Size up your screen

After you have your budget squared away, you need to decide how large of a screen you want. Usually, the largest screens cost the most, but regardless, the TV should deliver the right-size picture for where you'll sit relative to the screen. Sitting closer to a smaller TV means you won't have to spend as much on a big screen. But if you sit too close, the picture will look poor. See the charts below for recommended seating distances per screen size for both 4:3 and wide-screen TVs, then consult our handy tool to find TVs in our database by diagonal screen size.

Regular TV-viewing distances
Most viewers feel comfortable sitting away from the set at a distance that's between three and six times the width of the screen. The following chart can give you a rough estimate of the minimum and maximum viewing distances for regular 4:3 televisions.

4:3 TV diagonal screen size	Min. viewing distance (in feet)	Max. viewing distance (in feet)
13	2.6	5.2

19	3.8	7.6

20	4	8

24	4.8	9.6

27	5.4	10.8

32	6.4	12.8

36	7.2	14.8

40	8	16

Wide-screen TV-viewing distances
You'll notice that we said regular televisions. Wide-screen televisions showing high-resolution DVD and HDTV look better than regular sets, allowing you to sit closer and experience a more immersive, theaterlike picture.

With wide-screen sets showing DVD or HDTV, you can sit as close as 1.5 times the screen's diagonal measurement and still not notice much of a loss in quality, while sitting farther away than three times the screen size means you're likely to miss out on the immersive feel. Here's a rundown of minimum and maximum recommended viewing distances for wide-screen sets.

16:9 TV diagonal screen size	Min. viewing distance (in feet)	Max. viewing distance (in feet)
26	3.3	6.5

30	3.8	7.6

34	4.3	8.5

42	5.3	10.5

47	5.9	11.8

50	6.3	12.5

55	6.9	12.8

60	7.5	15

65	8.1	16.2

Size and your room
Generally, 30-inch and smaller sets are great for bedrooms or guest rooms but too small for the main living room. Sets with bigger screens are large enough for the whole family to enjoy and will probably be too much for most small bedrooms. Remember that tube TVs are also fairly deep and get bulkier as the screen size increases. You'll want to pick out a deep-enough spot for the TV so that it doesn't protrude awkwardly into the room.

If you're mounting the set inside an entertainment center, be sure it fits in every dimension; also, leave an inch or two on all sides so that the TV has enough ventilation. If you're getting a bigger set, you may want to consider a dedicated stand; many TV makers sell matching stands that increase the aesthetic appeal of their hefty boxes.

Screen sizes and display types
Tube televisions have screens that measure between 5 and 36 inches diagonally. Above that, TVs switch from standard tubes to rear-projection or flat-panel models. Flat-panel LCDs can range anywhere from 5 inches to more than 70 inches diagonal, plasmas are between 37 and 103 inches, and rear-projection sets start at 37 inches and go to as large as 73 inches. These different TV types have their own strengths and drawbacks, which we detail in "Four styles of HDTV."

HDTV boot camp

Since the first HDTVs appeared in 1998, high-definition television has been on the mind of every TV buyer. The big question is whether now is the time to pay a few hundred to a few thousand dollars more and take the plunge on an HDTV set. We can't answer that question for you, but we can provide some basic information that may help you decide. But first, if you're completely new to HDTV, you may want to check out HDTV 101: A beginner's guide.

Analog, digital, and HDTV

Analog: An analog TV cannot display HDTV programming. It can show only standard-definition programs such as those found on regular TV, cable, or satellite channels--including digital cable and DirecTV or Dish Network.

Digital: The words "digital television" are used as a generic term for SDTV, EDTV, or HDTV.

SDTV: A standard-definition television is an analog television equipped with a built-in ATSC tuner (see below), which allows it to receive digital TV broadcasts. It will display a picture from these broadcasts, but HDTV shows won't look nearly as detailed as they would on a true HDTV.

EDTV: This stands for Enhanced-Definition TV, and usually it describes a television that can display HDTV signals but doesn't have enough resolution to really do them justice. Most often it applies to plasma TVs and denotes 852x480 pixels (more info).

HDTV: High-definition televisions, or HDTVs, can display standard TV, progressive-scan DVD, and HDTV signals. They're by far the most common type of digital television. Nearly every plasma, LCD, and rear-projection TV is an HDTV.

