For Shoppers, a TV Guide By ROY FURCHGOTT
WHEN most people buy a television, they measure the wall where they want to put it and then pick the largest screen that will fit. That is exactly the right way to buy a big TV, but it misses the point if you want the right TV.
The good news is that picture quality has improved radically in the last five years, even as prices have plummeted. The bad news: there are a bewildering number of specifications and features to consider. Many of them will matter only to hard-core videophiles, but some are critical to everyone.
One of the basic features is the type of set. Although projection and tube televisions are still available, most people choose either a plasma set or one of the two types of LCD televisions.
Most of the professional installers I consulted prefer plasma televisions. And if you want a flat-screen model that is wider than 50 inches, there are few other choices.
The installers say that plasma sets have the smoothest motion, the truest blacks — more on that later — and are more easily watched from side angles than the LCD variety. Moreover, “plasma is generally cheaper,” said Shawn G. DuBravac, the director of research for the Consumer Electronics Association.
But plasmas also use more energy than LCD sets — making them more expensive to run — and LCD sets can work better in bright rooms because they have higher bright settings than plasmas. “The electricity cost of powering the TV, even for the largest models, amounts to less than $2 a week,” Mr. DuBravac said. “That’s if you watch TV five hours a day, seven days a week.” The cost may not bother every customer.
There are also big differences among LCD sets. One technical distinction is that older LCD sets are backlighted by a fluorescent lamp, while the newer ones, called “LED LCDs,” are lighted by hundreds of LEDs. These models can be brighter and have a higher contrast than their older cousins, and they are thinner, too — less than an inch compared with three or so inches.
LED screens tend to have better black levels than the older LCDs. The reason: Regular LCD sets create black by closing off a crystal, but light can still leak through — think of a cloth draped over a lamp. The LED variety, with its hundreds of individual lamps, can effectively turn off the light source — that is, click off the light rather than drape a cloth over it. But even that is not perfect. Although there are hundreds of lamps, there are millions of the pixels that make up the set’s picture, so a “black” area will still have a few lighted pixels. In plasma sets, however, the cells that make up the picture are lighted individually, making its blacks better still.
Resolution — the sharpness of the picture — is a second major factor for buyers. A few years ago, there was a complex variety of choices, but there are now just two — 720p or 1080p. (These terms refer to the number of lines on the screen, with anything higher than 720 considered high definition.)
Generally, 1080 offers finer resolution at a higher price, but that is not the end of the story because television broadcasts, DVDs and Blu-ray all enter the set at different resolutions. To make the number of lines from the source match the number of lines on the set, the television must use its computing power to scale the picture, and its ultimate quality will depend on how well the set’s computer and software do their jobs.
There is no measurement for computing power. You have to rely on your eyes at the store, and maybe on experts’ and owners’ reviews. In one case, though, the 1080 is inarguably better, and that is for Blu-ray discs. They have 1,080 lines of resolution, so they can match any television bearing the same measure. To get the most from Blu-ray, however, dig deep into the owner’s manual to make sure the television set accepts a “24p” signal, (look under “allowable” or “supported” input signals). If not, even with the 1,080 match, the set will need to do more processing to convert the signal properly.
What about 3-D televisions? One downside is that the number of 3-D programs and films is sharply limited. A 3-D set is also nearly double the cost of a comparable 2-D set, and that does not include the cost of 3-D glasses, which are weightier than the old cardboard versions and cost $100 to $300.
As with many television tech issues, there is yet another twist: because 3-D requires so much processing power, the sets tend to have excellent computer processing. That capability means better pictures — even for people who use the sets only for 2-D viewing.
Unfortunately, the televisions’ computers are complex, and appraising them is not easy. Be sure to pay attention to the refresh rate. That is the speed at which the set can put up new pictures, and it affects how fluidly images move on the screen.
Video purists prefer a refresh rate of 60 hertz because it is “true” — the same rate as that of broadcast television. But on either kind of LCD set, that slow a rate can blur the motion in sports broadcasts and action movies. (“Motion blurring is not an issue” on plasma TVs, said Bill Schindler, a television engineer and researcher.)
To minimize blurring on LCD sets, many people prefer a 120-hertz refresh rate. When broadcast television sends out its 60 pictures a second, a 120-hertz set must fill in twice as many frames, guessing what a picture between the two broadcast images would look like, and then creating it. Most sets can handle a 120 rate effectively — but a 240-hertz rate can mean problems.
“There is an awful lot of interpolation going on at these higher frame rates,” Mr. Schindler said. “In the case of 240 you have to make up three pictures” for every real one received.
Moreover, the more processing required, the greater the likelihood of “artifacts” — processing mistakes that show up on the screen. A classic artifact: spokes that “appear to be going backward” on a stagecoach in a Western, said Joe Kane, a video display consultant. “If the processing isn’t very good, they appear to be going backward even worse.”
More and more televisions can be linked to the Internet, but if you plan to buy one, keep two things in mind. First, apart from the set itself, the quality of what you get will depend on your Internet speed. That may mean one more thing to upgrade. Second, as you browse, realize that the sites and services available on a Web-enabled television may change after your purchase. If a film service — Hulu or Vudu, for example — becomes more widely used, a TV maker may add it to the menu of links available. The shifting array of features makes comparison shopping difficult.
“If something is popular,” said Mr. DuBravac of the Consumer Electronics Association, “it’s going to be developed for multiple devices.”
Finally, what about the size of the set — the feature that many people deem all-important? Buyers may think they know the proper size, said Sy Paulson, a manager at the Best Buy store at Union Square in Manhattan, but their calculations are frequently “hit or miss.”
The critical factor is the distance between the viewer and the set. The rule of thumb is to take that distance — say, 60 inches — and divide by three, and the result — 20 inches — is the ideal height of the screen. (Screen height is usually about half the screen’s diagonal measure.)
