Choose the Correct Home Theater Projector

Choose the Correct Home Theater Projector

How to Pick the Correct Projector for Your Home Theater

You're finally making the jump to the holy grail of home theater video displays; the front projection system. There's nothing else that delivers that really big, impressive video image like a front projection system. It's how you get that real cinema experience in your home theater. Home theater projector prices have plummeted in recent years, and the size of the units have shrunk right along with the prices. No more do have to live with a coffin sized box on your ceiling. As sizes have decreased, the image quality and brightness have actually improved dramatically. You'll notice image quality and brightness are two separate issues.

How do choose the correct home theater projector for your application from the myriad of projectors on the market today? There are so many different units, each with their strengths and weaknesses. First of all, there are two main projection technology categories, analog and digital. Analog projectors are based on CRTs, a mature technology that's been around for decades. Those are the projectors with the separate red, green and blue picture tubes and three lenses on the front. The other projectors use one of the newer digital technologies. These projectors have a single lens on the front. There are three major types of digital projectors on the market today; LCD (Liquid Crystal Display), DLP (Digital Light Processing) and LCOS (Liquid Crystal On Silicon). Each type of digital projector has it's advantages too.

You need to evaluate your specific requirements in order to make the proper decision. First of all, look at the room. Is it a dedicated home theater or a multi use room? Do you have complete control of the light? What aesthetic concerns are you dealing with? What is your projector budget? How large of an image do you want? Do you watch primarily DVD movies, TV movies, sports, or other TV programming? What specific source components will you be using with your projector now or in the future? Is picture quality the most important thing, or are other concerns, such as noise, size or brightness more important? Are you installing the projector yourself, or are you hiring a custom installer to do the installation for you? Where must the projector be placed? Can you get the required video and control cables to that location? These questions must be answered to ensure you get the proper projector for your home theater. If you are using a custom installer, they will take into account these factors and specify the appropriate unit for you.

Dramatic improvements in the picture quality of digital projectors notwithstanding, CRT projectors still deliver the most film like image. They have no pixel structure and deliver rich, deep blacks. Properly set up and calibrated, with a good video processor, and with the proper size screen, a CRT projector will deliver simply stunning picture quality. You'll need to use a good quality projection screen, typically with 1.3 2.5 gain depending upon the size, viewing angel and ambient light in the room. Prices on really great CRT projectors have fallen like a rock in the last year or two. You can get a 9 CRT projector that used to cost $35,000 to $50,000, for less than a third of that figure now. Many firms no longer make CRT projectors due to the decreased demand for projectors using this technology. In addition, the required video processors have decreased dramatically as well. Ten years ago a great video processor used to cost $10,000 to $20,000. Now you can get one for well under $5,000 and as little as $2,000, brand new. They also easily last 8,000 10,000 hours when properly set up.

If they are so fantastic, why doesn't everybody still use CRT projectors? Well, there are many detriments to a CRT projector as well. The best ones, with the 9 tubes, are simply huge. It's like hanging an upside down bathtub on your ceiling. If you want to put one under a coffee table, it'll be one large table. They are also very heavy, around 150 200lbs, so you need the proper structure to support them. CRT projectors also require precise placement. They must be perfectly square with the screen, at the correct elevation for good picture quality. In addition, while many digital projectors have zoom lenses, allowing the projector to be placed at a range of distance from the screen, CRT projectors must be at a very precise distance for a specific screen size. These factors severely limit placement options. While the larger CRT projectors put out more light than their smaller counterparts, they have pretty dim images compared to even the least expensive digital projectors. Finally, CRT projectors require specialized setup in order to get a watchable, much less an optimum image. Every 6 months to a year, they must be re-calibrated to ensure you are still getting optimum picture quality.

There are some very good reasons why most people are using digital projectors in their home theaters today. Many are small and light, require minimal setup and calibration (compared to a CRT), are quiet and have a bright, sharp image. But, there are many different digital projectors, ranging in price from around $700.00 to over $100,000.00. Which one is the best for your specific application? Thankfully, the situation is changing, but many of the digital projectors marketed for home theater use are really just re-badged presentation units. Presentation projectors sacrifice good video quality for brightness. Brightness is much more important when giving a Powerpoint presentation in a lit room than the correct color palate or the black level. The red on the pie chart looks great, no matter what, as long as you can see it from the back row.

