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.

Consumer Electronic Information: The Basics of the DLP Projector

Consumer Electronic Information: The Basics of the DLP Projector
By Simon Canfield

Projectors have come a long way in the past few decades. The desktop fossils that were once used to show home moviesor classroom filmstrips are a thing of the past. With todays technology, you can now experience a projected movie that emulates a full-blown theater flick, without thetime, effort and hassle of standing in line at the local cinema.

DLP projectors also known as Digital Light Processing projectors have brought the proverbial silver screen to the home front. The fact that some theaters actually use this type of technology for feature movie projection makes this truer than you might imagine. After being digitally converted and placed on an optical disk much in the same way as DVD technology is produced the images are fed intothe projector and sent to the movie screen. The main difference is that DLP projectors offer a high definition experience, as opposed to that of a DVD. The result is a picture that very nearly rivals the quality of a 70mm projection, but without the imperfections.

The color accuracy of the DLP system is outstanding, with an end result that beats LCD technology. Some of the advantages that make a DLP the projector of choice are its low power consumption, compactness, micro-mirror construction (which is responsible for the high level screen resolution), high contrast and brightness. All in all, this is the closest that anyone can come to having a bona fide cinema within the confines of their home.

With every set of pros, youll always find some cons lurking in the shadows. Such is the case with the DLP projector. For those who are particularly sensitive to certain visual effects, the DLP design produces a type of rainbow effect, which could serve as a distraction when looking from one side of the screen to the other during viewing. This will play out as a brief splash of colors, which is simply a result of the type of technology thats used in the production of the DLP. Most people dont even notice this color display, but those who are in tune to that sort of thing may see it as an annoyance.

While this is also true for LCD projectors, consumers mightbe disappointed to know that DLP projectors need to have their light source changed after every 1,000 to 2,000 viewing hours. All in all, though, this is nothing new and, when you consider the higher quality that this type ofsystem offers, it shouldnt be seen as much of an inconvenience at all.

Perhaps the most inhibitive aspect to the acquisition of a home theater system, such as the DLP, is that the cost willtypically fall within the range of $5,000 to $10,000 for the mid-range systems, once you purchase everything that youll need in order to complete the set-up. In addition to that, youll have to consider the cost of the rest of your home theater system, since these figures only factor in the DLP expenses.

For those who can afford to do so, the DLP projector is an excellent investment, despite its few downfalls. While no projection system is perfect, DLP is currently the most popular set-up on the market and provides a powerful theater experience for those who arent inhibited by space or finances.

Computer Projector Rentals: A Guide

Computer Projector Rentals: A Guide
By Marcus Peterson

Any meeting or conference requires a computer to handle inputs like data, graphics, video and audio. Computer as a multimedia application has properties comparable to standalone players for VCD or DVD. With the integration of IT and the Internet into the audio visual industry, computers have become an indispensable item of equipment. They are a common product line in the inventory of a/v rental companies.

To have a meeting with computer aided presentation of data, graphics and video, one needs to have a projector that is compatible with different makes of computers such as IBM and Mac. For instance, an iMAC computer has different requirements than other systems. The accessories that come with computer projectors are audio and video cables, speakers and screen.

The type of screen is decided by the number of members in the audience. If it is a small gathering, a 27 monitor may be used. For large gatherings, a flat screen display or a plasma monitor with 50 monitor may be used. If it is a notebook computer, the laptop must be activated to have the output to the projector. Depending on the number of the people, importance of brightness, contrast and resolution, an LCD projector would be a good fit for the occasion.

The important factors an event manager must consider before choosing the a/v system are the room size, lighting conditions, the inputs that will be displayed, the resolution and clarity of the visual images and screen size. Depending upon the requirements, the rental rate may vary from $300 to $500. Also, the rental companies provide value added services such as complete solutions to manage the event.

Computer projectors are used by corporate houses and universities for business presentations and seminars. They can be booked by phone or online. Most rental companies deliver the systems the previous day. The major manufacturers of computer projector systems are Hitachi, 3M, Compaq and Canon.

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.

Tips on Comparing Prices on Projectors

Tips on Comparing Prices on Projectors
By Jim Gelder

Buying a projector is an investment that you want to be sure you make wisely. So taking the time to do some comparison shopping when it comes to prices is simply a smart thing to do and something you certainly wont regret.