EDTV monitor or HDTV monitor: Describes a television that lacks a built-in tuner of any kind. These sets still work perfectly well with external tuners, including HD-compatible satellite and cable boxes

HDTV tuners

Samsung's DTB-H260F external ATSC tuner

Over the air: By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. If your HDTV doesn't have such a tuner, you'll also need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.

FCC tuner mandate: You may have heard that all TVs will have to be HDTVs by a certain date. That's not technically correct. The FCC has mandated that as of March 1, 2007, all new TV and video products imported into the U.S. or shipped to retailers that include an analog (NTSC) tuner need to have a digital ATSC tuner as well. There's a loophole though: if the product contains no tuner whatsoever--for TVs, this means it's a "monitor"--then the mandate does not apply. As a result of the mandate, nearly all televisions sold after that date should be ready for the analog switch-off.

Analog TV broadcast switch-off: Congress has passed a bill that requires over-the-air television stations to switch completely over to digital broadcasting after February 17, 2009. After that date, TVs and other gear with NTSC tuners will be unable to receive over-the-air broadcasts. Anyone who watches TV via "rabbit ears" or a rooftop antenna (as opposed to cable or satellite), and whose TV does not have a built-in or separate digital tuner, will stop receiving programs on that TV. Because the switch-off of analog TV broadcasts would deprive many viewers of their only source of television, Congress also created a subsidy program. Run by the government's National Telecommunications and Information Administration (NTIA), the program will provide $40 coupons, limit of two per household, each of which can be used to pay for one digital converter box. The boxes, which are supposed to sell for $50 to $70 each and be available from electronics retailers, can receive digital broadcasts to provide standard-definition programming to an existing analog-tuner TV. These coupons (which cannot be combined or used for other products) should be available from early 2008 through March 31, 2009 but must be used within 90 days of their issuance and only on certain converter products. As 2008 approaches, you can find more information on this program at www.dtvtransition.org.

Cable and satellite: The FCC's plans for ATSC tuners have nothing to do with HDTV over cable and satellite. Subscribers to pay TV services can simply get a set-top box that tunes HDTV channels, plug it into their HDTV-ready sets, and watch HDTV.

Some new HDTVs are digital cable ready (DCR), meaning they can tune digital cable channels, including HDTV if the cable provider has HDTV channels, without needing an external cable box. To use a DCR television, you'll need to get a special access card from your cable provider, called a CableCard. Unlike actual digital cable boxes, current DCR TVs can't do video-on-demand at all, and you must pick up a phone if you want to order pay-per-view programs. Using the card with some sets also means you can't access the electronic program guide (EPG), although many new DCR HDTVs include a third-party EPG, such as the TV Guide system, as a substitute.

HDTV resolutions

Resolution, or picture detail, is the main reason why HDTV programs look so good. The standard-definition programming most of us watch today has at most 480 visible lines of detail, whereas HDTV has as many as 1,080. HDTV looks sharper and clearer than regular TV by a wide margin, especially on big-screen televisions. It actually comes in two different resolutions, called 1080i and 720p. One is not necessarily better than the other; 1080i has more lines and pixels, but 720p is a progressive-scan format that should deliver a smoother image that stays sharper during motion. Another format is also becoming better known: 1080p, which combines the superior resolution of 1080i with the progressive-scan smoothness of 720p. True 1080p content is scarce outside of Blu-ray, HD DVD and the latest video games, however, and none of the major networks has announced 1080p broadcasts. Check out our comparison chart to see how HDTV stacks up against standard TV and progressive-scan DVD, and go to HDTV resolution explained for more detail.

Name	Resolution	HDTV?	Wide-screen?	Progressive-scan?
1080p	1,920x1,080	Y	Y	Y

1080i	1,920x1,080	Y	Y	N

720p	1,280x720	Y	Y	Y

Wide-screen 480p (DVD, EDTV)	852x480	N	Y	Y

Regular TV	Up to 480 lines	N	N	N

Regular TV and DVD on an HDTV

Regular TV on an HDTV: Many people bringing home an HDTV for the first time are disappointed by the picture they see. That's usually because they're watching a regular, standard-definition channel instead of an HDTV channel. Regular TV on an HDTV can look pretty bad, especially in comparison to high-definition programming. HDTVs are bigger and sharper than older standard-definition TVs, so they show off more of the flaws and relative softness of SD channels and content. Some HDTVs can improve lower-quality sources a bit more than others can, but in general there isn't much any HDTV can do to make standard-def TV programming look better.

