The new flat screen TVs are far slimmer, twenty to fifty centimeters depth, than the standard fashion cathode ray tube tvs, more than 50cm deep, less bulky and less difficult to position for an optimal viewing spot. The rates vary so much depending on whether or not the mannequin you pick is 1080i or 1080p, normal or 3D, Hi-Def prepared and if you want it to be a component in a residence cinema set-up. Whatever your reason, if you decide on to buy a new flat screen TV then right here are some handy suggestions on how to get the greatest performance from it.

One. Location. Wherever you situate your TV is prime. Fence fitted or on a pedestal, eye degree is key and a crick in the neck is no joke. Soon after all, you pick the finest chairs in the residence when you go to the theatre or cinema so you must also position your seating at home. The best place is straight in front of the display, but off to one aspect is fine if you have a big viewing audience!

Two. Atmosphere. This is wherever lights is key. Guarantee that no illumination reflects on the lcd tv, ruining the picture. Set up your new television on a bright day or with the space’s lights switched on to see every locations exactly where lighting can be a distraction. Don’t forget youngsters really should not observe in depth TV in darkened conditions to keep away from eye fatigue and damage.

3. Wired for Sound. Even if your lcd TV has 5:1 all around speakers, you can nonetheless boost on this seem high quality by hooking up the sound output to an receiver and hooking up to your hi-fi speakers. The experience is so significantly superior when you can hear a pin drop in a drama, in addition to the character’s blood-curdling screams from the most current shock horror.

Four. Environmentally Friendly. Several models have Eco settings, building your new TV more vitality efficient both when working an on standby. The UK Energy Saving Trust has accepted quite a few models for their eco credentials, so they are produced making use of less dangerous components and with less packaging. Most suppliers will also bring back your TV following use free of charge or function a free trade-in when you purchase your flat screenTV.

Five. Verify your aerial. If you perceive that the picture is worse immediately after you’ve switched on automated tuning when you’ve plugged in your new television, just don’t assume that your new lcd tv is flawed. Possibly your antenna just needs tweaking.

There you have it. Substituting your older television with a more recent design can get you greater picture resolution, superior audio features with designed speakers. Additionally, there are more suppliers to get in touch to a video games consule, DVD device, amp and if the television doesn’t have built in Freeview then a Freesat/Virgin/Sky set-top box could be connected up. You can constantly also just transfer your old tv into a gamesroom to be a gaming system monitor if you don’t want to use up a operating product.

CHOOSING LCD

Slim and desirable, LCD screens are the new belles of the TV Ball. But they’re not as perfect as you think…
Liquid Crystal Displays have been around for over 20 years, but have only recently become a reality in the TV market.
The reason for this is that their fundamental operation relies on crystals moving in a viscous liquid and, like wading in treacle, it’s a very slow process. Early generation LCD panels simply could not switch pixels on and off fast enough to cope with a moving video image, and consequently remained in clock displays and PC monitors that were predominantly used for near-static images.
Thankfully, as the technology has developed, the pixel-switching time has dropped dramatically and, in the very best models, causes very little motion blur on moving images. This has opened the floodgates for LCD TVs right up to over 50 inches. However, unlike plasmas, price is no indication of quality.

Hot or not?

LCD contrast ratio is generally poorer than any other TV technology as the backlight can leak through the “switched off” pixels. A potent backlight can lift the brightness figures, but colour is dependent on single block filtering, so the total range of colours and the colour saturation are also mediocre. The deep liquid crystal substrate means the picture integrity fades away as you move off axis, although the latest models claim a viewing angle up to 170 degrees. That said, manufacturer’s specification sheets can read like Tolkien-scale fiction at times, so getting a demonstration of an LCD TV before you buy is essential.
So why is LCD currently the must-have technology? Not only are LCD TVs a super slim flat panel, they are much lighter in weight than plasma models, as the LCD itself is made from plastic rather than glass. Screen resolutions are HD-friendly on larger screen models and each pixel has a much better defined edge definition than the glowing phosphor dots of plasma or CRT – creating a very sharp image. LCD TVs do not suffer screen burn-in from constantly displaying static images, are silent in operation and, from an energy-saving perspective, use little electricity.
But the biggest key to LCD TV’s rise has been falling prices. Each panel is cut out of a single large sheet of fully engineered LCD and each new manufacturing generation creates larger initial sheets. This reduces cost per unit and hence the street price.
LCD TV costs will continue to fall, the picture quality will continue to rise and, as features like digital tuners, memory card readers and wireless connectivity become mainstream, LCD TVs will dominate the 32 inch flat panel market.
As long as you make sure you are buying an HD-ready model and try before you buy, you can’t go wrong.

