1.OVERVIEW

1.1. Introduction

The MFGD 2320, BARCO’s 20” 2 megapixel grayscale 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 out standing image quality through a streamlined
development process.

If the Portrait Accelerator option is inst alled, 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 panel can be adjusted by means of a control wheel on the display.

I-Guard

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
viewing stations or adjust the panel’s curve to DICOM standards
without administrator intervention.

®

allows radiologists or QA administrators to calibrate their

Autoset feature

The display has an Autoset feature that helps the user to adjust
standard scans: With one single function, you can automatically adjust
the display completely .

Autoscan

When you connect a video signal, the display checks in the internal
memory if the signal has been adjusted before. If so, it selects the
settings and parameters that match the connected signal.

When you connect a video signal that hasn’t been connected before,
and adjust the display to the signal, the adjustments and signal timing
parameters are stored in a programmable scan mode.

User manual MFGD 2320 4

Best resolution

The optimum and recommended resolution is 1600 x 1200 or 1200 x
1600 (if the Portrait Accelerator option is installed).

The recommended refresh rate is 60 Hz.
Would you have trouble selecting a proper display setting in

Windows, please refer to the Troubleshooting section further.

BARCO’s BarcoMed 2MP2FH imaging board is the best choice to
drive the MFGD 2320 display.

Power saving (DPMS)

The MFGD 2320 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. The power saving system can be
switched on or off using the on-screen menus.
This system requires a computer imaging board that supports power
saving management.

Ambient Light Compensation

Ambient Light Compensation is sometimes abbreviated to ALC. See
Introduction.

The Ambient Light Compensation menu contains the following items:

Min ALC .................. Contains two functions to set the minimum point

of the ALC control system:

- Measure Min Ambient Light: Decrease the
light in the room to the minimum possible
level you are likely to work in. Next, execute
this function.

- Min Luminance: Adjust this value until the
luminance is at the level you wish to work
with when the ambient light is at the minimum
level you have set in the above function.

Max ALC ................. Contains two functions to set the maximum point

of the ALC control system:

- Measure Max Ambient Light: Decrease the

light in the room to the maximum possible level
you are likely to work in. Next, execute this
function.

- Max Luminance: Adjust this value until the

luminance is at the level you wish to work with
when the ambient light is at the maximum level
you have set in the above function.

Low Pass Filter*

* Not in DVI mode

The display electronics provide 4 different low-pass filters to filter
possible high-frequent distortion from an analog video signal.

Select a different filter in case the image contains high-frequent noise
or distortion. Select the filter that gives the best result.

Readjustment of sample phase is necessary after selection of a
different filter .

User manual MFGD 2320 26

4.3. Advanced functions in the Settings menu

The Settings menu contains the following advanced functions:

Lookup Table

The display contains a number of factory-defined and user-defined
Lookup Tables (LUTs).

Turn the control wheel to select a LUT.

- Select a DICOM lookup table for most medical viewing
applications. The DICOM function results in more visible grayscales
in the images.

- Select a CRT (gamma) lookup table in case the display is used to
replace a CRT display.

- LUT 3 and LUT 4 are user-programmable lookup tables (dedicated
software needed).

- If you select None, no LUT will be selected.

- The selection Test LUT is meant for internal test purposes. It
should not be selected for normal operation.

Input Mode

To change the Input Mode setting, click the control wheel. Turn the
wheel to select St andard or Extended input mode. Then click the wheel
again to enter the selected submenu.

The following input mode settings can be selected:

Standard input mode

RGB->Y................... The RGB video signals from the imaging board

are calculated and transformed into a single
luminance value according to the formula

0.3R + 0.59G + 0.11B. This single luminance
signal drives the RGB sub-pixels of the panel
equally.
Use this setting in case the imaging board is a
color board.

RGB->RGB ............. The R video signal drives the R sub-pixels, the G

video signal drives the G sub-pixels and the B
video signal drives the B sub-pixels. This is the
preferred setting for grayscale imaging boards
that have the luminance signal on all 3 video
channels, because it ensures the most levels of
gray.

