On request, he said,
Far are the days when you see how big a screen you wanted, saw a number of sad, and bought one of the best pictures that suits your budget. An explosion is an option to buy land te?kovan? with numbers, functions and terminology that even the experts sometimes have to keep (not me, though). We need to reduce the chaos to give you the information you need to be on speed. When you find your way into high-ret, A / V world, and not just go for numbers - indeed, some are important, but do not. Let us quickly through a few.
Important: Contrast
Contrast ratio refers to the darkest and brightest light values can be displayed simultaneously. All other things are equal, higher contrast ratio, more is better. Everything else is rarely the same, however.
Pumps up to a maximum light, for example, increasing contrast, but it will do nothing to help the poor black levels - which, in our opinion, is a much bigger problem. LCDs are especially hard to bear setm?. So take contrast, the assessment as a very broad to be supplemented by eyes-on prediction. LCD, the contrast ratio requirement at the beginning of 600:1, while those on the start of plasma from 1000:1. Although the vote of 10000:1 or more are common for both types of shows, they should approach these claims with a little healthy skepticism. Believe your own eyes. Keep in mind that if you have a showroom floor, you will be monitoring the HDTV is in connection with stamping on the light, not yours. You’re looking for the dark cave, or in a well-lit, open space? Maybe cleverest idea is to determine whether to return to the store policy before buying.
Important system
The ratio represents the ratio of width of the screen. Conventional sets have a ratio of 4:3, while the 16:9 widescreen models. Wide screens are the future. HDTV is a widescreen format, for one thing. Second, most of the DVD and look better in the wide-screen displays, because almost every film, which during the last 50 years was shot in the ratio of 1.85:1, or (very close to 16:9, which is 1.78:1) for 2, 35: 1 (even wider than 16:9).
Important video inputs
The number and nature of video inputs to determine what resources can be used for display.
Composite video: This type of entry is low quality, but in most widespread compatibility. Each device, video, composite video outputs are among them. Connect a 75-ohm coaxial cable between the RCA Jack.
S-Video: S-Video offers better quality than composite video does, and most video sources, along with the standard VCRs now have S-Video outputs. Connecting with special multipin cable and plugs.
Video of three components: This high-quality options is a minimum standard for connecting high-definition cable and satellite set-top boxes and progressive search DVD, Blu-ray Disc and HD-DVD player. There are three ohm 75-coaxial cables for the same type used for composite video.
VGA (Video Graphics Array): This high-quality analog RGB port is mainly used for connecting computers.
DVI (Digital Video Interface): One of the best kinds of inputs. This digital video connections can be connected to the devices with HDMI outputs (see below) through the adapter. It May also be used to link computers. This requires a special cable and multipin outlet. In some scenes with DVI inputs can work only with computers, so if planning to connect HDTV sources, such as digital HD decoder or a Blu-ray or HD-DVD player. All you need for HDTV compatibility is guaranteed accordance with HDCP (High-bandwidth Digital Content Protection).
HDMI (High-Definition Multimedia Interface) and the highest quality, it’s basically DVI plus digital audio and control link. Attract great is that you wire the pumps that HD content of your second home-theater components. This link is on almost any HD satellite receivers, HD cable boxes, and upconverting DVD players (one at 720p, 1080i, 1080., Or exit on a regular DVD), and this is the standard video connector for the Blu-ray and HD — DVD players. The exact text of the HDMI (for example, 1.1 or 1.3), there is little interest in TV currently on the market. If you have or plan to Blu-ray or HD-DVD player, is desirable but not essential, that the TV HDMI inputs are capable of receiving signals 1080p (which will arrive in 1080. Half). You do not have HDMI components? No sweat ga: Simple turn HDMI adapter for DVI connectors. Finally, on what is good, film and television studies of love, because it contains HDMI HDCP to combat piracy.
Important Order
Non-CRT display, as LCDs and plasma, its fixed-pixel array, which means that the rows and columns on the individual elements of that image, and prohibit the necessary habits of light. The resolution is calculated as the number of pixels per columns number of rows of pixels - 640 x 480, for example, or 1280 x 720. The resolution, and some lesser extent, to determine contrast ratio of the observed detail of the images.