A LCD TV is a flat panel television that offers a high definition picture through recent advances in liquid crystal display technology. Basically, these televisions are able to display color images through refracting white light in highly specific ways as it is filtered by the liquid crystals. The shades of these colors is then determined by the amount of light that is passing through each spot of color, also known as a pixel. In recent years, the annual sales of LCD televisions has finally begun to be greater than that of the hefty cathode ray tube televisions of old.

While there are certainly a great number of features and specifications to look over with each model of LCD televisions, you may find that you can really narrow down your choices by making a couple of decisions on the key options that every LCD TV buyer needs to make. The most important decision for many consumers is how great of a refresh rate they really need in their LCD TV. A refresh rate is measurement of how many times per second the video image on the display is refreshed, and a higher refresh rate results in a much smoother video. Choosing to cut corners on a lower refresh rate is a choice that some consumers later come to regret.

On the other hand, some users find that they are able to cut back a little bit when it comes to the actual image resolution. Because the image resolution is often so high in general with newer LCD TVs, some viewers find that it is very difficult to spot a meaningful difference between the resolution on one model and another, while others are able to spot the difference immediately. Much like choosing how high a sound quality one needs in a home stereo system, the choice of an ideal image resolution is largely a personal one.

Whether you choose a truly high end LCD television or something less expensive, one of the best things about incorporating an LCD TV into your home is all of the savings in space that a LCD television can provide. Because LCD TVs are wall mountable, you may find that you no longer need to use a large piece of furniture for your home entertainment system, and this can really create a lighter feel and look to your home.

While many consumers make the assumption that bigger is better when it comes to a home television, this is not always the case for LCD TVs. Instead, the ideal size for an LCD television is usually determined by the size of the room that the television will be placed in, as well as most viewers will be seeing the LCD from. When a large LCD TV is placed in a small room, it may be difficult for most people to comfortably view the screen from the ideal angle.

Another option that many top models of LCD televisions now offer is a built in capability for accessing streaming video and audio from certain internet websites. As the streaming content of full length feature films and excellent internet radio continues to become more popular online, television manufacturers have begun teaming up with the top providers of this content to connect to your internet connection and download content to your television directly from your wireless router.

Regardless of whether your television watching consists of relaxing with their favorite hit television shows, keeping up with sports or enjoying full feature films, a LCD TV can be the perfect way to take your home entertainment experience to the next level.

A Near High Definition is new type of television that manufactures have launched to enhance a SD picture so that it is Near to High Definition.

Why do you need a near High Definition Television?

There has never been so much choice of HD programmes and movies. Both Sky and the BBCs and ITVs Freesat provide multiple channels of HD. Alternatives to these are Blu-Ray, HD downloads on the Web, or On Demand services from Virgin Media or Tiscali. It might appear as if there is a lot of choice but it still isnt possible to watch all channels in HD. If you arent prepared to pay a monthly subscription fee then Sky isnt an option and your choice will be narrowed considerably because they have the most choice of channels. Furthermore if you dont want to buy or hire Blu-Ray Discs the choice is even more limited leaving 2 channels of free HD channels on Freesat or a small amount of On Demand programmes or films from Tiscali or Virgin Media. Because of these limitations on available HD programmes the television manufacturers believe that there is a need for Near High Definition television.

Standard Definition Broadcasts

The picture of a PAL television consists of thousands of pixels. On a standard definition television the picture is made up of horizontal lines that are made up of 768 pixels and there are 576 horizontal lines i.e.768 pixels x 576 pixels.

