A cathode ray tube or CRT, is traditionally used in most computer monitors and the advent of plasma screens, LCD, DLP, OLED displays, and other technologies. As a result of CRT technology, computer monitors continue to be referred to as "The Tube". A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screenful of images.
A Liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices.
A plasma display is an emissive flat panel display where light is created by phosphors excited by a plasma discharge between two flat panels of glass. The gas discharge contains no mercury a mixture of noble gases (neon and xenon) is used instead. This gas mixture is inert and entirely harmless.
The glass panels seem to be vacuum sealed, because when they are broken the plasma breaks up, seemingly from the addition of air to the space.
Surface-conduction electron-emitter display (SED) is a flat-panel, high-resolution display. Some SEDs have a diagonal measurement exceeding one meter (approximately 40 inches).
The SED consists of an array of electron emitters and a layer of phosphor, separated by a small space from which all the air has been evacuated. Each electron emitter represents one pixel. The SED requires no electron-beam focusing, and operates at a much lower voltage than a CRT. The brightness and contrast compare favorably with high-end CRTs. Prototype electron emitters have been developed with diameters of a few nanometers. SED technology can offer unprecedented image resolution.
Digital Light Processing (DLP) is a technology used in projectors and video projectors. In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micromirror Device (DMD). Each mirror represents one pixel in the projected image. The number of mirrors corresponds to the resolution of the projected image: 800x600, 1024x768, 1280x720, and 1920x1080 (HDTV) matrices are some common DMD sizes. These mirrors can be repositioned rapidly to reflect light either through the lens or on to a heat sink.
An organic light-emitting diode (OLED) is a thin-film light-emitting diode(LED) in which the emissive layer is an organic compound OLED technology is intended primarily as picture elements in practical display devices. These devices promise to be much less costly to fabricate than traditional LCD displays. When the emissive electroluminescent layer is polymeric, varying amounts of OLEDs can be deposited in rows and columns on a screen using simple "printing" methods to create a graphical color display, for use as computer displays, portable system screens, and in advertising and information board applications. OLED may also be used in lighting devices. OLEDs are available as distributed sources while the inorganic LEDs are point sources of light.

Observations in Poetry and Pictures:
The Words and Images of Adolfo Caso
By Adolfo Caso*
The Dante University Foundation, Inc.
ISBN : 0937832464
70 Pages, MultiMedia
I do not immediately understand all poetry-yet the words speak to my heart and it responds. So, oftentimes, I read and reread a selection until the words flourish in my understanding. When I opened Adolfo's CD, I found that I went through it three times before I forced myself to stop. And now, as I write this review, I begin again...watching, reading, listening and enjoying!
This work is a delight! This is a magnificent array of sights and words that capture you from the introduction to the end.
My eyes were first drawn to his photography. Immediately it spoke to me as I relished someone else's interest in rock formation and its beauty. I thought of my own rock garden scenes and wanted to share and talk about the visions he had presented to us. I want to go to these places that have been captured; I want to walk near and touch the images--are they really so beautiful? I want to sit and study this beauty, see it from different angles than those that have been captured. . Each picture is intriguing, beautiful, and evocative-there is no choice but to immediately go now to read the words!
Adolfo and I briefly met many years ago in Chicago...then I grew to know him through his book, The Straw Obelisk, But, Adolfo's poetry and photography allowed me to come to know him, yes, as a true artist. His claim that he did not have the talent to become an artist is only partially true, for his talents have been demonstrated through words and camera. Come, let us review his words now:
Run:
Fulfill those Urges
That surge within your soul,
Kiss:
If you don't do it now
You will miss the bliss
That attracts the young.*
*Part of "Why Dream, " p.4.
Here they are; here they are,
The God-made couple
I brought my hand to her breast
And there beheld Paradise.*
*Part of "Evening in Spring," p.10
Whether the words are of love, man's flight into space, Kennedy's death, or the many other issues expressed, they solicit passion, wonder, and tears. We hear the music that he hears. We laugh or we cry with Adolfo; we empathize through his words. And it is good to share his thoughts. For those of you who know the language, the final selections are provided in both Italian and English and as he shares memories of Naples and Milan, it will be a special blessing for many of you.
