Projector Installation — Introduction

Physical and electrical installation of the TransVision

™

4 must be performed

only by a trained professional who is knowledgeable about both the speciﬁcs

of the TransVision

™

4 and the requirements of the local building and electrical

codes.

Physical installation of the TransVision

™

4 may be divided into 3 steps:

(1) Pre-installation planning, which includes plotting the projector-to-screen

distance. This requires knowledge of the screen size and placement. From

this step you will determine where the projector is located.

For throw distance calculation and physical mounting dimensions, please

refer to the customer support section at www. dwin.com

(2) Preparation and Installation of the ceiling mount bracket, including

drilling holes, securing the bracket to the ceiling and assembling the

mounting hardware.

(3) Final Adjustments.

Once the physical installation is complete, the unit should be properly

adjusted.

Focus: Use the front ring of the lens.

Positioning: Use three dimensional physical adjustments made possible

by the mounting hardware.

Size: Use the zoom ring of the lens;

Vertical Offset: The vertical offset is ﬁxed and may be calculated from the

following formula: Offset = .081 x W +4.5”. The calculation includes DWIN’s

2 inch Ceiling Mount Bracket. Please refer to the “projector calculator” sec

tion under “customer support” at www. dwin.com

(1) PRE-INSTALLATION PLANNING

A. Screen Considerations

Although the following advice is no substitute for a dealer’s recommendation

for your home, here are a few guidelines for creating a front projection home

theater that should be helpful to your early planning:

A1. Screen Color and Material:

Because the superior design and quality of DWIN’s proprietary optical system

results in excellent contrast and black levels, images will look best when

projected on a matte white screen from a reputable manufacturer. Many

competing projector companies recommend gray screens but a properly

projected picture will always look better when colors are balanced for white,

just like in a movie theater.
