Customer Television Projection Reviews

Good TV,

This is a good lcd televisions. I previously had an Olevia (Syntax) 27″ LCD HDTV, and I have to say that this TV LCD LG is a significant improvement. I recommend this TV!

The Good Features tv projection lcd . The speakers are good (no hiss or low quality digital sound). The speakers are hidden below the TV. So it’s good for confined spaces. They’re not as good as a $500 surround sound system with a sub-woofer, but you get what you pay for.

It has an option to turn off the TV power LED when it is not on, which is helpful if you sleep in the room with the TV. The LED also flashes when it receives a command from the remote control, which is good feedback when you don’t notice something is blocking the remote control signal to the TV, like the edge of a TV stand. When the TV is off, the red LED looks like HAL 9000 from the movie 2001, which I got a kick out of.

I like the swivel stand on the TV, which is good for easier cable setup. It’s Energy Star compliant. It has a great user interface for adding and removing TV channels after you have automatically scanned all the channels (tabbed panels with a preview pane). It can handle HDTV (ATSC) and analog TV (NTSC) signals.

The picture quality is much better than my previous LCD TV. I have no complaints when it’s viewed from a typical viewing angle. The Bad Features. Even though it has great side to side viewing angle, it has a slightly worse than average viewing angle from the bottom. So when mounting this TV up high, you should consider wall mounting it with a downward tilt. Viewing from 45 degrees from below washes out the colors, but this viewing angle isn’t typical for most people.

The reflection from the border on the TV can be distracting in a room with a lot of lights when displaying a show with very low light levels (e.g. a horror movie typically has very low light levels). The border also shows dust a little more easily than a matte finish. It’s a nice and shiny TV though.

Anyone who has been watching TV for a few decades now tends to feel that flat panel television is the best thing to have happened to flat panel television. The market is now flooded with advanced television technology in the form of plasma televisions, LCD televisions, DLP televisions and projection TV.

It’s The Difference:
Flat panel televisions comprise of Plasma, LCD, rear projection, and DLP TV. These terms can appear confusing to someone who is trying to decide on which of these is best. Here is a quick look at what goes behind each of these technologies to bring those fantastically real images to the viewer:

Plasma Television: In the flat panel category, in plasma televisions, a variety of gases like neon argon and xenon emit light and color to the TV screen when they are stimulated by electrical impulses. There is a matrix of miniature phosphor coated gas plasma bubbles, which are powered through electrical impulses that result in the formation of the picture. There are some really wide plasma screens available, exceeding thirty inches, with stunning images with the sharp contrast. Plasma televisions are better than liquid crystal displays because they are faster in terms of response, offer a more wide viewing angle. The picture display quality appears far better.

LCD Television: Also called liquid crystal display TV, these are also flat panel TVs. The technology works when a solution of liquid crystals is sandwiched between two glass panes. This solution carries electrical charges. A florescent bulb emits white light, which the crystals block and reflect, which results in the picture the viewer sees on the screen. LCD TVs are very popular with an ever-increasing market. They last long, are slim and energy efficient.

DLP TV - DLP or Digital Lighting Processing technology has come in recently. These projection TVs use a computer chip equipped with innumerable mirrors, which project and then reflect the picture. The picture quality is superior. Today, many home theater systems and entertainment projectors use this technology.

HDTV or High Definition Television is basically a digital format. A viewer can really enjoy the experience of HDTV when the show is made using high definition technology and broadcast through an HDTV signal via an HDTV TV channel to an HDTV television. There are HD ready TV sets in the market today. These have a screen that can display the HDTV signal. It requires an HDTV receiver/decoder to broadcast the signals.

Rear Projection TVs These are large-screen TVs that are more reasonably priced than the others, giving the viewer a great option that combines size with price. Most of these support the HDTV format. Rear Projection TVs use different technologies to produce their pictures and this can be CRT, DLP or LCD. They can be thin and light and have to be viewed straight on to get the best effect.

The great thing about these TVs is their amazing color clarity and life like visuals, making the viewer feel as if she or he is a part of the scene. Market leaders in this field are Panasonic, Toshiba, Hitachi, Samsung, Philips, etc. There is no such thing as the best TV; what really matters is what features matter most to the viewer and consequently what might be a pro for one viewer might well be a con for the other.

When the time comes to upgrade your television, there are many choices available, including the standard cathode ray tube, projection, LCD or plasma TV. While one of the main considerations in choosing a television remains price, the picture quality and screen size is also important to individual viewers. In many instances, the size of the unit plays a role in making a choice fo those looking for a television that remains closer to the wall, the choice is narrowed down to a LCD or plasma TV.