There are several ways you can go about comparing prices on projectors. The first is to visit electronics stores and office supply stores that sell projectors and check out their prices in the stores. This is an especially good method during sales. Its also a great way to get a good deal locally because many stores will offer to beat their competitors best price by a certain percentage, which can save you even more money.

You can also research and compare prices on projectors online. Doing your projector price comparison shopping online makes it possible for you to check out a much larger number of prices on projectors than you can do by going from store to store. This will also make it possible for you to check out the prices on a wider number of brand name projectors and even look into the prices of used projectors. Online auction sites such as eBay are great places to compare prices on used projectors.

Consumer report magazines are also a good resource for comparing prices on various projectors. These reports have the advantage of also rating the projectors, so you can compare quality as well as prices on projectors.

This is an important part of comparing prices on anything, whether its projectors or cars. You want to get the most value for your money, and that means that many times a medium priced item is actually a better value than a higher priced one because it has more features than a stripped down top brand name one has.

Also, even before you start comparing prices on projectors, its a good idea to have a budget in mind for what youre willing to spend for your projector. This will help you focus your price comparison, although you dont want to rule out looking into projectors that may cost more than youve budgeted for because you may run into an unexpected bargain as you do your research.

And if the thought of doing all the research needed to compare prices on projectors sounds like work to you, remember that at least half the fun of making any purchase is in the search! Make a game of it and see just how great a projector you can find for the least amount of money, thanks to your savvy comparison shopping. Then take those savings and splurge on something just for you!

Understanding Native Resolution For Your Home Theater Projector

Understanding Native Resolution For Your Home Theater Projector
By Semore Bernstein

What is Native Resolution for your Home Theater Projector?

To understand what is native resolution, lets start with an understanding of the concept of 'resolution'. Resolution is concerned with the mapping of the information within a picture or image by the dot area.

The smaller the dots, and the more densely packed it is, the greater the resolution, since the mapping of dots as measured in pixels constitutes the data for reproducing the images in video outputs of home theater and other viewing systems. This data processing capability of the projector, as measured in pixels, is what constitutes native resolution.

For high definition home theater projector pictures with good resolution, both the native resolution of the projector should match the resolution of the video signal or video input, failing which, distortion of the images is likely. Native resolution of home theater projectors is measured in two dimension figures with current capabilities ranging from (640480, 800600, 1024768, 16001200) for 4:3 image aspect ratios and the occasional odd resolutions like 12801024.

Thus, if projectors of 1280X 1024 native resolution were to map a video signal of resolution 1024 X 768, there would errors and likely distortion in the image. To effectively combat or otherwise provide for different standards, most home theater video projectors come with capabilities of multiple resolution standards, though it is most likely to be multiples of the lower resolution values.

LCD (Liquid Crystal Display) projectors are devices used for displaying presentations or videos in an enlarged size. They are the modern replacements for slide projectors and overhead projects which were popular earlier.

LCD projectors are available in several variants with differing specifications. Choosing the right projector is as simple as knowing what it will be used for. The two parameters needed to compare an LCD projector are - cost and specifications. Knowing what is needed and how much you will need to use the various features / specifications of an LCD projector are going to be will help one compare the projectors with a better perspective. For this reason, it is important to know the basics of projectors before comparing them.

Aspect Ratio: It refers to the width vs. the height of the projected image. UXGA, VGA, XGA, and SVGA resolution all have a 4:3 aspect ratio.

Brightness: A projector's brightness is measured in lumens. The more light in the room where the projector will be used, the more bright the projector should be.

Contrast Ratio: Is the ratio between the darkest and brightest areas of the projected image. Medium Contrast ratio projectors can be found with a ratio of 500:1 to 1200:1.

Data Signal Ports: These ports on the projector should be compatible with whatever image source they will be paired with.

Keystone Correction: This is the ability to correct the image distortion that is created when a projector is placed at anything other than a 90 degree angle to the screen.

Native resolution: This resolution for a digital projector is the actual number of physical pixels on the projector's image chip.

Projection screens: These screens come in various fabrics and sizes. While it's possible to project the images on a blank wall, the best image quality will be achieved by projecting the images on a good screen.

Video Format Capability: A digital projector's video format capability determines which video format data it can accept. Most projectors will offer all three: PAL, NTSC, and SECAM.

A wide range of desired projectors can be found by giving exact specifications on various website over the internet. Once these basic features of projectors are compared and the best suited LCD projector identified, one can go ahead and compare the prices of the required projector.
