A guide to buying your next TV

A guide to buying your next TV E 'was simple, when you purchased a new TV you looked at 3 basic things: the price, quality and size of the screen. A few items, all sets were approximately the same. Today, things are not so simple. Buying a new television can be frustrating and confusing. Progress is often a good thing, and in this sense, is the competition. Progress gives manufacturers the technology needed to produce new and innovative products, competition, and the forces to offer better products at lower prices. The consumer is the winner, but with the right one, we need to take a while 'evil. All this leads to more choices and options when buying a new TV. In addition to price, quality and size of the screen, mode television, the buyer must also consider Display Type, HDTV or SDTV, Sound Options, and Connectivity Components.The purpose of this article is to provide the basic knowledge is necessary before going to buy a new TV. You won? T be able to read the product descriptions and compare options unless you know and understand exactly what is available. So what? D keep it simple, to the point, and leave the complex, techno stuff for another time and place. Read this article, print it and bring it with you to find your new TV.The BasicsAnalog (scanning lines) vs. Digital (pixels): If you bought a t-time TV a big difference you should be aware of the use of pixel to produce an image rather than scan lines. Our familiar CRT televisions known as analog displays. If you use a scanning technology to draw the image, which consists of a series of horizontal lines on the screen. If you walk up to your CRT, you can see the horizontal lines that compose the image. LCD, DLP and plasma screens are digital, and the use of pixels to form the image. Pixels are a series of small boxes arranged in columns and rows. When viewed from a distance, appear as a solid image. If you spend close to an image produced by pixel, you can see the pixel structure, which appears as though looking through a screen door. When buying a CRT set, the number of lines that the game is able to affect the sharpness of the images (plus the better). The same applies to the digital display, the more pixels the image is clear and you can sit on the screen without the pixel structure always visible.Display Types (CRT, Rear Projection, and Plasma / LCD) CRT: CRT ( Cathode Ray Tubes) use a sealed vacuum tube on the screen at the front and an electron gun in the back. The gun fires electrons at the screen in a series of steps of drawing the image on the screen. CRT? S always offer the best image quality available, producing the image can be seen clearly at any angle of vision. In addition, their brightness and contrast higher than other types of display. They are also relatively inexpensive. The disadvantages are as CRT TVs are heavy and take up more space for projectors or plasma screens. Their screen sizes are limited to about 40?. Rear Projection (RPTV): RPTV sets are a great alteative to the standard CRT, since they take less space and can have very large screens. RPTV? The project the image on a mirror that reflects the retu to the screen. This greatly reduces the depth of the cabinet units, and allows much larger screens. RPTV? S can be analog or digital, the method of projection. There are 3 main types of projection methods CRT, LCD and DLP. CRT uses cathode ray tubes, as a direct view television, which can produce a bright, detailed images, but are heavy and take a little 'more space compared to LCD or DLP. The LCD method passes a powerful light source through transparent LCD chips. The image displayed on the chip is then projected through a lens and a mirror that reflects the image on the screen. Rear Projection sets using LCD? S tend to take less space than those using CRT? S, but usually costs a little 'more. Moreover, the image produced by the LCD panel is made up of pixels, which is enlarged when projected onto the screen. If you sit too close to one of these games, you will see what is known as? Screen door effect ", the pixel structure is often visible in the area. DLP is the latest and greatest technology projection. This acronym stands for Digital Light Processing, and uses micro-mirrors to reflect light in color on the screen. Since the light is reflected rather than transmitted by fleas that LCD, DLP projectors produce images whose contrast and color saturation can rival that of CRT based systems. They do so while maintaining the compactness and lightness of LCD systems. Of course, they are not cheap, but technology is never. The brightness and viewing angle, are among the most important factors to consider when examining RPTV? S. When measuring brightness, you want to compare the image from the screen, not the brightness of the projected image inside the cabinet. The intensity of the images will always be less, so make sure you compare apples to apples when looking at the specifications of brightness. Contrast ratio (the ratio between light and dark areas of the image) must be in the neighborhood of 1000:1 If this figure is too low, the image will be dull, and blacks seem gray.Plasma / LCD Plasma / screens LCD is the most versatile in terms of shoes Hoing a large screen in a small room. Plasma is usually less than 4? thick and can be hung on the wall, if desired. They provide an image with the adoption of a light source of high voltage across the cells that are composed of two layers of glass between which neon-xenon gas is trapped in a state of plasma. The gas is then electrically charged and reacts with the phosphorus, which produce the colors on the screen. LCD screens work by lighting a light source through an LCD chip which produces the image. Although plasma and LCD screens can produce beautiful, strong, rich color images, their contrast suffers slightly 'due to the fact that the light passes through the pixels. Blacks seem to be very dark shade of gray, compared to the true depth of the blacks who can not produce a CRT. A big advantage is the display on plasma and LCD RPTV? S is the angle of view. A plasma display has a viewing angle of 170 degrees (like a CRT) while RPTV? S and LCD? S are in general less. Recently, LCDs have made enormous progress in improving their off-axis viewing angles. Although not yet as good as a plasma or CRT, depending on your room configuration, once the major factor in May to less than a issue.Deciding What? S Law YouScreen Size: The type of display you buy will affect the size of your TV, you can keep in your room. Plasmas are most welcome any CRT? S take more space. Now that you know