DVD on an HDTV: HDTVs can make DVD, a very high-quality source, look spectacular, and most people are quite satisfied by the look of DVD on their HDTVs. Many DVD players, and all Blu-ray and HD DVD players, also have built-in upconversion or upscaling processing, which is supposedly designed to convert DVDs to high-definition resolution. In most cases, however, the benefits of this conversion process, if any, will be subtle.

Your HDTV tomorrow

If you buy an HDTV today, you can be fairly certain it won't become obsolete anytime in the next few years. Yes, new technologies come out every year, but nothing on the scale of the shift from standard-def to high-def TV will occur again for a good, long time. Nearly every current HDTV is equipped with a future-ready HDMI input, which assures compliance with tougher copy-protection standards, and as long as your new HDTV has one, you should be good to go.

Next: See wide-screen vs. 4:3

Updated February 5, 2008

Whether you want a new bedroom set or a massive home-theater centerpiece, our CNET editors' guide gives you the full picture on shopping for a new TV.

Wide-screen vs. 4:3

Television screens today come in two rectangular shapes. The most familiar one is called 4:3, which represents four inches of width for every three inches of height. You can also buy wide-screen, or 16:9, televisions, which take the same shape as many movies.

By now, nearly every TV capable of displaying high-definition is a wide-screen model, and we strongly recommend going wide for any TV larger than about 26 inches or so. The reason is simple: wide is the preferred shape of HDTV, and HDTV is the future. With a wide-screen TV, you can watch movies, high-def sporting events and most prime-time dramas and sitcoms in the expansive format in which they were meant to be seen.

Black bars and unused screen
When a normal, 4:3 TV displays DVD or other wide-screen video, black bars, known as letterbox bars, typically appear above and below the wide-screen image. Conversely, regular programs shown on a wide-screen TV may have bar to either side of the picture. In both cases, some of the screen goes unused and the picture you're watching appears smaller.

Screen size calculator
To find out exactly how much picture you'll be missing with either kind of TV, check out our calculator below. Just enter the diagonal screen size and aspect ratio of the set you're considering, then hit Calculate.

STANDARD 4:3 TV

WIDE-SCREEN 16:9 TV

Wide-screen TVs and 4:3 programs
Don't want to waste space on black or gray bars? All wide-screen TVs have ways to stretch, crop, or zoom the regular 4:3 image so that it fills the wider screen. These methods distort the image somewhat, but many wide-screen TV owners prefer looking at slightly stretched people rather than black bars. Here's a quick rundown of a few of the different names for selectable aspect-ratio modes found on wide-screen sets. Note that these names always vary by manufacturer, so they may not match up with your HDTV exactly.

		Normal or 4:3: Places black or gray bars to either side of the 4:3 image.

		Zoom or Enlarge: Magnifies the entire image, eliminating the windowbox bars but cropping the top and bottom of the image. Often, more than one level of zoom is provided.

		Wide or Full: Used for native 16:9 content such as that found on DVDs. With 4:3 content, such as regular TV, it stretches the image horizontally, making people look shorter and fatter.

		Panorama, TheaterWide, or Natural: TV makers have many names for modes that compromise between stretching and zooming to fill the screen. Some stretch the sides of the image more than the middle, so people in the center of the screen look correct. Some crop a little so that they don't have to stretch as much.

Whether you want a new bedroom set or a massive home-theater centerpiece, our CNET editors' guide gives you the full picture on shopping for a new TV.

Key features and connectivity options

Convenience features, inputs, and even the sound system are all factors to consider in your next TV purchase. Many TV makers differentiate their baseline models from step-up versions by including all kinds of add-ons, so check our list to help determine whether that "loaded" set you're considering really has the features that matter.

Picture-in-picture (PIP)

What it is: PIP lets you watch a second program in a little window. More-elaborate versions can resize the window, move it around the screen, create still or multiple still images, or simply divide the screen into two same-size pictures, often called "picture-outside-picture" (POP).