A moving television picture is created by showing a series of 25 still frames every second. Each frame contains a still image with slight changes from frame to frame. Each of these frames is divided into two fields, one of which contains all of the odd lines and the other all of the even lines. The displaying of a moving picture using these fields is known as deinterlacing where the two fields of a single frame are combined to form a full frame. The odd fields and the even fields are alternately painted or scanned on to the TV screen each at a rate of 25 fields a second or 50 fields a second when combined. This is where the term a 50 Hz picture has comes from.

The total number of pixels that a television screen has is known as the resolution. A high resolution or High Definition (HD) picture has more pixels than a Standard Definition picture. HD TVs will generally have a sharper picture, or will be capable of displaying a sharper picture, than a Standard Definition TV.

All UK high definition broadcasts are either at 720 p (1280pixels x 720pixels) or 1080i (1920pixels x 1080pixels). You will need a television of a specification of at least HD Ready which will be able to display a 720P broadcast. There arent any broadcasts of 1080 P ( 1920pixels x 1080pixels ) material in the UK at this moment in time. To take advantage of the full reolution of a 1080P tv set you will have to view either Blu-Ray discs or downloads from the internet.

The quality of the picture of a Full HD 1080P TV compared to an ordinary SD TV is around five times greater than a standard definition and hence the reason for the terrific image quality.

Near High Definition TVs are produce a near High Definition image from a Standard Definition source using a method called upscaling.

An Upscaler transforms an input signals resolution to the resolution of the TVs screen. Therefore if you have an HD Ready TV (1280×720 pixels) or a Full HD 1080P TV (1920×1080 pixels) and you watch Freeview or a DVD that has a resolution of 768×576 pixels the TV has to upscale the picture to fill the different resolution TV screen. If television didnt have a digital upscaler the image wouldnt fill the screen and there would be areas of the screen that would be black and unused due the resolution mismatch of the HD TVs native resolution and the resolution of the source.

HD televisions have a video processing chip that upscales the image so that the incoming picture signal has the same resolution as the native resolution of the screen. This is done by first interlacing the picture which allows the digital algorithms and filters to interpolate the image by adding extra pixels and lines.

How well a television upscales an image will depend on the quality of the incoming signal and the quality of the processing chip. Different televisions have different abilities to upscale a picture. The quality of the upscaled image that is displayed will also depend on the quality of the TV sets electronic components and the screen.

All LCD and Plasma televisions have an upscaler to accommodate the different resolutions of various sources so that they fill the native resolution of the screen. What is different about a Near HD televisions is that they use a much more powerful processor in the upscaler that allows them to do a much better job than other televisions.

No matter how sophisticated the algorithms are that guesstimate how the additional pixels should look an upscaled SD image isnt as good as an actual true 1080P HD picture.

The first and only company to launch Near HD TVs at present in the UK is Toshiba with their Resolution + ZV TVs. These will produce a significantly better picture from a SD source than other standard TVs. This is done by means of a Sony PS3 cell processor upscaler which upscales the picture to 1080p.

The enhanced picture is achieved by the cell processor comparing adjacent image frames which it then combines the pixel detail of to enhance the definition. The picture quality is clearer with sharper and richer pictures. The detail is enhanced which sharpens the edge of images and reduces 3D noise. The colour palette is more natural due to enhancement of the blue and green shades minimizing the loss of clarity that upscaling can often cause. Contrast Enhancement results in dark areas becoming darker whilst at the same time the bright areas maintain their brightness. This results in Standard Definition images being crisp and rich with sharper edges and improved texture but the flat areas are not changed.

Upscaling Near HD DVD Players

Near HD differs to progressive scan which combines two interlaced field images into full frames which are together displayed at the same time giving smoother motion. Also this enhances the vertical resolution and prevents artifacts such as line flicker which is flickering between the lines. Whilst progressive scan uses the 2 fields of a frame to produce a full frame it doesnt create extra lines and pixels in the way that upscalers do.

Toshibas upscaling DVD player is the XDE model which isnt the same as other DVD upscalers that are available because it deinterlaces the picture and then upscales the Standard Definition 576 lines to a 1080p near HD resolution. As with the Resolution + on the Toshiba ZV range of Televisions the picture is enhanced to give more detail, more vivid colours, and improved contrast using the same techniques as detailed above.

