IN1776QZX OPERATION MANUAL - REV 1.4 11/27/99

IN1776QZX CONTROL BUTTONS

All the IN1776QZX control buttons are color coded with green name labels next to them for
quick identification. The only exceptions to this are the

PWR

button, the four

ARROW

buttons,

the

MAGIC

button, the

VOLUME

toggle and the five buttons at the top of the unit marked

CD,

VCR, CBL, AUX 2

and

. These buttons are used in conjunction with other projection /

display / recording units. This manual ONLY describes the remote buttons that have green labels.
The diagram on page 10 outlines the location and function of each button. Detailed descriptions
for each button are included below and continued on pages 12 & 13.

PWR Button
This button toggles between power on and power off. For user convenience, the

PWR

button has been programmed with a macro which carries out the following functions:

Sets the remote to control the IN1776QZX

Turns on the IN1776QZX

Sets the IN1776QZX to Overscan

OVERSCAN Button
This button toggles the IN1776QZX between overscan and underscan each time it is
pressed. When working with signals at 1024 x 768 resolution the unit cycles through
four steps: Maximum Overscan / Overscan / Underscan / Maximum Underscan.

Overscan - the image fills the entire screen and some of the image may be lost off the edge
(depends on the type of display device used). The overscan mode gives the best picture clarity
and should be used whenever possible.

Underscan - shrinks the image so the entire image fits on the screen. Underscan is achieved by
dropping lines out of the picture so you may notice some distortion on small text. For highest
quality use the IN1776QZX in overscan mode.

Note: The

OVERSCAN

button will not work when the IN1776QZX is in ZOOM mode

FLICKER / SHARPNESS Button
The flicker filter has seven positions. Each time the

FLICKER / SHARPNESS

button is pressed the unit cycles to the next flicker filter and eventually returns to the

original flicker setting. Perceived flicker varies according to the type of image displayed, the
signal’s vertical refresh rate, the display device brightness, the ambient room light, distance from
the screen, and even the individual viewer’s eyes. Press the

FLICKER

button several times to

step through the various settings, selecting the best one for each type of material.

You will notice that there is an inverse relation between flicker control and sharpness. The most
flickery settings have the sharpest image while the most flicker-free position offers the softest
picture. Three of the seven steps are described below:

Flicker Filter OFF - (Most Flicker / Greatest Sharpness) On multimedia shows and other
screens made up primarily of large text you may wish to defeat the flicker filter for maximum
sharpness.
