Listening on the transmissions of emergency service providers has been a practice of criminals, reporter, and the curious for years. The scanners which they all use to eavesdrop are simply radio receivers which are capable of tracking hundreds of frequencies not normally available to the casual radio listener.

While those who just want some excitement on a lonely Saturday night might like to listen for the latest cops-and-robbers scenarios from the safety of their living rooms, there are many people with far more sinister motives using radio scanners to keep track of what law enforcement is doing.

But not only law enforcement agencies are relying on private radio communications; other emergency services and corporations use high frequency communication to keep private information private. In an effort to thwart the rising number of people with radio scanners who wish to intrude on their communication, they began to adopt digital broadcasting. This approach reduced their problems for a while, but eventually more than one electronics manufacturer realized that had a potential new market existed, and began producing a digital radio scanner.

APCO Project 25

After 9/11, the Association of Public Safety Communications Officials introduced APCO Project 25, an attempt to reserve a spectrum on digital frequencies for law enforcement and emergency use. They are deliberately chosen to be available to first responders in emergencies or for transmitting sensitive information. But the digital radio scanner has made them as accessible to the listening public as the old scanners made the high frequency broadcasts. A digital radio scanner is available for purchase online or at numerous brick and mortar electronics stores.

Encryption

In the post 9/11 world, the US government is becoming ever more concerned about its security, and the digital radio scanner is under scrutiny in government circles. Although some civil liberties advocates have defended the right of the public to control the airwaves, digital and otherwise, in some parts of the country law enforcement agencies have simply chosen to avoid being scanned by encrypting their broadcasts.

While more than one digital radio scanner is capable of demodulating some digital signals like those of APCO Project 25, any digital radio scanners designed for signal decryption have been legally banned. Violations are punishable by jail time, fines, or both. And some US states have passed laws making it illegal for any one convicted of a crime to have either a digital radio scanner or the traditional variety.

This year alone sales of HDTV is expected to reach 20 million. In fact, HDTV sales is on track to increase all the time especially during major sporting events, as fans to want to enjoy the big game in all of its high-definition glory! HDTV comes in different prices and sizes. Whether it is DLP, LCD or Plasma, the choice can be overwhelming. Consumers are often confused on what to buy because of their unfamiliarity with the technology.

Studies show that nearly 60% of HDTV buyers are not sure on the difference between LCD, Plasma and Micro Display. Many HDTV shoppers do take time to research but still need to be guided on which product is appropriate for their demands and budget. A HDTV Buyers guide can make this easier.

Cable companies have strengthened the demand for HDTV, as there is already 17 channels that offer HD programming. In addition, HDTV prices have sharply dropped over the past year and some sets cost as lows $1,500.

Comcast has reported that its roster of HDTV customer agents has ballooned to 1,100 and they answer queries and take orders from subscribers. The company has also deployed 1,100 HDTV technicians to assist in setting-up the products at homes.

Terms of HDTV

HDTV – A new breed of TV that combines the capabilities of a HD-tuner and HD-ready display. Nearly all HDTVs’ sold in the market today use the 16:9 widescreen aspect ratio. An HDTV tuner can still receive analog and digital broadcasts over-the-air.

HD Compatible TV- These sets only consist of the high-resolution display. They can only accept digital broadcasts if hooked with a separate HDTV tuner. HD-compatible TVs can have the 16:9 widescreen ratio or the squarer 4:3 aspect ratio.

Starting on HDTV

A recent study by the Consumer Electronics Association indicated that 71% on consumers it has surveyed plans to purchase an HDTV set soon are already planning and saving up. However, one reality in the consumer market today is that stores do not have the right number trained salespeople that have a good understanding on the new technology.

Most are more concerned on making a quick sale rather than making it easy for the consumer to understand what he is going through. Translating or explaining complicated technology terms is never an easy task. This is where specialised buying guides to HDTV can be invaluable and save you hundreds in buying the wrong type!

