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 outstanding image quality through a streamlined  
development process.  
If the Portrait Accelerator option is installed, 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® allows radiologists or QA administrators to calibrate their  
viewing stations or adjust the panel’s curve to DICOM standards  
without administrator intervention.  
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.

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 (ALC)  
When enabled, the ALC system automatically adapts the display light  
output, depending on the ambient light in the room. The ambient light  
is measured by the ALC optical sensor located at the front of the  
display.

4. ADVANCED FUNCTIONS  
4.1. About this chapter  
Important  
The functions described in this chapter are intended for trained service  
staff only!  
Improper use of these functions may disorder the display. BARCO  
cannot be held responsible for the results or damage caused by  
improper use of these functions.  
This chapter describes only the Advanced functions in the OSD  
menus. For a description of the other functions (standard functions),  
please refer to the previous chapter, Operation .  
In this chapter, we assume the advanced user knows how to use the  
OSD system: How to browse through the menus, how to enter menus  
and sub-menus, how to select and change values.  
These actions are described in the previous chapter.  
About the Advanced functions  
The advanced functions are extensions of the OSD menus. A standard  
user browsing through the OSD system sees only the standard

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.

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 Standard 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 Standard  
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  
settings.

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 Tilt the panel.  
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 panel.  
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.

TROUBLESHOOT-  
ING  
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 informa-  
tion.  
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 ex-  
changing the unit.  
Please contact our Customer Service Department if the number of  
pixel faults exceeds the above-mentioned figure.
