HDP404 Throw Distance:

Thank you for choosing Knoll projectors! The HDP404, is a DLP™ projector with a 16:9 digital light processing imager. It can display a wide range of formats from standard TV, extended definition TV through high definition TV and films as well as computer images. Its all glass lens allows for a wide level amount of zooming.

Some of the advances unique to the the HDP404 are a mechanical iris accessed by the remote control to increase the already very high contrast ratio from 2500:1 to 7500:1. The video optimized brightness at D65 is a minimum of 1200 ANSI lumens. This is nearly 4 times brighter that a commercial movie screen image. The HDP404 is future proof out of the box with HDMI 1.3 with Deep Color support (can display over 1 billion colors, a first for any projector made). The color gamut calibrator and ISF day and night presets are available to "lock in" optimized calibrations settings for day and night and other calibrations as desired.

The Knoll CM26 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 HDP404 can be tilted about +/- 13 degrees maximum when mounted using its digital adjustable keystone. For best overall image the HDP404 projector should ideally be level if the screen is vertical (which is usually the case).

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).