You want to choose one of the newer units that has been truly designed for home theater applications. The actual technology used for the imaging chip is not all that important, there are great examples using all three of the digital technologies. Companies such as Sony, Runco, InFocus, Vidikron, Marantz, Benq, Panasonic, Sharp, Optima and Sanyo and some others all make great home theater projectors. The projector will have great black levels, to accurately reproduce detail in the darker areas of the picture and give great contrast. Absolute brightness is not extremely important, unless you have a multi-use room without complete light control or you have a lot of people over for sporting events. If you are entertaining many people for sports, it's nice to have some light on in the room, so a brighter projector is advantageous.

Projectors come in a number of different resolutions. The lower the resolution, the smaller the screen you can use before you can see pixel structure. Also, the lower resolutions will not support true HDTV. Most will display HD, but at a decreased resolution. The lowest end projectors typically have resolutions of 800 x 600. The Texas Instruments Matterhorn chip is popular on budget priced wide screen projectors, and has a resolution of 1024 x 576. Anything over a resolution of 720 will allow for true HDTV. The TI series of HD-2 DLP chips has a resolution of 1280 x 720. In April of 2005, TI announced new DLP chips with 1920 x 1080 was ready for production, allowing for true 1080p resolutions. Projectors with this chip will begin shipping in Q1 of 2006. Blu-Ray Disc has stated they will support 1080p, so by late 2006 there will be commercially available 1080p content besides Microsoft's WMHD discs.

Another very important aspect of home theater projectors is the internal video processing. This is one of the primary differences between good home theater projectors and presentation projectors. Digital projectors must display progressive scan images at the native resolution of the chip, so any interlaced signal, such as 1080i HDTV, must be de-interlaced and then scaled to the native chip resolution. Poor quality video processors, weather in the projector or external units, cause all sorts of video artifacts that can get in the way of a satisfying video presentation. This subject alone is too in depth for this article, as entire texts have been written on the subject. However, one common video artifact is jaggies where diagonal lines are jagged instead of straight. Another annoying artifact caused by poor video processing is moire'. This is a pattern seen as alternating light and dark lines that change position as the image moves.

You'll want to be sure your projector supports the HDMI or DVI with HDCP copy protection to allow you to connect a HD-DVD, scaling DVD player or Blu-Ray Disc player. These devices will only allow maximum resolution on a display that has a digital video input with HDCP copy protection. In the future, cable TV and satellite providers may restrict the maximum resolution to their digital outputs too.

When choosing your new home theater projector, make sure it has the video quality, brightness, size, auditory and budget characteristics that you need. Projectors are a large investment, choose carefully and you will be rewarded with years of thrilling video in your home theater.

Home Theater Projector They Aren't Built The Same

Home Theater Projector - They Aren't Built The Same
By Mike Singh

Televisions are changing rapidly all the time, with consumers having a wide assortment of choices for "outside the box" viewing. But once we enter a darkened room, with a wide screen and high quality movie theater, we become part of the cinema atmosphere or "inside the box" once we go to the theater downtown. When it comes to a home theater projector, we need to carefully think and consider our options. A video projector is like a slide or film projector, because they project an image onto a screen. If we are setting up a projector in our basement, for example, we would need to carefully think about things like the ceiling height, the screen level, and the seating positions. While we need to consider all of these elements, we should take the time to work with a skilled professional to help us in selecting the right projector for our specific needs. If we do not really know a lot about this area of entertainment, it would be hard for us to do it on our own, especially if we do not have the necessary information available. We need to do our homework efficiently when it comes to purchasing a projector.

Quality is one of the most fundamentally important aspects of installing a home theater in our home more than anything else. Each element that we put into the home theater entertainment room needs to be part of the "visual aspect of the cinema". It needs to be purchased with the highest level of quality in mind so that it will be able to give you your money's worth in picture and sound quality, completely imitating every visual part of the actual cinema downtown. The project that you select for your home theater should be the best suited for your specific needs, cost the right amount for your theater budget and it should provide you with the overall best quality picture for your money.

