1. INTRODUCTION

1.1 Overview

Resolution and bandwidths

The BARCO MGD 521 M and MGD 521 MKII displays are ultra-high
resolution, grayscale portrait displays. Their outstanding visual
performance, combining a 5 MegaPixel resolution with a very high
brightness, makes them ideal for diagnostic imaging and many other
medical and scientific applications.

The displays are compatible with any AC power system worldwide
and automatically synchronise to a wide range of sync frequencies.
their high-speed video amplifiers support pixel clocks up to 500 MHz
(MGD 521 M: 550 MHz).

The memory system

The internal memory system can contain the adjustments for 16
different scanning formats, the so-called scanning modes. Each
scanning format is characterized by its sync signals. The displays
internal micro controller continuously samples the connected sync
signals and compares them to the scanning modes already stored in
the memory. If the connected signal has already been stored, the
micro controller adapts the image to the corresponding adjustment
values in the memory, and further adjustments are unnecessary.

Image conformity and consistency

Image conformity and consistency are the keywords. In our factory,
the MGD 521 displays are perfectly adjusted and calibrated before
they are shipped to the customer. Internal circuits, like the TrueGrey®
and Automatic White Stability (AWS) systems, ensure display
consistency over time.

Conformity with the original image quality is guaranteed by the
automatic calibration, which can be done by means of an optical
sensor, connected to the Sensor connector on the display. The
sensor is not supplied with the display.

Calibration and adjustments

The conformity calibration, as well as the complete adjustment of the
display, can be performed by means of the remote, user-friendly
MediCal® software package. MediCal is especially developed to

Introduction 9

adjust and check BARCOs medical displays.
A lot of adjustments can also be done on the monitor itself, by means

of an extensive on-screen menu system, accessible from the rear
panel controls.

Power saving system

The MGD 521 displays are equipped with a power saving system.
When left idle for a certain time, the computer, connected to the
display, will power down the display in several steps. The power
saving system can be switched on or off during the installation or
adjustment of the display.
This system requires a computer imaging board that supports power
saving management.

P45 phosphors ................ x .................................. x

P104 phosphors ....................................................x

50 Ohm input .................. x .................................. x

75 Ohm input .................. x .................................. x

Notes:

- The P45 phosphors produce rather bluish images, whereas the

P104 phosphors produce more yellowish images.

- A video input terminated to 50 Ohm requires an imaging board

with an impedance of 50 Ohm. A video input terminated to 75 Ohm
requires an imaging board with an impedance of 75 Ohm.

- The type of CRT phosphors and the video input termination are

indicated on the label at the rear of the display.

Important:
It is absolutely necessary that the impedances of imaging board and

display are the same. If not, the image quality will be inferior.

The MediCal software and the X-Rite DTP92 sensor are not delivered
with the display.

MediCal can be ordered separately.

1.3 About the manuals

This guide is meant for people who want to install and use the MGD
521 displays, as well as people who need to install and adjust the
displays. Chapter 4, Adjustments, is meant for this second category
only, because it describes actions and procedures that require a
technical skill to be performed properly.

The use of the software MediCal is described in the MediCal Users
Manual.

2. INSTALLATION

2.1 Precautions

 Keep your original packaging. It is designed for this display and is

the ideal protection during transport.
 Do not lift the display all by yourself to avoid injury.
 Avoid reflections in the picture tube to reduce eye strain.
 Place the display on a strong and stable table or desk if used as

desktop display.
 Keep the display away from heat sources and provide enough

ventilation in case it is built in a rack or console.
 Keep the display away from strong sources of magnetic fields.
 Make sure the display and computer are both switched off before

connecting the signals.

2.2 The package contents

 The display
 The accessory box (in which you found this manual)

Notes:
 The display can be part of a complete MeDis

of the display itself, an imaging board and software. In that case,

the package contains a lot more items. The contents of the

package is then described in the manual of the complete system.
 The ambient light shield inside the accessory box should always

be used during conformity calibration with the X-Rite DTP92

optical sensor.