With technology of both types still relatively new, LCD televisions initially cornered the market for smaller screen units, commanding a large segment of the computer monitor industry. The restriction of size in LCD monitors also held a slight edge over plasma technology until a few years ago when it was able to increase the screen size to about 40-inches. In making the choice between LCD or plasma TV, there are a few other factors to consider.

When large plasma televisions first hit the market, a 50-inch unit could cost as much as a used compact car, but better manufacturing and competition brought the prices down to where buying a LCD or plasma TV did not have to focus entirely on price. Plasma units, however, are still relatively unavailable in smaller sizes, a market the LCD technology still dominates.

Larger Rooms Use A Larger Screen

The viewing room in which the unit will be installed, is another consideration. The larger the room, the larger the television that will be required. As far as setting up chairs around the room, the plasma television has a slight edge on the angle of view, while both enjoy a major advantage over projection televisions. Also consider the lighting in the room when choosing between LCD or plasma TV. An LCD unit generally offers a brighter picture in bright lighting conditions, whereas a plasma television usually has a higher contrast level providing a sharper image.

The technology of an LCD or plasma TV is also different, and the backlighting necessary for LCD’s sometimes does not provide for a true black image while plasma televisions can better show a solid black. The power demand of the LCD or plasma TV is about even, although the brighter the image on a plasma television the more electricity will be used.

If you are thinking about the purchase of an LCD projector there are some important factors that need to be considered. You will need to determine how, where and when you will use it. Will you use it in your home or for a business application? With the growth of Home Theater Systems many consumers are choosing to opt for an LCD projector. LCD projectors are becoming smaller and more portable every day and can be the integral part of any business meeting. LCD projectors and laptop computers, DVDs, Camcorders, and other video sources work well together in many formats.

The cost is one of the most important factors with today’s economy. The LCD projector is not a stand alone device. You will need to buy a dedicated screen for the image display. You will need to get the correct video or computer cables that will be necessary. The projector’s lamp and its brightness is a critical factor in the determination of the correct projector for you. If you will be traveling for business you may want to have back up cables and projector lamps available, just in case. LCD projectors may be getting smaller and more portable but they are still fragile. If you will be traveling for business you should invest in a good LCD projection case.
Many cases are light weight and come with wheels attached for easy mobility.

With all these considerations in mind let’s look inside the projector to see what makes it work and the difference in performance. Some of the technical terms to know a little about when shopping for LCD projectors are: resolution, aspect ratio, brightness, flexibility and contrast. All of these relate to the image quality. If you bring the projector home and find out that it does not meet the standards that you thought it would it may end up being a costly mistake.

The resolution of the projector is important. If you will be using it with your laptop it is best to match the resolution so that the signals will be compatible. A projector’s resolution is the amount of pixels it has to create an image. The pixel is the smallest point in an image. The higher the resolution the more pixels and the sharper more defined the image will appear. The resolution is displayed with two numbers such as – (854×480 low resolution) or (1920×1080 high resolution). The first number represents the number of pixels that are in the horizontal row of the image. The second number represents the number of pixels in a row going vertically. The higher the resolution the more the projector will cost.

The higher the resolution the more superior the image quality will be. If your intentions are to relax at home and watch DVDs you really don’t need a projector with an extremely high resolution. If you will be using it with a laptop for a presentation with a lot of text and graphics a higher resolution projector is recommended.

The brightness of the projected image is determined by the projectors output and lamp specifications and the reflective surface of the screen that the image appears on. Brightness is measured in lumens. The higher the lumens a projector can produce the brighter the image will appear. The light level in the room figures in
the brightness scenario. A room with low ambient light and a bright projector will help decrease the amount of contrast in the image. Room size and the distance from projector to screen will also come into play with the brightness of the projected image.

The contrast of an image is the amount or ratio of bright white to a deep black hue that makes up the image. A high contrast projector is best used for video or DVD formats. They deliver a rich, highly color saturated image with good shadow definition. A higher contrast will give the image depth and dimension. A projector with high contrast is best suited for Home Theater Systems where videos and DVDs can come to life. Using a high contrast projector is a waste if you will be using it for business showing simple text or graphs.

The aspect ratio describes the horizontal vs. vertical rectangular shape of the image on the screen. There are two standard aspect ratio formats. They are 4:3 used for standard TV and 16:9 used for HDTV. This calculated 4 units of width for every 3 units of height. However, you will find that many DVDs and videos come with many different aspect ratio formats and will not always fill in the whole rectangular image. There is no one solution or fix to this problem. First you must decide on what formats you will view the most and go with the knowledge that the downside of the image is marginal.

