4 Installation

4.1 System considerations

Please refer to Chapter 5 Overview for an explanation on the various features of the

projector.

Installation should only be performed by trained and skilled personnel in order to achieve the

desired results.

Safety ﬁrst: Projectors and other equipment that are not mounted properly represent

a potential danger to people and may result in injury or death!

Creating a successful system installation requires proper skills, competencies and knowledge

of the particular system requirements. In addition to knowing the expected performance,

ambient conditions and all the components that form the complete system, including Image

Generation (IG), cabling, control system, screens and projectors.

An installation often consists of multiple projectors, long cables and several IG’s, as well as

intermediate system components like signal converters and line buffers.

Make sure that:

• IG properties like pixel resolution and frame refresh match those of the projector

• Choice of signal interface and cable lengths match.

o HDBaseT and 3G-SDI are so called long-haul interfaces, suitable for bespoke

installation on the premises using relatively long cables.

o DP, HDMI, DVI and VGA are all short-haul interfaces using pre-assembled cables

with limited cable lengths. Using extended cable lengths may result in reduced

image quality as well as loss of control information such as EDID (Extended Display

Information Data).

• Signal ampliﬁers, switches and other components should convey EDID and other control

information. However, unfortunately many times EDID data is lost in translation under

way, potentially resulting in images of reduced pixel resolution and wrong aspect ratio.

A successful installation takes all relevant parameters into account to achieve great imagery!