Should you buy Near HD TVs and DVD Players?

Obviously an upscaled SD 576 line picture is not as good as a 1080P Full HD picture no matter how much digital processing is done. Nonetheless there is no doubt that a much better upscaler in a television produces a noticeable improvement in the picture quality so that it is closer to 1080P picture. A Near HD TV makes even more sense if you arent willing to pay a monthly charge for HD from Sky, Virgin Medias Cable, Tiscalis Service or Blu-Ray discs. Even if you opt for Freesat there is a limited amount of HD channels available so your choice of programmes is limited. Because HD isnt freely available, especially with out paying for it, a Near HD TV is worth considering that will produce an improved picture with virtually any content including 480i, 576i, 720p as well as DVD, Standard Definition Broadcasts and computer games. With all of these sources the picture will be upscaled to 1080P.

The Near HD TVs offer the ultimate flexibility with the ability to enhance almost any source. As more HD options become available either chargeable or free the TV is capable of receiving and displaying 1080P sources so you wont need to upgrade your TV. Toshiba is the only company that offers Near HD TVs and a DVD Player but others will follow soon.

Purchasing a television or any consumer electronic item is like purchasing a car. You have to be concerned about not only the purchase cost but in addition the ongoing repair costs and its life expectancy.

Unbranded cheap Plasma televisions and unbranded Cheap LCD televisions can be bought for less than the similar specification, same size TVs from well known manufacturers like Pioneer, Panasonic, Hitachi, Philips, LG, Sony, Toshiba, Samsung, Sharp and JVC. The secondary brand cheap televisions may well seem to be good value for money even though they are produced by unknown manufacturers. On first examination the features offered can appear to be comparable to those of the known brands. Some cheap brand televisions are also sometimes aesthetically well styled.

Why are the known brands of TVs more expensive?

It is easy to think that you are paying a premium for the badge on the branded models of TVs, whilst this is to some extent true there are additional differences that justify the additional cost of the branded televisions.

Another explanation for cheap unbranded Television brands being cheaper is that they dont operate from costly offices in the UK backed up with warehouses, and staff. They often ship the products directly from the factory in China, Eastern Europe, etc to the retailers warehouse with no or hardly any staff and premises in the UK. This may appear to be good thing and would help explain the price differential.

The manufacturers of Cheap TVs dont need to invest in their brand reliability, as known brands do. This is for the reason that you dont know which factory manufactured the TV so you will not be able to avoid it in the future if you buy another unbranded TV. So they dont have the same incentive to protect their brand from poor performing unreliable products.

The chances of cheap televisions from unheard of manufacturers going faulty are greater because they dont operate the same stringent levels of quality control that the top brands do. As a result the probability that the unbranded cheap Television will go faulty from new, either directly out of the box, or once, or even more than once in the first year is far greater than for the quality known brands of TVs.

Main brand manufacturers of TVs produce better designed internal circuits with higher quality components to improve the reliability of the TV. Cheaper TVs from unheard of brands dont need to do this. Surveys that have been done by the magazine Which have establish that this is the case and main brands of TVs like Panasonic and Sony consistently out perform the cheap televisions from unfamiliar brands.

Less likely to be repaired

The main brand manufacturers of TVs stock spare parts to speed up repairs this doesnt happen for the unknown cheaper TV brands. Often it is very difficult to obtain replacement parts for the unbranded cheap TVs .

Moreover it is more difficult to repair unknown cheaper brand TVs since they havent got the technical support in the UK that the main brands do. Consequently if an repair engineer struggles to carry out the repair he cant ask the manufacturer for assistance so it will be more likely that the Television cant be repaired. For the duration of the first 12 months this isnt a problem since the retailer that sold you the cheap television will have to repair it or replace it. But after this period it means that it is more likely that you will have toreplace the cheaper unknown brand Television earlier than a main brand Television.

I have seen instances on branded TVs where the product has failed 2 years after being bought, and despite the fact that it came with a 1 year guarantee, the manufacturer has replaced the product or subsidised the cost of the repair to defend their brand image. This doesnt take place on cheap unheard of brands of televisions. On the unfamiliar brand cheaper TV when the warranty has expired if it cant be repaired then it will mean extra expense replacing it.

