Jumper location

There is one user changeable jumper on the BarcoMed Coronis. It is
used to enable or disable the VGA capabilities of the display controller.

31

BARCOMED CORONIS display controller installation

Figure 4: VGA Jumper Enlarged View

Using the VGA capabilities of the BarcoMed Coronis

Prior to installing the BarcoMed Coronis, decide if you are going to use
its on-board VGA capabilities. If you are, check the setting of the Jumper
at J-1 on the display controller (see figure 4 VGA Jumper Enlarged View).
By default, VGA should be enabled, on the top two pins.

NOTE: To use multiple BarcoMed Coronis display controllers in a
single host with VGA enabled, you need to enable VGA on only
ONE of the BarcoMed Coronis display controllers and disable VGA
on ALL other BarcoMed display controllers.

Examples of PCI slots

Although the BARCOMED CORONIS controller is a 64-bit board, it may be
installed in either a 64-bit or 32-bit PCI slot. However, installing it in a
32-bit PCI slot will result in a decrease in performance. Figure 5
illustrates the types of slots so that you can correctly identify which one
to use for the BarcoMed Coronis.

32

BARCOMED CORONIS display controller installation

Figure 5: PCI and RAID Controller Slots

Install the BarcoMed Coronis controller in your computer
following these steps:

1. Turn off the power to your computer and disconnect the power

cord, however make sure that the computer chassis is still
grounded.

2. Remove the chassis cover according to the manufacturer’s

instructions. Be sure to observe safety warnings.

3. If you have decided to use the on-board VGA capabilities of the

BarcoMed Coronis (see Using the VGA capabilities of the
BarcoMed Coronis on page 32), you must now remove any VGA

display controller(s) that are currently installed in the computer or
disable any VGA controllers that are integrated into your PC’s
motherboard.

4. Install the BarcoMed Coronis Controller into a free PCI slot, either

64-bit or 32-bit (see figure 5, for examples of slots). Be sure that
the display controller is seated firmly in the slot.

5. Secure the card to the chassis with the PC’s I/O panel mounting

screw, and replace the chassis cover.

6. Connect the primary display (left most display in a linear

configuration, top most in a vertical configuration) to the
uppermost connector on the BarcoMed Coronis (the output farthest
from the motherboard – “Head 1” in figure 6) using the provided

33

BARCOMED CORONIS display controller installation

DVI cable. For a dual-headed BarcoMed Coronis setup, connect the
secondary display to the other connector on the display controller.

7. Replace the chassis cover, reconnect the power cord, turn on the

power, and boot the system as usual.

Running multiple BarcoMed Coronis display controllers in a single host

The physical order of the displays may vary when you are running
multiple
bus control in the system BIOS, and not the BarcoMed display controller.
It may become necessary, depending on how your PC’s BIOS configures
the PCI bus, to switch your DVI display connections to achieve a linear
desktop configuration.

BarcoMed PCI Express® Controllers

During the first quarter of 2006 Barco Medical Imaging Systems added
PCI Express (PCIe) versions of its Coronis and Coronis 5MP display
controllers to its grayscale Medical Imaging Display Systems product
line. The PCIe versions of these boards will have the same features as
the currently shipping PCI version.

All three PCIe boards will feature a x8 logical bus on a x8 physical
connector. They have been designed to function in PCI Express x8 or x16
slots. Optimum performance will always be obtained by installing them
in a PCIe x8 slot. Depending on your PC manufacturer’s implementation
of the logic for the PCIe x16 slot optimum performance may also be
obtained by installing the Barco PCIe boards in the PCIe x16 slot.

Connecting your Barco displays to your BarcoMed PCIe board is identical
to connecting them to a BarcoMed PCI board (please refer to your
system manual for details).

Notice:

If, after installing the display or the system, you change the panel
orientation while an image is on the screen, the result depends on your
application:

42

After unpacking the display

• In a Coronis system, the image orientation will adapt to the new
panel orientation automatically after a second.

• If the I-switch software is installed and enabled, the image
resolution will also be adapted automatically to the new panel
orientation.

• If you use the display stand-alone, the image orientation will
not change with the panel orientation.

Only the orientation of the on-screen display (OSD) will change
automatically in case “Orientation” in the OSD Geometry menu is
set to “Automatic”.

To change the orientation of the image, you will have to change
the resolution in the Windows Display control panel (if possible).

Avoiding image retention

Avoiding image retention

Image retention (image sticking, ghost image) is the phenomenon
where an image, or a part of it, seems to be ‘burnt’ in the LCD panel.

When you display e.g. a uniform light gray image you distinguish the
ghost image in the background.

This phenomenon occurs on all types of LCD panels when a static image
remains on the screen for a long time (unfortunately the exact period is
not predictable). Also parts of the image that do not change often (e.g.,
toolbars, buttons, borders) are susceptible to image retention.