A home theater creates one of the best rooms in the home for entertainment or relaxation. It will be welcoming to the family and friends for an atmosphere that is different, a place to completely get away from things. There should not be a good amount of money installing a home theater system only to find that you have selected a poor quality projector for it, so be careful and shop around. Sometimes we can purchase these with the home theater system as a group package. Other times it pays to select the projector based on its specific qualifications for your needs. In any case, a projector is an important element to carefully consider.

What You Should Know About Buying Projector From Ebay Or Online Auction

What You Should Know About Buying Projector From Ebay Or Online Auction
By Clifford Tan

Many people wish to purchase a home projection theater system but still have to work within the constraints of a budget. Can a budget projector be a viable alternative? While a thousand dollars is still a lot of money, it really is not so much to pay for a good home theater projection system. A good home theater will provide years of entertainment from movies, to video and computer games to vacation picture slideshows. How though, can someone find a projector for less than one thousand dollars? How can anybody find a quality projector that also fits the category of a cheap projector? How can they make sure it is going to suit their needs?

One of the most obvious options is through auctions. This is a very difficult way to purchase a projector. The main reason is that all you can do is asking questions of someone who has already proven that they are a motivated seller, proven by the very fact that they have posted the projector on an online auction. Bidding online can be done with some level of confidence though. It is very easy to conceive of getting a very good multimedia projector for less than a thousand dollars in this manner.

Making sure you ask the questions you want answered is the first challenge in finding a home theater projector online. While this may sound easy enough, it really is not when you think about it. For example:

Buyer: Why are you selling your projector?
Seller: Because I am thinking about buying a new projection system. (Thinking, looking, considering all are terms to make the buyer beware)

Why would this simple question and answer dissuade someone from actively bidding on this projector? Take a moment to look at it more closely. The seller obviously wants to sell the projection unit that they currently own. But why do they want to sell it is the relevant question. The answer states that they are looking, considering, thinking about, or otherwise contemplating the purchase of a new system, this is not to say that they are actively in the process of purchasing a new system. This in turn, should lead the prospective purchaser of the online auction projector to ask themselves, and the seller, a series of other questions. Why are they selling the projector without having found a new one they are sure of?

While there are literally thousands of different combinations of this simple question and answer red flag, the key is the same in all of them. If the seller will not give specifics then buyer beware. It is better to lose a bid on a high quality projection theater system than it is to win even with a low bid for a damaged projection unit. The cost of repairs, while relevant in the long term of projector life is important; it should not have to be a factor when purchasing a new projector, no matter where it is bought.

Things to look for that will indicate it may in fact be a quality cheap projector usually are some type of upgrade on the part of the seller. While they may still be very happy with the unit they are selling, somehow or another they have managed to put together the money for a new home theater projector display and setup. Another factor may very well be that they were uninformed when they made the purchase.

One key to making a new projector purchase is making sure the store where it is purchased has a good return policy. Ambient lighting, (while the most common factor, is not the only one) will cause many projector displays that look great in the store display to function less than ideally in the purchasers home. It may well be that the seller did not ask the right questions when they bought the projector and they cannot return it. This happens more than most people want to admit with any number of products, not just with projection units. Asking the correct questions can make it easier to figure out if the projector will be right for your needs or not.

Ask the seller about the picture quality of the projection unit they are selling. If the seller is specific and gives you an answer saying that it is not what they expected, there could be other mitigating factors that will make this ideal for you to get a great deal on a great projection system for well under one thousand dollars.

Find out what kind of projection screen they are using. If the projection screen is not ideally suited to the home theater projector they purchased, that could be a point in favor of the buyer. Sometimes a person will spend a great deal of money on a projector and use the blank space on the wall to project the multimedia displays. If the projector shuts off or flickers. This could be an indication that the projector is fine (For the moment) but has been set up somewhere that is either too dusty for the projection unit filters to keep up or it has been set up somewhere that there is not sufficient airflow and the projection unit is overheating. Find out specific details about where the projector is. Do not be afraid to ask questions. The worst that can happen is that they will refuse your bid and save you money. Not a bad deal really, and certainly better than ending up with a home projector that will not work at all or that needs substantive repairs.