This is where a specialist HDTV guide will help and potentially save you hundreds of dollars in buying the correct setup. It’s hard enough to explain the difference between HDTV and analog TV and it is even more difficult to clearly tell the difference between HDTV and EDTV.

Setting up HDTV

When you decide to jump into HDTV give yourself time to become familiar with the technology. An HDTV setup normally consists of the following, HD-ready TV, receiver, antenna and HDTV service provider. Many HDTV’s nowadays already have a built-in tuner, removing the need to purchase an independent box.

Receiver

The DIRECTV HR10-250 High-Definition Television satellite receiver is ideal for those that want to get the most out of watching crystal-clear HDTV broadcasts. The HR10-250 can receive and decode digital signals from DIRECTV’s high-resolution broadcasts. The satellite receiver also features a built-in hard drive digital video recorder.

HD-broadcasts feature images rich in detail and surround sound makes a room alive and vibrant. HR10-250 HDTV satellite receiver can be connected to any HD-ready TV and home audio system.

If you are in the market to buy a HDTV, then I would recommend that you research as much as you can. HDTV Buyers Guides can be very useful to give you fuller explanation on what to look out for and what to avoid!

Until not to long ago, ambient light was the main argument you had in choosing LCD over plasma. With today’s models, though it remains a factor that helps you decide which technology to choose, it is not as decisive as it was before. The light can affect the picture quality in two ways.

First of all, if the screen material is highly reflective a lot of light will bounce from it. In a real life scenario this happens in a sunny day when a lot of sunlight enters the window and hits the screen from an angle that makes it reflect directly into your eyes. In this situation the screen acts as a mirror and instead of seeing what it is displayed on the screen you see that annoying light that reflects from it. This happens because the amount of sunlight that hits the screen and bounces from it is much higher than the amount of light the screen produces. Depending on how reflective the screen is and the angle from which the sunlight comes, this effect can be more or less disturbing. Same effect appears from other powerful light sources – like your light bulbs – but it is less disturbing. In most cases the light from light bulbs is very weak compared to sunlight so this effect is either invisible or almost unnoticeable.

The second way in which light affects the picture quality has to do with your eyes not the TV. Your eyes are built in such way that they adapt to the amount of light around. When you watch TV in a dark room, most if not all light that enters your eyes is coming from the TV. In a well lit room a lot of the light that your eyes capture is ambient light coming from the window, light bulbs or reflected by the walls and objects in the room. In this situation your eyes get more light from the environment and less from the TV itself. So when you watch TV in darkness the picture quality looks better because your eyes capture all the light from the TV and you perceive a better contrast, luminosity and saturation – which are the most important factors that affect picture quality. When you watch TV in a well lit room the ambient light will overlap with the TV light and it will make it look more washed and the colors will be less intense.

Generally Plasma TV screens are more reflective than LCD screens. At the same time, a plasma TV tends to offer better picture quality than LCD TVs in an environment with controlled lighting (a dark room). Because of these characteristics of plasma and LCD TV, they are recommended generally for different situations – plasma TVs for people who watch TV with lights turned off or dimmed and LCD TV for people who watch TV during daytime and have a lot of light in the room. If you have an averagely lit room then both TVs perform similarly.

There are exceptions however. Technology is evolving and plasma TVs now have an ace in their sleeve. To find out what is the plasma TV feature that makes them perform in a well lit room at a level comparable with LCD, follow the link titled Plasma vs LCD TV at the bottom of this page. The guide you will reach through that link has much more useful information about plasma vs LCD TV subject and can be a very useful resource if you want to understand which is the best HDTV for your particular needs.

It is hard to imagine television without a remote control. Channel surfing really wouldn’t be the same without them. Unfortunately, losing or breaking a remote before the demise of the television isn’t unlikely. It’s also probable, with the multitude of remotes lying around the average living room that an owner will decide to consolidate just for the sake of their sanity and get a remote that can control not only the television but other equipment as well.

Before television owners begin shopping for a new remote however they should consider how much they really want to spend. A very basic television remote can be had for around $12. On the other end of the spectrum, spending in the neighborhood of $1,000 is also possible.