Image retention may be undone in some cases, but it may also damage
the LCD panel permanently. So it is better to take precautions during
product installation to avoid it.

Here are some countermeasures you can take:

Power off, power save mode, screen saver

Very important is to use screen savers and power saving modes as
much as possible. If you do not need the display for a few hours, switch
it off. If you only need to look at it when you actually do something on
the screen, use a screen saver.

The amount of “relaxation” time should be considerable, the more you
do it the better. “Flashing” the screen for a few seconds with a screen
saver is not sufficient. Image retention is a slow process to build up, but
it also disappears slowly.

Re-Layout

In most applications, a display is used to show a layout of several
components with borders. Whereas the content in these windows can
change continuously, the borders are static images and may cause
boundary image retention. The layout of the windows (size, number of
windows, etc.) should be changed as much as possible.

60

Avoiding image retention

To activate appropriate screen saving, proceed as follows:

1. In the display OSD menus, open the Settings menu and switch

DPMS on. For more information, please consult the display

operation chapter.

2. In Windows, open the Display control panel. Open the Screen

Saver tab.

3. Select a screen saver from the Screen saver drop-down box.

4. Set the Wait time to 10 minutes.

5. Click the button Power... The Power Options Properties dialog

opens.

6. In the Turn off monitor drop-down box, select After 20 mins.

7. Click Apply.

8. Close the control panel.

BarcoMed control panel operation

This chapter describes how to configure the displays in your Barco
Medical Imaging Display System using the tools available through the

Advanced button on the Settings tab of the Windows Display Control
Panel.

Accessing the Barco tab

Note: You must have logged on to Windows using an account with

administrator privileges in order to use the Barco portions of the
“Windows Display Control Panel” to change any display settings.

1. Open the “Windows Display Control Panel” by one of the two

methods below:

a) Start > Settings > Control Panel > Display

or

b) Open the “Display Properties Control Panel” by right clicking

in an empty area on the desktop, then select “Properties”.

2. Click on the “Settings” tab.

3. Select the “rectangle” that represents the Barco display whose

settings you wish to change.

4. Click on the “Advanced” button.

5. Select the “Barco” tab from the Properties screen.

Using the Barco tab

The Barco tab is divided into three sections. The first section provides
information about the graphics controller and allows access to the
graphics controller advanced configuration pages. The second section
provides information about the display. The bottom section allows
access to two Barco tools, Barco System Report and Barco’s softcopy QA
solution, MediCal QAWeb, MediCal Pro or Niowatch, depending on which
solution is installed on your system. Also, there is a active link to the
Barco Medical Imaging web site.

Advanced Properties

To access the advanced properties configuration pages for your Barco
display controller(s), click on the Advanced button in the Graphics
Device Information section.

BarcoMed advanced configuration

There are two pages accessible from the advanced configuration button.
They are:

• Barco Drawing Modes

• Device Details

These two pages replace the following three pages found in earlier
versions of the BarcoMed display controller drivers.

• the BarcoMed Driver Tab,

• the BarcoMed Hardware Tab, and

• the BarcoMed Display Tab.

Barco Drawing Modes

The Barco Drawing Modes page of the Advanced Properties page is
divided into four sections: Palette Mode, Drawing Modes, Monitor
Configuration, Graphics Board.

Palette Mode

In the Palette Mode section you can choose one of the four following
Palette Modes. If you are using a color display in conjunction with your
Barco grayscale display(s), prior to selecting a palette mode please
make certain that you have configured your Windows desktop correctly.
(See the section Setting the resolution of your C
page 102.)

ORONIS display on

Color to Gray Compatibility

Use this palette option for applications, such as Java, which require True
Color support. Such applications may not work correctly when using one
of Barco's three “Standard 8-bit (256-color)” palette modes. All

67

BarcoMed control panel operation

applications that are designed to work correctly with 8-bit (256-color)
modes should continue to work normally.

Note: Ditherng is not used while in this mode. Also, direct access to the

hardware through DirectDraw is not allowed in this mode.

User Modifiable Color Palette

This option allows applications to modify the palette contents
dynamically. This mode reserves the first 10 and last 10 entries in the
palette for the Windows operating system, but applications can
manipulate the middle 236 entries. This is the standard palette mode as
configured by Windows.

Static Gray Palette including standard system colors

This option sets the palette to be a static linear set of 236 gray values.
The 20 standard system colors are converted from RGB to gray values
and are added to the 236 static gray values. Applications are denied the
ability to dynamically change or allocate palette entries.

Static Gray Palette with NO system colors

This option sets the palette to be a static linear ramp of 256 shades of
gray. Applications are denied the ability to dynamically change or
allocate palette entries.

Drawing Modes

In the Drawing Mode section you can choose from the following
Drawing Modes. If any of the options in this section are grayed out, then
they are not available for the model controller with which you are
working.

