HDTV Installation

The decisions needed with HDTV are more complex than those that were necessary with the former technique. It is important to correct this information, or get our entertainment system, will be called into question.

Video Module

An ideal size is considered to have HDTV distance from the viewer on the screen that is about 2-3 times the width of the screen. Choosing the right size screen is one of the most important decisions when buying a new HDTV.

Most consumers say that theywant a wall-mounted HDTV. Say, however, according to the NPD Group, consumer and retail market research information company (NPD.com), only 13 percent of the current LCD TV owners and 25 percent of plasma TV owners installed their unit on the wall.

"Consumers are flat-panel technologies for wall-mounting capabilities drawn, but the difficulty of such a system often leads to explore alternatives such as standing or intermediary facilities." said Ross Rubin, director of theIndustry analysis, The NPD Group.

It is tempting to delegate the decision-making to a local vendor. This is not wise. Studies show that many of the seller at your retailer not as knowledgeable or neutral, as we hope so. For example, one study found that 37% of the sales team shunned Customer plasma HDTV systems because of the "in the plasma display was burning" when burning eliminated as a problem several years ago (JD Power and Associates). The studyConcluded that the sellers steered customers to the more expensive LCD systems.

"Watch TV buyers, mass merchants, it is possible to obtain the survived with a favorable price and may not expert advice. However, television buyers should be aware that the lower prices they find at mass merchants are mainly the fact that most of these transactions to the second category brand TV rather than carry major brands such as Sony or Panasonic. If the price of a particular model of televisionis compared, for each type of retailer, the prices are remarkably similar, "JD Power, Larry Wu.

HDTV video format: 1080p, 1080i or 720p: the higher number is better, right? Although technically 1080i has higher resolution, it is not the obvious choice. Most networks have opted for the 1080i format, because it offers higher resolution, while ABC, Fox, ESPN, and National Geographic Channel, the smoother the images are selected from 720p. 1080i is interlaced deliveredFormat (the "old" format), which means that your TV set draws each frame in two passes: once for the even horizontal lines and a second pass for the odd lines.

The 720p (progressive format is the standard in Europe) less lines of resolution as 1080i, but delivers images that are slightly softer look than the interlaced image, especially when a lot of movement on the screen, such as sports.

The new king is 1080p, which the best of both worlds. Progressive Scanwith a higher resolution. Little programming is currently in 1080p, but 1080p systems should be able to convert 1080i source material into a 1080p image.

Source of Programming

One of the options was to buy a DVD player, a lot easier recently. Blu-Ray became the de facto choice with the withdrawal of the alternative, HD-DVD. The other option, which must be made is: satellite, cable or terrestrial programming.Is a fourth choice, IPTV, television over the Internet can not be summarily dismissed.

More than 100 million U.S. households can receive from their HDTV cable system, and all of the top 100 cable markets in the country available HDTV programming. Unfortunately, most of the leading cable provider only a few of the 50 + HDTV networks. While HDTV local channel selection is generally better than cable satellite, the major satellite companies offer more national HDTV channels than mostevery cable provider. By 2010, 60% of U.S. households use a satellite signal, up from 15% in 2002.

IPTV is not available throughout the country. Currently, if it is available, IPTV offers usually around 25 HDTV channels.

Audio Subsystem

The audio component of the HDTV system is very important. George Lucas (Star Wars) once said that audio is half of the movie viewing experience. Most HDTV programming now includes more than two channels (stereo) audio. Most popularProgramming in Dolby Digital 5.1, which encodes five channels at full bandwidth, and a subwoofer channel (for the earthquake effects).

Surround speakers would be two front speakers contain as much distance as possible from the monitor, two speakers on the back of the room, a center channel above or below the TV, that provides most of the dialogue, and the subwoofer on the floor for the low-frequency bass. Subwoofers are multidirectional, so you can put it anywhere in the --Room.

If we maximize the impact of our wall mount systems are, we want to use in wall and / or in the ceiling. This leads to a cosmetically challenging installation.

System interconnect (wiring)

The cable used is important, but it is important to know what they prioritize over the cable. It is spending for consumers with a large amount of money for cable, lead but for the wrong reasons, and still in a lower performance.

To take full advantageHigh-definition programming (HDTV), either coaxial component cable (red, blue and green, sometimes referred to as "RGB")), a Digital Visual Interface (DVI) cable, or a High-Definition Multimedia Interface (HDMI) cable is required. This is in contrast to the red, yellow and white composite (RCA) cable, or using the round-ended S-Video cable with standard-definition TV.

An HDMI is the preferred pick for the ultimate audio and video quality. Look at the back of the TV and you willSome options appear. Depending on the selected unit could, you have to buy these cables separately. Cables can be expensive. If you have large selection on the basis of price, you can be circumvented your choice with the need for separate cable purchase.

The cables are one of the details that may be poorly chosen and lead to an overall unsatisfactory experience. Details are important.

Installation Decisions

Choose the correct installation. This will be decided by theDimensions and shape of space. An ideal wall should be at least twice as wide as the display, because you should have a minimum distance for acoustic isolation for the front-channel speakers have. Choose a place where the ambient light, especially opposite minimized from the screen.

Some HDTV models, the manufacturers offer a special mount for your setup. Plan for about $ 250 for the bracket. If a system promotes "VESA compliant" or "VESA mount, VESA stands for VideoElectronics Standards Association, and the display is designed to increase work with VESA standard. If not, look at the back of the display and check the screw threaded inserts, to which a mount can be attached. A minimum of four screws inserts required. Tilt wall mounts allow the user to change the angle of the display, and can contribute to glare from ambient light.

A wall mount on an exterior wall is probably more difficult than the installation on an interior wall. Exterior wallsoften offer more obstacles, including the insulation, for interior walls. Exterior walls can be built with fire-blocks. These horizontal braces or blocks are found usually about halfway up the wall, and significantly increase the difficulty of passing the wiring from your device to the display.

Decide if the wires inside the wall or on the outside. They should not be in the power cord into a wall as they are against NEC (National Electric Code), except when performed by aProfessional electrician. When you install the cables on the outside of the wall, there are cable management raceways are available at your local DIY store, the lock on the wall with a blanket in place attached. If the wires are on the inside of the wall is a keyhole drywall must be executed, can saw or a knife to cut holes in the rock sheet.

A good idea is to give a molding to create to be used as a cover for the cables. When the powerCable (s) to be reduced outside the wall, then the reasons for the operation of the other (signal) wires in the wall. Select either a cable tray that matches the wall paint or covering. It looks very natural and will consider it to be easier than plug into the wall.

The right HDTV hardware, the best sources of the programs, an awesome audio subsystem, the proper electrical connections and well-chosen installation decisions leads to a great theater system. Now, given thePopcorn.
