It also discusses other aspects like resolution, brightness and contrast ratio that should be considered while choosing a projector. In conclusion, it compares the different projector technologies.
There are several types of projectors that can be used for presentations or entertainment. A front projection projector is good for large audiences but makes interaction difficult. A rear projection TV projects an image through lenses and mirrors to create a large screen image in a shallow depth. CRT projectors use small color CRT tubes to focus and enlarge the image onto the screen, while LCD projectors send light through a prism to separate colors and display the image. DLP projectors use a digital micro-mirror device to project images. The brightness level in lumens is an important factor, as is the throw distance between the projector and screen. Projector lamps are a key component that transfers the image to the larger screen.
Step-by-Step Guide to Picking the Best Projector for Your Home Theater.pptxleelindesy
Turning your home movie-watching into a true cinematic experience starts with picking the right home theater projector. With so many options out there, it can feel overwhelming. This guide will simplify the process and help you choose the perfect projector, ensuring your home theater setup delivers stunning visuals and immersive sound.
The document discusses different types of projectors, including their advantages and disadvantages. Front projection allows for a larger image size but requires careful room lighting design. Rear projection allows for easier interaction and is better for rooms with normal lighting, but has limited screen size and requires space behind the screen. CRT projectors have long service life but are large, heavy, and use more power. LCD projectors display color images using polarized light through LCD panels but require more setup. LED projectors are becoming more popular due to less maintenance and longer life compared to conventional lamps.
Digital Light Processing (DLP) is a display technology that uses a Digital Micromirror Device (DMD) chip to create high-quality digital images for projection or display. DLP was invented by Texas Instruments in 1987 and uses an array of tiny tilting mirrors on a chip to reflect light and produce an image. Each mirror represents one pixel. DLP provides superior brightness, resolution, and color fidelity compared to other display technologies. Some common applications of DLP include home theater projectors, televisions, and cinema projectors.

CSE Digital Light Processing PPT.pptx for seminaranuvayalil5525
This document provides an overview of digital light processing (DLP) technology. It describes DLP as a display technology that uses a digital micromirror device (DMD) chip. The DMD chip contains an array of tiny tilting mirrors that reflect light to produce an image. It works by rapidly switching individual mirrors on the DMD chip to either an "on" or "off" position, creating a grayscale image. Color is added by passing white light through a color wheel and timing the reflection of red, green, and blue light from each mirror. DLP has advantages like brighter, sharper images and more reliable performance compared to other display technologies.
There are two main types of digital projection display systems. The older type uses three liquid crystal display (LCD) panels to project colored light onto a screen, similar to a slide projector. A newer type called Digital Light Processing (DLP) uses an array of tiny mirrors that reflect colored light from a spinning filter wheel to produce the image. DLP offers advantages like lighter weight, higher contrast, and a lack of pixelation in the projected image.
How to Reduce Readmissions by Changing Patient EducationChuck Jones
The challenge is no longer finding the perfect medication but rather convincing the patient to take their medication as prescribed. It's no longer providing discharge instructions but educating the patient so they understand the need to follow through on behavior change to avoid repeating habits that brought them to the hospital in the first place.
What technology challenges are you facing today? A recent forum of CTO's found that while funding is an on-going issue there are other challenges that can be equally as daunting.
To compound the technology issues, a recent survey found that only 51% of school districts had their own IT Director. This means 49% of Districts are staffed by a part-timer (i.e. Principal or Teacher) or the position is not staffed. Given the growing importance of integrating IT and Digital Learning this could be a major obstacle for many districts.
We've highlighted some of the challenges and provided resources where available to help you chart a course.

Educators Guide To Copyright And Video MaterialsChuck Jones
The purpose of this document is to help educators and students better understand the complex and often confusing copyright laws and how they pertain to the use of copyrighted material in the classroom.
Educators should feel confident that they can use copyrighted material for instructional purposes and not worry about legal ramifications.
The document outlines 5 reasons why hospital TV systems are often inadequate: 1) Lack of clear ownership and advocacy for the TV system results in it being neglected; 2) Hospital TV does not generate direct revenue; 3) Administrators and their families would likely find issues with the TV system quality if experiencing it firsthand; 4) Outdated technology like pillow speakers and small TVs impair the viewing experience; 5) Hospital TV systems are sometimes viewed as a low priority expense compared to other areas. The document encourages hospitals to recognize TV as an opportunity to improve patient satisfaction.
How To Use Video To Lower Training CostsChuck Jones
The document discusses how video can be used to reduce training costs for fire and rescue personnel. It outlines that video is an effective training tool that allows people to remember 70-90% of what they see and hear. It then discusses different options for delivering training videos like duplication, satellite, cable channels, and streaming. However, these options have drawbacks like high costs, inability to access videos on demand, and network issues. The document promotes the VideoCourier solution which allows 24/7 on-demand access to training videos using a city's network bandwidth at off-peak hours, addressing the issues with other options.
Video can be an effective teaching tool in the classroom. Teachers find that video stimulates discussion, reinforces lessons, and helps students learn. Students who regularly see videos in class perform better on tests and are more engaged. Research shows videos improve understanding when paired with active learning assignments before and after viewing. Teachers should keep videos short and relevant to lesson objectives in order to maintain student attention.