Most television remote controls are IR/infrared, meaning that they communicate with a television via an LED which transmits an infrared signal. In order to function properly users must generally be within 30 feet and within line-of-sight of their television. These remotes won’t be able to transmit the necessary signal to the television through a wall or around a corner no matter what the distance although in many instances this is not a concern to the average user.

Some satellite TV receivers, stereo systems, and home theater components use RF/radio frequency remote controls which communicate with devices via radio waves. RF controls have a greater range than IR controls. RF can transmit up to 100 feet away and offers the added benefit of being able to transmit through walls. One way that an IR remote can be “boosted” to allow it a greater transmitting range is to get an “RF extender”. This does not change the fact that a person is using IR, it just gives them greater range.

If a person’s goal is to consolidate their television remote with other AV remote controls then a universal remote should be considered. These remotes are capable of operating multiple devices, even those from various manufacturers. Very handy, but they will have to program in the command codes of each piece of equipment they want the device to control. Information on command codes is generally found in the owner’s manual for the equipment. To save time, a “learning” type of universal remote is an option. These remotes are able to read signals transmitted by other remotes and to then begin transmitting those same signals without the user having to program the command codes.

A common complaint about the average television remote is that it is hard to use in the dark. A back lit keyboard can be useful in this situation. Another issue can be the difficulty of using a remote because of the sheer number of buttons on the face of it. A couple of options can help to address this issue. Some television remote controls use “macro commands” which allow the user to perform a series of commands with the push of a single button. For instance, a macro command could be set up to turn on the television, the DVD player, initiate play, turn on the speakers, etc. by hitting a single button. Remotes with LCD screens can also cut down on the number of buttons by displaying a limited number of icons on the display versus having a button for every function.

Television remotes today even offer various methods of input aside from pushing buttons. Touch screens, joysticks, and even voice command controls are available; for a price. Touch screens can be color or grayscale; grayscale of course helps hold the cost down. Higher priced remotes offer two way communication which allows the remote to pick up and display information from the device that it operates. For instance, such a remote could display information about the programming on a particular television channel while viewing other shows.

Like all electronics for the home, television remote controls are beginning to multitask and understanding all of the features takes a bit of research. Buyers simply need to assess what functions are important to them and how much money they really want to spend.

Rome wasn’t built in a day and neither are good Home Theater and Audio Systems. Hopefully this article will save you time, money and aggravation.

This is how I put together my Home Theater and Audio Sound System and you might want to use this as a general guide in terms of what I learned through trial and error. The first part of this article is general buying tips. The remainder of the article is arranged in alphabetical order by topics beginning with Audio/Video Receivers and ending with Tweaks. Thus you can scroll down in order to find DVD players come after CD players, etc. As previously mentioned, this article is intended as a general guide written in layman’s terms not technical terms trying to summarize Home Theater and Home Audio basics. Onwards and upwards.

Buying Used or Refurbished Items

My rule of thumb with buying something used online is: 1.Make sure it comes with the original manual and remote control, which will make reselling it, should you chose to do so, easier. 2. Make sure it is described as in very good or better condition from a seller in the US (or the country you reside in). 3. Pass on any item which the seller has described previous problems with., 4. Do not buy anything listed “As Is” or “No Returns” as it basically says your stuck with this once you pay for it even if its DOA. 5. Only buy from someone with a lot of feedback whose positive percentage is 95% or better. As a rule I won’t buy from anyone with feedback of 10 or less, if you’re putting up $200 or more, I’d increase that to 20. Even if you do pass up some legitimate people in the process with that rule, the chances are good that the item will show up again within the next 2 months or so from a seller with feedback of 20 or better. What I’m saying is, don’t rush things when you don’t have to. Also pay by paypal only. This way if there is a problem, paypal will help resolve it and/or get your money back.

What Not to Buy Used or Refurbished:

Do not buy a used or refurbished TV under any circumstances. You are asking for trouble if you do.