During my third time through, I noticed a little mark above the directional arrows. Clicking in curiosity, I am amazed to find Adolfo, sitting at a little bistro table, an espresso before him...and he's talking to me! He tells me about why he writes, he shares intimate thoughts as we sit there. Other times, I click and a lovely female voice is reading along with me, articulating each word carefully, so that I may enjoy each word more fully.
I was impressed...no doubt about it! This book in macromedia form is something that will be held close and enjoyed over and over. Adolfo, I applaud your works, I embrace your words to my heart and I delight in the sights you have shared. There is no doubt whatsoever...get this CD!

As time passes, the prices of LCD TVs are going nowhere but down. A few years back, there were only a few name brands such as Sony, LG, Philips, Samsung, etc. But there are several new entrants in the LCD TV market such as Westinghouse, Maxent, Norcent, Syntax, Olevia, etc. These new companies are pricing TVs lower than the established brands, sometimes even by as much as $1000. Naturally this is creating a furor in the market as even big names are being forced to pull their prices down to keep up with the competition.
The question always asked when buying a LCD TV is, why not go for a cheaper brand if it provides the same quality for a $1000 less? The purpose of a LCD TV is to produce high quality images. Newer brands (read cheaper brands) force themselves in the market by lowering their prices, but their quality is rarely up to snuff. They may not be able to compare with the images produced by, say, a Sharp or a Sony. There are many nuances in pictures like contrast ratios, intensities, etc., which cheaper TVs do not provide. However, cheaper sets compensate for their flaws in quality by sleeker designs and other peripheral features. If you are not too keen on image quality, but the price cut matters to you, then you may go for a cheaper TV.
Cheaper brands might also skimp on after-sales services and warranties. There are exceptions, though. Yet, a bigger brand with more experience at after-sales service may be more trustworthy.
The price of an LCD TV depends on the panel, which is the image display. The prices are drastically falling. Thirty to 32 inch panels now cost under $500. Even the prices of the most popular size, 42 inches has come down to $2500, which is significantly less than what it was last year. A complete 42-inch TV from a new brand would cost approximately $3000.
Cheap TVs are constantly being advertised extensively on online portals such as Costco and Best Buy. Sale of cheap TVs online is higher than that of bigger brands, illustrating the fact that people are opting for the technology itself rather than the quality it provides. It is expected that prices of TVs may slump more in successive years. But whatever the case, even the price of the cheapest LCD TV will remain higher than the price of other technology TVs.

Garmin GPSmap 478 GPS Receiver is the best land, road and sea GPS. I purchased it in March 2009 and all I can say is what an amazing GPS unit! I had many GPS devices for the same purposes before but this is certainly the best GPS device I have ever used. It is an excellent portable chart plotter and it absolutely works great in the car, on the sailboat and motorcycle. The mapping software coordinated with the GPS satellites is right on. For Road trips, this Garmin GPSmap 478 GPS Receiver is highly perfect with all of its POIs that is up to date. If you are always inclined to venture off the beaten track or venture off road; then this unit really drops "bread crumbs" so you can easily re-trace your trail all the way back which is always a good thing. I have already recommended Garmin GPSmap 478 GPS Receiver to all of my friends.
I was so surprised on how many addresses and waypoints are built in this amazing device. All markers, buoys and harbors I have needed were all already in the device system. Even both restaurant addresses where I have gone to in Chicago were already found in it.
The big number of page layouts that the device has are so great. It allows you even to customize every single page as well, so this makes it easily for you to monitor many things across a few pages or you can squeeze it all into only one page by choosing a multi-column layout. Now I don't need to even look at my compass anymore as it updates the pages so frequently.
The XM Weather feature which I use both on my boat and motorcycle is absolutely outstanding. It is an advanced device and thus there is no other units such as Nuvi or Zumo can do everything that the 478 unit can do.
The new Garmin 640 is aimed to be a new upgrade for Garmin GPSmap 478 GPS Receiver, however do not be fooled into buying the 640 which is XM only combined with Marine mode, not Automotive mode because 640 is obviously a major downgrade in its functionality than 478. Also, the critically vital Tracks Routing /Saving function which the 478 has has been removed from the 640. Therefore the 478 undoubtedly rocks!