the types of screens available, you can determine the size of the screen to watch your current TV for.Evaluate: Decide the size of your new TV is one of the most important decisions that have to do. This will often help you determine how to display your new TV is. It 'much easier to buy a new TV once you know what type of display you are interested in. The best way to determine the size of your new TV is to start by assessing the current status. The size of the screen adequate, or if you want something bigger? What kind of TV, is managed View (CRT), or rear projection? It is expected to review the game, or should fall into the same space, you are now? How far you sit from the screen, and that the angle of the screen? One last note, and very important form - TV? And when we grow at home! So bigger is always better, but be careful not to be too big to buy a TV. If you go to one of the giant retailers to purchase or evaluate your TV in mind that the shop is a great place, and that even the biggest TV look smaller than they really are. When you get the original game for your tube, it seems much bigger than it was in the shop, I can guarantee that! The last thing you want to have a large box to dominate your room. In addition, a large TV in a small room it does not perform as well as that of SDTV or sized.HDTV: It 'really a personal decision and is based on the way you watch television and what you expect. While SDTV (Standard Definition Television) will be for most people, the amount of high-definition programming will increase in coming years. You can consider a set that is HD capable so that if you want to move to high definition in the future, television will be able to display high definition image.If you're the type who likes to watch TV and spend long before the set, then HDTV should be high on your list. They are the standard definition television in SD (480p) or high-definition HD (720p or 1080i). The numbers refer to lines of resolution that make up the image, while the letters refer to the way in which the image is drawn on the screen (p), progressive, and (i) interlaced). Interlacing requires two passes through the display of images, while progressive scanning draws the entire image in one step. Progressive scan is generally superior to Interlacing, as it produces a smoother, and flicker-free images. Most HDTV? S can display 480p, 480i, 720p and 1080i, but there are some that can only display HD signals in 1080i. You should find a series of display 720p and 1080i since the image can be displayed in its native format, instead of being converted to 1080i by the TV. High definition television sets are in 2 basic flavors, HDTV and HD Ready. The HDTV is able to set both the receiving and viewing an HD signal. It has a HD tuner that can receive digital signals in SD and HD. HD Ready sets are physically capable of displaying high-definition image, but not its integrated HD tuner. This means that you need to buy an HD tuner (receiver) to capture and send the signal to your TV. In this scenario, the television acts as a display, connected to the computer. Some people do not mind, because it allows them to combine the elements for a better overall quality. If you are a subscriber cable or satellite, you are using an HD receiver compatible with your system vendor. In this case, "HD Ready" can be a smart choice because they do not pay extra for an HD tuner that need.Aspect Ratio: The ratio refers to the shape of the screen. Unless you buy an HDTV, you'll have to decide which aspect ratio to achieve. Until now, the TV? S were all 4:3 aspect ratio or relatively square. All HDTV screens and many other mode TV sets are 16:9 aspect ratio, or rectangular in shape. This is a real sticky point since most of the programming is still a form suitable to 4:3. If you choose to buy a TV with a 16:9 aspect ratio, will artificially stretch the image to fill the entire screen. Even when you buy an HDTV, you must ask to see how all the equipment displays 4:3 programming in full screen mode. Some brands manipulate the picture better than others, and this May, a final exam in your purchase.Sound Options: Again, that lets you know what you expect from your new TV and how it intends to use. If you have a DVD player and tend to see many movies at home, you want a TV with Dolby Digital 5.1 Surround Sound. This is the standard audio format used on DVD? S and for all HDTV broadcasts. If the TV is integrated into a home audio system that has its own Dolby Digital Processor, you may not be affected by TV? S sound capabilities. Dolby Digital audio with a DVD or HDTV signal can be achieved through optical or coaxial digital cable. You should check your DVD player to confirm the type of connectors to ensure that your new television host it.Connectivity: This may be a po 'of technique, but it is very important to determine how the new TV to integrate with other components hours and in the future. Again, if you are not conceed with HDTV then your choice is simple and much less crucial. Most of the TV? S are more than adequate number of items to allow you to connect any device. In the video, you must ensure that, at least it has Component, S-Video. For audio, some groups have optical connections, while others have coax. One of them is fine, but Optical cables have an advantage because they are not affected by electromagnetic interference. When you think about HD components things get a little 'more complex. The method of connecting to an HD source component such as a satellite / cable to your new HDTV is known as a DVI (Digital Video Interface). This connector looks a little 'as the VGA connector to connect your computer monitor. You can use Component DVI connectors, but this is preferable because it has very high bandwidth, and also keep the signal in digital format. There is a considerable increase in image quality when viewing HD via a DVI connection. A more recent connectivity is better than DVI is HDMI (High-Definition Multi-media Interface). HDMI is a connection similar to DVI, but goes further by carrying both HD video and audio over a single cable. It will be very popular because it reduces the cost and complexity of connecting HD components. HDMI is supported by many new products, and is currently available on HD satellite receivers DISH Network and DirecTV, as well as many new DVD players.Conclusion: Well, what? It. Having a good knowledge base will make your purchasing decision easier and more fun. Whatever your choice, try to keep an open mind and think about the future. Do not be afraid to spend a little 'more now, you can save a lot in the long term.