Superior performance on known brand televisions

An extra reason for the higher selling prices for main brand televisions is that the producers invest in research and development to achieve ways of improving the existing technology to enhance the performance of the Television. This doesnt happen with cheap unbranded televisions which have poorer features and performance. If you read specialist magazines like What Hifi or What Videoyou will see that main brand TVs get much better reviews than the unknown cheap TV brands.

Conclusion

The cheaper brands of TVs arent as reliable and dont have the same specification and performance as recognized brands such as Panasonic, Sony, Toshiba, JVC, Pioneer, Philip, Hitachi, LG etc. For the small premium that main brand televisions sell for over cheaper unheard of and poorly supported cheap Television brands, it isnt worth buying the cheaper ones because you will probably pay more in the long run – Especially if you divide the price difference over the lifetime of the TV. In fact in all probability the cheaper TVs are more expensive once all factors are considered. So purchase a known main brand of television and save money in the long run.

When it comes to flat screen TVs the two technologies LCD and Plasma seem very alike with almost lifelike images and the ability to be hung on the wall. Although LCD tvs and Plasma tvs panels may look very similar in the stores, there are lots of differences between the two technologies.

LCD screens explained

LCD is an abbreviation for Liquid Crystal Display. A LCD tv screen is made up of two clear panels between which is a matrix of colour liquid filled pixels. These pixels respond to a small voltage which makes them change state by twisting or untwisting which allows light to pass through them or to be blocked depending on the state of the pixel. This process of twisting takes very little power. The pixels are either red, green or blue and they are structured in a matrix of millions of pixels to make a picture. The coloured pixels of the panel are illuminated from Behind with a back light to show their colour, and areas of light and dark, depending on how the pixels are twisted. Lcd screens are available in small sizes for watches up to 108 inches for large televisions. Manufacturers such as LG, Samsung, Hitachi, Panasonic, JVC, Pioneer, Sharp, Toshiba, Philips and Sony have a range of lcd televisions available.

How does a Plasma screen display a picture?

A Plasma tv screen comprises of millions of minuscule ‘light bulbs’ which are tiny glass cells filled with inert gases such as xenon and neon. These cells are lit by a current being applied to electrodes in the gas filled cell and its atoms become ‘excited’ to a plasma and emit photons of ultraviolet light. These photons in turn strike a phosphor coating which emits visible light. The colour of the visible light emitted by each cell depends on the three different coloured phosphors – green, blue and red, and can together produce billions of colours when combined. As with the LCD tv screen, the millions of cells combine to form the image on the screen. Currently the only manufacturers of Plasma tvs in the UK are Panasonic, Pioneer, Philips, LG, and Samsung. Plasma tvs are available in sizes from 32 inches to 150 inches.

How does the Picture quality and the performance compare?

Brightness

LCD tv screens are able to produce a brighter picture than a Plasma screen. How noticeable or useable this difference is will depend on the location of the screen and what is being viewed. But in normal viewing conditions both LCD televisions and Plasma televisions are able to produce more than enough picture brightness.

Black Levels and the Contrast Ratio

The difference between the extreme of light and dark tones is known as the contrast ratio. Usually the greater the contrast ratio is the more details can be differentiated. In the past LCD tv screens were known to have lower contrast ratios than plasma tvs due to the pixels not being able to totally block the back light on darkened pixels and light would bleed through and make the image lighter. New methods of reducing this light leakage have been introduced on the latest LCD tv screens so that the contrast ratios are closer to those of a Plasma tv. However Plasma tvs are still better because their pixel cells can be switched off, rather than blocking the back light with LCD tvs, and blacks are blacker. The black levels on a television underpins the overall picture quality. If the blacks aren’t black enough then the whole colour palette or colour saturation is affected so that the colours appear artificial rather than life like. The black level on an LCD tv is more dark grey when compared with the black level on a plasma tv.

Colour Saturation Levels

The colour saturation measures the accuracy of how colours are presented on the screen in the presence of grey shades. A higher grey shade will result in lower colour saturation. The colour saturation of a Plasma tv screen is high because of their black levels, their low grey shades, and their ability to switch off pixels when they aren’t in use, thus preventing colours being diffused by the stray light emissions. Hence the tints and hues are visibly more colourful and more life like.