I was originally considering to use other devices of the same kind, but I am so glad that I came across this device because of its comprehensive functionality that I couldn't find in other devices. I purchased my unit from Amazon but before that I checked many websites to compare the prices and Amazon certainly had the best price which I think is the best deal out there you will come across and in just a few days after placing my order they shipped it to me with their super saver free shipping.

Finally, If you are struggling to find a GPS unit that is equally at home, on the road, or on the water and has the best features then I would strongly recommend this unit to you. Check out Garmin GPSmap 478 GPS Receiver to find the cheapest price and get more details. And If you are looking for more info and details on this unit then check out another Garmin GPSmap 478 GPS Receiver review!

Is too much of something a bad thing? Dentists say that too much sugar will rot the teeth. If a person eats a diet high in saturated fat, then they put themselves at risk of having a heart attack. But what about material possessions? Can a television ever be too big?
Flat screen TVs are definitely a material possession, especially when you consider how much they cost versus an older model television, but are they really worth having? It is more than just having a television that has a flat surface. It is about bigger, wider, and thinner and of course, and having a picture quality that is to be envied by all.
The problem in the past was that not all flat screen televisions were better than their round cousins. The flat screen monitor for the computer was very popular and gave a high density resolution. This was applied to big screen televisions.
There is a huge problem with those huge monstrosities. As the screen size was increased, color and resolution became distorted. Therefore, a person would have a giant picture, but the quality wasn't as good as that of small 27" televisions.
When people discuss flat screen TVs in today's technologically advanced world, most are referring to a LCD or plasma television. With a plasma TV, the size of the screen does not matter, as far as the resolution is concerned.
The high concentration of pixels and corresponding programming in the television can offer up an incredibly clear and crisp picture. The 52" has the same picture quality as the 40" and sometimes comes equipped with motion software that makes on-screen movements very fluid.
As with anything being too much, sometimes the prices for these televisions can be more than the average consumer wishes to spend. Flat screen televisions are quite expensive when compared to their cathode-ray cousins. Consumers are going to pay for that technology. A 52" HDTV plasma tv from Samsung runs close to $8,000.00 and that may be more than you want to spend on a boob tube.
Most people still find flat screen TVs a bit expensive and are hesitant to pay so much for a television. You have to remember that ten years ago, the price for a television set was not much more than what is being asked today.
A good quality and size LCD can be purchased at a major retailer for around $700.00. You may even be able to find a sale and purchase one at an even lower price.

What is a Receiver?
A receiver is that big, heavy thing that you plug your speakers and other components into (like a DVD player, TV, CD player, Xbox, PlayStation, iPod, and etc.). Its the "brain" of the show, really. The idea of connecting all your components to a receiver is the concept of audio/video switching, allowing you to switch to different video sources (like TV, DVD, camcorder) on your TV
and thus changing the audio source accordingly - all without touching anything but the receiver.
Of course, the main purpose behind audio/video switching with a receiver is to drive audio to external speakers, like surround sound or stereo speakers.
Most receivers have a plethora of inputs; up to 8 speakers and a subwoofer (more commonly, 5.1, or five speakers and a subwoofer), several video inputs, and even HDMI inputs. You could plug your Xbox, Plasma, and DVD player into the receiver and use one remote to switch between all the different video sources (games, TV, DVD video) and have your speakers pump out surround-sound. Let's start with inputs and outputs. If you don't understand something, read through the entire How-To as most of it will be explained in detail.
Keep in mind that a receiver is the hub of your entire home theatre, so this How-To will actually guide you through the basics of connecting your complete home theater.
So what the heck is all this 'stuff' on the back of your receiver?
I'm going to go over just about anything that you would find on the back of your receiver. The one I'm basing this guide off of is a Harman Kardon AVR-247 I'm going to start from the top left of the unit and work my way to the right, then I'll start at the left of the next row and so on.
The first three inputs are for antennas. An FM antenna cable would slide on to the first jack while two speaker wires would plug into the remaining slots for AM. Of course, you don't have to plug your antennas in, but if you'd like AM/FM reception through your speakers, you'll want to go ahead and do that. These are standard connections, so if you lose one of your antennas, just go buy another for a few bucks.
