Now more than ever, both bargain hunters and luxury seekers can find an HDTV to satisfy their high-def needs and their budgets. Whether you want an LCD, plasma, or DLP HDTV set, you can choose from a wide range of prices, and even the high-end models aren't as expensive as you might think. And you'll find more high-def content--from network and cable broadcasts to HD DVD movies--than ever before.

Deals abound in every size and technology category. "PC World" tested a total of 15 TVs across three popular technologies

(LCD, plasma, and DLP) and three popular screen sizes (37 inches, 42 inches, and 50 to 52 inches). For a little over $1000, you can buy an LCD or plasma TV with impressive picture quality. And today, thanks to DLP technology, a gigantic screen and even 1080p resolution may be within your reach.

To test each of the TVs, we played several high-definition clips, a couple of standard-definition clips, and scenes from two DVDs on each set. Our panel of judges scored each model based on its brightness, sharpness, and color clarity. Our verdict, after a thorough comparison of the sets: Lower-priced HDTVs frequently equal or better the performance of higher-priced sets. In addition to pinpointing which of the tested models are true screen stars, we have tips on how to shop for deals. Armed with this information, you'll be able to tell whether the next bargain that catches your eye is a great deal--or just a snare for the unwary.

Big: LCDs

In our tests many cheaper HDTVs, including bargain sets from little-known brands like Olevia and Vizio, more than held their own against higher-priced models from makers such as Samsung and Sharp. In the 37-inch LCD category--a size that we've never previously evaluated--the Best Buy award goes to Vizio's L37HDTV, which climbed to the top with particularly high scores for brightness, color, and DVD content. At a street price of just $1000, this set may be the one for shoppers on a limited budget. Not far behind, however, are the $1299 ViewSonic N3760w and the $2000 Sharp Aquos LC-37D90U, the latter model the only LCD we tested that supports a 1080p resolution. Westinghouse's $1299 LTV-37w2 and Olevia's $1499 537H claim the fourth and fifth positions, respectively. Though not as well equipped as other sets, they provide enough of the basic features; and more important, their TV images earned decent scores in our image-quality tests.

Many consumers are familiar with the workings of LCDs, in the form of LCD monitors. For LCD TVs, the technology is the same: A matrix of cells contains Liquid crystals that twist and untwist in response to the provided voltage, allowing light from the source to pass through and thereby creating color images.

A 37-inch LCD TV looks big in a small living room, and it's a good option if you want a wall-mountable model. If this is your ideal dimension for an HDTV, an LCD set is your only budget choice: Aside from Panasonic, no plasma TV manufacturer makes 37-inch models, and DLP televisions aren't made in this size at all.

HDTVs aren't just about pretty pictures. Here are other factors that influence how well an HDTV set works in a room--and how much getting a TV up and running costs.

The Eye of the Beholder

Each of the three HDTV technologies has advantages, so picking one is a matter of your viewing preferences. But keep in mind that many formerly common problems are passing into history.

LCDs may experience motion blur, due to limitations in pixel response times. This is hardly a problem with plasmas and DLPs, and it's less pronounced with today's LCDs than with past models, but generally a fast pixel-response time is desirable to minimize the effect in an LCD TV. All but one of the LCDs we tested for this review have a vendor-rated gray-to-gray response time of 8 milliseconds--speedy by industry standards. Sharp lists an even faster gray-to-gray response time of 6ms for its Aquos LC-37D90U.

A plasma TV's life span was a consumer concern during that technology's infancy. According to iSuppli's Patel, however, plasma tubes are now rated for an average life of 60,000 hours--so even if you watch 5 to 8 hours of TV a day, your plasma TV panel won't diminish to half its original brightness for 20 to 30 years. Burn-in on plasma TVs--wherein repeated, prolonged exposure to the same image causes the image to sear into the glass of the TV screen--has also become a rarity.

DLPs sometimes suffer from a "rainbow effect," in which some viewers see a rainbow trail when their eyes move from one part of the screen to another. Not everyone sees this, and Patel says that manufacturers have tried to reduce the "margin of error" by adopting technological innovations such as the six-color wheel, color wheels that spin at double speed, and a color processing technology called BrilliantColor from Texas Instruments (which invented DLP technology).

Color control is important to videophiles, and DLPs equipped with the six-color wheel are unrivaled in this area. The Mitsubishi DLP we tested, for example, offers controls for red, green, blue, yellow, cyan, and magenta. Controls for RGB appear in some LCDs, but normally are included only in higher-end sets. Oddly, of the LCDs we tested, the value-priced Olevia 537H alone has one of these powerful RGB controls. Meanwhile, all of the plasma screens we tested except the Vizio P42HDTV have RGB controls; and its omission is likely a matter of cost-cutting by Vizio to reach the set's $1400 price, rather than of technological limitations. (Other, more-expensive plasma sets provide RGB--or even six-color--controls.)

Patel of iSuppli states that if you "put an LCD, plasma, and DLP set side-by-side, the LCD looks the best." Nevertheless, she thinks that plasmas do well with movies, because "black levels are very nice and colors have a lot more warmth." In addition, she notes that DLPs have a significant advantage with BrilliantColor, which adds brightness and color vibrancy.