Do not buy a used or refurbished DVD player, Universal player or DVD recorder under Any circumstances. These are made with a limited life in mind.

How to decide what to Buy

If you’ve heard or seen any system personally that you liked, I would go by that first to decide what to buy. What I wouldn’t do is go to a store & make your decision based on what you hear or see there. In many cases for instance, the HDTV’s are not actually showing HD shows in the store because they’re not receiving HD signals or the sound system is giving lousy sound because of bad acoustics, bad ambience and improperly set controls which the salesman is pretending to not notice. Should you ignore all that, let the buyer beware, at least bring a CD and/or DVD of your choice to sample their system, not the stores generic ones.

I would go to Forum sites and see which components or system, are constantly being praised and then read Online Reviews and information from the Manufacturer and base your decision on that. Likewise use the forums to ask about a specific product.

Audio/Video (A/V) Receiver

Most of the basic features on 7.1 or 5.1 A/V receivers are similar, no matter how old the receiver is. Before I go on, you can get 5.1 sound (5 speakers and a sub)on a 7.1 receiver and most of the receivers in the last 5 years or so are 7.1. You can get very good used receivers online for, 40 to 70% off the listed retail price when that receiver was new, complete with a remote and manual. Again, research any receiver, from a friend’s opinion, a forum, manufacturer information & online reviews. I myself got a Denon A/V 3801 Receiver which I love for around $380 including shipping that came with the Remote and Manual. As I had a Universal Remote and knew I was going to keep this receiver, I sold the remote for around $35 online, so all I spent was $345. This receiver cost over $1100 when it was new. On a lot of these receivers, you are just paying for extra bells and whistles, which if you don’t need, can save you on money. For instance, many of the newer receivers come with built in EQ/DB systems, that will automatically set up the receivers & these cost a lot more then systems which you have to do this manually. Note, I listen to CDs on the Denon’s All Natural 5.1 Stereo Sound which plays CDs from all 5 speakers and my subwoofer without reprocessing the sound. To me this gives my sound much more depth. Other people do not like to listen to CDs that way.

Cables

You will need good cables to get a good sound and picture: These cables include: Fiber Optic Cables to get 5.1 sound from your HD Receiver/DVR and DVD players. You will also need Analog RCA Cables to get good sound from your CD or Universal Player. You will need 2 sets of Component Cable to connect your DVD player to your TV and HD Receiver/DVR to your TV. Finally you will need a subwoofer cable and speaker wire.

If you get your HD service from a Cable or Satellite Company, usually they give you free component cables. Do not use these as they’re not all that great on the average and buy better component cables. Cables are not built the same and will produce different results, contrary to general opinion. I use standard Monster component cables, Monster Standard THX Subwoofer cable, glass optic cable which gives a more upfront revealing sound in my opinion for my DVR/Receiver & standard optic cable for my DVD player, speaker wire, and believe it or not, 2 cheap pairs of Acoustic research analog cables which I find the most neutral and least likely to reveal a recordings weaknesses!

CD Player

This is the component I have upgraded and changed the most as believe it or not, the sound differs greatly between players. As mentioned above, unless CD sound is not that important to you, do not use a DVD player to plays CDs.

I’ve personally found that many vintage CD players which you can find online generally give fantastic sound and are relatively cheap. I had a Pioneer Elite 59 CD player for many years that one could get between $150-$250, that produced great rock sound.

I’ve found buying a CD player is a total trial and error proposition. Depending on the audio equipment on hand, the person and the music they like, one man’s Heaven is another man’s hell. Many people, myself included, have bought CD players based on great forum comments and/or reviews only to be disappointed when they actually listened to them and then resold them the next day or week online at a loss.

My current CD player is a Jolida JD-100A Tube CD player, which I love. I got it used for about $350 less then I would pay retail for. Tube CD player’s sounds change greatly depending on which tubes one uses. Again, this is a trial and error Preference. I currently am using 2 ECC83 12Xa7 Tubes.

