How big a screen size do you need? Plasma TVs come in fewer screen sizes than LCD sets. Although more screen sizes are available than before, the smallest current plasma TVs are 42 inches, while the biggest ones sold to consumers are 65 inches. LCD and LED TVs, on the other hand, can range from just a few inches to 90 inches in size. For home theaters, LCD TVs with screen sizes from 32 inches to 65 inches are most popular.
How big of a screen do you really want? Because plasma HDTVs have much higher resolution than conventional TVs, you can sit closer than you formerly could. That means you can get away with a bigger screen in a smaller room. Even so, a very big screen could look great in a showroom but overpower a living room or family room. A lot of websites offer advice on screen size. THX provides some suggestions, as does Audioholics.com.
What's the lighting like in your viewing room? While some plasma TVs do just fine in brighter areas, most do a better job in dimly lit rooms. They often excel at creating deep blacks and displaying details in shadowy areas of the picture, but most can look washed out in rooms that are brightly lit. Many plasma screens are also prone to glare because they're more likely to reflect any light sources. If you want a plasma TV for a room that's not perfectly light-controlled, only consider sets with higher brightness and special glare-fighting screens; appropriate sets are identified in our reviews. Otherwise, consider LED/LCD technology.
Are you concerned about energy efficiency? Plasma TVs are more energy-efficient than they used to be, but they still trail LCD TVs by a wide margin. Despite improvements in the latest generation of plasma sets, LCD televisions are typically far more efficient to operate. In most cases, only the smallest plasma TV screen sizes in a given series are Energy Star qualified.
Is streaming worth worrying about? Streaming offers additional entertainment options when your TV provider
disappoints. Netflix, Amazon Instant, Hulu Plus, Vudu, CinemaNow, Facebook,
YouTube, Flickr, Pandora and more are among the major streaming apps. There are
hundreds of others, but the lineup of streaming partners will differ by manufacturer.
Most sets with streaming do provide a varied roster of sources, although some
less expensive sets might have only a handful. Built-in Wi-Fi is a must unless
you have a hardwired network connection. If you opt for a more basic set
without streaming, you can add it via a Blu-ray player
or a set-top
Is 3D of interest? 3D is appearing in more and more midrange and even budget plasma TVs. Plasma sets do a good job with 3D for the most part, although some issues like ghosting do crop up from time to time. Keep in mind that current plasma sets exclusively use active-shutter technology, which uses relatively expensive glasses, and only Samsung includes any in the box.
Do you need a mount? If you plan to use the included table stand, you can skip right over this. However, if you want to hang your flat-panel plasma TV on a wall, you'll need a wall mount. Because plasma TVs are much heavier than LCD and LED sets, you'll also need a relatively sturdy choice. Our report on TV wall mounts covers some of the options.
Should you be worried about burn-in? Caused by damaged pixels that leave a permanent ghost of a static image on the screen, burn-in was a problem with early plasma models. However, new technology reduces this risk, and experts generally say burn-in is no longer a concern with most sets. LCD TVs have no burn-in risk, although temporary image retention is a similar but less severe problem. In this case, a static scene leaves behind an annoying ghost that takes several minutes or more to completely disappear. Most plasma TVs include anti-image-retention features to get rid of temporary image shadows more quickly. Reports say that temporary image retention seems to decrease as a plasma display ages.
What about the warranty? Check the manufacturer's policy before buying online; some have strict policies regarding authorized dealers. In those cases, if you buy your plasma TV from an unauthorized dealer, you'll probably violate the terms of the manufacturer warranty, although the retailer might offer a substitute. While there can be a substantial difference in price between authorized and unauthorized dealers, if you plan to buy from the latter, be sure to calculate your threshold for risk on such a large purchase and ask the dealer about warranty coverage.
Dollar for dollar, plasma TVs cost less than LED sets of equal screen size, picture quality and features. The trade-off is that plasma's unique characteristics require you to consider where you'll use the TV when determining if plasma is right for you. If you plan to watch your set in a room that's often well lit or that has inconveniently placed windows, an LED set might ultimately provide more satisfaction. Plasma also uses more energy than an LED TV, so the annual cost of ownership will be a little higher. Finally, some manufacturers -- notably Samsung -- have introduced unilateral pricing policies that limit the lowest price for which its sets can be sold by authorized dealers. As a result, the TV will cost the same whether you buy it online or from a brick-and-mortar retailer, even during major discounting events like Black Friday.