Digital content is delivered in one of five options: 480., 480., 720p, 1080i and 1080p. At 480. is the same format as the standard analog television, and it was originally in 480. Programming is the adoption of digital cable or satellite in the house, leading to size. DVD-and sometimes the knee in the 480., 480. and usually progressive search DVD player can deinterlace 480. DVD create 480. output, however. At 1080. and 720p formats used by satellite, cable and over-the-air broadcasting high-definition content providers, as well as a large number of advanced DVD players upconvert to 480. and 480. content. Blu-ray and HD-DVD discs capable 1080. video, but the proper players can deliver content in the 720. or 1080. format for display, which can not be accepted 1080. entry.
It is generally regarded as a representation of high-definition screen pixels as a whole and has a total of close to 1 million. So, 1920 x 1080 (1080p), 1280 x 720 (720.), 1366 x 768, 1024 and 1024 are all examples of high-definition resolution display.
Important: Screen
Size matters, not us wrong. But just because you can afford 65-inch monster that does not mean that you should buy. You must be a factor in the screen if you plan to watch on television. After your nose pressed against each other in the cabinet smet?k one room is almost “ideal situation.”
To determine the optimal viewing distance, and therefore how much space you’ll need in your TV room, remember this simple little matiky: Note screen size in inches and multiply that is 2 Calculators ready? Take, for example, a 52-inch set. Sweet spot for viewing is 104 cm, or slightly more than 8.5 metres from the screen (8.66666667 feet, if you want to be nitpicky). May they not be exactly the target group. Just bear in mind if you think that is the place where your new series.
Important: “built-in tuners
Most of the current flat-panel display with a tuner for conventional analog broadcasting and cable television and broadcast HDTV reception. Some are strictly business - that monitors and non-in tuner (more than the usual plasma on LCDs). That would be, whether you have all of your television programs via satellite or cable, but if you want to watch television via satellite dish, make sure that the file you buy a TV tuner. Many are also built-in digital tuners for cable television. Although these tuners are the standards for the treatment of scrambled premium channels (such as HBO), sets no longer support the ga, to be sure you know exactly what you get. If you want power, make sure that the files you’ve chosen, and CableCard slot, which cable provider can give you the necessary electronic ID card. Cable pay-per-view and satellite TV currently requires an external set-top boxes.
Less: comb filter type
COMB filters needed to separate analog TV color and brightness information without losing too much detail, but this is not a problem in HDTV. The only way to comb filter comes into play for the analogue TV signal reception in the coming via composite video connection. For all other roads are in the loop. In any case, a comb filters, flat-panel TV are normally very well these days.
Flat screen TV-shopping tips
Well, you have already arrived. Here are the main points to consider before the adoption of HD car.
Consider the possibilities: If you can live with a theoretical found that 10 to 18 inches deep instead of 4 - 7, LCoS (liquid crystal on silicon) and DLP (Digital Light Processing) rear-projection sets can bring a solid performance in comparable screen sizes, and lower prices. They simply do not hear much because they are not as sexy.
To learn more about the next big television screens, Ga to “How to Buy Rear Projection TV.”
Think HDMI: If possible, you can set with HDMI (High-Definition Multimedia Interface) for the listing. This will ensure maximum compatibility with HDTV sources, such as HD digital cable boxes, satellite receivers HD and Blu-ray Disc and HD-DVD player.
Compare show using different materials: Just about every flat-panel displays will handle DVD and HDTV signals, but the average cable and satellite signals will give some of them. Nekupujete decision solely on the basis of images generated virgin resources.
Look for good black: In comparison, a DVD movie with a few low-light night scene. Ga use to ensure that there is a good black reproduction and the ability of information in near-darkness.
To familiarize with the remote: good remote control for your best friend, the poor, remote control of your greatest enemy. (No, well, we overdo a little, but you get the idea.) Includes retrospective or glow-in-dark buttons to help you find what you do when the light is rejected? How ga is often easy to find uses buttons?
See the video settings: Now you have the remote, pull the video adjustment menu and view of the institution. If you thought that the situation looked a little (or authorities) on the first viewing, try to choose the middle adjust contrast, brightness, color, tint and sharpness. This will probably not optimal, but it is possible that they are closer than they were originally found. A good show is simply worse than it looks less like bad. Repeat the test using different sources, including film, a little light, if necessary. Also keep in mind that you need color for each source. Most HDTV these days to have input into memory, so it is necessary to set up an ideal place for high-ret films at the entry and video games to the other.
You’ll find the latest prices for both LCD and Plasma TVs in the shop, PC World and compare the center.
