Advanced properties for MXRT controller
To access the advanced properties configuration pages for the display
controller(s) for your BARCO CORONIS 5MP MAMMO Display System, click
on the Advanced button in the Graphics Device Information section.
There are several pages accessible from the advanced configuration
button. They are:
• Barco Adapter Configuration
• OpenGL
• Direct3D
• Rotation (when supported)
• Details
• OpenGL Profiles
Barco Adapter Configuration
The Barco Adapter Configuration page allows you to switch between
the following monitor configurations and display options for the
displays connected to a Barco MXRT controller:
Display Layout
• DualView
Both displays are enabled independent of each other.
• SingleView
A single large desktop spans across both displays.
9
Graphic board control panel
• Clone
The primary display is cloned to the secondary display.
Color Format
• 24-Bit TrueColor Mode
• 30-Bit TrueColor Mode (HDR)
Display Resolution
• Sets display resolution for 1 or 2 displays.
Note: To switch out of SingleView or Clone mode, the
buttons in this Control Panel page must be used. The main
Windows Control Panel cannot be used. Depending on your
system, certain configurations can be disabled.
Note: Clone Mode is supported for two color displays or
projectors in 32bpp. Clone mode is not supported on grayscale
displays. Also, HDR is not supported while in Clone Mode.
When choosing Clone Mode under the Barco Adapter
Configuration page, if two displays are enabled, then the larger
of the two current resolutions will be used. If only one of the
two displays is enabled, the enabled displayís current resolution
will be used.
When the resolution set for clone mode is larger then the
maximum supported on a display, the resolution set on the
Master will automatically be scaled to maximum resolution of
the Cloned display. If the Scale to Display Preferred Mode is
checked, the maximum resolution will be the EDID preferred
mode. If it is unchecked, then it will be the largest mode in the
Cloned displays mode list. Clone mode can only be exited
through the Barco Adapter Configuration page in the Barco
Advanced Control Panel.
Note: Not all options are available at all times. Please select
the help tips in the driver software for more information.

Graphic board control panel
OpenGL and Direct3D
The OpenGL and Direct3D pages of the Advanced Properties page are
divided into two sections: Main Settings and Custom Settings.
Main Settings
In the Main Settings section there is a slider bar which allows the user
to adjust the OpenGL or Direct3D settings for optimum performance,
optimum quality or for a point in between. There is also a checkbox
provided for enabling Custom Settings.
Custom Settings
Note: Barco recommends that you use the default settings,
unless your viewing application vendor provides detailed
information on custom settings.
In the Custom Settings section the user can fine tune the following
options:
• Anisotropic filtering
• SMOOTHVISION
• Wait for Vertical Sync
Anisotropic Filtering
Anisotropic filtering is a technique that preserves detail on surfaces
that have three-dimensional perspective and fade away into the
background. It works best when used in conjunction with
Mipmapping.
Anisotropic filtering can be set to favor either an increase in system
processing performance or improved image quality.
Note: If you are unsure how to configure anisotropic filtering,
use the Application Preference option. Your display will
automatically adjust to the application’s requirements.
11
Graphic board control panel
Please refer to the on-line help (click on the “?” in the control panel’s
openGL tab) for more information on using advanced features such as
Anisotropic Filtering.
SMOOTHVISION
The Advanced Settings tab enables you to apply ATI’s SMOOTHVISION
technology for full-scene anti-aliasing. SMOOTHVISION improves
image quality by removing jagged edges (anti-aliasing) from 3D
images, resulting in smoother, more natural looking objects.
Please refer to the on-line help for more information on using
advanced features such as SMOOTHVISION.
Wait for Vertical Sync:
• For OpenGL the default setting is Default Off.
• For Direct3D the default setting is Application Preference.
Please refer to the on-line help for more information on using
advanced features such as Wait for Vertical Sync.
Rotation
The Rotation page is visible only when the display connected to the
current (active) head of your Barco MXRT display controller does not
support rotation internally. The Rotation feature allows the user to
rotate the Windows desktop to match the physical orientation of the
display.
(Device) Details
The 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 CORONIS 5MP
MAMMO Display(s).
12
Graphic board control panel
OpenGL Profiles
The Configuration page enables you to customize display profiles for
individual applications. Typically, you would change these settings for
one or more of the following reasons:
• Diagnostic purposes.
• Fine-tuning a specific application/system configuration.
• Specific settings recommended by your hardware or software
documentation.
• Tuning your application/system environment for best
performance and memory usage.