Colour Gamut level

The colour gamut is the set of possible coulors within a colour spectrum that a screen can display. The top end models of Plasma tv and LCD tv manufacturers are claiming that the colour gamut is near to the full spectrum. On comparable priced LCD tv and Plasma tvs, the Plasma tv again out performs the LCD tv on all but the top end models. The reason for this is that for the same manufacturers the colour gamut isnt as good on the lower models. On plasma tv models the cheaper models don’t have such a difference compared to more expensive models from the same manufacturer.

Screen Resolution

This is the number of pixels that make up the screen. The higher the resolution is, the higher the definition and the sharper picture is. Presently, LCD HDTV’s create the image at’20 pixels x 1080 pixels, full 1080p resolution at a lesser cost than plasma tv panels of the same size. There is no difference in an HD LCD tv or Plasma tv for screen sizes above 37 inches. But plasma tv screens of 37 inches and below are at this time only HD Ready but LCD tv models are available from 32 inches upwards in full HD or 1080P.

Response Time and Refresh Rate

These two attributes in combination establish how fast a moving picture a screen can reproduces without the image blurring. Response time is a measure of how rapidly a screen can vary when an input is received. Historically LCD tv panels had slow response times which was the limiting factor causing motion blur because each pixel has to go from an on state, to an off state, and back to on in order to refresh an image. Improvements in pixel response times on LCD tv screens means that the actual response time isn’t the main cause of motion blur, its mostly caused by the refresh rate, or the frame rate.

All LCD tvs and Plasma tvs have until of late had frame rates of 50 frames per second or 50hz. The more costly LCD tv and Plasma tv models now have 100 Hz to compensate for any motion blur. Since the regular signal is only 50 Hz the additional frames are created with signal processing software which interpolates what the extra middle frames should look like. The result is moving pictures that loose hardly any definition and are more fluid. The best Plasma tv screens still respond better to fast motion than LCD tv but the difference has lessened as the best LCD tvs motion response time has improved and 100hz and 200hz has been introduced.

The Viewing Angle of the screen

This is a measure of how far off axis you can view the picture before it fades. The viewing angle of a Plasma television is between 160 degrees to’0 degrees. On an LCD television the viewing angle is about 100 degrees at which point the picture dulls.

The screen surface of lcd tvs and plasma tvs

A plasma tvs screen is a shinny reflective surface which can suffer from glare depending on the room conditions, whereas LCD tv screens have matt finish that reduces glare.

[b]Screen Burn-in[/b]

For Plasma tvs With prolonged displaying of non-moving images, graphics or text, such as a menu bar, channel logo, or news scroll a permanent ghost image can be permanently burned on the screen with a darkened appearance. SO even if the image on the screen is changed or removed it can’t be removed for the rest of the plasma tvs life and is always seen as a shadow image. Regardless of how long a static image is displayed on an LCD tv they aren’t affected by burn-in. But the problem of burn-in is exaggerated and unlikely under normal viewing.

Image retention

This is often confused with burn-in which appears to be similar but it isn’t permanent. The ‘ghost images’ vanish quickly with image retention when a new bright image appears or after a few seconds. For technical reasons image retention is normal and present on Plasma tvs but hardly ever noticed. This effect can be minimised by having a ‘break-in’ period for the first 100 hours of the plasma tvs life. During this period you should watch programs that fill the whole screen and don’t have any bright static images such as station logos or news scrolls at the bottom of the screen. You should also reduce the brightness and contrast to a middle level. The latest Plasma televisions have circuits built in to them to greatly reduce the chance of either image retention or burn-in.

Power consumption

The backlight on an LCD tv is constantly on so the power consumption is almost constant. By manually adjusting the brightness of the back light up or down the power consumption is either increased or decreased. The twisting and untwisting of the LCD pixels consumes hardly any power.

Because Plasma TVs charge the gas in the individual pixels to a plasma to create the light, and the more light that is required on a scene the more energy is used. So pictures with low brightness in them use less energy, and high brightness more energy i.e. the power consumption varies.

