Understanding the technology behind digital projectors will help you select the right model to fit your needs. Use this guide to help you understand which features are most important for you.
- Contrast ratio is the contrast between balck and white. The greater the contrast ratio, the more subtle color details can be seen.
- DLP Technology is "Digital Light Processing". This technology uses tiny micro mirrors to project an image. DLP technology allows for a more advanced digital image display. DLP Technology shows all pixels in an image with the same amount of light so there is no fading around the edges.
- LCD is "liquid crystal display", in digital projectors is a technology that allows all of the pixels in an image to be displayed.
- Lumens or ANSI measure light output. The greater lumens, the greater the range of light capability.
- Resolution is the number of individual dots a display uses to present an image. The greater the resolution, the more detail of an image will be displayed.
- Optical zoom zooms in to an image through the optic lens of the projector.
- Reverse/invert allows an image to be reverse displayed for rear projection, or flips (inverts) an image from top to bottom. This is useful when mounting a projector to a ceiling upside down.
- SXGA Resolution gives each image 1,310,720 individual pixels for display. The more pixels used, the more detailed the image will appear.
- XGA Resolution gives each image 783,360 individual pixels for display. The more pixels used, the more detailed the image will appear.