Other not so technical features that you may want to incorporate into you LCD projector. A zoom lens will be useful when setting up the projector for multiple functions in a variety of room sizes and settings. The lens shift is also useful. For the optimal image the projector should be at a height that is as close to the center of the screen that you are projecting onto. The lens shift will move the projector lens left, right, up and down without having to move the projector. If centering the projector to the screen is not an option. If your projector has it you should use keystone correction.

The projector using keystone correction internally corrects the difference of the angle between the height of the screen and the height of the projector. Moving the projector in some meeting rooms is impossible or must be dealt with prior to the presentation.

There also may come a time when you might want to hook up a second computer or DVD if so you must check out the availability of multiple external ports. Check to see if the projector has a built in speaker or look for ports that will give you the capacity to plug into an external system if need be.

One more factor is weight. LCD projector comes in all shapes and sizes. If your business takes you on the road you will need a projector that is portable and easy to set up and breakdown. There are now projectors that weigh less than 5 pounds. The lamp and the lamp housing are the main hold ups in shrinking the projector much further.

The lamp and its lamp life should be considered before the purchase of any projector. An LCD projector lamp is the most important portion of the projector that you will have to replace at one point or another in the lifespan of the projector. You can find lamps that have a long lifespan of 2000hrs. If you use your projection daily that time will disappear quickly.

Some projectors come with multiple lamp modes. In the standby mode the projector may still be turned on while the lamp is off. This mode is useful if your meeting is in one room and your lunch is in another room. The lifespan of the lamp can be extended using this mode. All you have to do when returning from a break is to switch the lamp into active mode. There are also projectors that have a secondary mode. In the secondary mode the lamp is not projected at % power. This mode can be used in a smaller room or setting where distance and brightness is not the top concern. The third mode should always be used when you are finished using the projector. This is the fan mode. You may laugh but this is an important mode. If you turn the projector off without giving the fan time to cool off the lamp may cool too quickly, resulting with a cracked lamp. Turning the projector on and off to quickly is not good for the lamp or the projector itself. Both of these action are not recommended if you want to have your new projector around for awhile.

If you take some time to do some research before you invest in an LCD projector you will end up with a better product to use and enjoy. I hope that the above material helps you get started on the road to your new projector.

Televisions previous to the Plasma TV explosion used the (CRT) cathode ray tube to give users the ability to watch television. CRT televisions works by shooting out a beam of negative charged particles called electrons into a large glass tube. These negative electrons

For the past 75 years, the vast majority of televisions have been built around the same technology, the cathode ray tube (CRT). In a CRT television, a gun fires a beam of electrons (negatively-charged particles) inside a large glass tube. The electrons illuminate phosphor atoms inside the tube (screen), this allows the TV picture to be produced by illuminating different areas of the phosphor coating, this is what gives you the CRT television.

Now welcome to the new face of television, Plasma TV. Plasma has taken the home theater market by storm because of their amazing picture quality and very thin design. The idea of plasma display panels began in 1964 at the University of Illinois. The first displays were very primitive using only points of light created in the laboratory. As time went on digital processing, and other technology, made vivid plasma displays a reality.

Plasma televisions use a much different type of technology thatn CRT models, they use something called pixels. Using a video signal the pixels on the flat screen light up with a high-energy beam of electrons that are separated into the 3 primary colors, red, green and blue. From the illuminated fluorescent lights pixels you get the full color spectrum that produces a full range of colors that give you the image on the screen. Each pixel on the screen has three fluorescent lights in it, a green, red and a blue fluorescent light. Each fluorescent light in the pixel can produce 16 million colors, giving you amazing colors and overall picture quality that you can’t finder in regular CRT televisions.

Another feature that you can’t find in CRT TVs is the widescreen design found on Plasma televisions. The (16:9) aspect ratio is the same dimensions used in movie theaters. This feature gives Plasma flat screen high definition television models a cinematic feel, that is great for watching feature films, concerts, Monday Night Football or anything else you can imagine.

And unlike conventional television models, there are no scan lines on plasma televisions, so the picture is much sharper. The viewing angle is far superior than CRT, there is 170 degree viewing angle so you can basically watch the TV from any area in the room. As I mentioned before Plasma Tvs are very thin, only 3.3 inches in width. This makes them perfect for hanging on your wall, freeing up space in your home. Just like a picture frame, you can now hang your television on your wall!

So who manufacturers these thin TV displays? You can choose from numerous brand names which I’m sure you are familiar with such as, Sony, Sharp, Hitachi and Samsung to name a few. Plasma isn’t the only technology available if you are a HDTV buff, you should also check out LCD televisions and rear projection TVs.

And if you want to find a cheap plasma TV, check out the discount deals available through internet, particularly Amazon.com and Ebay.com. Those 2 online merchants are trusted and can offer not only new, but used and refurbished models for even bigger savings.