On paper it may appear that the Plasma tvs consume a lot more power than LCD tvs. Plasma tv manufacturers have a tendency to quote the most power usage at full brightness. But the plasma tvs power power consumption varies depending on the signal and the amount dark and bright areas on the screen. Studies have revealed that when watching mainly dark programs and movies the average power power consumption of an equal sized plasma tv is really lower than LCD tv. On the other hand if lots of cartoons and sport are viewed then the LCD tv uses less power. Accordingly on average with varied viewing content there is little difference between LCD tvs and Plasma tvs. Plasma tv manufacturers are shortly going to be launching models that will lessen the power consumption by over half.

[b]Plasma tv Life expectancy[/b]

It is common myth that is quoted that plasma tv screens don’t last very long. However manufacturers such as Panasonic are quoting a life expectancy of 100000 hours which is 11.5 years of continuous use. Therefore any concerns are unsubstantiated

[b]Conclusion – which should you buy?[/b]

Both lcd tvs and plasma tvs are able to offer pros and cons. The lcd tvs have higher brightness and no chance of any screen burn. They are also available in thinner designs and they are lighter. When comparing picture quality the plasma tv have more life like colours, higher contrast and blacks that are blacker than lcd tvs. This is not necessarily the case for all plasma tvs compared to lcd tvs. A budget plasma tv will be out performed by a top of the range LCD tv. On balance when the pros and cons are considered a plasma tv is the obvious choice but spend as much as to can on one.

If you are looking for a new television, LCD TVs are a great place to start. The most popular brands are Sharp, Samsung, LG, JVC, Panasonic, Sony, Toshiba, and Philips, but there are several other quality brands available. They come in many different sizes, from small, 15-inch versions to giant televisions of over 100 inches. No matter what space you are looking to fill, there is an LCD TV out there that will fit your location and budget needs.

In recent years, LCD TVs have become very desirable. LCD is another name for liquid crystal display. There is, however, nothing watery about these televisions. The technology uses the rotation of twisted crystals to create images; and the fluid motion of the crystals is reflected in the name. It makes the name a bit confusing so most people just use the short version – LCD TV.

When buying a new TV, there are some important features to compare. This is a major talking point for the Plasma vs. LCD TV debate and is a good way to measure the quality of different brands and models. The contrast ratio is measured by comparing the blackest black to the whitest white. Plasma dominated this area for the first few years by having the deepest blacks, but recently, LCD TVs have bridged the gap with significant technology improvements. Anything over 10,000:1 can be considered an excellent contrast level. A good LCD TV will have a contrast level around 3000:1, but this will vary widely depending on the brand and model. With a very high contrast rate of 80,000:1, Philips’s 40″, 1080p LCD TV is an example of a fantastic contrast rate.

Response time is another aspect of an LCD that will make a difference in your LCD TV’s picture quality. Some indicators of poor response time are ghosting, streaking, or blurring, so an LCD Television with a great contrast ratio can be hampered by poor response time. Although the industry does not yet regulate the measure of response time, Sharps Aquos line of TVs has been accurately measured at 6 milliseconds. This is definitely something to consider when looking for the right TV for you.

What to look for: Refresh rate is displayed on boxes as 50Hz, 100Hz, 200 Hz, 400Hz, or even 600Hz on the newest models. 200Hz marks a substantial increase from 50Hz, but the highest response rates are recommended mostly for sports or other similar fast action programming.

In addition, an LCD television has a resolution of either 720p (HD ready) or 1080p (Full HD). Especially for computer input, LCD TVs have an advantage as they clearly display images that may appear jagged on Plasma systems. The High Definition experience takes television to a whole new level!

Although Plasma TVs are right for some people, LCD TVs offer flexibility with their wide range of prices and sizes. Despite being only three inches thick, an LCD television is a good long-term investment and offers durability with an average life span of 60,000 viewing hours. Their sleek lines add style to any room.

Buying an LCD Television will bring together family and friends for endless enjoyment whether you enjoy watching movies with the kids or rooting on your favourite sports team in that big game.

Purchasing an unbranded cheap Television will cost you more

Before you buy a TV or other consumer electronics item you ought to bear in mind not only the purchase price of the product but additionally the probability of it going faulty, the features and the performance, and the life expectancy of the product.

