equivalent, 18 AWG min.,
rated 300 V min., provided
with a hospital-grade type
plug 5-15P configuration for
120V application, or 6-15P
for 240V application.

• Warning: This apparatus
must be earthed!

• Power requirements:
connect the apparatus to an
AC voltage as indicated at
its back. Using a lower
voltage, the apparatus will
not be able to operate. Using
a higher voltage may
damage the apparatus.
If you are not sure of the type

of power supplied, consult
the power company.

• Do not overload wall outlets
and extension cords as this
may result in fire or electric
shock.

• Mains lead protection (U.S.:

INTRODUCTION

Overview

Resolution and
bandwidths

The memory system

Image conformity and
consistency

The BARCO MGD 2621 P is a high-resolution
greyscale portrait display. Its outstanding visual
performance, combining a 2 MegaPixel resolution
with a very high brightness, makes it ideal for
medical imaging and many other medical and
scientific applications.

The MGD 2621 P is compatible with any AC
power system worldwide and automatically
synchronises to a wide range of sync
frequencies. Its high-speed video amplifier
supports pixel clocks up to 250 MHz.

The internal memory system can contain the
adjustments for 4 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 are the
keywords. In our factory, the MGD 2621 P
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.

Introduction 5

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, which runs
under Microsoft Windows NT, is especially
developed to adjust and check BARCO’s medical
displays.

A lot of adjustments can also be done on the
monitor itself, by means of an extensive on­screen menu system, accessible from the rear
panel controls.

Power saving system

The MGD 2621 P is 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.

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.

About the manuals

This guide is meant for people who want to install
and use the MGD 2621 P display, as well as
people who need to install and adjust the display.
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.

Precautions

The package contents

• 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.

Unpacking the display

The display is packed in a box on a pallet.

To unpack:

1. Cut the ribbons around the box by means of a
pair of wire-cutters.

2. Lift the box from the pallet.
The display remains standing on the pallet.

3. Remove the Accessory box and the upper
polystyrene piece.

4. Remove the plastic bag from the display.

5. Lift the display out of the lower polystyrene
piece.

Power connection 1. Power cord: Utilise a UL-listed detachable

power cord, 3-wire, type SJ or equivalent, 18
AWG min., rated 300 V min., provided with a
hospital-grade type plug 5-15P configuration
for 120V application, or 6-15P for 240V
application.

2. Plug one end of the power cord into the rear of
the display (connector LINE {9}). Plug the
other end into a grounded AC power outlet.
The display automatically adapts to the
voltage. The voltage range is:
100-240 VAC +/- 10%.
