Most LCD projectors require filters that are sometimes recommended to be cleaned after every 100 to 300 hours of operation. DLP technology enables a filter free design which means lower maintenance and operating costs.

DLP projectors feature incredibly high native contrast ratios. Blacks are really black and whites are really white, making your projections extremely easy to read.