You've probably heard of composite video. Its a very basic video connection used by most any component (TV, DVD, VCR especially). Its common and its cheap. As such, its very low quality.
Composite uses an RCA cable for video (yellow) and two more RCA cables for audio (red and white, stereo). The problem is that a composite video cable combines luminance and chrominance in the same cable, reducing the quality of the picture. You lose a lot of sharpness, and the color begins to degrade from the original source. Its useful when you need the extra input or the device you're connecting only has composite video. Otherwise, use something else, like component video. Sounds similar; very different.
S-Video is next in line after composite. It uses a different type of connector (five pins in a circle) and gives you marginally better video quality. It is also a video-only cable, so you'll need to plug in audio separately. In this case, you'll probably use a pair of red and white RCA cables for your audio inputs.
Next up: a ton of composite audio inputs. These inputs use left channel and right channel RCA cables, typically red and white. They look just like the yellow composite video cable, and you could even use them for video and the yellow for audio, but let's keep the color scheme how it is ;) Composite audio is the bottom-of-the-barrel in audio. Its perfectly fine for most use, but if you're looking for high quality surround sound, you don't want composite. Game systems, like the Wii or Xbox, and very basic DVD players are a perfect match for composite audio.
The same goes to VCRs, CD players, and anything that only has a composite audio output. Plus, if you don't have surround sound, or your receiver is only two channels (2.1, stereo sound), you won't be able to use anything but composite audio. Note that there is a composite audio input under each composite video input so that it is easy to match them up. Plug them in the wrong inputs and you won't get sound when you're on that particular video input.
Here we have one of the least-used features of a modern receiver: 6 (or 8) channel direct input. This is only used for two purposes: SACD or DVD Audio. SACD is an acronym for Super Audio CD. It is a proprietary audio format developed by Sony for special CDs that are recorded in 5.1 surround sound. That means you need a CD or DVD/CD player that supports SACDs, a receiver with SACD support (as in the picture), and of course Super Audio CD's. DVD Audio is the same idea, different brand, different media (its a DVD, not a CD!).
DVD Audio discs are special DVDs that are recorded in 5.1 surround sound and can only be played by devices with support for them. These CDs go all the way up to 7.1 surround sound, meaning you would need to have two front, two rear, two side speakers and a subwoofer to enjoy full 7.1 surround sound. Most receivers support up to 7.1 now but you won't find DVDs with that kind of capability for movies. 5.1 surround is still the defacto standard, so don't run out and buy more speakers any time soon.
You could skip this next little item because it is unique to this brand of receiver (Harman Kardon). The Bridge" is a proprietary connection they developed for you to connect
an iPod. You need to buy a separate component that includes a docking station and special cables to connect the iPod. It fully integrates with the receiver, displaying
menus and songs on the front LCD screen of the receiver. This allows you to easily pump your tunes through your speakers, whether it be stereo sound or full surround sound.
Of course, the music on your iPod is stereo sound, so the best you can get is simulated surround sound or stereo surround; the same music playing in the front two channels
is put through the rear and center channels. Some receivers do this more intelligently than others, but more on that later.
Here we have our high-end sound inputs/outputs. Basically the same performance wise, you have fiber optic connections (with the square shape) and digital coaxial (just like an RCA cable).
Both of these are 100% digital, whereas composite is analog. The only way you can get true surround sound from any source is by using one of these connections (or the SACD/DVD Audio option)
Almost all DVD players these days have either optical or digital coaxial outputs (sometimes, both). Many high definition cable and satellite boxes also come with these
connections so you can enjoy 5.1 surround sound on high definition channels. Choosing between the two, there's really no different in audio quality, so feel free to use
what you'd like (or what you're forced to).
I don't think I need an image for the next plug. Its a pair of power inputs. One is for powering the receiver, the other for whatever you'd like. This way, when you turn
on the receiver, you give power to the other device (be it a DVD player, CD player, cable box, whatever). I don't necessarily recommend this unless it specifically suits
your needs. It is useful if you're running low on outlets, of course.