Enable DirectDraw

This option allows the user to enable or disable DirectDraw. DirectDraw
is a software interface that provides direct access to display devices

68

BarcoMed control panel operation

while maintaining compatibility with the Windows graphics device
interface (GDI). DirectDraw is enabled by default.

More information about DirectDraw is available through the on-line
help.

Enable Dithering

This option allows the user to enable or disable dithering. Dithering is a
technique for increasing the perceived range of colors in an image at
the cost of spatial resolution.

Note: This option is only available when the User Modifiable Palette

mode is selected. If either the Static Gray Palette including Standard
System Colors mode or the Static Gray Palette with NO System colors
mode is selected, the “Enable Dithering” check box will be grayed-out,
and dithering will be automatically disabled.

More information about Dithering is available through the on-line help.

Disable 10-bit grayscale

Use this option for standard Windows®-based applications that require
8-bit color support (256 colors), such as Internet Explorer, Excel, etc.

Do not use this option for applications that require 10-bit pixel support
(1024 simultaneous shades of gray) and use extended depth graphic
libraries such as WinBarco.

Description of 10-bit grayscale

To show 1024 simultaneous shades of gray all BarcoMed “H” series
display controllers, such as the BarcoMed 5MP2FH or BarcoMed Coronis
or example, run in extended depth (10-bit) mode by default.

Implications

When turned on the “Disable 10-bit grayscale” option causes a
BarcoMed Coronis display controller to run in 8-bit mode, which results
in increased performance since the frame buffer is set to run with 8-bit
pixels. While this option may be used with applications that normally
require 10-bit support, there will be a loss of pixel depth, i.e. 256
shades of gray instead of 1024 simultaneous shades of gray.

69

BarcoMed control panel operation

Disable RGB To Static Gray Color Translation

Select Disable RGB To Static Gray Color Translation if you wish to have
RGB values equally weighted, with 1/3 each. When not selected, then
the International Commission on Illumination (CIE – Commission
Internationale de I’Eclairage) model will be adapted, which weights the
colors as 59% Green, 30% Red, 11% Blue.

Monitor Configuration

If the options in this section are grayed out, then they are not available
for the model controller with which you are working.

Graphics Board

There is one option in this section, the Update Firmware button. Clicking
this button will launch the BarcoMed Hardware Configuration utility.
This program allows the user to flash update the firmware stored in the
ROM of the currently selected BarcoMed display controller. The
BarcoMed Hardware Configuration utility is implemented in a Wizard
format, which guides the user through the flash update procedure. The
user will be prompted to select a firmware update file to use for the
update process. This file will be provided by Barco Medical Imaging if
and when a firmware update is required.

Device details

The Device Details page provides detailed information about the display
controller connected to the active display. This information is useful in
debugging issues that may occur when using your Barco Medical
Imaging Display System.

Operating precautions

Continuous operation of the display with the same image may result in
some image sticking on the LCD panel. Over 10 hours operation with the
same image content is not recommended.

Switching on DPMS on display and PC and activating a good screen saver
may decrease the risk of image sticking (image retention).

Stand-by switching

It may be possible that dust particles have entered the display and are
stuck behind the front glass.

We recommend to let this cleaning procedure be done in a BARCO
service center. The product warranty expires when the user

removes the glass panel or otherwise opens the display.

However, when really necessary, you can perform the cleaning on site if
you can work in dust-free conditions. This is to avoid more dust entering
the display when opening it.

To remove the glass panel:

Figure 28

1. Switch off the display.

2. Tilt the panel.

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

and bezel (28).

4. Carefully take the glass panel a few centimeter from the display. It

is still connected to the rest of the display by means of the LED
connection.

5. Unplug the LED connection (29).

94

LCD panel

Figure 29

To clean the LCD panel:

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

• Dust particles on the LCD panel may be blown away by using a

dust remover. E.g., DUST OFF 67 (KONTAKT Chemie).

A dust remover is composed of a blend of compressed liquid gases
functioning as propellant. They provide a jet of dry inert gas that
acts like compressed air for a quick and safe removal of dust
particles and other dry contaminants on the surface of the lcd
panel or the glass panel.

Attention: The dust remover contains a liquid gas. If you shake the
can or move the can too fast while spraying, you may blow drops
of liquid on the panel surface!

If this is the case, clean the panel as described below.

• If the LCD panel is dirty or wet, clean the panel using a lint-free,

nonabrasive cloth, lightly moistened with a solution of 25%
Isopropyl Alcohol (IPA) and 75% de-ionized or distilled water.
E.g.: Cleareen, a product of Certified Laboratories.
In case you do not dispose of these products, use plain water
instead.

• Take another clean, dry, soft, lint-free cloth and gently wipe the

glass dry.
