Home Theater Plasma TV VS Projectors

Home Theater - Plasma TV VS Projectors
By Jakob Culver

Many homeowners are struggling with an important, electronic question: What is the ideal display for my home theater? Many people have fought this debate, but I'll try to make clear some important considerations.

The most important detail to consider when deciding between a projector and a large plasma television is ambient light. A room with lots of windows presents a problem for a projector because every little bit of ambient lighting degrades the projected image. The ideal environment for a projector is one where you have total control over the lighting. If your home theater uses a projector, you are limited to using it when you can eliminate other light. A plasma screen can be used anyplace, anytime.

Assuming your home theater has blackout curtains, or exists deep underground; let's examine differences between a plasma television and a projector. One advantage of a projector is that you can get a much larger picture than is available in plasma. Projectors can produce images comparable to an 81-inch screen and larger. This just isn't possible with a plasma screen. However, plasma's have the advantage of not needing any amount of space. A projector must have a long enough corridor to project its image on the wall or screen. To get an 81-inch or greater image, you need a decent distance between the projector and the target. Second, a projector's image is dependent on more than the quality of the projector; you must be projecting onto a specialized surface or you lose detail. A top of the line HD projector with a very high native resolution would be wasted if you were just projecting the image onto a wall. You need an equally high quality screen with features such as a matte finish to eliminate reflection and glare. A plasma display requires no additional equipment.

Overall, a projector has the potential of creating a beautiful image, but it needs too much to work effectively. If you're creating a private movie theater with lighting control and an investment in a screen, mounting equipment, and blackout curtains, then a projector is your piece of equipment. For everyone else, I suggest a plasma television.

Knowing what brightness and contrast ratios are best for your lcd projecting needs is probably going a bit too far, but it will definitely help if you do. Used lcd projectors may be a wonderful investment; just because they have been viewed by someone else does not mean it is in poor condition. Lcd projectors are prone to the screen door effect which means certain images may appear as if being viewed through mesh or fine screen. Choosing the lcd projector that is versatile, reliable, and portable may be a tall order to fill if you don't know alot about projectors. In contrast to some of the other lamps in lcd projectors, halogen lamps burn at a steady rate and have a consistent brightness throughout the lamp life. Knowing what is necessary in your lcd projector and how often those features will be needed can help you decide which one is right for the job.

Lamp life for metal halide bulbs in lcd projectors normally range from 750 to 4,000 hours or more depending on how it is used. A review of the upcoming digital projectors is really exciting due to new technologies constantly being developed for the industry. Lcd projectors are versatile, reliable, and portable; this is why they have become really popular over time; they can be transported anywhere. These projectors deliver a better picture than the lcd television sets that are found in most modern homes. Used lcd projectors purchased on ebay normally have a picture on the bidding page; this might allow you to determine the condition before you make the purchase.

Using a Digital Projector

Using a Digital Projector
By Luke Kent

Many schools have one or several digital projectors available for educators to use. Many people are worried that making slideshows and setting up the equipment will take too much effort andtime. On the contrary, the use of digital projectors saves timeand can take minimal effort.

Most digital projectors take no time to set-up. Have someone show you how to set-up the projector a few times and then try ityourself several times until you are comfortable setting up the projector on your own. Each projector and computer have theirown little quirks so having someone who is familiar with the system will prevent running into trouble in the future.

Creating slide shows for your lessons may take a little effort inthe beginning, however, once these lessons are created they will be saved for you to reuse or to tweak. There are also websites like http://MrKent.Net that provide subject specific slide shows for you to change or use as you please.

The only way to find out if using a digital projector is for youis to give it a try. Create or download a short lesson and present it to your students to compare it to your regular lessonFormat. One thing you will notice right away is that you spend more time interacting with your class and less time writing and erasing items on the board.

How To Choose A Projector

How To Choose A Projector
By Jakob Culver

Good presentations make the foundation of the successful business deals. So while making presentations make sure that you have an easy access to a good projector which suits your requirement as this is going to at as a catalyst for a business deal to happen! The picking of projectors is mainly dependent on the type of work or the kind of business that you have. As for an advertising firm presentations are very frequent so they make doubly sure that they procure a good projector!