Something else you'll never use: D-bus RC-5 input/output. This is used for infrared remote controls to take over your home theater system. Honestly, its not something any of us will ever use. Some of the real high-end junkies might be using something for it, but I've never even come across a device that uses this technology. Stick to the remote that came with your unit, or buy a quality universal remote control. There's no need for this option. An alternate use for this may be a bit more common: if your receiver's front panel is blocked (like inside a cabinet), you could get an infrared transmitter to latch on to the front of it. This transmitter would hook up to another device somewhere in your room that will accept signals from your remote control. The receiving device then transmits the remote's commands to your receiver (via the transmitter you've attached to the front over the regular infrared transmitter).
Pre-outs , located right under the Remote in/out. Pre-outs are used when you'd like to add an amplifier to your system to boost the power (and hence volume/audio quality). Average
users will not use this for anything but the subwoofer preout. You'll want to run a subwoofer cable from your subwoofer to the subwoofer pre-out to provide it with
the right frequencies. This is the proper way to connect your subwoofer to your surround sound system. The other inputs won't be used unless you plan on adding
an amplifier. This is highly unnecessary for home use. You might add an amp if you're trying to fill a room the size of a small house with enough sound, but you're not, right?
Here we finally get to the meat of the system: the speaker inputs! Harman Kardon receivers use bind posts for connecting speakers, as seen in the picture. They
work by being loosened up as your turn them counter-clockwise, then you sneak the speaker wire in underneath the caps and tighten them back up by turning clockwise. This'll
give your speaker wire a nice tug fit that probably won't loosen up on itself over time. Other brands may use other types of connectors, but bind posts are very common.
You might have been able to tell this is a 7.1 channel receiver because of the speaker inputs.
You've got room for 2 front left and right speakers, 2 rear left and right speakers,
a center channel, and two left and right "surround" channels which are placed somewhere in between your front and rear speakers ("side surround", or 7.1). If you have enough
speakers, you can go ahead and plug in those extra 2 side ones, but they won't play any sound at all on a 5.1 DVD. You would need a DVD that supports 7.1
surround sound, and at this time, there just isn't a market for it. CDs will gladly blast stereo surround through all 7 speakers, though, so for some larger rooms, that's an
advantage.
Our final set of connectors for this receiver: component video . The best video you can get next to composite or s-video. You'll notice its a set of three cables (all for video),
usually Red, Green and Blue. Don't think that's what the cable does, though - it separates the video signal by luminance and two separate color channels. In the past, component
did it in fact represent R, G, B (splitting the primary colors in transmit and recombining them at the destination device), but that is not used in current component video
connections. Component video can carry high definition signals, all the way up to 1080p, so it is the most cost effective and readily available high definition input.
Not seen on this receiver are DVI and HDMI, the two all-digital video connections.
HDMI is the newest, fastest, sharpest video and audio connection available today. Its the only cable that can carry audio and video in one - not to mention, in high definition.
HDMI must be supported by the source and the display you're connecting it to to use all of its features. Not all DVD players, cable boxes, or receivers support both
audio and video in HDMI. Its becoming more and more of a standard now to support both. The advantage is clear: less cable clutter, higher quality audio and video. You can get up
to 1080p high definition video and 7.1 surround sound through an HDMI cable. Newer cable and satellite boxes, DVD players, high definition DVD players, and more expensive receivers
support the full capability of HDMI. Its the best you can get as all-digital goes.
The last connection for this article is DVI. DVI is also all digital like HDMI, but it cannot process audio signals. HDMI may provide a technically superior image,
but I don't think anyone could tell the difference. DVI supports high definition video all the way up to 1080p, just like HDMI. Its being used less frequently now,
but if you've bought a new computer or video card for your PC recently, it probably has a DVI (or two) port on it. Most computer monitors use DVI now and video cards
have followed suit. HDMI is edging its way into the PC market, but its dominance is seen in the home theater arena.
Now that you've familiarized yourself with common connections, let's plug it all together.
This part of the receiver How-To is going to guide you through hooking a 5.1 surround sound system(5 speakers and a subwoofer) with a high-definition TV, a high-definition cable or satellite box, a DVD player, and a 5.1 receiver.
Your TV & Components
Where you put your TV is dependent on how large it is, how large your room is, and where you will be sitting. If its 50 inches, don't sit more than 10-15 feet away; but no less, either.
