LCD Projector Reviews

Product reviews are more popular now as manufacturers seek new ways to entice customers to spend their hard-earned money on their products. Many companies use consumer product reviews as advertisements, and little wonder why they do. Manufacturers do not have to pay extra to advertising companies for expensive ad campaigns. However, the credibility of product reviews has been criticized. A review that simply reads "I really loved your product! Keep it up!" and leaves it at that is not what you should expect from a product review. With regard to buying something as expensive as an LCD projector, being informed about your prospective purchase is very important. Here is an article on how to look for an LCD projector based on product reviews.

Technical information

An informative product review should deal with information that is directly linked to the product being reviewed and it should be specific regarding its details and specifications. A typical informative product review on LCD projectors should contain the following information: resolution, brightness, price, and potential usage (sometimes called the "for-whom" section).

Resolution is how clear and tight the graphics being displayed are and they are usually determined by the number of dots per inch (dpi). A higher resolution means tighter graphics and less pixellation (the grainy quality in some images).

Brightness is exactly that--how bright the image being projected is. This determines from how far away the image can be seen. The brighter the image, the farther away it can be seen.

Reviews that include information on potential usage are particularly helpful. This section allows you to find out specifically if the product you want is applicable to your needs. Simply parallel yourself or your company with any one of the list of potential users, and you will be able to tell at a glance if the product is what you are looking for or not.

The reputation of the reviewer

Anybody can write a product review that is why you should be careful when taking advice from product reviews. If the review you are reading comes from a reputable Web site or magazine, then you should be in good hands. Be sure to do some research on the party doing the review before you take advice from them, or you may end up with a very expensive paperweight.

LCD Projector Rentals

There are a few basic rules you need to follow when renting an LCD Projector.

Plan ahead, at least one to two weeks in advance, to make sure the right type of projector is available for rent. The type and power of the LCD Projector should depend on the type of presentation, the size of the audience, viewing angle, viewing distance, room brightness, and location. And remember that more powerful projectors are often larger and heavier so they are not very ideal for mobility.

Double-check to make sure that the projector is fully functional and all the connections such as power supply cord, the VGA cable (if connecting to a standard PC or laptop), or S-video (if connecting to standard video sources like VCRs) are in proper order when renting a LCD Projector.

When dealing with the rental company, inquire if they will be able to deliver the equipment and if they are going to pick it up after use. Make sure they will - in order to avoid accidental damage to the LCD projector (and accessories) when it’s being carried around.

Scheduling multiple presentations in a specific area together can be useful because many rental services feature reduced rates for rentals with longer durations. For example, instead of renting an LCD projector for just two days at the beginning and end of the week, you may save a lot more money by renting it for a for a business week.

LCD projectors are typically more expensive than conventional ones. So, most rental services will allow you to purchase insurance for a small fee, which can be much cheaper than repairing or replacing the projector in case of damage.

Home Theater LCD Projectors

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.

Digital LCD Projectors

Digital projectors are the modern replacements for the rather traditional transparency projectors. Transparency projectors worked by shining light through a semi-transparent material. Digital projectors, by contrast, project a digital image directly from a computer through a lens on to a screen.

LCD (Liquid Crystal Display) digital projectors are much lighter and more portable than their CRT (Cathode Ray Tube) versions, making them widely popular. With the advent of new LCD technologies, digital projectors have been developed which have very clear and crisp fidelity even at large projection sizes. The LCDs used in digital projectors are approximately the size of a small color slide, and in fact the projectors operate very much like a traditional slide projector. The main difference is that the slide is constantly changing.

A Digital LCD projector has its light source contained within its base. It projects light upwards through the transparent image (which sits on a glass "stage") to a lens on the top ("head") of the unit and out onto the projection screen. In other words, the light shines through the image to project it. These projectors work well with printed film transparencies or an LCD panel computer display and provide bright, sharp images.

Slightly higher end Digital LCD Projectors can be used for Cinema/exhibition, Post-production, On-screen advertising, Digital film mastering, Multi-media theatrical productions or other large entertainment venues. Most of the recent Digital LCD projectors can be installed with existing film projectors and also provide an interface for theatre automation equipment.

The future of digital projectors is exciting, with new technologies constantly being developed. As more and more theatres switch to digital projection, consumers cannot help but reap the benefits. As these technologies become more affordable they will inevitably find their way into home systems and allow each of us to experience the joy of a full theatre projection in our own home.