The other factor that determines the selection of a projector is the dimension of the room or the conference hall where the presentation is scheduled. As the clarity and readability of the data projected varies from the projector which is designed to function in small room as compared to large room , so presentations for larger areas and for a great number of people should be made through more sophisticated projectors.

Portability of the projector is the another issue, if you usually travel from one place to another for their business presentations then make sure that you invest in a good quality portable projector that is easily transported and provides an easy set up. It is mandatory that it can be set up instantly as who would be carrying a throng of technical people when doing mobile presentations. A projector that easily connects with a personal or portable computer will be ideal to make your presentations simple but sophisticated.

Norms suggest that a portable projector with a minimum brightness capacity of at least 800 lumens is fine to handle the presentations. In contrast to this larger projectors must have a brightness capacity of at least two thousand lumens to make the presentation clear even to those who are seated at the back of the room. A projector must have at least a minimum of 1500 lumens to be able to project effectively in a room where plenty of light comes in as when there are no blinds or curtains

Once you have decided on the type of the projector that you will be using, then make sure that you use projectors in a dark room but if it cannot be avoided, always position the projector at an area where there is less light. It is also important to take note of the resolution of your projector as this signifies the amount of pixels it can display. . Projectors can be easily installed but it is best to consult technical people for setting up the projector especially if they will be mounted to the ceiling. Make sure your projector's efficiency will last long by using alcohol or a special cleaning solution for the projector lens.

So go ahead and make a appropriate selection from a wide variety of projectors that are available in the market and just to tell you that vendor will be one happy person to give a trial presentation, so make sure that you dont miss on that as it will throw more light on the projector features.

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.

Video Projector Rentals

Video Projector Rentals
By Marcus Peterson

A video projector is a device that projects a video or computer image onto a screen. The commonly used inputs are video cassette players, CD and DVD players and PowerPoint presentations from computers. Some computers have CD as well as DVD drives which support these discs. Some projectors dont have VGA connectors, which take inputs from a computer.

A video projector employs one of three technologies: CRT, LCD and DLP. CRT projectors are just like television, i.e. they employ cathode ray tubes. The limitations of CRT video projectors are the heavy size and the requirement of absolute darkness for clarity of the picture. LCD projectors employ a special chip so that the advantage is that the projector is very compact. Besides, it has excellent contrast and brightness. The LCD projector employs individual pixels, which produces high resolution. The limitation of a LCD is it produces a screen door effect. Also the repair of one would result in a dark spot on the screen.

DLP technology employs a Digital Micromirror Device, instead of a chip. DLP projectors are highly suitable for viewing movies and also other multimedia presentations. The advantages of DLP projector include color accuracy and no screen door effect.

LCD and DLP video projectors are the favorites and therefore most of the inventory of the rental companies are the above mentioned ones. The rates of these projectors start at $100 and are dependent upon factors such as the resolution and weight. The rental companies provide support throughout the whole day and night. This includes online or phone booking, shipment, installation, and operation support.

Hotels, resorts, convention centers and conference halls enter into contract with rental companies to provide these services. The rental companies have chains of shops across a particular region or nationwide networks. The directories of these service providers can be obtained online, which directs them to the individual websites.

How to Fix a Broken Slide Projector

How to Fix a Broken Slide Projector
By Jeffrey Saunders

A slide projector is a great way to store, share and show photos, presentations and other information. But what do you do when your slide projector is having problems. How to fix it can be a simple matter of jiggling a few wires, cords or cables, or taking the entire projector apart and taking a peek as to whats inside.

The most common problem with a slide projector that needs fixing is a simple projector jam. A projector jam is when one of the slides is stuck in a position that wont allow the carousel to rotate. Now, this may seem like a minor inconvenience, but it should also be the first area you look into when your projector is having problems. How to fix it, and remove the jammed slide can be done in a matter of steps.

1. Shut the slide projector off and let it cool down for a few minutes.

2. Remove the slide tray by loosening a latch or placing a coin in the middle of the tray & turning it

3. Turn the tray upside down

4. Locate the jammed slide and carefully remove it

5. Place the tray back into the projector

6. If the slide isnt damaged, insert it back into the carousel

The next time you notice your slide projector is having problems, how to fix it is to follow the steps listed above. Normally, when a slide projector wont fully rotate, its because of a jammed or lodged slide within the carousel. Carefully removing the trapped slide should solve any projector problems youre experiencing.

