How to Buy a New Projector

If you are looking to buy a new projector for a classroom, meeting room or home theater, the image you project on the screen should make a great impression on your audience. Researching projectors can be confusing, with many acronyms and technological terms. Our projector guide will help answer common questions regarding terminology, features and other important considerations when you are choosing a projector.

Color Brightness and White Brightness

Projector brightness is the light output of a projector measured in lumens. There are two important brightness specifications, White Brightness and Color Brightness. If you only see one “Brightness” spec published for a projector model, it is usually the White Brightness rating, and the Color Brightness of the projector may be much lower.

Contrast Ratio

Contrast ratio is the difference between light and dark on a screen, expressed by a number. If you take the brightest white on a screen and the darkest black and compare the luminosity, you get the contrast ratio. For example, a 1000:1 contrast ratio means that the brightest white is 1000x brighter than the darkest black.

Resolution

Resolution is the number of dots or pixels used to display an image. Higher resolutions mean that more pixels are used to create the image, resulting in a crisper, cleaner image. High resolution is important for projecting detailed charts and graphs, text, and high-definition video. The resolution is indicated by a number combination such as 1920 x 1200. This indicates that there are 1920 dots horizontally across the display by 1200 lines of dots vertically, equaling 2,304,000 total dots that make up the image seen on the screen.

Product Support and Reliability

Reliability and the cost to operate your projector depend on one main factor: lamp maintenance. Look for a projector with a long lamp life; at least 3,000 hours is preferred, and about 5,000 hours is typical.