LCD Projector Lamps

One of the few LCD projector parts that can be replaced is the projector lamp. LCD projector lamps vary by model, so selection usually depends on the manufacturing company and types such as Incandescent, Compact Fluorescent, Halogen, and HID such as Metal halide and Low/High Pressure Sodium, 3M Projector, Full Spectrum, and Ballasts, to name a few.

The total lamp life is the expected operating time of the projector lamp, which is expressed in terms of hours. Most LCD projectors use a metal halide source with a lamp life of 750 to 4,000 hours or more. Lamp life is not a very useful measurement, since they gradually grow dimmer without burning out and will continue to function even if they are too dim to be considered usable. So the term “peak lamp life” - the time the lamp will last at eighty to ninety percent of total brightness – is commonly used by manufacturers.

In contrast to metal halide lamps that burn with a very white light, halogen lamps burn with a yellowish light, at a steady rate, and have a consistent brightness throughout lamp life; but they only last approximately seventy hours per bulb. Therefore, they are also less expensive.

LCD projector lamps last the longest when the LCD projector is operated in "economy mode," frequently powered down for cool-down periods, and operated in a clean, fairly dust-free environment. Projectors that are subjected to constant use have the highest probability of lamp failure before the end of the rated hours.

How You Can Increase The Lifespan Of Your Projector Bulb Or Lamp


The replacement of projector bulbs is an all-too-frequent occurrence for anybody that has owned a home theater projector for any length of time. While a two thousand hour lifespan may sound like a lifetime to some people, rest assured it is not long before the projector lamp will need replacing. There are however, some general tips that can help to expand the life of a headlamp for the projection unit.

Do not touch the lamp with bare hands
One of the most frequent problems encountered is people replacing the bulbs with their bare hands. While this is fine for an ordinary light bulb, it is not a good practice for a projector lamp. The lamp in a projection unit burns much hotter than any regular light bulbs. The effects of touching it with bare skin are equally magnified and problematic.

Touching a projector bulb with the bare skin leaves traces of oil on the lamp surface. While this may seem a very minor detail, it is detrimental both to the bulb and the quality of the resulting multimedia display. The oils will get burnt onto the lamp and drastically reduce the lifespan. As the oil is baked into the surface, it actually diffuses the light being projected, reducing the lumens actually being sent to the refractive surfaces. The light will not be enough to project the image that has come to be expected from the home theater projection system. While the problem may not be noticeable at first, over the course of a little time, the quality will degrade to the point of not being viewable.

Turn off the projector power after turning off the lamp
It is highly recommended to turn the power on the projector to the “off” position only after having turned off the lamp and allowing it to cool. This will allow the cooling fans to do the job they were designed to do. While rapid cooling and heating result in repeated contractions and expansions of the bulb filament, it is much better that it be done more quickly with the cooling fans. Likewise, turning the projector on and allowing the cooling fans to run for a moment before turning on the lamp will help as well. This will add hours to bulb life expectancy and allow for longer hours of viewing pleasure on the home theater projection system.

Constant Movements
Constantly bumping or moving the projector, especially while it is hot can be very detrimental to the projector lamp. The filament in the bulb loses almost all tensile strength when it is heated during normal usage. It is much the same as the filament in a camp lantern. The principle is the same; the filament effectively becomes almost the same consistency as ash, making it extremely vulnerable to damage when it is hot. Even after proper cooling, the lamp filament is very sensitive. Care should be taken when moving the projector for whatever reason. While it is always a good idea to be careful with electronic equipment, some aspects of the home projector are actually a bit more sensitive.

It will usually be necessary to move the projector when cleaning the filters. As always, it is a good idea to move it carefully without jerking it around or bumping it any more than needed. Taking an extra moment or two to check the projector mount and make sure it is still securely fastened can also be beneficial and prevent slips and movement which may otherwise be harmful.

With a little care and a little preventative maintenance, the projector lamps will still need to be changed, but not nearly as often.

LCD Projectors for Sale


Do you want to continue to be at the cutting edge of technology with high-end presentation products? Do you want to keep your audience glued to you and the vibrant graphics and clear characters of your presentation? Whether you are presenting to 10 or 10,000 people, there is bound to be an LCD projector that is perfect for you. Here is a simple guide on what to look for when you want to purchase one.

Resolution

The first consideration to look for when shopping for an LCD projector is resolution. Resolution is the number of light dots (called pixels) per square inch of the image produced. The higher the number of the pixels, the clearer and tighter your image will be. Also, if your LCD projector of choice is high in resolution, the image you can broadcast can be expanded to greater degrees. If your lecture or presentation is heavy on graphics and high quality color, or if you need to present to a large crowd, then you will need an LCD projector with high resolution.

