The ultimate education projector

The D755WTIR ultra short-throw interactive projector delivers a large 80” to 100” image from a distance of about 30cm from the projection surface. The projector delivers a high brightness with 3,300 ANSI Lumens and an outstanding contrast ratio of 10,000:1 for a clear and crisp image. The D755WTIR offers full IWB functionality with IR pen support and finger touch interactivity thanks to the optional finger touch DT01 Laser curtain. The finger touch module enables users just to use their fingers to write, draw, or interact in an intuitive way.

DLP® Technology

DLP (Digital Light Processing) is a display technology from Texas Instruments (TI). The technology inside is often referred to as DMD (Digital Micro-Mirrors). It consists of an array of mirrors where each mirror represents a pixel element. For example, a high-definition DLP projector or rear projector with 1920 x 1080 pixel resolution would have over 2 million tiny mirrors. Each mirror is attached to an electronically driven hinge that controls the amount of colored light that is reflected from

BrilliantColor™

BrilliantColor from Texas Instruments is a multi-color processing technology that produces vibrant images. BrilliantColor technology uses up to six colors, instead of just the three primary colors, red, green and blue, to improve color accuracy and brightens secondary colors.

3D Ready

A projector that is 3D Ready can accept a 120Hz frame-sequential 3D signal from a computer. These projectors are not compatible with the HDMI 1.4 3D specification used on 3D Blu-ray players and set-top boxes. 3D ready uses DLP Link Technology from Texas Instruments.

HDMI

HDMI (High Definition Multimedia Interface) is an uncompressed, all-digital audio/video interface that supports audio/video sources such as a set-top box, DVD player, A/V receiver, and video monitors such as a digital projector or digital television (DTV). HDMI is backward compatiable with DVI 1.0 specification and supports HDCP.

Note on using the projector distance planning calculator and tips for projector installation:
Calculator accuracy +/-5%. The calculator is designed to help you plan your installation and find the right projector. It is not designed to provide exact dimensions. When calculating the throw distance, bear in mind that the distance is measured from the front of the lens to the projection surface, except for Ultra Short Throw projectors with a mirror system. Where possible, attempt to position the projector in the middle of the zoom range , which is where the optics is optimized for. Try to avoid the extreme outer boundaries as the projector lenses has variance and performance tolerances that could make the screen not being filled, or the image being larger than the screen, caused by small variances in the optical systems. If you need to be at the extreme outer boundaries, we recommend that you order the projector and test the actual distance in your environment before fixing any mounting parts to the wall or ceiling.