If youve followed the steps noted above, and you find that still your slide projector is having problems, an experienced technician may tell you how to fix it, and guide you through various stages of repair. The larger the slide projector you have, the more chances it has to jam. So before you take your projector apart or visit a potentially expensive repairman, be absolutely certain that it isnt a jammed slide thats causing your projector problems.

If your digital image projector is having problems, how to fix it can be a matter of replacing a burnt out bulb, ensuring that all your cables are properly connected to rebooting the entire system itself, depending on the sophistication level of your projector. Always go through the instruction manual when your digital projector is acting up.

Sometimes when your projector is having problems, how to fix it can be as easy as remounting it or reinstalling it. An improperly mounted projector can sometimes not project any image at all, and may appear to be broken and in need of fixing. Check to see if your projector is mounted and affixed straight. If it isnt, take it down and remount it, being careful to make certain that its properly mounted. That should solve any issues regarding your projectors refusal to show images. If that does not work, then you may consider taking your digital projector back to its point of purchase for a qualified inspection.

Jeffrey Saunders loves do-it-yourself technology

He also likes great deals on refurbished electronics. Amazing prices on big brand names like the Apple iPod Nano

And more fantastic deals on great items like digital camcorders.

Video Projector Guide

Video Projector Guide
By Riad Haddad

Well; the world of Projection is certainly a vast place to wonder uninformed, so get informed. I will try to keep this guide as simple as possible.

Things to look for when buying a projector:Manufacturer/MakeThere are many projector manufacturers these days that make it seem impossible to choose from. But to make it simpler, many manufacturers now a days use parts that are supplied from other manufacturer. In other word not all the parts in a projector is manufactured by the same manufacturer. Thus many projectors already have similar components incorporated into them. Always read reviews posted on computer magazines and online computer magazines before purchasing high end/high priced projector. Look for a company that offers the best warranty & support. Brands like Sony, Panasonic, Toshiba, Sharp, In-focus, View sonic, Mitsubishi, Epson are amongst the best there is.

TechnologyThere are many technologies available today. But the main two types are LCD & DLP. In simple DLP which stands for Digital Light Processing uses hair width tiny mirrors to reflect light into a screen. DLP offer better overall image but cost a lot more. So for home users its better to opt for LCD based projector because of there much lower price and higher availability. Also LCD projector offer excellent image that is comparable to DLP. Big companies and presentation oriented businesses well find DLP a better choice. There are also projections panels. Projections panels are a form of transparent display that are placed over an ordinary Overhead projector and used to project the same type of video sources that normal projector use. Projection panels are cheaper than the types described earlier.CRT Projectors are an old projection technology that is no longer used these days.

ResolutionResolution is very important aspect to consider when purchasing a projector. Many older models are VGA (640*480) & SVGA (800*600); these models are good for displaying movies and other low resolution images, but will no be sufficient for projecting high quality images demanded by high end application such as 3d modeling, games, simulators and CAD. Check the simple chart below:

640*480 (VGA) resolutions are good for Video Games, VHS, VCD and Standalone DVD users. This panel is perfect for DIYers wanting to keep costs at lowest.800*600 (SVGA) resolutions are perfect for Computer based DVD playback and normal Windows and operation system work. (Plus all the above)1024*768 (XGA) resolution is perfect for high resolution Computer Games and design applications such as AutoCAD (plus all the above)1280*1024 (SXGA) resolution is perfect for HDTV applications and computer software that require high detail (plus all the above)

Color DepthColor depth states how good the LCD represents color. Its the number of colors a monitor or an LCD panel is able to show. A good color depth is 16-Bit; although 24-Bit is strongly advised, this is the color depth that most high end projection panels have.

Lamps An important thing to investigate is the type of lamp used. Check the replacement price of lamps and life expectancy. It would make you no good if you purchase a low price projector and later find out that every lamp replacement will cost you 400$. New lamp models can work for a minimum of 10,000 hrs.