What it isn't: PIP has a dirty little secret, though: If you use an external tuner such as a cable box or a satellite receiver, you can watch only one program at once. If some of your channels are unscrambled, you can watch those on the second window, and you can usually watch other sources such as VHS or DVD on it, as well. But even with two-tuner PIP, a single cable/satellite box will prevent you from watching two live scrambled channels simultaneously unless the box itself has two-tuner PIP.

Universal remote

What it is: Plenty of TVs now come with universal remotes that can control other A/V gear. Usually, they work with a cable or satellite box, and many can also command DVD players, VCRs, or even A/V receivers. If you like watching movies in the dark, you should look for a remote with backlit or glowing buttons.

What it isn't: Not every universal remote can control everything. Some, known as unibrand remotes, can control only the same brand of equipment as the TV itself. Most are preprogrammed with a set list of codes, and if the codes don't match your older or off-brand gear, you're out of luck. A few are learning models that can accept the IR codes from your other remotes and, thus, control any kind of gear.

TV sound
What it is: Almost every TV sold today has MTS stereo reception and stereo speakers, which provide much better sound than a single mono speaker. When TV makers list readings of 5 watts per channel or higher, it means the set has a respectable audio system for a TV. Some sets with simulated surround provide a semblance of the effect of rear speakers.

What it isn't: No TV can compete with a dedicated audio system, so even if your set has lots of watts and simulated surround sound, you should consider a home-theater audio system for maximum impact. If you have such a system, the TV's sound becomes a moot point.

Tuner extras
What it is: Channel-surfing modes, favorite-channel lists, and other features that rely on your TV's built-in tuner can make switching channels a lot more efficient--as long as you use that tuner.

What it isn't: The problem is, many people use external tuners such as a cable or satellite box to change channels. If you're one of those people, tuner extras are all but useless to you.

Inputs and outputs
Perhaps the single most confusing item on a TV spec sheet is the forest of inputs and outputs used to hook up the set to other equipment. The following trail of breadcrumbs, arranged in order of video quality, should help put you on the right connectivity path.

Jack	Cable	Name	Typical use	Level of video quality
		RF aka radio frequency; antenna; cable; screw type; F-pin	Antennae, VCRs, cable and satellite boxes	Lowest, Highest (digital) for HDTV tuners

		Composite video aka yellow video; video; A/V (when combined with audio jacks)	Cable and satellite boxes, VCRs, DVD players, game consoles	Low

		S-Video aka DIN 4	Cable and satellite boxes, S-VHS VCRs, DVD players, game consoles	Medium

		Component-video aka component; Y, Pb, Pr; Y, Cb, Cr; broadband component; 1080i; 720p; HDTV	HD cable and satellite boxes, DVD players, HDTV tuners, Blu-ray and HD DVD players, game consoles, other HD sources	High

		RGB Connections can also be made through RCA or BNC-type connectors, and adapters are available between all of them aka PC, computer, VGA; 15-pin D-sub; RGB-HV	Computers, video processors	High

		FireWire aka IEEE 1394; iLink	some HDTV tuners, D-VHS VCRs	Highest (digital)

		DVI-D with HDCP aka DVI-D; Digital Visual Interface; High-bandwidth Digital Content Protection	Computers; older HD cable and satellite boxes, HDTV tuners and DVD players	Highest (digital)

		HDMI FAQ aka High-Definition Multimedia Interface	HD cable and satellite boxes, DVD players, HDTV tuners, Blu-ray and HD DVD players, game consoles, computers, other HD sources	Highest (digital)

Updated February 5, 2008

Whether you want a new bedroom set or a massive home-theater centerpiece, our CNET editors' guide gives you the full picture on shopping for a new TV.

Judging picture quality

The most difficult thing to judge when shopping for a TV is how good the picture looks. Good is a subjective term, so relying on the judgment of reviewers (such as CNET) may not get you exactly what you want. Then again, many reviewers scoff at the kinds of pictures that impress TV shoppers in the store. In this section, we'll offer some tips on become a more discerning viewer and what separates good pictures from the rest.

The wall of tubes
Most electronics stores show their televisions on a big wall, fed by the same video signal split a hundred times. Although bright lights, suspect salespeople, and a lack of remote controls will probably make any picture-quality judgment difficult, here are a few things to look for on the wall.