Brightness

Since the image your LCD projector will broadcast is projected with a high-powered light bulb, you will also want to consider how bright a projection you will need. Again, the brighter the image you project, the farther away it can be seen. This is an important consideration for people thinking of presenting to large and small groups.

Price and other considerations

These projectors do not come cheap, so price is a major consideration. If your company is small, a desktop projector with resolution the size of your typical computer monitor should suffice. Also, be sure to check on compatibility issues. Is the projector you want compatible with your hardware? If it is not, you may wind up with a very expensive lamp. Finally, ask about user support. Does it come with a warranty? If it does, how long is the coverage? Is there a technical support hotline you can call if you have trouble with your projector? All these things will factor into getting an LCD projector that suits your needs.

Benefits of a High-Quality LCD Projector Lamp for Your LCD



In terms of multimedia presentations, LCD projectors have proven to provide impressive image quality and high resolutions. However, if your projector suddenly fails to work and you need to present a proposal with potential clients, it could cause your business to lose money, or worse, it could cause your job.

The most common problem of projectors is the sudden burn out of LCD projector lamps. Fortunately, these LCD projector lamps can be easily replaced. Although anyone can replace the lamps for your LCD projector, choosing the lamp can be an overwhelming task. You need to ensure that the type of lamp you buy is compatible with your projector.

A high-quality LCD projector lamp should be able to operate for over 4,000 hours. However, the measurements of lamp life are not reliable because the lamp can still work, even if it becomes dimmer. For this reason, you need to check the “peak lamp life” listed in most manufacturers of LCD projector lamps, which provides users with information of the total brightness a particular lamp could provide.

Choosing a high-quality lamp for your LCD projector should be your first concern, instead of price. Compared to the affordable halogen lamps that last about 70 hours, metal halide lamps can work up to 500 hours. Meaning, the more expensive LCD projector lamp you choose, the longer-lasting life it would provide.

How to Choose an LCD Projector Lamp

There are only two types of lamps used in LCD projectors – metal halide and tungsten halogen. In order to choose a quality lamp, you have to understand how each one works.

A metal-halide lamp provides better brightness, but lower consumption of power. Be aware that lamp wattages do not reflect the brightness. Metal-halide LCD projector lamps are more efficient because it could provide your projector with a very white light until the end of its life.

On the other hand, tungsten-halogen lamps produce whiter lights because it runs at a higher temperature than other lamps. Although the white light will become yellow during its lifetime, it provides a longer lamp life because of its low-pressure and high temperature features.

Although metal-halide LCD projector lamps are more expensive, they could provide over 2,000 hours compared to the tungsten-halogen lamps’ 70 hours of operation. Be aware that lamps of your projectors could last longer when you operate them in “economy mode”, which automatically cools down when the projector becomes idle.

LCD Projector Reviews

Product reviews are more popular now as manufacturers seek new ways to entice customers to spend their hard-earned money on their products. Many companies use consumer product reviews as advertisements, and little wonder why they do. Manufacturers do not have to pay extra to advertising companies for expensive ad campaigns. However, the credibility of product reviews has been criticized. A review that simply reads "I really loved your product! Keep it up!" and leaves it at that is not what you should expect from a product review. With regard to buying something as expensive as an LCD projector, being informed about your prospective purchase is very important. Here is an article on how to look for an LCD projector based on product reviews.

Technical information

An informative product review should deal with information that is directly linked to the product being reviewed and it should be specific regarding its details and specifications. A typical informative product review on LCD projectors should contain the following information: resolution, brightness, price, and potential usage (sometimes called the "for-whom" section).

Resolution is how clear and tight the graphics being displayed are and they are usually determined by the number of dots per inch (dpi). A higher resolution means tighter graphics and less pixellation (the grainy quality in some images).

Brightness is exactly that--how bright the image being projected is. This determines from how far away the image can be seen. The brighter the image, the farther away it can be seen.

Reviews that include information on potential usage are particularly helpful. This section allows you to find out specifically if the product you want is applicable to your needs. Simply parallel yourself or your company with any one of the list of potential users, and you will be able to tell at a glance if the product is what you are looking for or not.

The reputation of the reviewer

Anybody can write a product review that is why you should be careful when taking advice from product reviews. If the review you are reading comes from a reputable Web site or magazine, then you should be in good hands. Be sure to do some research on the party doing the review before you take advice from them, or you may end up with a very expensive paperweight.