2. Analog TV is dead and quickly moving out of the classroom. The
projector seems to be most popular replacement for several
obvious reasons:
The picture is much larger than the typical 19” TV most
classrooms usually have installed and this is great because
now the students in the middle and back of the room can
actually see what’s on the screen.
The picture seems much brighter in most of the projectors
I’ve seen which is also great because the teacher can leave
the lights on and still use the projector in many cases.
The bad news is there appears to be more than 1,000 different
projector models on the market and they range in price from a few
hundred dollars to over $50,000.00. With that range of product
offerings how is a school to decide on a particular model that will
work best for all classrooms?
In an effort to find the best value we began a search with Google
and reluctantly determined that there was too much information
and too many models and manufacturers to make a comparison
simple. So, rather than make a brand or model recommendation it
makes sense to try and identify the important features to look for
when choosing a projector.
Key Considerations
The following are thoughts and ideas on what should be
considered. There are many details, features and options but we
decided to take a big picture view and focus on these areas:
Lumens
A lumen is a measurement of light output or brightness. The
American National Standards Institute (ANSI) established a
standardized testing procedure for projectors that involves
averaging several brightness measurements taken from different
locations. This number is called the ANSI lumen measure and
because it is an industry standard you can use the number
compare one projector to another to compare their relative
brightness. The larger the number, the brighter.
But how do you know what ANSI lumen number to look for? Does
room size or audience size matter? What about room lighting?
For classroom use it makes sense to use a projector that can
function properly without having to turn off all the lights or darken
the room to be able to see the picture. Teachers need eye
contact to foster interaction and read student engagement to
keep discussions active and moving. This also facilitates moving
2
3. back and forth between video and discussion mode to keep things
interesting.
In looking at the different types of projectors it appears that the
very small portables (ultra portables) have between 1000 and 2500
lumens and the larger projectors for training rooms, conference
rooms and classrooms have 2500 to 7000 lumens. The web site
projectorpeople.com recommends the following guidelines for
lumens and lighting.
• 1000-1200 lumens for lights-off, low ambient light
• 1500-2000 lumens with some ambient light
• 2000-2500 lumens with bright ambient light
Ambient light is considered room light or existing room light that
originates from sources other than the projector. The brighter the
ambient light the brighter the projector needs to be.
Another consideration is audience size. The larger the audience
the larger the picture needs to be so the more light necessary to
overcome ambient light in a larger room. Projectorpeople.com
recommends the following guidelines for large audiences:
• 2500 lumens for less than a hundred with ambient light
• 3000 lumens for audiences of 100-200 with ambient light
• 5000 lumens for audiences of 100 or more under bright lights
Resolution
Resolution is a way of relating to the sharpness of the picture. The
higher the resolution the sharper the picture, or the more detail you
can see. Resolution is typically displayed as 1024x768 where the
first number represents the width in pixels and the second number is
the relative height in pixels.
Most projectors are available in several resolutions such as,
• VGA (480x640)
• SVGA (800x600)
• XGA (1024x768)
• SXGA (1280x 1024).
One number is typically identified as the “native” resolution or
default setting and is usually the optimum setting for that particular
projector.
Here are some things to think about. PowerPoint presentations,
charts and most graphs will project just fine using a resolution of
3
4. 800x600. High resolution graphics, photos and small print on a web
page or other fine detail will probably need 1280x1024. Your
classroom computer or laptop resolution is important as well and
should be the same as the projector so everything displays
properly.
Aspect Ratio
The aspect ratio relates to the dimensions of your picture expressed
in units as the number of units wide by number of units high. Old
analog TV’s have a 4:3 aspect ratio, which means the picture is
almost square in appearance. The new flat screen TV’s are 16:9
and are much wider than they are tall. The U. S. is currently
transitioning from analog to digital TV where the older format is 4:3
and the newer format will be 16:9 so you will likely see and view
both formats until all formats of video and other content transition
to the new wider format. Check the specifications of any projector
you are interested in to see what aspect ratio it supports. Some will
only support 4:3 others will handle both.
Types of Projectors
Source: ProjectorPeople.com
LCD was the most common projector type but DLP is newer and
becoming more popular. DLP is typically the technology used in
the smaller portable and lightweight models.
LCD (liquid crystal display) projectors usually contain three
separate LCD glass panels, one each for the red, green, and blue
components of the image being fed into the projector. As light
passes through the LCD panels, individual pixels can be opened to
allow light to pass or closed to block the light. This modulates the
light and produces the image that is projected onto the screen.
DLP stands for Digital Light Processing and was developed by Texas
Instruments. Instead of having glass panels through which light is
passed, the DLP chip is a reflective surface made up of thousands
of tiny mirrors. Each mirror represents a single pixel. In a DLP
projector, light from the projector's lamp is directed onto the
surface of the DLP chip. The mirrors wobble back and forth,
directing light either into the lens to turn the pixel on, or away from
the lens to turn it off.
LCD Projectors: Strengths
-Richer color (better in rooms with ambient light)
-Draw less power
-Produce less heat
-Quieter
-Sharper image on data

