Home Theater Projectors

One of the main reasons people buy a home theater projector is for the cost
per image area. While buying a projector has the benefit of giving a huge
viewing area, there are some limitations that effect the image quality.
Some things to compare are resolution, brightness, contrast ratio, weight,
and optional features when shopping for a home theater projector. The most
popular home theater projectors like Epson, Optoma, Sharp, Sony, Sanyo,
Infocus, Panasonic, and Samsung.

Types of Home Theater Projectors

LCD Projector Liquid Crystal Display (LCD) create bight images by passing light through
three small LCD panels that are vibrant in color and sharp. LCD projectors
are appropriate for dimly-lit rooms and auditoriums.

DLP Projector Digital Light Processing (DLP) use a single digital chip that makes them
weigh less than LCD projectors. They offer smooth video performance, high
contrast ratios, and little pixilation. Perfect for home theater use.

3LCD Projector 3LCD projectors use three LCDs to create bright, crisp, vibrant smooth
images. 3LCD projectors separate light from the projection lamp into red,
green, and blue colors. Each color is shone through individual liquid
crystal display panels that give high definition and movement to the
projected image. Since there are 3 LCDs there are no problems with color
breakup or a ‘rainbow effect’, where the image blurs and separates into its
three component colours around the edges. 3LCD has improved contrast level,
excellent black and shadow reproduction, and can produce a quality bright
and clear image from a low-output lamp.

Projector Resolution The resolution of a home theater projector is the sharpness and clarity of
the picture produced. It measured by the number of pixels the projector
uses to creat the image. Resolution is expressed by two numbers. The first
number indicates the horizontal pixels and the second number represents the
vertical pixels. For example a 720p (1280 x 720 progressive scan) or 1080i
(1920 x 1080 resolution iterlaced scan). The higher the resolution, the
sharper the image.

Throw Distance Throw Distance is a measure of the size of image a projector can produce
from a given distance. You can find the throw distance of your projector
usually by visiting the manufactures website and using their throw distance
calculators.

Keystone Correction Keystone Correction is a feature that allows a projector image to be
adjusted when the projector is at an odd angle from the screen.

Contrast Ratio Home Theater projectors will give the give the contrast ratio, the
difference between the White Level (Brightest) and Black Level (Darkest)
sections of an image with a ratio. Projectors with a higher contrast ratios
produce the most well-defined pictures.

Lumens Lumens are a measurement unit of total illumination. Projector light
output is measured in ANSI(American National Standards Institute) lumens. A
projector with a higher lumen number will produce a brighter image for a
given image size. Typical Lumens Ranges Less than 1000 lumens Least expensive. Low light output means that you will
want to make your presentations in a dark or dimly lit room so the image on
the screen is not washed out by ambient room light.1000 to 2000 lumens Typical range for SVGA and XGA products. Presentations
should be done with the room lighting reduced somewhat for best screen
viewing.2000 to 3000 lumens Offer flexibility in terms of ambient room light, a
reasonable amount of room light can be tolerated without washing out the
image. Can illuminate a larger screen without much loss of image quality.3000 lumens and up Ultra bright and most expensive projectors.

room light can be tolerated without washing out the image. Can illuminate a

3000 lumens and up Ultra bright and most expensive projectors.

Lamp Life The typical lamp life for a projector on average is between 1500-3000
hours. A replacement lamp can cost between $200-$400.

Home Theater Projectors are surely the best value compared to cost per
screen size of plasma and lcd tvs.
