Digital Projectors

Used with DVD players, computers & multimedia devices



Digital Projectors

The only way in which you can obtain an entirely digital connection between the source (i.e. DVD players or computers) and the projector screens is by using digital projectors, or more specifically, DLP projectors. DLP (Digital Light Projectors) are the most sophisticated form of digital projectors currently available and can be used in conjunction with DVD players, computers, or other multimedia devices.

DLP projectors make use of revolutionary technology to control light to a level that has never been possible before in household appliances by using a chip known as a DMD (Digital Micromirror Device). This chip is a small rectangular panel consisting of up to 1.3 million hinge-mounted mirrors, each less than one fifth of the width of a human hair. These mirrors can flip between the on and off positions several thousand times per second, and at less than one micron apart they are able to essentially fit between pixels, meaning that there is no chance of pixelation (where each pixel becomes visibly separated when projected onto a larger screen).

How much will it cost?

A good quality digital projector will set you back at least $2000, but you can pay around $10,000 for a state of the art version. If you are likely to be traveling a lot with your projector then it is important to buy a lightweight model. Most projectors are around the 7-10lbs mark, but they can be as light as 5lbs, and small enough to fit into your laptop bag. Computer companies such as Hewlett Packard manufacturer these lightweight projectors.

Brightness & Resolution

If you specifically want a digital projector to be able to produce high quality digital images on the screen, it is likely that you be desperate for everything to look as good as possible. Therefore you need to consider the brightness and the resolution of the projector before you make your choice. The brightness of projectors is measured in ANSI lumens, and a decent quality digital projector will probably be around 3000 ANSI lumens. If the room you are using the projector in is full of natural light, you will need a brighter projector in order for the projection to have the maximum effect. The resolution should be chosen in relation to what you plan to use the projector for. Simple PowerPoint presentations should be effectively produced with a base entry SVGA 800x600 chip, but then it is unlikely that you will be specifically looking for a digital projector if this is all you are planning to do. VXGA projectors operate at a resolution of 1600x1200, and when employed with a DMD chip, then the effects are quite breathtaking. However, you may find that a VXGA chip is too expensive when considered with the SXGA chip, which offers a very solid performance at a far lower price.