BrightnessBrightness output is expressed in lumens. The higher the lumens the better the image is displayed in less than perfect lighting conditions. Some new projector models can display a vivid image even with the light on. 2000 lumens is a good choice for home use. Choose 3000-4000 for presentation theaters and jobs that require a bright image in a not too darkened room. Lumens rating of below 2000 such as the low priced 1300 models will have to be operated in a completely darkened room (Pitch Black).

ConnectionsConnections are a very important factor when choosing a projector. Composite, S-Video and RGB is almost standard on most models. You will need RGB for hooking your computer or laptop; Composite & S-Video for connecting DVD players and VCRs. Some newer models have DVI inputs too that enable them to be connected to high quality video systems like a video editor or digital video cameras. A remote control is a must; you don't wan to get out of your comfy chair every five minutes. Some applications require two RGB connections for simultaneous viewing of different video sources, so make sure to check for it if you need it.

Long throw/Short throw projectionIts important to decide where you are going to place the projector. If the projector is going to be placed in front of an audience then you will need a short throw projector. And if you need to fix the projector some where behind the audience (Far from screen) you will need a long throw projector. What happens when you use short throw projector for a behind the audience application is that the image will be too large to fit on screen, and if you use a long throw projector for short distances you will get a very small and unclear image.

DIY ProjectorsWell this is interesting. Did you know that you can build a projector yourself, its not that hard really and it will cost you a fraction of retail prices? You should have basic knowledge with DIY projects. The image quality is very good you won't believe it. Though some patience is required in order to complete the projector.

Film Projector Rentals

Film Projector Rentals
By Marcus Peterson

A film projector projects reels of film onto a screen to form a continuous image. Film projectors have the need to wind and unwind the reels and adjust the arms and distance. Despite the competition from video projection, film projectors have a niche market of buyers.

Film projector rental demand comes from residences, film festivals and university and school campuses.

Film projectors come with different widths such as 8mm, 16mm and 35mm. The type of projector depends on the space available and the number of audience. The demand for 35mm comes mostly from festivals while 8mm and 16mm find demand from other segments such as residences and student shows in universities.

Many of the rental companies are either owned by the universities or reside in the campuses. The demand for film projectors is cyclical as film festivals happen during a particular period of a year. Even for residences, the demand is usually in the summer months, when families like to have get-togethers outdoors.

The rental rates for projectors depend upon the type of films. 16mm projectors have a starting rental rate of $20 per day, 35mm at $50 per day. The total rental rates go up when we consider the screens and other accessories. Most of the a/v industry rental companies hold fewer stocks of film projectors. The rental companies in the university campuses charge lower fees for student groups.

Film projectors face severe competition from video projectors. New technologies such as DLP and audio/video storage media slowly make the conventional film based technologies obsolete. When compared with video projectors, film projectors lack features to control contrast and brightness. Even with cinema halls transitioning to digital forms of projection, film based projector manufacturers are dwindling and therefore are the rental industry of film based projectors.

Digital Projector Give a Bigger Picture

Digital Projector -- Give a Bigger Picture
By NamSing Then

Digital projectors are those video projectors which are used in conferences for presentations. The digital projectors receive video signals from, usually, desktop computers and display images on large screens which can be easily comprehended by all in the gathering.

Two Types of Digital ProjectorsTo begin with, there are two technologies used by digital projectors, the older one being the LCD, liquid crystal display with independent transparent panels of LCD for each constituent primary color (red, blue and green.) The image transmission depends on the signal received by the projector from PC which redirects the light signals through these LCD panels and lens onto a screen. The LCD projectors look pretty similar to older slide projectors and are simple in construction and thus cost less in comparison to their successors DLP projectors. The LCD can be thought of as slides placed at the focal length of the lens making it complete. Clarity of picture in LCD projectors depends on the number of pixels it is set for. (Pixels are smallest area of data or picture holders)

DLP Projectors: The Latest of the Digital ProjectorsDigital Light Processing or DLP is a technology developed by Texas Instruments in 1987. DLP projectors bring in a paradigm difference in technology in image projection to board rooms. Unlike their predecessors, DLP projectors make use of tiny mirrors or micro mirrors to reflect light images to pass through the projector lens and onto a screen. Each mirror can be thought of as representing a pixel. The mirrors reflect primary colors in rapidly rotating succession as actuated by a rotating color filter wheel. The image of rapidly changing colors constructs images for human eye perception. The micro mirrors are collectively called as DMD or digital micromirror device.

