LCD Projectors

LCD Projectors

A LCD (Liquid Crystal Display) Projector is the modern version of the slide projector and overhead projector. Unlike CRT (Cathode Ray Tube) projectors, the LCD projector does not function according to the traditional projection-tube system.

The LCD Projector usually contains three separate LCD glass panels - one each for the red, green, and blue components of the video signal. The LCD chip is transparent, and when a powerful light source is passed through it, each individual pixel transforms the light and projects the image or data through a lens onto the screen.

The LCD Projector technological revolution started around the mid-1990s, when manufacturers began to use microdisplays and merge illumination and imaging in one device. Following this development, Compaq introduced one of the first ultra-lightweight data projectors in 2000 - the MP1400 using the DLP (Digital Light Processing) technology from Texas Instruments. Most LCD Projectors today support VGA output at resolutions ranging up to 800x600 and 1024x768. They are also usually capable of projecting standard video from a VCRs, DVDs, and cable boxes; and many of them are specialized for use at home, known as Front-Projection TVs.

The main advantage of the LCD projector is that since the LCD chip is miniature in size, the whole unit is quite compact, which is very practical, especially for mobile professionals. Most LCD projectors are also typically capable of producing 2,000 to 2,500 ANSI lumens brightness with 1024 x 768 VGA resolution, resulting in better image quality. Power consumption is also relatively low. And, in comparison to CRT Projectors (which are still manufactured), LCD versions are quite inexpensive. For example, the Sony VPL-CX1 Superlite LCD Video Projector only costs around $2,000, but is still capable of producing super image quality.

Should We Buy A Demo Projector Over A New Projector

Should We Buy A Demo Projector Over A New Projector
By Clifford Tan

After many years experimenting with and learning about home theaters, it is hard not to interject some personal experience into the subject matter sometimes. When I was a teenager, I was piecing together my first home theater projector. I had a state of the art front projector that took up fully two thirds of my bedroom. Intellivision was a modern marvel with 64bit video game technology. Only one thing was lacking, I was buying a new stereo to complete the home theater experience.

There was no way I could have afforded a brand new stereo, but I did, with some patience and searching, I found some demonstration models that were within my meager budget. I completed my first home theater system when I was about 16. Is the demo model still a viable option though? And will it work for home theater projectors in the same fashion?

A fair discount is often given to the purchaser of a demo model. This is done mostly due to the fact that the demo model has indeed been used to a certain extent. While this may not be an issue for some audio and visual equipment, it is necessary to look at the whole picture before deciding if this is the right way to purchase a home projector.

Obviously you must decide if the projector will fit your personal needs. What kind of media display does it offer? Will it be suitable for mounting in your home? Will the cables be included? Is there still any warranty left on the projection unit? Is the projection screen included with the projector? This last part can be especially important since you can be assured that the screen and the projector are fully compatible if the unit has been displayed in the store.

Once all these questions have been answered, even if they are all answered favorably, it is necessary to look at what may be considered the most important two factors to consider when looking at demo models.

The first question to ask is what is the discounted price? While this is usually around ten percent, frequently an otherwise demanding store may be open to negotiations. The second very important question is to get an idea of how much the projector has been run. By knowing this simple fact, you can ascertain roughly how much bulb life will still be in the headlamp.

While it may seem silly to haggle over a light bulb, projector lamps can be a very expensive replacement part, usually costing between a couple of hundred and five hundred dollars each. Is any discount in the price of the home theater projector going to be outweighed by the purchase of a new bulb in the next few months?

With some careful searching and a little patience, a demo model is an excellent and affordable opportunity for the home theater enthusiast, just be careful and remember not only what to look, but what the relevant questions are when you are shopping this way.

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.

Projector Buying Tips: The Best Projector Shopping Guide

Projector Buying Tips: The Best Projector Shopping Guide
By Robert Thatcher

Technology has always been known to make peoples lives better. In fact, some surveys said that 8 out of 10 people who were interviewed showed significant representation of people who were relieved to have the best technology in their lives.

One of the primary reasons why technology is deemed as lifes enhancers is because it can unleash the limits set upon the rigidity of previous inventions.

This goes to show that with the new trend of technology, people can expect a better life because it provides a hundred and one ways of making the impossible doable.

Take for example the case of projectors. Before, projectors are known to be used in movie theaters and during business presentations or seminars.

But with the continuous technological advancement and development, projectors are now known to be used even at home. This is especially true to those who want to create a home-based theater of their own.