Major brand TVs from manufacturers such as Panasonic, Philips, Pioneer, Samsung, Hitachi, LG, JVC, Hitachi and Sharp always retail for more than inferior brands of TVs with unfamiliar brand badges on them. The unbranded cheap televisions from unknown manufacturers look like good value for money when compared to the known brands of televisions. The design and features may make justifying the difference difficult.

Why are the known brands of televisions more expensive?

Evidently when you purchase a known brand of TV you are paying a premium for the brand, which you dont do on the unknown brand cheaper televisions. But is this the only difference?

Another reason for cheap unbranded Television brands being cheaper is that they dont operate from high-priced offices in the UK backed up with warehouses, and staff. They often ship the products straight from the factory in Eastern Europe, China, etc to the retailers warehouse with no or hardly any personnel and premises in the UK. This may appear to be good thing and would help explain the price differential.

The manufacturers of unbranded cheap televisions dont have the same incentive to safeguard their televisions from being unreliable or poor quality. It doesnt matter to them if the televisions are unreliable or if they last for 4 years or 7years. Ultimately you wont be able to find out which factory manufactured the television, so you wont be able to avoid it in the future if you purchase an unreliable TV.

The probability of cheap televisions from unknown manufacturers going faulty are greater since they dont operate the same stringent levels of quality control that the top brands do. So the probability that the unbranded cheap Television will go faulty from new, either straight out of the box, or once, or even more than once in the first year is far greater than for the quality known brands of TVs.

Cheap televisions dont have the same quality of circuit design and internal components as those in the branded TVs and therefore the chance of a cheap Television going faulty is greater. This is evident in reliability surveys that the consumer magazine Which has carried out where brands such as Sony and Panasonic consistently out perform other cheaper non brands.

Less likely to be repaired

The major brand manufacturers of televisions stock spare parts to accelerate repairs this doesnt happen for the unknown cheaper Television brands. Often it is very difficult to obtain replacement parts for the unbranded cheap televisions .

If an repair engineer is struggling to discover the cause of a fault on a main brand TV they can obtain technical assistance from the technical department of the UK subsiduary. In a number of cases if the repair engineer can’t repair the fault then the Television manufacturer will even carry out the repair. The unknown cheaper television brands dont have this sort of back up. Therefore not only is it more likely that the unbranded cheap TV will go faulty but when it does it will be more difficult, if not impossible to get hold of technical assistance. Furthermore it will almost certainly take longer to get the parts. If the problem cant be resolved, due to no technical support, it follows that the unbranded cheap TV is more likely to become unrepairable sooner than the major brand TVs and will need replacing at an earlier time.

It is not unheard of when a branded TV has had very poor service history, for the manufacturer to replace, repair or subsidise the cost of the repair outside of beyond the 1 year warranty as a good will gesture. It is improbable that this would happen for a cheap TVs from an unheard of brand, which means that you would have to buy a replacement one earlier than if you had bought a recognized brand of TV.

Superior performance on well-known brand televisions

Another reason for the difference in the price between unknown brands and known major brands is that the major manufacturers invest in research and development to find ways of advancing current technology to improve the performance compared to unheard of brands. Quite often the technology and specification of cheaper LCD televisions and cheaper Plasma TVs from unknown brands is at least a year or more behind the technology in the equivalent major brand LCD televisions or Plasma televisions. The consequence of this is that the performance of known brands is superior to the cheaper unknown brands. Ultimately magazines such as What Hifi and What Video give the unheard of brands of cheap TVs low ratings compared to the recognized brands of TVs.

Conclusion

The cheaper brands of TVs arent as reliable and dont have the same specification and performance as recognized brands such as Panasonic, Sony, Toshiba, Philip, Hitachi, LG, Pioneer, JVC etc. For the small premium that main brand TVs sell for over cheaper unheard of and poorly supported cheap Television brands, it isnt worth buying the cheaper ones for the reason that you will probably pay more in the long run – Especially if you spread the price difference over the life of the TV. In fact in all probability the cheaper televisions are more costly once all factors are considered. So buy a known main brand of television and save money in the long run.