A 60" set is perfect for 12-20 feet. If you have a 32 inch set, try to sit no farther than 8-12 feet away. Your receiver, DVD player, cable box, and other components should obviously be close together, but don't place them physically on top of each other. They all get hot, especially your receiver. If you have no other choice, slide a thin piece of plywood between the components to help dispense the heat.
Lay Out of Speakers
The first step is to lay out your setup. Different rooms call for different locations for your speakers and subwoofer. If your room is a typical rectangle, go ahead and place your two front left and right speakers somewhere flush with the television on that side of the room. Your left speaker goes toward the left corner, right speaker toward the right corner. Don't bother with speaker wire yet (unless your speakers come with speaker wire attached already; in that case, just let them dangle for now). Note that which speaker is left or right is solely dependent on how you connect them to your receiver. Your speakers aren't actually designated "left" or "right".
Depending on how you acquired your speakers, your front speakers could be larger than your rear speakers. That's how you know they're for the front. Otherwise, all your speakers are the same shape and size, and you can use each for any purpose.
One exception: the center channel. Usually, a center channel is much shorter and wider than your other speakers. It should only be used for the center channel. Sometimes, all 5 of your speakers could be the same, usually on a very inexpensive setup. You can use any of these speakers for any purpose.
Your center channel should always go either directly on top or under your television set. However you have to do this, get it done! It's not called the center channel for nothing, you know. Any movie will pump out almost 90% of the voices you hear and a majority of the rest of the sounds through the center channel. It is a vitally important component to your surround sound setup.
Your subwoofer should always be on the floor. If it is impossible to place it on the floor, get it as close to the floor as possible. Placing it behind objections or in closets will diminish its effects. In a perfect setup, the subwoofer would be on the floor close to the TV (perhaps off to the left or right) in your line of sight. Nothing should block the side of the subwoofer that air will come out of (usually covered by a grill protecting the subwoofer speaker itself).
When it comes to finding a good spot for your speakers, you might want to mount them. You can usually buy compatible speaker mounts online or in stores. You can also
use existing shelving, buy some shelving, or place them on tables or other objects. No matter how you do it, try to keep the speakers as close to ear level as possible. A speaker mounted at the ceiling of your room isn't going to give you the optimal aural experience.
The last thing to keep in mind about layout is speaker wire. You'll probably need at least 100ft of speaker wire, but you'll often find yourself using much more if you
try running wire through your ceiling, under carpeting, up through the basement, or around objects to conceal it. Take measurements and buy at least 10% more wire than
you think you need. You'll probably use it!
Cabling
You need to know the different kind of speaker wire available to you before setting up your home theatre. If you bought an HTIB (home theater in a box), it probably came with 100ft of horribly cheap speaker wire. You don't want that! Do yourself a favor: buy some high-quality, 14-guage speaker wire. Anything higher than 14-guage is just to thin and will be susceptible to interence, quality loss, and poor quality over longer distances. Fourteen guage is a good thickness and suitable for most home theatres. Make sure its also not too thick - some speaker wire simply will not fit in to the speaker wire jacks on some receivers.
Some receivers use proprietary speaker inputs. Sony is one example. Many Sony receivers have special connectors for speaker wire and will not accept a standard speaker wire. You'll need to use either the Sony-provided speaker wire, take the ends off of Sony speaker wire and put it on your own, or buy some of these special connectors from Sony directly to place on your speaker wire. My recommendation? Avoid any receivers with non-standard speaker wire posts/jacks/connectors. Look for bind posts or other jacks that allow you to slide in and clamp down on a typical speaker wire.
Once you've got your speaker wire sorted out, you'll have to do some cutting and stripping if you opted to purchase your own. This is way easier than it sounds, so don't worry!
Measure out each length one at a time, cutting the speaker wire with either really great scissors or a sharp blade. Now you need to strip the ends of the wire. Use either a stripping tool or plain old scissors. You can place the scissors on the cable and gently apply some pressure as you twist the scissors around the cable, carefully slicing into the plastic coating. Eventually, it'll get weak enough that you can just slide it off by tugging on it with your fingers. You need at least 1/4" of exposed wire.