For the sake of enhancing picture clarity, the rotating wheel is provided with a plain patch which allows plain white light. This type of DMD projectors are also known as single chip projectors. The three chip projectors are a bit complicated but offer better clarity. Here a prism splits the light from lamp into primary colors which are redirected to DMD which recombines them before projecting through the lens.

Where Is the DifferenceDLP projectors are lighter and give far better pictures. Single chip resolves 16.7 colors while the three chip model does a, hold your breath, 35 trillion colors.

Commercial ModelsTexas Instruments is the pioneer who owns the patent for DLP technology. Fraunhofer Institute of Dresden of Germany developed the same technology simultaneously and markets it as Spatial Light Modulators. HP, Samsung are other market leaders in both LCD and DLP technologies.

LCD Projector Reviews

LCD Projector Reviews
By Ken Marlborough

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.

Light Weight anything over 6 lb is not really portable;

Small Form Factor smaller dimension projectors are easier to pack and carry;

Set-up Speed look for a projector with some quick application select modes which match the type of presentation material and projection scenarios which are likely;

Screen Distance Flexibility flexibility to cope with varying distances from the screen short throw and zoom lenses provide flexibility;

Horizontal and Vertical Lens Shift or Keystone Correction to correct keystoning of the projected image when the projection screen is either not at the same height as the projector and/or horizontally in line / skewed - lens shift is preferred as there is no possibility of introducing artifacts from digital keystone correction;

Good Brightness look for over 1,800 ANSI lumens to cope with less than perfect projection situations with plenty of ambient light (eg. training rooms), 1,200 ANSI 1,800 ANSI lumens projectors can handle some ambient light;

High Contrast Ratio something of the order of 2,000 or over will produce excellent results

Low Noise Level - you dont want your voice to be competing with projector noise a noise level in the 20 28 dB (whisper quiet) should be achievable;

Rugged Design - to protect the projector from dust and tolerate knocks during transport - look for shutters, caps and lack of protruding controls;

Quick Shut Down (cooling cycle) - so that you can move on without delay if necessary

Simple Remote Control easy to use with large buttons - backlit if possible

Locking System makes your valuable, portable projector less attractive for misuse or theft - password login keypads are a common solution;

Personalized Start-up Image display your company logo for a professional touch

No PC Required Presentations - facility to load your presentation without a PC using a USB interface or similar;

Protective Carry Bag a bag which offers some protection while leaving room to store the power cord, cables etc.

Build Your Own LCD Video Projector

Build Your Own LCD Video Projector
By Andrew Seltz

Mix big screen home theater dreams with a skimpy budget and you have the makings of a fantastic do-it-yourself project. Just think of how impressed all your friends will be watching blockbuster movies on a video projector you made with your own 2 hands.

It was just these motivations that landed me in front of my web browser digging for information for this project. There are a lot of cheesy websites that promise the moon and sell you a plastic magnifying lense and the instructions to stick a television into a box and put this lens on the front. You will get an image, but it will look like you made it yourself. - dark, and blurry.

Is there any way to make this work? The short answer is yes. A video projector is essentially a high resolution LCD video screen with a really bright light shining through it and a projector lense enlarging onto the screen. New portable models use very tiny, and expensive, LCDs along with sophisticated light sources and high quality lenses. If you are willing to end up with a projector that isn't quite so tiny, you can scavenge the parts you need from an LCD computer monitor and add some electronic components and relatively inexpensive lenses. For $200-$500 you should be able to create a high resolution bright projector that will really impress your friends.

