What is DLP technology?
DLP, or Digital Light Processing, is a light processing system that utilizes hundreds of thousands of tiny mirrors to reflect images. It is widely considered to have one of the most accurate reproduction of color and images available today.

Dell uses DLP technology in its projectors to help ensure you get the most accurate reproduction of images available today.
Why choose DLP over LCD?
|Picture reliability is how the images from your projector will look over time. When looking at a projected image, if you see an unusual amount of yellow or greenish hues in your images, that's what we call image degradation or color decay. Projectors that use DLP technology are designed to be virtually immune to color decay. However, LCD projectors can't make that same claim.|
|LCD projectors require filters to keep dust out. These filters must prevent possible degradation to the optics and LCD panels. Frequency for cleaning a projector's filter is normally every 100–300 hours (1x every month to three months) and replacement of the filter is often recommended at each lamp replacement (Every 2,000–3,000 hours). There are DLP projector models that enable sealed optics which do not require filters, eliminating the need for this periodic maintenance cleaning and replacement. The result? Low maintenance needs which can translate to lower operating costs. If you're used to working with LCD projectors, you will understand.|
What determines image quality?
Fill factor: The usable space of each pixel in the image.
|Contrast ratio: The difference between the white and black parts of the picture.|
The high native contrast ratio of DLP technology makes text from PowerPoint and Word look sharper and clearer in bright rooms.
|Video performance: How streaming video and graphics are reproduced. |
DLP has a faster switching speed which means a smooth, sharp video.