Don't fall for brightness. Almost every television on the sales floor is set to the brightest picture settings, so try to get the salesperson to reduce the controls of the TVs you're comparing. You want the pictures--not necessarily the controls--to be roughly equal in brightness, contrast, and color.
Go out of the light. Few living rooms are as well lit as the sales floor, so see if the salesperson can reduce the amount of light shining on the picture. If nothing else, try to shade the screen if light is shining directly on it.
BYO DVD. If you have a DVD that you're familiar with, see if you can use it instead of the TV signal that's normally shown. Aside from HDTV, Blu-ray, and HD DVD, DVD provides the best picture a television can display, so it makes for a good reference from which to judge.
Try all the picture modes. Many sets come with numerous picture presets, such as Movie and Sports, that radically affect how the image appears. After you peruse the manually adjusted pictures, try the different presets and modes to see which ones look best.

Features that affect picture quality
Picture quality is the main characteristic used to sell TVs, but very few features actually affect picture quality in a helpful way. We'll run through a few here.

Picture settings: Proper adjustment of a TV can have a larger impact in picture quality than anything else, and for proper adjustment you'll need a good range of picture controls. Many controls are superfluous, but quite a few, including color -temperature presets, a full-range backlight control (LCD flat-panels only), and the ability to turn off harmful picture-affecting features can go a long way toward making your TV look its best. For more on setting up the picture, check out Picture perfect: HDTV tune-up tips.

TV technology type: The technology behind an HDTV is probably the second-biggest "feature" to impact picture quality. LCD, plasma, CRT, and rear-projection all have different, if sometimes subtle, differences, and it pays to get a handle on each before you buy. Further details can be found at Four styles of HDTV.

Resolution: In the realm of HDTV, resolution is the most often-cited spec. And while resolution is important, nearly all HDTVs have enough pixels to do high-def sources justice. In other words, you don't need 1080p to enjoy a great HDTV picture, and in fact, many times it's almost impossible to tell the difference between a 1080p TV and a lower-resolution model of the same size. For details, check out HDTV resolution explained.

Video processing: Many new HDTVs have video processing modes, such as 120Hz (Picture perfect: HDTV tune-up tips."

Video gaming and computer tips
DVDs aren't the only non-TV content that's likely to be shown on the tube. Here are a few other pointers on what to look for in a television that'll do multimedia duty.

Game consoles
The sweet graphics of the Xbox, the PlayStation, and the GameCube, not to mention the Xbox 360, the PlayStation 3, and the Wii, can take full advantage of high-end televisions, but even inexpensive sets do best with a few added features in the mix.
- Front-panel inputs. A set of A/V inputs on the front or side panel of a TV makes hooking up and disconnecting a game console--or a camcorder--much easier.
- Picture preset. Many TVs come with picture presets that affect the contrast, brightness, and other controls. Some presets crank those values sky-high to provide a more intense picture. If you like that bright image, check out sets with Game, Vivid, or Sports presets.
- S-Video inputs. Console graphics look best through better connections, so you should at least your hook up your game system via an S-Video connection instead of the standard composite-video cable that ships with the system.
- Component video inputs. For a big improvement in gaming video quality, step up to a TV with component video inputs. The downside is that you might have to buy a special adapter for your game console. Some of these adapters also include connections for digital sound, but you'll need a home-theater system or a surround-sound setup with an optical digital connection and support for Dolby Digital sound to take advantage of the superior sonics.
- HDMI inputs: All PlayStation 3s and newer Xbox 360s have HDMI outputs, providing the best-quality video connection to compatible HDTVs. In reality though, most people have a difficult time telling the difference between a picture delivered over component video and one that comes via HDMI.
- Burn-in. Some high-end TVs, namely plasmas, can become permanently scarred by very bright, stationary images that remain on the screen for a long time; think of a paused game or that constant score/life-bar/ammo-count graphic. However, we consider the danger of burn-in to be greatly exaggerated and plasmas can be fine candidates for all but the heaviest gaming situations.
Computers
Today's televisions have plenty of connections and capabilities, and plasma, LCD, and most rear-projection HDTVs usually make excellent big-screen computer monitors. If you want to use your TV as a monitor for games, Web surfing, and other tasks, here are a few tips:
- Don't bother with standard-def TVs. CRT-based direct-view and rear-projection televisions, as well as smaller 640x480 LCDs, don't make very good computer monitors. They display only low resolution, and often lack the proper inputs.
- VGA input = good for computers. If you're serious about using your set as a big monitor for standard software, look for a VGA-style RGB input, just like the kind your computer monitor uses (see Inputs and outputs for more).
- HDMI or DVI input = best for computers. The best types of inputs are digital, so if your TV has a spare HDMI or DVI input, you'll usually get the best performance by matching it to your PC's digital output. Often the PC has a DVI output and the TV has only HDMI, so you'll need an adapter cable to make the connection.
- Match the native resolution. As with LCD computer monitors, you'll usually get the best PC picture by matching the native resolution of the TV to the output resolution of your PC. Some HDTVs can't accept PC sources, especially via VGA, at their native resolutions however, which makes them less -than- ideal for use as monitors.

