the screen and rely on diffusors to spread the light out uniformly. Sometimes (but not always) the brightness of the LEDs is also altered dynamically to help the LCD pixels create deep blacks, where needed.

Editor's Note: It's with great pleasure that Home Theater brings you this exclusive first review of Sharp's new ground-breaking LC-90LE745U HDTV. With this 90-inch set, the first at its size truly intended for mass production, Sharp begins the era of projection-size flat panels suitable for any light environment. While the $10,000 (street) ticket price still exceeds the cost of a high quality 2D/3D projector and screen, as a sign of what's to come, it is a significant introduction. And, as you'll read in Tom Norton's detailed review, not a bad TV. - Rob Sabin

Ninety inches diagonal is not all that big as projection screens go. But Sharp’s new LC-90LE745U, at that same 90 inches, is immense by flat panel standards. With more than twice the screen area of a 65inch set, it has little flat panel competition for its size, and none at all for its combination of size and cost. Panasonic has an 85inch plasma, for example, that will set you back nearly twice as much. LG showed a 4K 80-inch LCD set at last January’s CES, but exact pricing and availability is still undetermined. Mitsubishi offers a 92-inch rear-projection set at some remarkable street prices (around $3,000), but its massive 194 pounds and 25-inch depth (225 pounds and 32 inches in its shipping carton) might be just a little intimidating.