DVD Player

I have a Harmon Kardon 31 DVD player which I bought online for about $50 less then the retail price, when it first came out. I chose this model because of the reviews I found online which raved about its great sound & excellent picture.

I do not use my DVD player to play CDs because in my personal opinion and those of many other people, CD players produce better audio sound. So if the sound of a CD is important to you, buy a CD player separately and ignore the company BS line that there is little sound difference between playing CDs on DVD players instead of CD players.

DVD Recorders

There are 3 types of DVD recorders: Internal computer DVD recorders, external computer DVD Recorders and Stand Alone DVD Recorders that you can record TV Shows on. The main difference between the stand alone DVD recorders and the computer Internal and external recorders are that the stand alone DVD Recorders can not as far as I know record 5.1 sound while internal and external computer DVD recorders can. While stand alone and external computer DVD recorders are relatively cheap, they usually don’t last more than a couple of years before their lasers break down. The good news is, they’re relatively cheap to just buy a new one. My internal computer DVD Recorders have never broken down. You do need software to record DVD’s on your computer and a lot of these players come with it. I use Nero which I love and which is also good for burning CDs as well. One important thing to know is that most commercial DVDs are encrypted as to prevent DVD copying using standard commercial software.

HD DVR/TIVO

My HD DVR is provided for a rental of about $10 a month from my HD service. I am very happy with my set but I really am not qualified to make any recommendations on these.

HDTV

I have 2 widescreen HDTV’s which I love, a Panasonic 34″ set and a Mitsubishi 48″ set, both of which I bought new. I would not recommend buying an HDTV set used. I also would take an extended warranty for the maximum length so you don’t have to worry if something breaks down. I made my purchase decision on these sets based on what I read online in forums and reviews as well as manufacturer information. You usually can get great discounted prices both from retail discount electronic chains as well as online discount electronic companies including extended warranties.

5.1 Headphones

I didn’t realize in my wildest dreams these actually existed and worked until I did a Google search and wound up at a forum where people all raved about the relatively expensive, Pioneer SE-DIR800C HDPH Dolby Digital 5.1 Wireless Headphones, which I got new for $300 online $100 less the retail price. These headphones are my Holy Grail, I don’t know how Pioneer does it, but they produce incredible 5.1 sound and I’m not aware I’m listening through headphones! These are furthermore, wireless and work terrific, I’ve never experienced any Static noise or interference. To me these headphones are in a class by themselves with no peer. I use them for TV and DVD by Connecting my receivers optic digital out to the Pioneer’s Wireless Station’s Optic Input. My best electronics purchase ever.

MP3/IPOD Headphones

For some reason, most of the free headphones supplied with Ipods/MP3 players, suck. Meaning, they are uncomfortable or lack something in sound or both. For myself, I found I could not tolerate earbuds, headphones which like hearing devices get attached to the inside of your ear. I wound up buying at a great online price, a new set of over your head, Koss Porta Pro headphones which were super light and comfortable, stayed over my ears and had good though not great sound, for about $15 less then I would have to pay, retail. Again, I bought these based on forums, reviews and company information.

MP3 Players

Sorry I’m not going to be much help here, as I only use my MP3 player for jogging and working out and as such I use a Creative Zen Nano 512 Plus as its super small and light and has great sound.

Speakers

I use my 5.1 speaker system for DVD, TV and listening to CDs. I feel my system, which is an Orb Audio Mod 1 5.1 speaker set-up (5 speakers & a subwoofer) bought new, has great sound for all of these. Other people prefer to use 5.1 speakers only for DVD & TV and listen to CDs on different speakers. I discovered Orb based on finding an incredible amount of positive reviews on them in forums and based my buying decision solely on that.

Tweaks and Accessories

This is another hit or miss proposition. I bought online a new Musical Fidelity X-10 V3 Tube Buffer for $250 and it improved my CD player sound when connected to both my current, Jolida JD-100A (Tube) CD player and my previous Pioneer Elite PD-59 Solid State CD player. I purchased the X-10 V3, Tube buffer again from forums and reviews as well as company information.