5. LCD Projectors: Disadvantages
-More visible pixels
-Some screen door effect on certain video images
-Physically larger
-Poorer contrast
-Blacks come out lighter gray versus DLP projectors
DLP Projectors: Strengths
-Smoother video
-Smaller
-Pixels less visible
-"Blacker" blacks
-Higher contrast
DLP Projectors: Disadvantages
-Color filter wheel often produces soft but audible whine
-Poorer reds and yellows at full power
-Color saturation
-Need more lumens than LCD, for rich colors

Weight
Weight can be a concern if you plan to move your projector from
classroom to classroom or if you mount it on the wall or the ceiling.
Obviously, if you are going to be moving your projector around
without the benefit of a cart the smaller the better and there are
many portable models from which to choose. Expect the portable
models to weigh between 1.5 and 4 pounds. Larger models will
weigh 7 – 15 pounds and heavier. The heavier the projector the
more expensive to mount on the wall or ceiling.
Connectivity
With all the new devices available today some care should be
taken to make sure the projector you select has all the connectors
you will need. Examples include a VGA connector for your
computer, USB for a document camera, S-video, composite video,
left and right audio, audio connectors for external speakers, and
HDMI for high def devices.
User Controls
Take a test drive on the user controls. How easy is it to actually use
the projector’s controls? Is navigation easy or difficult? Is it intuitive
or will you need to keep the manual tethered to the machine?
Opt for simple controls whenever possible to reduce support calls.

6. Remote controls are usually included with each projector and third
party control panels can be used to control not only the projector
but other devices in the classroom as well.
Lamp Life and Energy Conservation
Projector lamps are expensive so look for projectors that have a
lamp life of 2,000 hours or greater. Also look for projectors that
have sleep modes or power conservation controls. These prolong
lamp life and also save on the school’s power bill.
Zoom
Choose a projector with a zoom lens for more picture flexibility. The
zoom feature can be automatic or manual and should be a
feature on the remote control.
Keystone
Keystoning is a distortion of the projected image and is caused by
either the projector or display surface being on an angle. As an
example, if the projector is on a table and displays on the wall the
top of the picture is likely to be wider than the bottom. Some
projectors can adjust keystoning within the projector. It’s a good
feature to have.
Throw
Throw is the distance between the projector and the display. A
short-throw projector can be very close to the screen where as a
long-throw projector must be farther back. Make your decision
based on where you plan to install the projector. What’s the
distance between the projector and the screen? To avoid having
students step on wires when using a table or cart, select a short-
throw projector so it can be positioned closer to the screen and
away from student desks Some projectors have interchangeable
lenses for short or long throw situations.
Most manufacturers provide calculators on their web sites to help
you determine the throw and screen size for each model as well as
the right size for a particular classroom dimension.
Lens Shift
Lens shift is a great feature to have that enables the lens to shift up,
down, left or right to provide greater installation flexibility. By
shifting the lens one direction or the other you avoid the need to
physically move the projector or the mount to true-up the angle of
the picture to the screen or display surface. In a brief search of
several brands this feature appears on mostly high-end models but
it does not hurt to ask about it in your quest.

7. Network Management
Choose a projector with a network connection if you will deploy
large numbers. Having this connectivity available usually means
the projector has administrative software that allows monitoring of
usage, lamp life and other measurable areas. A key consideration
here is the ability to remotely turn the power off to all units to save
on the electric bill and preserve the lamp.
Summary
In the end, it’s about setting priorities when in search of the perfect
projector. If you want some feedback I would encourage you to
talk with other schools that have purchased projectors and have
some experience. They can probably explain the mistakes they
made the first time they purchased a projector and you can learn
from their experience. If their projectors are a year old or older
don’t expect to find the same model available. This market
appears to change and update models on a very frequent basis.
You can also attend trade shows to visit all of the manufacturers.
Some of these shows will even hold a projector “shoot out” and
show them side by side so you can compare models.
Be careful when making replacement purchases as well. Minor
changes in the throw or angle of the lens from one projector to the
next might mean having to move all of your mounting brackets,
which can be an expensive undertaking so it makes sense to try a
replacement model on an existing bracket before you make the
purchase.
