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-inbacklight 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’spatent-pending,built-incalibration device, continuously maintaining image quality. WithI-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.

User manual MFGD 2320

Best resolution

The optimum and recommended resolution is 1600 x 1200 or1200 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-screenmenus.

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.

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 RGBsub-pixelsof the panel equally.

Use this setting in case the imaging board is a color board.

RGB->RGB .............The R video signal drives the Rsub-pixels,the G video signal drives the Gsub-pixelsand the B video signal drives the Bsub-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.

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-cleaningproduct 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-freeas possible. This is to avoid more dust entering the display when opening it.

To remove the glass panel:

1Switch off the display.

2Tilt the panel.

3Unscrew the 4 sunken screws at the rear, fixing the glass panel and bezel.

4Unplug the cable plugged in on the bezel.

5Remove 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-guardlight sensor on the LCD panel.

6. 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 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-mentionedfigure.