Wireless TV headphones are not cheap. This is for several reasons. For one, they are not as popular as other consumer electronics such as DVD players or MP3 players. Manufacturers have not been able to achieve the economies of scale necessary for dramatic price decreases. Second, the TV headphones must be designed to stand up to constant wear and tear. Young kids will be one of the primary users and children are notoriously rough with their possessions.

Since in many ways they are a “niche” technology, retailers in the past could extract good profits from the product. They could stock a very limited selection with only one or two models (never the cheapest ones) and force the consumer to pay more. Many times the retailer with the best selection would be high-end electronic boutiques, which would offer a wide but very expensive selection.

Fortunately the internet has really decreased prices dramatically because of increased competition. There are now a plethora of online retailers that stock wireless headphones. This is because they are a relatively easy product to sell as they are not perishable (such as flowers) or difficult to ship (such as furniture).

You should seriously consider purchasing TV headphones online as they are usually significantly more expensive than in a regular store. Retailers know they can get away with jacking up the price. If you want to get the best price the web is really the best place to go. Some online retailers offer free shipping and good return policies as well.

I think by now you should know that PSP has many usages, it is not only a portable games console but you can play movies or music on it as well.

TV channels on PC or laptops are here to stay. The questions to ask yourself are what are the benefits and do I want to watch it. In other words is it for me. You can have access to over 4000 and some suppliers advertise 6000 TV channels on PCs. When most people read this they think “what a load of rubbish, who can ever want that many channels” . However if you go through a process of elimination and ask yourself how many of those channels am I going to watch, you will find that even if you do not want to watch foreign language movies , children’s programs, arts, animal programs, if you watch TV at all you will still have access to more of that particular genre than what you have now.

Sport is always a good example, if you are interested in a sport that is mainly played overseas it is hard to get coverage, the rugby league world cup is going to be played shortly and many of the cable TV channels will not be showing it live, if at all, however with TV channels on PC you will be able to access it by watching overseas television programs. Some providers are now offering television from over 75 countries. This gives you the advantage of getting a different perspective on world news, world sport and if you are living abroad this is an opportunity to see some of your own movies, sport and news.

This works for minority sports and the main sports. The main golf tournaments are televised but do you get live coverage where you live, not always. Watching TV channels on PC or your Laptop offers flexibility that cannot be matched with a TV, if you want to quickly catch up with the news or the financial markets or see an update on your team you can look on your computer and be located anywhere. Certainly for people who are on business trips, holidays and out of town the chance of catching up on their TV shows is a great idea.

Once you decide there is an advantage in watching TV channels on PC you will want to know the cost. At the moment Satellite TV channels on PC are much cheaper than cable or sky TV and I believe it is only going to get cheaper. Not having to buy any extra hardware makes it very easy to access, there is no downside whilst waiting for the company to put up a dish and make any physical connections.

With the speed of the changes in technology your services will only improve and with competition prices will be kept down. A one off payment is the only cost you should incur. If you are asked to pay monthly charges you are being ripped off. This will entitle you to download the software immediately and again make sure you are being offered all future updates at NO cost. Already during this year alone we are seeing improvements to the quality of the picture and the extra options of radio channels and downloading your own media. TV channels on PC and Laptops is just the beginning, it is convenient, fun and allows you to choose your own form of entertainment.

LCD TV monitors are sleeker and they have better resolution than other monitors. This is because of their Liquid Crystal Displays or their so called name – LCD. An LCD monitor could produce 16.7 Million of colors which makes even the tiniest hues detected. They are sleekly designed and built for them to be able to occupy lesser space. They are light weight too which makes transportation easier.

LCD TV monitors are combinations of the usual computer monitors and television. They have tuners built in which allows them to function both as a computer monitor and a TV. They also have AV inputs which allow speakers’ and woofers’ attachment.

LCD TV monitors block unwanted colors from its white spectrum. Their screens have larger number of pixels, every twist and every turn produces an image. They give great angles for viewing. Some LCD monitors could also produce images of good quality when viewed in an angle of 170 degrees. Pixels are illuminated by one thin lamp or a projector LCD. Because of this, LCD TV monitors are very compact.

