Psst, buddy. Wanna buy a cheap plasma?”

You don’t often hear this from your friendly neighborhood white-van salesmen; they’re more into selling cardboard speakers. $1,200 HDTVs, no matter how good, just aren’t their thing.

They aren’t always ours, either, but when Samsung offered us the chance to have a look at its $1,200, 51-inch (diagonal) PN51E550D1F plasma, we couldn’t resist. That may be a lot of green for a public that once considered $300 a fair price for a new television, but today it falls solidly in the lowmid price range for a namebrand flat-screen HDTV in this size category.

All LCD HDTVs require some form of backlighting. The LCD panel’s pixels modulate the light and provide filtered color, but without backlighting to shine through the panel, you’d have no picture. Recently, LEDs (light-emitting diodes) have replaced the fluorescent backlights used in older flat-screen LCD sets. LCDs aren’t perfect in blocking light (which is why so many early models had poor black levels), but if you can shut off or dim the LEDs on demand, the LCDs’ light-blocking chores become far more efficient. And LEDs can do this; they can be shut off and turned back on almost instantaneously in reaction to the signal coming in.

There are those for whom a plasma TV won’t do. Maybe they’ve only seen plasma TVs in the store and think that LCDs look better. Maybe they have ?a really bright room. Sales numbers show that the majority of consumers choose LCDs.

Instead of starting this review by listing the features that Samsung put into its UN55EH6000 LCD TV, I’m going to start with what it doesn’t have. There’s no 3D. There are no Smart TV features. It’s not wafer-thin. It doesn’t even have an edge-lit LED back- light (though its “direct-lit” backlight does use LEDs). In other words, it lacks all the latest features found in most modern LCDs.

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.

Every year Panasonic’s flagship plasmas up the performance bar another (albeit small) notch, and the bar is now set very high. Plus, the TCP55VT50 has all the bells and beeps you’d expect from a top-of-the-line HDTV in 2012, including 3D (in active guise), smart TV streaming, a Web browser, optional 96-Hz refresh, and even a fancy touchpad remote.

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.