If you know that the projector is functioning well but the picture quality is not what it should be, there could well be another frequently encountered problem. This is known as the keystone effect. Most projection units come with keystone adjustment features. The concept is to allow the optic lenses to be adjusted horizontally and vertically. While this can be a great benefit in some projectors, some home theater systems will become quickly inundated with the keystone effect. To make a long story short, the screen and the projector have pixels. The pixels are little concave shaped areas where light is projected and displayed. The keystone effect occurs when the pixels on the screen are not correctly aligned with the pixels being projected from the projection unit. This will greatly detract from the viewing pleasure and often causes unpleasant sensations such as headaches to the viewer.

If a buyer is willing (And well informed enough) to ask specific questions they should get specific answers. If the seller refuses to be specific or to discuss details, than do not bid. Ever! The well-informed buyer will never end up with a seriously damaged projector, and just may, if they ask the right questions, end up with a high quality home theater projection system for well under a thousand dollars.

3 Types Of Home Theater Projector Screen

3 Types Of Home Theater Projector Screen
By Ricky Lim

Nowadays, the types of home theater projector screen is mind-boggling. The terms used for home theater projection screen is also technical and many people do not actually understand what they are buying.

If you are looking to buy a home theater projector screen, you need to first know the different types of home theater projector screens available on the market. There are 3 types.

1) Fixed Home Theater Projector Screen

These are the most common and the simplest projector screens. They are usually permanently mounted on the wall once the home theater room design and performance is settled. One advantage is you can hide those ugly wires and cables quite easily with this type of installation.

The home theater screen fabric is stretched onto a wooden or aluminum framework and is held into place with fasteners. This creates the smooth and wrinkle free white surface. Its important that the home theater projection screen surface is smooth and tightly held together to prevent any creases over time.

Typically, the home theater speakers are then placed either behind or at the sides of the home theater projector screen. This will provides a better movie watching experience comparable to your local cinemas.

If you decide to place the speakers behind the home theater screen, you might want to consider using a transparent home theater screen fabric. The main advantage is it allows the sound to pass through the transparent fabric maintaining the acoustic sound of the home theater speakers.

2) Tripod Home Theater Projector Screens

These types of screen are portable and suitable for temporary meeting, outdoor movie screening and conducting training. They can be transported easily since they can be folded and slip inside a luggage for easy carrying.

It is cheaper than a standard home theater projector screen and is smaller so it is not suitable for use if you want to watch movies.

3) Wall Mounted Retractable Home Theater Projector Screen

These types are installed on the wall or even to the ceiling. They can allow the projector screen to be retracted when not watching. Its available in both manual and electronic versions and can be quite expensive. Unless your home is short in space or you do not have a dedicated home theater room, it is not necessary to have it.

They are probably other hybrid models of home theater projector screens available but these 3 are the most common and widely used at the moment.

DLP (Digital Laser Projection)

DLP (Digital Laser Projection)
By Jawahn Thompson

Forget the overhead projectors that you used in basic school. Gone always (we hope) are the days of blurry slide shows presented on the chalk panel with a projector that takes two folk to hoist. We are ushering in the age of smaller is best, and pairing it with the finest character that you could request for. Digital laser projection (or DLP) engineering is just one of the astonishing original technologies that are taking the area and presenting something that we never still knew we needed until now.

Technology feeds engineering, meaning that the power to make with smaller and smaller components is allowing us to produce smaller and smaller products for our consumers to take and love with greater appliance than always. The DLP engineering was made potential by a small optical semiconductor. This semiconductor contains over two million infinitesimal mirrors, which are hinge-mounted in an angular array. These mirrors are each less than one-fifth the width of human hair imagine the technology required to construct and to mount such tiny mirrors!

These DLP micro-semiconductors work in tandem with digital signals, light sources and projection lenses to project their displays onto screens of up to seventy-five feet. These sophisticated projection systems work in two phases to create colors and shades for projection, first with grayscale imaging and then with color overlay. The micro mirrors can create up to one thousand and twenty-four different shades of gray just by switching on and off. This grayscale adds shading and depth to the color, which is also projected.