Young has a different take. He cites a test that DisplaySearch performed comparing the viewing angles of various LCD, plasma, and DLP sets. Although "LCD TV has improved," he notes, "[plasma] is still superior." Even better are DLPs, which, like other rear-projection TVs, "are much more consistent across the viewing cone" (referring to horizontal, vertical, and diagonal views), Young observes.

"PC World"'s test procedures entail direct comparisons of TVs that have screens of the same size. This approach prevents us from crowning any technology in this review as overall champion. Even among our panel of testers, and among experts like Patel and Young, personal preferences influence evaluations. HDTV screen quality is subjective and best appraised by the person who will view it regularly.

What Else to Look For

All of the units we tested have HDMI connections, which are necessary for an optimum HD picture. You also need to have an HDMI cable, which almost never comes with a set. Check to see whether your peripherals already have them, or whether you need to buy a separate one. On the set you're considering, also look for an ATSC tuner, which accepts a digital signal and thus is the only way to receive over-the-air HD broadcasts. All of the TVs on our charts have such a tuner (in addition to an analog NTSC tuner) and can be called HDTVs. Some other models, such as the unranked Maxent MX-42HPM20, are actually HD monitors, meaning that you'll need to obtain a separate tuner for them, which can add to the total cost; if you already have a cable box with a tuner, buying a monitor can save you hundreds of dollars.

A few of the HDTVs we reviewed, such as the budget RCA Scenium M50WH185 DLP and the ritzier LG 42PC1DA plasma, have CableCard slots--an appealing extra. Shaped approximately like a PC Card slot, the CableCard option promises to someday replace bulky cable boxes with a slim card that's hidden from view. For the present, however, cable providers do not widely support this feature.

Though none of the models' built-in speakers produced home-theater-quality audio, many of them performed adequately in our tests, and a few--notably the RCA DLP's speakers--rose above average. Some TV sets, like Samsung's HL-S5087W DLP, offer more-unusual connections, such as USB ports to which you can attach a digital camera for viewing photos directly on the TV.

HDTVs Need HD Content

Of course, what good is a high-definition TV without high-definition content? Already, iSuppli's Patel notes, the old deadline of January 2007 for moving TV content to an all-digital format "is long gone," replaced by a newer deadline of February 2009. Fortunately, several providers are now rolling out at least some popular programming in HD. Patel says that "the majority of sporting events are broadcast in HD."

The resolution of current HD programming varies by channel, but as of this writing most content is either 720p or 1080i. DisplaySearch's Young points out that most of the networks broadcasting in high definition do so at 1080i resolution; the exceptions--ABC, ESPN, and Fox--use a 720p high-def signal. For instance, ABC broadcasts its HD-enabled shows, such as "George Lopez" and "Grey's Anatomy", in 720p, while NBC offers programs like "Law & Order" and "Late Night with Conan O'Brien" in 1080i. True 1080p compatibility, incorporated into a few of the models we tested, ensures that you'll get the full experience when DVD movies and TV shows formatted at that resolution finally become widely available; very little 1080p content is currently on the market.

This holiday season, several Blu-ray players and a few HD DVD players will be on store shelves; but these devices and the compatible media they require are, as yet, hard to find. One popular game console, the Xbox 360, has many games available in 720p or 1080i, and the new PlayStation 3 likewise promises support for games and movies with 1080p resolution.

Low-priced HDTV sets keep getting more affordable, and our testing shows that some of them display good images. A few high-end features and adjustments are trickling down, too, so these days you can more easily obtain what you want without paying for irrelevant frills. If you are raring to see movies or the Super Bowl in high-def, check out these models--because "high-definition" no longer necessarily means "high-priced."

Shopping Advice: Buy Low, Receive High-Def in the Bargain--Online

For Web-savvy bargain hounds, the traditional brick-and-mortar experience is no substitute for deals a few mouse clicks away. Saving hundreds of dollars may be the biggest consideration for some HDTV hunters. Here's a guide to help you find hidden buys on the Web.

Deal forums:
FatWallet and DealCatcher, Web sites for deals in many categories, often post special prices for HDTVs from different retailers. In addition to noting manufacturer coupons and sales, the sites' forums also post clever price-matching strategies and coupon "stacking" techniques (ways to use several coupons for a bigger discount). Techbargains devotes an area specifically to TVs.

Online outlets: Going to an outlet mall used to mean driving a hundred miles for deals that turned out to be so-so. But online manufacturers' outlet stores don't require a car--and the deals they offer, if you don't mind refurbished sets, deserve a serious look. Philips's outlet site presents a nice selection from the company's LCD and plasma lines, and the occasional DLP bargain. Sony's outlet store also has refurbished or closeout TV sets now and then. Dell has a bigger inventory of LCDs and plasmas at its outlet and often sweetens the pot with special offers, such as free shipping.

Price-comparison sites: For ease of finding retailers that offer a specific model, few resources can match the efficiency of price-comparison Web sites. NexTag, Pricewatch, and PriceGrabber.com all qualify as reliable favorites. (Note: PriceGrabber.com is PCWorld.com's longtime pricing partner.)

Keep in mind that return policies vary greatly. Getting service for an online-purchased TV may turn out to be more difficult than getting it for a model you bought at a local electronics store. But if you think the potential service loss is a risk worth taking for the savings you'll reap, a cheap HDTV may be just a click away.

HDTVs aren't just about pretty pictures. Here are other factors that influence how well an HDTV set works in a room--and how much getting a TV up and running costs.