The parts you need are:

• High resolution LCD computer monitor
• Projector lens (and possibly 2 fresnel lenses depending on the plans you use)
• Cooling fan(s) - bright lights get hot when you shove them in a box
• Bright lightsource (one approach to the project is to use an old overhead projector)
• Electrical power supply

There are dozens of websites with step-by-step plans for free or for sale. Some sell parts that you'll need. Two that I've found to be excellent are LumenLab and the DIY Projector Company. They both sell parts and parts kits. LumenLab sells a very nicely produced PDF instruction guide with detailed plans. DIY offers plans free, but expects that you'll buy one of their kits to actually make the projector. They both use the LCD in a box with a lamp approach.

InventGeek has a great article explaining the whole process in depth including the theory behind projectors. I recommend you check it out. The DenGuru website shows another approach to the project. They use an old overhead projector for both the lightsource and lens. You strip the LCD panel out of its frame and lay it on the projector like a transparency. Ugly, but it works! Check out their tutorial.

Break out your toolkit and get busy - and let's be safe out there people!

Projector Rental Question: What's a Lumen?

Projector Rental Question: What's a Lumen?
By John Beagle

Answer: The brightness of a projector is measured in Lumens
When Renting or buying an DLP or LCD Multimedia Projector you need to match the brightness of the projector to your audience and room size. Larger rooms and audiences require higher bulbstrength brightness.

Projector bulb strength brightness is measured in ANSI lumens or lumens. You also need to take into account the primary use of the projector, full motionvideo vs. static data.

Projectors range from around 650 to 5000 lumens in brightness.

Note: A standard 100 watt incandescent light bulb emits approximately 1700 lumens.

Presentations where the lights are on are the most desirable, but require higher lumen bulbs because you can interact and demonstrate off-screen with your audience.

Another consideration is portability of the projector. Lower lumen units are the most portable. As a general rule, as you increase bulb strength brightness, you reduce portability. High lumen projectors are larger and weigh more than low lumen projectors.

Less than 1000 lumens
-good for low ambient light, presentations.

1000 -2000 lumens -These
are the most popular units being sold and rented today.
Very practical and will work with some ambient light.

3000 lumens -Much
Larger unit than the 1000 to 2000 lumen units. Good for audiences of less than a hundred with ambient light.

5000 lumens
- For audiences of 100 or more under brighterlights

6000+ lumens - For largeevents like conventions, conferences, classroom training and trade shows wherethousands of people need to view a presentation at thesame time.

How DLP Projectors Work?

How DLP Projectors Work?
By Paul Cris

DLP (Digital Light Processing) projectors can be attached with computers, DVD players, VCR players, HDTVs and video games. It comes in various models and with enhanced features. DLP Projectors are also called as Multimedia projectors.

In mid 1990s Texas Instruments developed Digital Light Processing. DLP technology is based on DMD or Digital Micromirror Device. It is a switch, which controls the intensity, and placement of projected light via 4,80,000 mirrors. In a DLP-based display there are unlimited colors. You can control the saturation and clarity to make bright video as clear as you want. The DMD is coordinated with a graphic signal, a light source and a projection lens.

The micromirrors of DLP are fixed on a panel of small pivots, which enable them to slant either way. If it slants towards (on) light source it creates bright pixels on the screen and when it slants the other way (off) it creates darker pixels. When the bit-stream image code enters the semiconductor, the semi conductor directs the switch to on or off. If the switch remains on more times than off, it reflects a light gray pixel. Otherwise it reflects darker gray pixel.

In DLP systems white light is passed through a color wheel and it runs to the surface of the DMD panel. The color wheel converts the white light into red, green and blue. From these three colors a DMD chip can create 16.7 million colors. So a 3-DMD chip DLP system can create a mammoth 35 trillion colors. Then our eyes understand these colors and see an image.

By Marcus Peterson

DVD is a type of optical storage technology. Digital form of storage has completely replaced magnetic storage media like floppy disks. DVD is the acronym of Digital Versatile Disk and is better than CD in terms of audio and video quality. It is versatile and can be played in DVD players and computers.

DVD comes in various formats like DVD-R and DVD-RW, the R and W means read and write capacity of the disc. DVD players can play units can play a various units audio and video discs in different formats such as CD-R, CD-RW, mp3 and VCD. DVD players also support jpeg formats. Some DVD players have recording features.

