OVER VIEW

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 ® 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.

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

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 preset.

Using the Autoset* functions

* Not in DVI mode

The Autoset menu provides a set of functions to adjust the display automatically.

It is necessary to perform the Auto Gain and Auto Phase calibrations in the following cases:

• The first time you use the display on an analog video

• After connecting or selecting another analog video source

It is necessary to perform the Automatic Geometry function in case you notice the image geometry or positioning is not as desired.

To obtain good results with the autoset functions, it is necessary to have a good image on which to perform the functions.

For Auto Geometry, the pattern should be an image that is filled up to the edges, from left to right and top to bottom. The edges of the image should have an intensity of at least 15% video amplitude. E.g., a

Windows desktop pattern would be a good image.

For Auto Phase, the pattern should contain sharp black-white transitions, like a line pattern or characters.

For Auto Gain, the pattern should contain parts that are completely black (0% video amplitude) and parts that are full white (100% video amplitude).

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.

The advanced functions are extensions of the OSD menus. A standard user browsing through the OSD system sees only the standard functions. When logged in in advanced mode, the user sees the standard and advanced functions in the OSD menus.

1 Enter the main menu.

2 Turn the control wheel to select the menu item EXIT.

3 Click and hold the control wheel for a few seconds until the OSD main menu is refreshed on the screen.

You have now logged in as advanced user.


Advanced functions in the Adjustment

In Advanced mode, the Geometry menu additionally contains the following functions:

Hor Active ................ Allows you to change the horizontal size of the active video window around the image, expressed in pixels. If you decrease this size, you may blank a part of the image.

Vert Active ............... Allows you to change the vertical size of the active video window around the image, expressed in pixels. If you decrease this size, you may blank a part of the image.

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.


* Not in DVI mode

The display electronics provide 4 different low-pass filters to filter

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.

Advanced functions in the Settings menu

The Settings menu contains the following advanced functions:

The display contains a number of factory-defined and user-defined

Display functions (LUTs).

Turn the control wheel to select a display function.

applications. The DICOM function results in more visible grayscales in the images.

to replace a CRT display.

- LUT 3 and LUT 4 are user-programmable display functions

(dedicated software needed).

T est LUT should not be selected for normal operation.

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:

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.

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.

of which the colors are disabled. All RGB subpixels are used for grayscale reproduction.

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.

RBG->Y ................... The RGB video signals from the imaging board are calculated and transformed into a single luminance value according to the formula

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

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.

The Preset menu contains the following advanced functions:

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

MAINTENANCE

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.

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.

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.

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.

- 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.

TROUBLESHOOTING

W indows does not show the desired display

Should you have problems selecting display settings for portrait oriented displays in the Windows Display Properties control panel, the control panel (see below).

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

However , it is best

The information that the display can be used in portrait mode, is also stored in the display memory. However, Windows does not recognize enabled.

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.