Now you can connect your speakers. Note on your speaker wire the difference between the two ends. You'll need to use one as your positive and one as your negative. Sometimes the coating is a different color between the two or there is text on one and not on the other. Keep track of this - whichever side you use for positive on your speaker, use it for positive on your receiver. Crossing the two can cause damage, either immediately or sometime in the future. It might work this way but you don't want it to!
Connecting the speakers is easy enough. Front left to front left on your receiver, center speaker to center on your receiver, etc... Your rear speakers may be referred to as "Surround" or "Rear Surround" instead of just "Rear", but keep in mind, if you have a 7.1 or 8.1 channel receiver, "Surround" may indicate side surround speakers, not rear speakers.
Subwoofers
Your subwoofer is going to be a little more complicated. There are a few different ways to do it and many variations of inputs/ouputs on the back side of subwoofers. I'm going to go with the most standard and efficient method first.
You will need a subwoofer cable for connecting your sub. If you don't have one or don't want to buy one, you can substitute it for a standard red or white RCA cable (or a pair, since they are usually connected; just let the other cable dangle). It will work, but its really not the best way to do it. You'll also need whats called a Y adapter. On the back of your sub, there should be a left/right input (red and white). You plug the Y adapter in to these connections and then your subwoofer cable (or RCA cable) in the other end of the Y (note: if you don't have a Y adapter, just choose the left or right input to plug into).
Now, take the other end of your cable and plug it into your receiver's
subwoofer preout. Hopefully you have a powered sub, meaning it gets plugged into an AC power outlet. All you need to do now is plug that in and your subwoofer is good to.
If you don't have RCA jacks on your subwoofer, or it only has speaker wire jacks (and its most likely not powered), you'll need to connect it the old fashioned way. Your front left and right speakers will plug into your subwoofer's ouput jacks instead of your receiver. You'll then run speaker wire from the left and right inputs on the subwoofer to your left and right speaker outputs on your receiver. This way, the subwoofer is powered by the receiver and will not work as well as a powered sub. You also take some power away from your front speakers with this method. A good idea is to buy a new, powered subwoofer with line in RCA jacks.
Connecting the Dots
You've got the hard stuff out of the way. Now finish it up by connecting your TV, DVD, and cable/satellite box. Always try using the best options first. If your DVD
has HDMI and so does your receiver, use it. If your DVD only has composite, s-video, and component, use component video cable. When it comes to audio, you absolutely need
to use digital coaxial (jacks are usually orange) or fiber optic (usually the jack is recessed into the unit and has a door on it; when the door is open, a red light is visible). If you do not use either of these two, you won't get true surround sound! When all else fails, resort to composite (red and white) audio connectors.
Note: Look closely at the connections on your receiver. Everything is labeled, like the first set of red, green, and blue component video inputs might be labeled "Comp 1". If you're using composite audio cablesfor your sound, you'll need to plug them into the jacks that coordinate with "Comp 1". This might not be clear by looking at the receiver, so refer to your receiver's manual to figure out which video inputs use which audio inputs. Most often, you'll be able to configure them from the receiver's internal menu using the remote control.
On some receivers, all the component video inputs, for example, are linked to a single composite audio input (usually "DVD"), so if you connect more than one of the component inputs, you will be competing for sound when more than one device is active. This is why you'd want to configure the component inputs to use different audio inputs.
Your manual is the only way to figure out how to go about it. Composite video will usually match up to composite audio inputs with naming conventions like Video 1 -> Video 1, Video 2 -> Video 2, etc., but cables like component and DVI may not. You should also configure digital audio inputs to match up with the video inputs you're planning on using. For example, if you're using a digital coaxial input (possibly "Digital 1"), and you use component video, you'll want to match "Digital 1" with "Comp 1". Again, refer to your users manual for how to do this.

LCD TVs are a rage these days; largely because they are compact, convenient and the picture quality is great. But because of the substantial cost of the investment, it is crucial to make an informed decision, is case you are planning to buy one.
The twisted nemantic (TN) is the most commonly used type of liquid display used in a wide range of applications these days, including TVs, monitors and computers. A unique feature of this arrangement is that it reacts in predictable ways with light currents, depending on the voltage of the current supplied. Any LCD setup comprises of tiny particles called 'pixels' that are manipulated to present information of produce images, as and when they are turned on by the passage of light. Since, the pixels allows all wavelengths to pass through, the full light spectrum can be maneuvered to produce the desired color.
