What should I look for in a projector?
There are three main types of projectors: Cathode Ray Tube (CRT), Digital Light Processing (DLP) and Liquid Crystal Display (LCD). Here are some things to look for when buying a projector.
• Without the right amount of brightness, your image can look wrong, even in a dark room. The light output of the projector is usually quoted in ANSI Lumens, and the higher the rating, the brighter the projector.
• Contrast ratio complements brightness, as a high contrast ration can produce brighter whites and darker blacks.
• Pixel density is important, especially for LCD/DLP units which have a fixed number of pixels in their chips.
• Colour reproduction is another factor. Check for natural flesh tones, colour depth, and how the colours look in both the brightest and darkest areas of the image.
• Make sure the projector has the inputs you need, such as composite and S-video for analogue sources, component inputs for DVD, and DVI or HDMI inputs for HD sources.
• Screens come in various fabrics, sizes, The type of screen that’s best depends on the projector, the viewing angle, the amount of ambient light in the room and the distance of the projector from the screen.
• Portability is important, as this lets you move or travel with the projector and simplifies installation and setup.