Accessories and warranties
With any large purchase, the urge to accessorize can be overwhelming. Here are a few add-ons to consider, as well as some words on warranty and shipping concerns.

Accessories
- Cable requirements. In the store, you'll probably hear a salesperson tell you to get extra cables. That's because overpriced cables are one of the few areas where electronics stores can turn a big profit. In reality, cable quality matters very little, especially with digital cables such as HDMI. Since many stores don't even carry lower-priced cable alternatives, we recommend shopping for cables online and buying based on price from a vendor with a good return policy. Our current favorite is monoprice.com.
- Surge protector. We definitely recommend shielding your TV investment with some sort of surge protector. Don't believe the hype that a better protector will somehow improve video quality, but do choose a model with coaxial inputs and outputs for your cable or antenna.
- Furniture. Many TV makers produce matching stands for their larger TVs. If you like their style, they usually make setting up the TV a lot simpler. That's because you won't have to worry about your stand being able to support the TV or being the right height for comfortable viewing from the couch.
- Other room treatments. Watching TV in broad daylight will result in a washed-out picture. We recommend that any viewing room be equipped with curtains or other window treatments that can block out some light during the day and that the TV screen face away from the window. Try to keep room lighting from reflecting onto the screen. A low-wattage light placed behind the TV in an otherwise dark room can make an ideal viewing environment.
Extended warranties
The final question you'll be asked when buying a TV is generally, "Would you like an extended warranty with that?" Although in this section we previously advocated a few aspects of extended warranties, mainly because of the relatively untested nature of new HDTV technologies, we're changing our tune. Most buyers should skip the extended warranty. According to the March 2008 issue of Consumer Reports, the overwhelming majority HDTVs do not need repair during the warranty period. Rear-projection HDTVs do exhibit a higher rate of failure than flat-panels in general, but are still quite reliable and again not worth an extended warranty. CR goes on to mention that many credit cards and some retailers, such as Costco, will extend the manufacturers' warranty free of charge, which seems like a better deal to us than spending hundreds on an extended warranty.

Manufacturer warranties
The standard warranty covers parts for one year and labor for 90 days. Some manufacturer warranties have separate time frames for the picture element--such as the tube, which is often covered for two years--and the rest of the TV. High-end TVs, especially plasmas, often have a one-year labor warranty. Some manufacturers also offer in-home service on more expensive and larger models that are difficult to ship.

Buying online
You can often get a great deal if you buy your TV online, but you should be aware of some differences.

An increasing number of TV makers are cracking down on "unauthorized" retailers of their sets, especially online, and some will not honor warranties on products purchased from such dealers. See the Web site of your set's manufacturer before you purchase a TV online for its policy on unauthorized retailers. Not coincidentally, unauthorized merchants often have the best prices.

If you decide to buy your TV online, make sure you choose a vendor with a solid return policy. There are many cut-rate vendors out there that don't allow any returns on televisions--an exception to their standard return policies. Also, be prepared for a significant shipping fee. If there is a problem with the TV, many brick-and-mortar retailers will accept a return no questions asked, while online merchants often make you pay return shipping and/or a restocking fee, provided they accept returns on TVs at all.

Consider how to get it through the door and set it up in your room or on a stand; big TVs often require more than one strong person to lift them. Some online and many brick-and-mortar dealers will move the TV into your house and even set it up for you, but it usually costs extra.