The first step in the creation of an image is the grayscale phase. The mirrors, which are each on their own rotating pivots, can create shades of gray by switching on and off several thousand times every second. The mirrors switching on by aiming the mirror toward the projected light or shift away by facing off from the light. Mirrors that consume much moment on produce a lighter shadow of grey pixel than the lights that consume much moment in the away stance. The outcome of these speedy transitions is an extremely careful picture in grayscale. Color is added when the light-colored light generated by the projector passes through a tone bike of crimson, dark, and greenish. These easy colors, when paired with the grayscale and when coordinated by three semiconductor chips, are able of creating thirty-five trillion distinct colors. Each pixel of tone is created by the speedy flashes of soft, significance that a violet pixel will really be a super-speed flare of dark and crimson, which our eyes view and read as the tone violet. The DLP engineering and the surprisingly hi-tech human eyes make jointly to produce a full-color picture of surprising lucidity.

The DLP projectors can make in several ways, including unmarried chips and a lot of three chips working in tandem. The unmarried microchip structure is used in smaller, much private applications, while the multiple microchip structure works better for professional venues and good areas of projection. An unmarried microchip works in the manner described above to produce images for house theatre systems, televisions, and projectors for consumption within businesses. The human heart works with the projector to construe colors and images in a somewhat smaller scale for private uses and applications. The multiple microchip systems, however, make a less differently. This lot of three chips does not rely on a tone bike, but instead utilizes a prism to refract the light into the greenish, blue, and crimson parts. These projectors are better for utmost picture character and brightness in cases such as film and big locale applications. The images produced can be either moving or yet, and are of an astonishing character.

The three chips do not make the same manner, since one microchip is really dedicated to each of the colors coming out of the prism. The colored light refracted onto each of the chips and reflected by it overlaps to develop the surprisingly high-quality and good lucidity that makes DLP renowned.

The advantages of this structure are simple to know. The colors produced by the DLP structure for cinemas are brighter and clearer, not to cite that the DLP projectors are able of displaying eight times the tone of their conventional movie counterparts. The projectors permit viewers to have more practical tone and richer blacks, still in house theatre systems, than were always potential before.

The modern engineering used in DLP is too smaller than existing engineering, making it simple for designers to produce tiny, more effective projectors and televisions for consumers and businesses. Televisions can have wider and larger without taking upward much place into the room, and projectors can consider as less as two pounds while yet producing rich- and bright-enough projections to make with the lights on.

The digital nature of the projection too protects your medium from degradation over moment. Film might break, pull, or be otherwise corrupted, but digital files do not merely decay over moment. Quality and dependability are significant aspects of DLP engineering, which any consumer will find over moment.

These projection systems are an astonishing mix of design and old engineering. The nature of the systems makes it, hands downward, the better medium for anything from a job display to a computer monitor exhibit, and everything in between. DLP engineering is going the manner of the internet it will shortly be a measure in every individual's living for years to go.

10 Must Know Astral Projection Symptoms Don't Attempt Projection Without These!

10 Must Know Astral Projection Symptoms - Don't Attempt Projection Without These!
By Abhishek Agarwal

Remember the story of a drowning man who lost hope because he couldnt see the land? He stopped swimmingeven though the shore was just a mile away! Unfortunately, he didnt know how close he was!

Most people quit too soon because they dont see immediate results. But if you know what signposts to expect along the way, you will know that you are right on track.

Hmmso you have read scores of Astral Projection techniques, tried some of them and still havent experienced a conscious Projection? Dont quit too soon. You may be closevery close!

Below, I have listed some common pre-Astral Projection sensations. The more knowledgeable and prepared you are about the initial sensations associated with out-of-body exploration, the more success you are likely to achieve.

1. Vibrations
Vibrations are probably the most common of all pre-Projection sensations, and you should be fully prepared for it.

You might feel as if a part, or all of your body begins to vibrate. These vibrations normally start slow and gradually intensify. If you experience this for the first time, you might get startled and feel that your entire body is being electrocuted from head to toe! Although the vibrations can be very intense, they are not physical vibrations because nothing physically vibrates.

