1. OVERVIEW

1.1 Introduction

I-Guard

The MFGD 3220D, BARCO’s 21” 3 megapixel
greyscale LCD display , guarantees perfect image
quality in medical imaging applications.

The display combines a TFT (thin film transistor)
liquid crystal display panel structure and a built-in
backlight with inverter for a better picture quality . It
is designed to meet the users' needs for
performance, consistency, and outstanding image
quality through a streamlined development
process.

The display can be used in portrait or landscape
version, simply by turning the panel. The tilt &
swivel foot allows ideal positioning of the panel, in
height and viewing angle.

The image brightness can be adjusted by means
of a control wheel on the display . Other image
parameters can be adjusted by means of external
software, like MediCal® Pro.

I-GUARD® is Barco’s patent-pending, built-in
calibration device, continuously maintaining image
quality. With I-GUARD®, QA checks no longer
need to disturb normal radiology activities, as they
can be performed while applications are running.

I-GUARD® allows radiologists or QA
administrators to calibrate their viewing stations or
adjust the panel’s curve to DICOM standards
without administrator intervention.

MediCal Pro

Multi-scan capabilities

In combination with Barco’s MediCal ® Pro
management and calibration software package,
Coronis offers a truly intervention-free display
system, making it possible to perform QA checks
from one central server at any time, thereby
reducing lifecycle cost.

The optimum and recommended resolution is
2048 x 1536 or 1536 x 2048 at 60 Hz.

The MFGD 3220D display will also display most
of the computer boot modes.

BARCO's BarcoMed 3MP2FH imaging board is
the best choice to drive the MFGD 3220D display.

external power supply block. Also, do not

turn the power supply upside down or at its

side. Doing so would cause overheating of

the power supply .

2.2. Before installing the display

Important:

In the factory , the height-positioning system in the
display foot is blocked with a strap to prevent
damage during transportation.

Before installing the display, you must remove this
strap.

T o remove the strap:

1 Position the display with its rear side facing

you.
2 If the foot cover is mounted on the foot, lift

up the 2 clips of the foot cover to release the

cover from the foot.
3 Pull the lower side of the cover towards you

and simultaneously slide the cover

downward.

MFGD 3220D User's Guide 10

4 Pull the red strap out of the fixation holes in

the foot.

You can better leave the cover off the foot while
connecting the signal cables to the display.

2.3 Portrait or landscape position

You can change the orientation of the panel at any
time, but it is more convenient to select
landscape or portrait orientation before
connecting the cables.

To change the panel orientation:
1 Stand at the front side of the p anel and t ake

the panel at both sides.

2 Very import ant: Tilt the panel before

changing the orientation.
Should you change the panel orientation
without tilting it first, you might irreversibly
damage the tilt & swivel mechanism.

3 To change from portrait to landscape, turn

the panel counterclockwise while lif ting it
up slightly.
To change from landscape to portrait, turn
clockwise.

2.4 Connecting the signals

To get access to the connectors, open the cover
of the connector compartment by pulling down the
2 clips of the cover.

To connect the video & sync signals:

1 Connect one end of the video cable to the

DVI input (5) of the display.

2 Connect the other end of the video cable to

the video output of your video source
(Computer graphics board with digital video
output).

3 Route the cable so that it enters the

connector compartment at the place where
the cover is bulged.

Example of signal connection in a Coronis dual­head system

To connect the power:

1 Connect the output of the 12V DC power

supply to the DC input (6) of the display .

2 Connect one end of the proper power

cable to the AC input of the 12V DC power
supply.

MFGD 3220D User's Guide 12

3 Connect the other end of the power cord to

a grounded power outlet.

2.5. Routing the signal cables

After connecting all cables, fix them in the cable
tie at the rear of the connector compartment. You
can also bind the cables together by means of the
2 velcro strips included in the package.

After fixing the cables, put the connector
compartment cover back in place. Pay attention
that the signal cables are positioned under the
bulge in the cover.

Next, fix the cables in the plastic clamps on the
foot. At last, put the foot cover back in place.

To put the foot cover in place:
1 Push the upper side of the cover onto the

foot, so that the hooks on the cover are
positioned right under the holes in the foot.

2 Slide the cover upward while moving the

lower side of the cover towards the foot.

3 Press the cover to the foot so that both clips

make a clicking sound.

2.6 Tilt and swivel positioning

Adjust the position of the panel for best viewing
conditions.

The display foot allows adjusting the panel height,
horizontal viewing angle and vertical viewing
angle.

2.7 Starting up

Proceed as follows:

1 Switch on the computer.
2 If necessary, select a suit able resolution in

the computer operating system. You will
have to select a resolution that corresponds
to the panel orientation (landscape or
portrait).

Please refer to the possible resolutions in
the Technical specifications.

Note: The recommended resolution for best
image quality is 2048 x 1536 or 1536 x

2048.

3. CONTROLS

The control wheel (2) at the bottom (landscape
orientation) or at the side (portrait orientation)
allows you to perform some controls. You can
switch the display in stand-by and control the
brightness.

3.1 Stand-by switching

When the display is on, depress the control wheel
slightly to switch the display in stand-by.

When the display is in stand-by, depress the
control wheel slightly to turn it back on.

3.2 Brightness control

Turn the control wheel (2) clockwise to increase
the brightness.

Turn the control wheel (2) counterclockwise to
decrease the brightness.

The Brightness control can be disabled using the
MediCal Pro software.

4. MAINTENANCE

Panel

Take care not to damage or scratch the panel. Clean
with a soft woolen or cotton towel. Use a watery
solution or a mild commercial glass cleaning product.

Cabinet

Do not use chemical cleaning products, benzene,
toluene, xylene or other solvents. Clean with a soft
cloth dampened with mild detergent and water.
Repeat with water only and wipe dry with a dry cloth.

Removing dust from the rear of the glass panel

It may be possible that dust particles have entered
the display and are stuck to the rear of the glass.

We recommend to let this cleaning procedure be
done in a BARCO service center.

However, when really necessary, you can perform the
cleaning on site if you can work in conditions that
are as clean and dust-free as possible. This is to

Tilt the panel

avoid more dust entering the display when opening it.

Remove the sunken screws

To remove the glass panel:

1 Switch off the display .
2 Tilt the panel.
3 Unscrew the 4 sunken screws at the rear, fixing

the glass panel and bezel.

4 Remove the bezel with glass panel.

Cleaning instructions:

- Dust, fingerprints, grease etc. can be removed by
using a soft damp cloth (a
detergent can be used on the cloth, NOT solvent).

- Do not apply liquid directly to the LCD surface as
excess liquid may cause damage to internal
electronics.

- Take care not to touch the I-guard light sensor on
the LCD panel.

Pixel Faults

Permanently dark or bright pixels can happen to
TFT displays. 20 or less permanently dead pixels
do not make out a good case for exchanging the
unit.

Please contact our Customer Service Department