DVD projectors are used to project audio and video images from DVD players and VCR. Care should be taken to ensure that the medium used is compatible with the DVD projectors. For instance, some DVD projectors dont support inputs from computers. While hiring DVD projectors, the accessories are DVD players, DVDs, sound systems and screens. These have to be carefully chosen. They also come with IR remote controls and laser pointers. The output can be fed into high resolution plasma and LCD displays.

Some of the branded names available for rental come from 3M, Canon, BenQ and InFocus. They are available in different models with different features. DVD projectors can be hired for as low as $80 and the accessories are charged with their own rental rates. The rental companies require credit card information and an ID. Since DVD projection is of high quality, the major segment is the corporate and business houses for their presentation requirements.

DVD projectors, because of their versatility and high quality, are used in wedding receptions and other staging events such as conferences and trade shows. DVD projectors have made the film projectors less attractive.

Auditorium LCD Projectors

Auditorium LCD Projectors
By Ken Marlborough

Auditorium LCD Projectors are generally up to 40kg in weight, with 3,000 lumens (a measure of brightness) and above, have SVGA (brightness range from 1700 - 2000 lumens) or XGA (brightness range from 2000 - 3000 lumens, are more expensive than SVGA) native resolution. Auditorium projectors are mostly LCD projectors and usually come with a ceiling or rear mount facility. They usually have motorized zoom lens, are generally operated via remote control and offer multiple input and output ports for both PC and video. Auditorium LCD Projectors generally require external speakers and are targeted at spacious venues like theaters, auditoriums and convention halls.

In other words, auditorium LCD projectors are heavy duty, and super bright, allowing them to provide the added illumination for very large applications. These projectors deliver high brightness that can be used in a wide range of places. They generally come with a lens shift function and a wide range of optional, interchangeable lenses also contributes to installation ease. These LCD Projectors have a variety of functions for high picture quality and network compatibility is also included. Providing realistic colors, sharp contrast, and super bright images, they enable presentations with persuasive impact in a variety of situations.

Some factors which help in choosing a better Auditorium LCD Projector are: Lumens, Resolution, Lens Power, Keystone Correction, Scanning Frequency, Contrast, Lens Throw Ratio, Aspect Ratio, Image Offset Range, Computer Compatibility, Video Compatibility, Image and Mouse control, Projection Modes, Color Reproduction and Lamp Life.

These projectors generally have a specially designed auto focus lens, which allows for quick and easy switching between multiple screens with minimal user adjustments. Their automatic color correction feature provides true color reproduction even when projecting onto colored or textured walls for a perfect presentation anywhere. Some of them have a 3-D Reform technology, which lets one set up the projector virtually anywhere in the room and still get an aligned image.

While choosing the right LCD projector for an auditorium, the dimensions of the auditorium, the ambient light conditions and the distance where the projector will be placed from the screen should considered and projectors whose specifications exceed the requirements should be considered.

An Introduction To Projectors

An Introduction To Projectors
By Elizabeth Morgan

A projector is an apparatus for presenting an enlarged image on a screen from a transparency such as a photographic slide or a film. In a motion picture projector, each frame is held stationary at an illuminated aperture for a brief period, and then advanced by an intermittent sprocket or reciprocating claw, the light being cut off by a rotating shutter during the movement. The soundtrack on the film is reproduced at a separate sound head where the film is moved continuously at a constant speed.

An average projector usually has a picture resolution of 800 x 600 pixels. Most of the projectors weigh four to six pounds and come with a carrying case. All of the projectors have varied brightness and contrast levels usually the brightness varies from 1300 lumens to 1500 lumens. A projector with a brightness of 1400 lumens proves to be a good choice for small to medium-sized, well-lit rooms.

Some of the indispensable parts of a projector are the feed spool, xenon arc lamp, projection lens, optical sound head, take up spool, an aperture, normal lens and rotating shutter. But with the advancement of science, new technologies have come into play. The projectors have become much more advanced in terms of clarity of picture and quality of the pixels. Also, the projectors have found use in everyday households, as new versions of domestic projectors have arrived on the market. The abundance of LCD projectors, DLP projectors and video projectors has enabled the common man to enjoy the experience of a big theater hall in his living room.