These monitors can also have screens that are non-glare which make them gentle on the eyes even if viewed closely. They are also not affected by light that falls onto them. The image quality of an LCD TV monitor will remain with the same crispness either in a dark room or a bright room.

The monitors are available in sizes 19″ to 21″, and 23″ up. Smaller LCD monitors are available too in sizes 14 and 17″. All of them provide good qualities of images regardless of their sizes. However, there are some complains, LCDs suffer from higher burn rates which mean that images persist on pixels for much longer times. Some LCDs also can’t run Hi-Def games that require HD compatibility, and some produce ghosting effects. However, improvements are being processed to make these LCD TV monitors perform better.

In keeping up to innovation, a new LCD TV monitor type is now being designed to allow watching different programs in the same TV through just changing the angle of viewing.

You have heard about high definition tv and see it advertised during your favorite sports shows. Your kids (and you) want a new Xbox 360 or PS3 and you want to make sure you have the right tv to get the most bang for your buck from your new toys. So you have decided that this is the year to take the plunge on a brand new, sleek LCD flat screen tv. That is all well and good, but what do you do next? You are lost in the alphabet soup of LCD, HDMI, 1080p, 1080i, 720p. You are in over your head with technical terms like refresh rate, contrast ratio, and milliseconds of response time.

The following will give you a quick, straight forward road map of basics to consider in order to make your LCD flat screen tv purchase a success.

Cost considerations – You need to know how much you are willing to budget for your new LCD tv. Determine if your budget is bare bones minimum or price is no option. Most likely it will be somewhere in between. A new LCD can cost anywhere from a few hundred dollars for a small LCD for your kitchen or bedroom to several thousand for a LCD flat screen for your primary tv in your home theater room.

The cost of a new LCD for a home theater room in the past was price prohibitive. Although an LCD will still cost a bit more then a comparable Plasma it is interesting to note that over the past year the gap between a new Plasma tv and an LCD has shrunk.

Screen Size – Is this a small tv for a dorm room, a bedroom or the kitchen or is this a primary tv for a home theater? Being partial to home theater I would recommend that the tv be at least 46″ to make the greatest impact. A larger tv will enhance the feeling of immersion of a movie or a sporting event. LCD flat screens of sizes ranging from 46″ to 52″ are becoming more common with sizes of 60″ or more as an option although the cost is still a drawback for many.

Resolution – In order for a tv to be considered high definition, it needs to be able to display screen resolutions of 720p or 1080i. The newest standard is 1080p which allows you to view the highest resolution content found in HD-DVD or Blu-ray or experience the newest video games in all their glory. It is important to point out that it is very difficult to distinguish a difference in picture quality between a 1080p picture and a 720p picture at smaller screen sizes, so before shelling out the extra dollars make sure that it will make a difference in picture quality.

Video inputs – Make sure that your tv has plenty of video inputs to meet your current and future viewing needs. HDMI is quickly becoming the standard video and audio input for high definition so make sure the tv has several HDMI inputs along with the standard composite and component inputs.

Picture quality – Of course none of the issues above make a difference if the tv has poor picture quality. There are a lot of things that come into play when considering picture quality.

One of the selling points of the newer, upper tier LCDs is the 120Hz refresh rate, which is double the normal refresh rate generally allowing for smoother transitions and screen images in fast moving movie scenes and sporting events.

Specifications alone do not always tell the whole story. For example, a contrast ratio can be helpful, but keep in mind that there is not a clear, standardized measurement for contrast ratio between manufacturers. A contrast ratio within a product line is generally more helpful then when compared between manufacturers.

Look at whether the LCD flan screen tv can produce vivid color, deep blacks, realistic textures, detailed images and smooth screen transitions.

With a little research and planning you will soon be enjoying crisp, clear, vibrant images on your new LCD flat screen tv so kick back in your home theater lounger, gather your family and friends around and enjoy the show.
