What is the contrast ratio?

What is an ANSI lumen?

Lumen is the unit of measure for the light energy which flows in air. An ANSI lumen is a standardised measurement of the average light output of a projector measured at different areas of the screen.

What is the difference between 3 LCD and DLP projectors?

3LCD is the most widely used projection technology system in the world. 3LCD technology employs three high-temperature polysilicon liquid crystal displays (HTPS LCDs), hence the name 3LCD. This is how 3LCD technology works: white light is divided into red, green, and blue using two dichroic mirrors, special mirrors that transmit light with a certain wavelength. Each colour is then passed through a dedicated LCD, before being combined with the other colours in a prism. The image is then ready to be projected onto the screen. DMD™* (Digital Micromirror Device) is a display technology where hundreds of thousands of carefully positioned micromirrors are arranged on a semiconductor substrate. Each mirror corresponds to a pixel and projects an image by reflecting the light from the source. 1-chip, and 3-chip systems are available. DLP™ (Digital Light Processing) is the name for the optical system that uses DMD™. *DLP™ (Digital Light Processing) and DMD™ (Digital Micromirror Device) are trademarks of Texas Instruments Incorporated.

Are Hitachi projectors compatible with Apple Macintosh computers?

Hitachi projectors are compatible with all Apple Macintosh computers for direct connection from the MAC computer to the projector. Some Macintosh computers may require an additional adapter. Network features are not supported unless the MAC has the capability of also running Windows OS.

How many ANSI lumens do I need?

There are 2 main factors determining how many ANSI lumens you need. Screen size and ambient light. The larger the screen and the more ambient light present, the higher the ANSI lumens required will be. Other factors affecting required brightness include, Screen type and type of images displayed.

NB. For education uses in the UK there is a limit of 1500 Lumens.