With high definition, the picture will look good even close up. But if you get too close, you risk whiplash just trying to follow the action.

$73 an Hour: Adding It Up By DAVID LEONHARDT

Economic Scene
$73 an Hour: Adding It Up By DAVID LEONHARDT
Seventy-three dollars an hour.
That figure — repeated on television and in newspapers as the average pay of a Big Three autoworker — has become a big symbol in the fight over what should happen to Detroit. To critics, it is a neat encapsulation of everything that's wrong with bloated car companies and their entitled workers.
To the Big Three's defenders, meanwhile, the number has become proof positive that autoworkers are being unfairly blamed for Detroit's decline. "We've heard this garbage about 73 bucks an hour," Senator Bob Casey, a Pennsylvania Democrat, said last week. "It's a total lie. I think some people have perpetrated that deliberately, in a calculated way, to mislead the American people about what we're doing here."
So what is the reality behind the number? Detroit's defenders are right that the number is basically wrong. Big Three workers aren't making anything close to $73 an hour (which would translate to about $150,000 a year).
But the defenders are not right to suggest, as many have, that Detroit has solved its wage problem. General Motors, Ford and Chrysler workers make significantly more than their counterparts at Toyota, Honda and Nissan plants in this country. Last year's concessions by the United Automobile Workers, which mostly apply to new workers, will not change that anytime soon.
And yet the main problem facing Detroit, overwhelmingly, is not the pay gap. That's unfortunate because fixing the pay gap would be fairly straightforward.
The real problem is that many people don't want to buy the cars that Detroit makes. Fixing this problem won't be nearly so easy.
The success of any bailout is probably going to come down to Washington's willingness to acknowledge as much.
Let's start with the numbers. The $73-an-hour figure comes from the car companies themselves. As part of their public relations strategy during labor negotiations, the companies put out various charts and reports explaining what they paid their workers. Wall Street analysts have done similar calculations.
The calculations show, accurately enough, that for every hour a unionized worker puts in, one of the Big Three really does spend about $73 on compensation. So the number isn't made up. But it is the combination of three very different categories.
The first category is simply cash payments, which is what many people imagine when they hear the word "compensation." It includes wages, overtime and vacation pay, and comes to about $40 an hour. (The numbers vary a bit by company and year. That's why $73 is sometimes $70 or $77.)
The second category is fringe benefits, like health insurance and pensions. These benefits have real value, even if they don't show up on a weekly paycheck. At the Big Three, the benefits amount to $15 an hour or so.
Add the two together, and you get the true hourly compensation of Detroit's unionized work force: roughly $55 an hour. It's a little more than twice as much as the typical American worker makes, benefits included. The more relevant comparison, though, is probably to Honda's or Toyota's (nonunionized) workers. They make in the neighborhood of $45 an hour, and most of the gap stems from their less generous benefits.
The third category is the cost of benefits for retirees. These are essentially fixed costs that have no relation to how many vehicles the companies make. But they are a real cost, so the companies add them into the mix — dividing those costs by the total hours of the current work force, to get a figure of $15 or so — and end up at roughly $70 an hour.
The crucial point, though, is this $15 isn't mainly a reflection of how generous the retiree benefits are. It's a reflection of how many retirees there are. The Big Three built up a huge pool of retirees long before Honda and Toyota opened plants in this country. You'd never know this by looking at the graphic behind Wolf Blitzer on CNN last week, contrasting the "$73/hour" pay of Detroit's workers with the "up to $48/hour" pay of workers at the Japanese companies.
These retirees make up arguably Detroit's best case for a bailout. The Big Three and the U.A.W. had the bad luck of helping to create the middle class in a country where individual companies — as opposed to all of society — must shoulder much of the burden of paying for retirement.
So here's a little experiment. Imagine that a Congressional bailout effectively pays for $10 an hour of the retiree benefits. That's roughly the gap between the Big Three's retiree costs and those of the Japanese-owned plants in this country. Imagine, also, that the U.A.W. agrees to reduce pay and benefits for current workers to $45 an hour — the same as at Honda and Toyota.
Do you know how much that would reduce the cost of producing a Big Three vehicle? Only about $800.
That's because labor costs, for all the attention they have been receiving, make up only about 10 percent of the cost of making a vehicle. An extra $800 per vehicle would certainly help Detroit, but the Big Three already often sell their cars for about $2,500 less than equivalent cars from Japanese companies, analysts at the International Motor Vehicle Program say. Even so, many Americans no longer want to own the cars being made by General Motors, Ford and Chrysler.
My own family's story isn't especially unusual. For decades, my grandparents bought American and only American. In their apartment, they still have a framed photo of the 1933 Oldsmobile that my grandfather's family drove when he was a teenager. In the photo, his father stands proudly on the car's running board.
By the 1970s, though, my grandfather became so sick of the problems with his American cars that he vowed never to buy another one. He hasn't.
Detroit's defenders, from top executives on down, insist that they have finally learned their lesson. They say a comeback is just around the corner. But they said the same thing at the start of this decade — and the start of the last one and the one before that. All the while, their market share has kept on falling.
There is good reason to keep G.M. and Chrysler from collapsing in 2009. (Ford is in slightly better shape.) The economy is in the worst recession in a generation. You can think of the Detroit bailout as a relatively cost-effective form of stimulus. It's often cheaper to keep workers in their jobs than to create new jobs.
But Congress and the Obama administration shouldn't fool themselves into thinking that they can preserve the Big Three in anything like their current form. Very soon, they need to shrink to a size that reflects the American public's collective judgment about the quality of their products.
It's a sad story, in many ways. But it can't really be undone at this point. If we had wanted to preserve the Big Three, we would have bought more of their cars.
