HD222 Throw Distance:

Thank you for choosing Knoll projectors! The HD222 is DLP™ projector with 16:10 digital light processing chip to give bright clear images. It can display a wide range of formats from standard TV, extended definition TV through high definition TV. Its all glass lens allows for a wide level amount of zooming (1:1.3).

Some of the advances unique to the the HD222 are the new "BrilliantColor" from Texas Instrucments, a 10-bit video DACs for noise-free dark scenes and an excellent contrast ratio (1400:1). The HD222 projector is designed only for use with 16:9 or 16:10 aspect ratio screens. 4:3 images can safely be displayed on the these screens. Dispite its small size the HD222 has an extremely bright image at 1800 ANSI calibrated video lumens.

The Knoll CM28 ceiling mount kit is easy to install and swivels for exact placement. It drops the projector about 3" and the projector lens is about 6" from the ceiling. If more of a drop is needed, the CM20+6 extender adds an extra 6" drop. As many CM20+6 can be added as needed. For fine tuning the drop the CM25EX adjustable extender is available. It drops the projector a further 6.75” to 11” (17cm to 28cm).

The most frequently asked questions concerning DLP projectors are:

How much can the projector be tilted down (when ceiling mounted) or up (when floor mounted)?
About 20 degrees. The HD222 has a digital adjustable keystone but for best overall image the HD222 projector should ideally be level if the screen is vertical (which is usually the case).

Is the width of the 4:3 image the same as the 16:9 image?
No. The HD222 has 16:10 imager and displays 16:9 or widescreen images using its full width of 1280 pixels by 720 pixels high (720p). When displaying 4:3 images black bars are added on the sides of the image.

Projection throw distances are the maximum and minimum horizontal distances from the projector lens to the screen. If the projector is mounted level (this is strongly recommended) the image will drop (ceiling mounted projector) or rise (floor mounted projector).

HD222 Projection Throw Distance 16:9 Video Screen:

MAXIMUM DISTANCE TO SCREEN (16:9) = 1.996 x SCREEN DIAGONAL SIZE
MINIMUM DISTANCE TO SCREEN (16:9) = 1.610 x SCREEN DIAGONAL SIZE
SCREEN OFFSET (IMAGE DROP OR RISE) (16:9) = 0.073 x SCREEN DIAGONAL SIZE