The obvious advantages of a LCD screen include shaper, brighter images, wider viewing angle and that it functions well under any light conditions. One issue that you need to be aware of is that the picture produced by an LCD screen depends on its dot-pitch-the term refers to the distance between sub-pixels of the same color adjoining pixel strands. The lesser the distance, the sharper, more realistic and detailed the image.
LCD screens come with in-built tuners and speakers, more often than not. This means that they are largely plug-in and watch devices. For this reason, LCD screens are ideal when space availability is one of the issues at hand.
The average life span of any of these displays is about 60,000 hours, which roughly means that even if you watch TV for 24 hours a day you would still take a out 7 years to wear out your LCD TV. Of course the light-source of your LCD is another matter. The latter is crucial especially for maintaining the 'white-balance' in your image. As the bulb ages the images can develop imbalances like red tints etc. In this regard, it crucial to invest in branded displays.
Even though you might end up paying more, it will be worth the investment. In some cases the warranty of the light source can be shorter than for the display. This in turn means that you will have to buy a whole new display because the coverage on the backlight has expired. In some sets the light is replaceable while in others it is built in the set itself. It is thus important to do an extensive research on the backlighting system of your prospective buys, about how it is structured and warranted.

Over the past decade home entertainment technology has really taken some huge leaps forward. Today, the task of buying a new TV is not just a matter of picking your favourite brand or buying the largest size you can afford. There seem to be more options than ever, and this has certainly led to a lot of confusion among consumers. With that in mind, what exactly are the main differences between the different types of TV, and which is the best?
Plasma TVs are one of the older types of flat screen. They are relatively cheap to produce meaning that prices are generally low for the screen size, which led to plasma becoming a popular choice with consumers who wanted to get the largest screen for their money. These TVs use a gas, which then turns into plasma when an electronic current is passed through it; the plasma then emits the light to create the pictures. This results in a high quality, realistic picture that doesn't suffer from motion blur. It also offers a particularly wide viewing angle.
However, plasma screens do tend to only have a lifespan of about 10-15 years and do use a relatively high amount of energy, which is now frowned upon as many consumers are trying to become more environmentally friendly. Plasma screens are also quite thick, and are very heavy for their size, so they can be awkward to move. The screen is also fairly susceptible to glare, especially in bright rooms.
LCD TVs can trace their roots back to computer monitors and were first introduced at around the same time as plasma TVs. These TVs use the same basic technology as your pocket calculator screen and are backlit with florescent light. They have a much longer lifespan than plasma screens, something in the region of 30+ years, and also use much less power. Traditionally LCD prices were higher than plasma, but as new manufacturing techniques have evolved the prices are now rapidly falling.
While LCD TVs are available in a wide range of sizes, they do offer the worst performance of all the flat screens though, not only do they have the lowest contrast level but they also have a slow refresh rate meaning that motion blur often occurs. The viewing angle is also much narrower than that of plasma TVs, which means that it can be difficult to find a location that offers a good view for everyone, especially in smaller rooms.
LED TVs are actually the next generation of LCD screens, as they are based on a similar technology but use LED backlighting instead of the florescent backlighting found in traditional LCD screens. The new backlighting technology means that they are able to deliver a much more dynamic picture quality, they also use significantly less power than even the most efficient LCD TVs. LED screens can be made to be extremely thin, so they offer consumers the ability to place the TV practically anywhere - indeed it is now commonplace to see TVs fastened to the wall in order to save floor space.
As this is still a relatively new development, LED screens do tend to be more expensive than their LCD counterparts. However as LED TVs become more widespread the cost of production is expected to drop significantly, which will be reflected through dramatically lower prices in-store. Having said that, LED technology is considered to be the most reliable of all the flat screen formats so many people don't mind paying a little bit more.
The world of home entertainment can certainly be a confusing place, especially as new advances in technology seem to come along on an almost monthly basis. Hopefully this article has shed some light on the current generation of flat screen TVs, so at least you can stand a fighting chance the next time you venture into the home entertainment section of the electronics store.
