Key Features
LCD projectors create images through a liquid crystal display and are the most modern form of projection equipment. Overhead projectors are older projectors for hard copy transparencies. DLP , or Digital Light Processing projectors are of the same generation as LCD and offer high quality resolution and brightness. CRT projectors are older technology and based on three color light projection.
Type of technology that is used to project the images.
Projector brightness is measured in ANSI lumens. ANSI stands for "American National Standards Institute", who created a scale by which to measure the overall brightness value for projectors. The measurement represents the average value of 9 points on the projected screen image. The higher the ANSIv lumens value the brighter and sharper the projected image will be. \r\nWith a measurement of less than 1000 lumens, viewing can be hard unless in a darkened room. With a measurement of more than 3000 lumens, and it may be possible to see even in a sunlight filled room. There are several additional variables to consider as well as lumens, such as lamp bulb type, LCD technology and contrast ratios. If any of these variables is adjusted, it will make two projectors with the same lumens measurement display images of different quality. For example, a projector with a halogen lamp will appear darker than a projector with a metal-halide bulb.
Image Brightness
2500 ANSI lumens
The ratio between whitest white and the blackest black. A greater contrast means the greater the ability of the projector to show subtle color details even in light rooms. There are two separate measurements of contrast ratio: Full On/Off contrast is the measurement of light out when the projector displays a all white image (Full on) compared to the light output of a full black image (Full off).The second is the ANSI (American National Standards Institute) contrast; this is measured by projecting 16 alternating black and white rectangles. The average light output from the white rectangles is divided by the average light output of the black rectangles to determine the ANSI contrast ratio. Be sure you are comparing the same measurement standard when comparing contrast ratio of projectors.
Platform describes the compatibility a projector may or may not have. If you are buying a projector as an add on to a computer, it is important to purchase a projector of the same platform.
Form factor describes the size of the projector: Portable projectors are small and light in weight, making them easy to transport. Desktop projectors are larger than portables and made to be placed on a stable flat surface. They are not easily transported, but can be moved with some effort. Stationary projectors are the largest and can be placed on either a vertical surface or attached to the ceiling using special mountings. These are not intended to be moved or transported once in place.
Depending on the type of use and portability needed, weight is an important consideration when selecting a multimedia projector.

Native resolution refers to the resolution of the computer output signal via the projector. Usually, the input signal (native) from a computer is automatically converted to the projector's own resolution. For this conversion process, the resolution is achieved by hardware/software image manipulation called re-scaling.
Native Resolution
1024 x 768
Maximum Resolution refers to the highest resolution that a given projector can display. Resolution is measured in the number of pixels (or dots) per unit of area, (number of pixels wide by the number of pixels high) that can be displayed on the screen or monitor. A greater amount of pixels per unit of area produces a higher resolution.
Max Resolution (Interpolated)
1600 x 1200 (UXGA)
Image Size (Diagonal)
26.87 in. - 311 in.
Image ratio refers to the relation of the width of the image to the height. While you can change the size of the image, the ratio stays constant.
Image Aspect Ratio
5:4, 16:9 (Wide Screen), 4:3 (Standard)
High-Definition is the top of the line, all digital format for broadcasting and viewing TV programming. With HD, you see images at a higher resolution than you have ever viewed on a home screen before. This clarity is delivered in a crystal clear, widescreen format, with CD quality sound: as if a movie theater was dropped in your living room.

Screen Distance
3.9 ft. - 39.4 ft.
Synchronization Range Horizontal
15 - 91.4 kHz
Synchronization Range Vertical

A video format describes how one device sends a video pictures to another device, or more formally, the video format describes the sequence and structure of frames that create the moving video image. Video formats are commonly known in the domain of commercial broadcast and consumer devices; most notably to date, these are the analog video formats of NTSC, PAL, and SECAM: NTSC: (National Television Standards Committee), is the analog television system in use in the United States, Canada, Japan, South Korea, the Philippines, Mexico, and some other countries, mostly in the Americas. PAL: (Phase Alternating Line), is a colour encoding system used in broadcast television systems in large parts of the world (as Europe - except to France and Eastern Europe). SECAM: (Sequential Color with Memory), is an analog color television system is used in France and Eastern Europe.
Analog Video Format
NTSC, PAL, SECAM
Technical Features
Projectors can create a low hum or background noise from the cooling fan. Here the average noise made by the projector is measured in dB (decibels).
Remote Control Features

Lamp
As with all bulbs, projector bulbs only last for a certain amount of time. Measured in (lit) hours, the life-span can range between hundreds to thousands of hours depending on the technology of the bulb.