Vibrations are a sure-shot indication that you are very close to a successful Astral Projection..

2. Sleep Paralysis / Catalepsy
Sleep Paralysis or Catalepsy is another very common symptom that you might experience during your Astral projection practice.

Sleep Paralysis is a state when you may suddenly find yourself unable to move or speak. Your physical body will feel so completely paralyzed that you simply cannot seem to budge any part of your body at all.

If you don't know what's going on, it can be quite scary. But do not be alarmed when this occurs because this condition is perfectly safe. Astral Paralysis means you are very close to the actual exit.

3. Buzzing And Other Sounds
Most common sounds that you can hear are buzzing; whooshing, rushing, roaring, explosions or bird squawking, a chime being struck, knocking, thumping, voices of people conversing with each other, gunshot, loud bell.

Out of all these, buzzing seems to be a very common pre-Astral Projection symptom and can intensify so much that you feel there are hundred helicopters in your ears!

These sounds are temporary and subside once the separation process is complete.

Recognition of such sounds is an important step because they prove to you that you are on track.

4. Visual Hallucinations
While practicing, you may also see geometric patterns, pulsating colors and lights, specific scenes, visions of paradise or hell or anything imaginable.

5. Rapid Heart Rate
Rapid heartbeat is a very common pre-Projection symptom.

The exact reason for this is unknown. But probably the racing-heart phenomenon is because of the opening up of the heart Chakra. Or maybe it is a side effect of fear or excitement. Either case, you need to remain passive and calm.

6. Breathing Changes
This is an apparent shortness of breath. You need to keep cool and the feeling would soon subside.

7. Movement Sensations
You may experience sensations of dizziness, vertigo, falling or flying up at great speeds, rocking or even swaying. These occur because it is the start of the Astral Projection sequence as the Astral body starts to separate from the physical. A very positive symptom proving that your Astral body has loosened from the physical confines!

8. Weight Changes
Changes in feeling of weight can occur.

You may suddenly feel that your body has become very heavy. Or you may feel very light, as if you are weightless.

9. Proportion Changes
You may also feel that your body is changing in proportion. You might have the sensation that you are growing or shrinking in size.

10. Temperature Changes
This is again a very common phenomenon. Your body temperature might drop and you will feel a cool breeze blowing over you.

Conclusion
People are different. Therefore, the sensations you experience will be based on your personality and individuality. The intensity of some of these sensations will vary from person to person.Each Projection attempt may yield different sensations, in a different sequence.

These were some of the sensations you might come across. There are many more. Just be aware of them so that next time you experience something similar, you know you are on the right track!

Home Theater LCD Projectors

Home Theater LCD Projectors
By Jason Gluckman

The most important aspects of a home LCD projector are its feasibility and efficiency, combined with its usefulness. Compared to the CRT projectors, an LCD chip is amazingly small. An LCD projector is also a viable option in terms of power consumption, which is quite low.

LCD home theater projectors are ideal for business presentations, since they operate successfully in rooms where light is inadequate. An LCD projector is also the most viable and admirable choice for home theater use. One of the key features that make LCD projectors popular is that they are reasonably priced compared to CRT types.

However, the home theater LCD projector is not free from limitations. An LCD projector can frequently display \the screen door effect\. As the screen consists of separate pixels, the pixels can be evident on a big screen, thereby giving the illusion of seeing the image through a \screen door\.

An LCD chip consists of a section of different pixels, and in the event of one pixel burning out it presents an irritating black or white blotch on the projected image. Separate pixels cannot be restored, and if a single pixel burns out or the number is greater, the complete chip has to be changed.

One of the crucial factors that should be given adequate emphasis is the fact that the LCD light source in an LCD projector must be substituted from time to time according to the use of the projector. The ideal time to effect the necessary change should be after every 1,000 to 2,000 hours of use. However, the cost can be quite high, going up to a few hundred dollars. Changing the bulb also has its own advantages, since a fresh lamp refreshes the brightness and contrast, and the user can fit bulbs without much difficulty.