Technically speaking, projectors work in a way that the visual aspects that are limited on the tube of a television are directly converted into a bigger screen. This is where the graphics and images are unleashed on a bigger view and where space is no longer constrained in a tube.

However, not all projectors are created equal. Therefore, projectors may vary from one model to another. So the only way to get the best item is to know how to effectively buy a good one.

Here is a list of some tips that consumers may use when buying projectors.

1. Know the available type

Basically, there are only tow types of video projectors: the LCP, or the liquid crystal projection, and the tubed. Both of them can function well as far as projection is concerned.

Also, these two kinds of projectors are unique on each sense of functionality that may influence the presentation and setting up of the item.

Each has its own advantages and disadvantages as well. So it is best to do some research regarding this matter so you would only get the best kind of projector.

2. Decide on the magnitude and weight of the projector

There are three available categories of projectors. These are the conference room projectors, ultralights, and the fixed installation projectors.

Each category has its own purpose. So it is better to know the main purpose of using the projector so that you will be able to decide on what weight and size should be bought.

3. The price

As mentioned, not all projectors are created equal, that is why, they may be priced according to the level of their functionality and the way they were manufactured.

Generally, projectors re priced between $1,300 and $9,000. Though, 75% of the available projectors in the market today greatly fall under the $3,500 to $20,000 price range.

The main factors that influence the way projectors are priced are brightness and resolution. Hence, the higher the resolution and the brighter the projector can display images, the higher the price.

4. Consider your needs

When buying projectors, it really pays when the buyer knows what he needs before going to the store. This will make the buying process a lot easier and faster, avoiding the perils of motivations made by persistent salespeople.

The bottom line is that the quality of images that people should expect is reflected upon how they buy items like this. Hence, it is important to always have the initiative to research on the things that bring about the main concept of projectors.

Compare LCD Projectors

Compare LCD Projectors
By Ken Marlborough

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.

Some Things Your Projector Dealer Might Not Tell You

Some Things Your Projector Dealer Might Not Tell You
By Clifford Tan

A salesman is a salesman. He does not make a living if he does not sell something. So it may sometimes happen that a salesman or a dealer will not tell the buyer all of the relevant facts about a given product. We have tried to list enough of them here to give you a general idea of what to look for and what to ask.

Bulbs or the Headlamp
This is probably the one thing that gets overlooked more than anything else. The bulbs are an expensive part of the home theater system and need to be checked out carefully before purchasing a projection unit. What is the projected bulb life? How many lumens does it generate? These are specific questions that should generate specific answers that the projector dealer may not otherwise mention.

Contrast Ratios
Contrast ratios are something else that needs to be considered. The projector dealer may or may not know the statistics regarding a specific projector unit, but what about the ambient lighting in the room where the projector will be used. Is the light source constant or is it varied? Properly factoring in the light source in the room where the theater projector will be set up is not something that many dealers or salesmen will volunteer to do for the buyer.

Screen
The screen is also an important part of the whole home theater experience. Which screens work best with which types of projectors is likely something the salesman or dealer is not going to know and will not tell you without prodding. Having the information beforehand can save a lot of time and grief when shopping for a home theater projector.

Mounting
What types of mounts are included with the projector is something they may or may not refer to at the projector dealer, but what else is there to consider with mounts? Is the projection unit prone to overheating when mounted on a shelf mount? Is it compatible and able to be mounted in the proper place for the distances in the room where it will be used? Another factor in regards to the mounting of the multimedia projector is the hazard of creating a keystone effect by mounting the projector incorrectly or off center. What kind of variance do the optic lenses on the projector provide to prevent this? Is there only a vertical adjustment or does it have both horizontal and vertical optic controls? Does it only have the keystone adjustments or does it provide digital adjustment as well? Mounting the multimedia projector properly is a key factor in being able to properly enjoy a high quality picture with the home theater projection unit.

Is this the right projector for me?
Is the projector really compatible for the uses that are needed or is the salesman or dealer just trying to push a product off on the consumer? Knowing which projectors are better for what types of displays is something that the dealer may not even know about. Different home theater projectors have different uses. Some work better with movies, videos and video games, and some work better for still-multimedia presentations. Being knowledgeable about which projector does what can save a lot of hassling with the uninformed salesman or the dealer who just wants to move projectors out of his store.

To be forewarned is to be forearmed. No matter how well prepared the salesman is or how honest the projector dealer is, they have many different products that they have to know a lot about. Even the salesman with the best intentions will not know everything about all of the home theater projectors available. There are many things the projector dealer will not tell you.