User manual MFGD 2320 27

G->Y........................ The Green video signal from the imaging board

is used as luminance value to drive the RGB
subpixels of the panel equally .

B->Y ........................ The Blue video signal from the imaging board is

used as luminance value to drive the RGB
subpixels of the panel equally .

R->Y........................ The Red video signal from the imaging board is

used as luminance value to drive the RGB
subpixels of the panel equally .

Note: The LCD panel used in this display is originally an RGB panel, of
which the colors are disabled. All RGB subpixels are used for
grayscale reproduction.

Extended input mode

The submenu Extended contains all the items from the S tandard
submenu, plus the following possibilities:

GRB->Y................... The RGB video signals from the imaging board

are calculated and transformed into a single
luminance value according to the formula

0.3G + 0.59R + 0.11B. This single luminance
signal drives the RGB sub-pixels of the panel
equally.

GBR->Y................... The RGB video signals from the imaging board

are calculated and transformed into a single
luminance value according to the formula

0.3G + 0.59B + 0.11R. This single luminance
signal drives the RGB sub-pixels of the panel
equally.

BRG->Y................... The RGB video signals from the imaging board

are calculated and transformed into a single
luminance value according to the formula

0.3B + 0.59R + 0.11G. This single luminance
signal drives the RGB sub-pixels of the panel
equally.

BGR->Y................... The RGB video signals from the imaging board

are calculated and transformed into a single
luminance value according to the formula

0.3B + 0.59G + 0.11R. This single luminance
signal drives the RGB sub-pixels of the panel
equally.

OSD position

With the OSD function you can select where on the screen the OSD
menu text will appear. You can select between center position, top left,
top right, bottom left or bottom right.

4.4. Advanced functions in the Scan Mode menu

The Scan Mode menu contains the following advanced functions:

Autoscan

Click the control wheel to switch the Autoscan system on/off.
We recommend, however, to leave the Autoscan function on. When

on, the display automatically looks if the connected video signal
matches a scanning mode from the predefined table of scanning
modes. When switched off, you can select a scanning mode manually.
However, the settings stored in the predefined table for the manually
selected scan mode, may not be suited at all for the connected video
signal. In that case the result will be a distorted image.

For more information, see also § "Controlling the display" in the
previous chapter.

Reset All

Click the control wheel if you wish to reset all the settings of all scan
modes. In the menu that appears next, click on Proceed to reset the

5. 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 suited for coated glass surfaces.

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

User manual MFGD 2320 30

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 avoid more dust entering the display when opening
it.

To remove the glass panel:

1 Switch off the display.
2 T ilt the p anel.
3 Unscrew the 4 sunken screws at the rear, fixing

the glass panel and bezel.
4 Unplug the cable plugged in on the bezel.
5 Remove the bezel with glass p anel.

Cleaning instructions:

- Dust, fingerprints, grease etc. can be removed by using a soft
damp cloth (a small amount of mild 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.

6. TROUBLESHOOT­ING

Windows does not show the desired display settings

Should you have problems selecting display settings for portrait
oriented displays in the Windows Display Properties control panel,
disable the option Hide modes that this monitor cannot display in
the control panel (see below).

User manual MFGD 2320 31

Information:

The display contains a special memory chip that contains information
about the display's scanning capabilities. When Windows starts up, it
reads the contents from this memory and presents a number of display
settings in the Display Properties control panel, based on this informa­tion.

The memory of this display contains the information the display can
handle scanning systems up to 120 Hz. That is why Windows will
propose a display setting with a high refresh rate. However, it is best

to select a refresh rate of 60 Hz.

The information that the display can be used in portrait mode, is also
stored in the display memory. However, Windows does not recognize
this and presents only default landscape modes if the option Hide
modes that this monitor cannot display in the control panel is
enabled.

Pixel Faults

Permanently dark or bright pixels can happen to TFT displays. 10 or
less permanently dead pixels do not make out a good case for ex­changing the unit.

Please contact our Customer Service Department if the number of
pixel faults exceeds the above-mentioned figure.
