DISPLAY DEVICES

WATCHOUT can be used with most display technologies, including DLP and

LCD projectors, LCD monitors, video wall cubes and plasma screens. Generally

speaking, you can use any display device that’s compatible with the display

card in the display computer.

For projection purposes, DLP projectors with a high contrast ratio (2000:1 or

better) is recommended. See “Display Issues” on page 239 for further details

on various kinds of displays, and how to connect them to WATCHOUT.

PROJECTION SCREEN

As in all multi-screen projection applications, it is important to choose the

screen material with caution. Make sure you buy your screen material from a

screen manufacturer familiar with the requirements of multi-image projection,

or similar applications.

For front projection, avoid using high-gain, or “silver” screens. Such screens

often cause uneven brightness or banding when using multiple projectors and/

or when viewing from non-optimal angles. See “Banding” on page 245.

A related problem when using rear projection screens is the “hot-spot” caused

by the projection lens showing through the projection surface. See “Rear

Projection” on page 245.

SOUND

Sound can be provided through any of the display computers, or through the

production computer. Simply connect the sound output from the computer

(usually a 3.5 mm mini-jack) to the amplifier or powered speakers.

If you need to run the computer’s line level audio signal a long distance, you

should use an audio line level transformer. This converts the unbalanced signal

coming from the computer to a balanced signal, thereby reducing the risk of

hum and noise when connected to a professional audio amplifier.