Activating a configuration profile
The Configuration Profiles list box displays a number of common
applications whose optimal configuration profile are factory-set by
default.
To activate a particular profile, select the application name from the
list and click Apply. This will add the information to the necessary
Windows registry settings. If prompted, restart Windows.
If you subsequently experience problems with your application, or if
you want to try to optimize the performance of your system on
specific applications, modify your configuration settings accordingly.
Adding a new application profile
Click the Add button in the Configuration Profiles section and enter
the name of the new application for which you want to set the
configuration parameters.
Modifying the configuration parameters
To change the configuration settings of a specific application, select
the name of that application from the Configuration Profiles list box.
Click the Modify button. Now select or clear the rest of the
13
Graphic board control panel
configuration controls on this tabbed dialog to obtain the desired
display parameters for the selected application.
To remove the selected configuration profile completely, select the
name of the application from the Configuration Profiles list box and
click Delete.

You cannot delete the factory-set configuration profiles.
Click the Apply or OK button to enable your Configuration settings.
Advanced Properties for BarcoMed Coronis or
BarcoMed Nio
Palette modes
From the Barco
palette modes.
Drawing Modes tab you can select one of four
• Color to Gray compatibility
• User Modifiable Color Palette
• Static Gray Palette including standard system colors
• Static Gray Palette with NO system colors
User Modifiable Color Palette
This option allows applications to modify the palette contents
dynamically. As indicated in figure 2, 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.
14
Graphic board control panel
Figure 2: User Modifiable Palette
Note: If you are unsure whether or not your application
requires this “User Modifiable Color” mode, contact your
application provider.
Static Gray Palette including standard system colors
This option sets the palette to be a static set of 256 gray values.
Applications are denied the ability to dynamically change or allocate
palette entries. This prevents palette conflicts between applications,
which can cause image color values to appear distorted in the
background application.
As shown in figure 3, the 20 standard system colors are converted
from RGB to gray values. The rest of the 236 entries from index 10 to
245 contain the missing gray values so that the palette has the full
256 gray values within it.
Figure 3: Static Gray Palette with system colors
Note: If you are unsure whether or not your application
requires this “Static Gray Palette with System colors” mode,
contact your application provider.
Static Gray Palette with NO system colors
This option sets the palette to be a static linear ramp of 256 shades of
gray. Therefore, applications are denied the ability to dynamically
change or allocate palette entries. This prevents palette conflicts
15
Graphic board control panel
between applications, which can cause image color values to appear
distorted in the background application.
As shown in figure 4, each of the 256 entries in the palette has an
RGB value of (i, i, i) where i is the index from 0 to 255.
Figure 4: Static Gray Palette with NO system colors
If you wish to use a static gray palette we recommend using the
“Static Gray Palette including Standard System Colors” option instead
of this one. This is due to the fact that some applications assume that
the first and last 10 entries of the palette are the standard system
colors. In this palette mode, these entries are made up from entries in
the bottom or the top of the gray ramp.
Note: If you are unsure whether or not your application
requires this “Static Gray Palette with NO System colors” mode,
contact your application provider.
More information about Palette Modes is available through the
on-line help.
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 while maintaining compatibility with the Windows
graphics device interface (GDI). DirectDraw is enabled by default.
16
Graphic board control panel
More information about DirectDraw is available through the online 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.
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, BarcoMed Coronis or BarcoMed
Coronis 5MP for example, run in extended depth (10-bit) mode
by default.
Implications: When turned on the “Disable Extended Depth”
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.
17
Graphic board control panel
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
The Monitor configuration page allows you to switch between the
following monitor configurations for the displays connected to a
BarcoMed controller:
• SingleView
A single large desktop spans across both displays.
• DualView
Both displays are enabled independent of each other.
Graphics Board
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 Systems if
and when a firmware update is required.
Device Details
From the Device Details tab you can access the Device Details page,
which 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 MDMG-5121(s).
18
Graphic board control panel
Configuring the Windows desktop
Note: If you are using a color display in conjunction with your
Barco grayscale display(s) you should configure your desktop
before setting the resolution of your Barco grayscale display(s).
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.
The recommended configuration for best grayscale image quality
when using a color display in conjunction with your high-resolution
grayscale display(s) is to set the color display as the primary monitor
of the Windows desktop. Then set the colors setting on the “Settings”
tab of the Windows Display Control Panel to the highest possible color
depth (e.g. 32 bits-per-pixel “true color”) supported by the color
display’s controller.
The colors setting for your high-resolution grayscale displays should
be set to 256 colors (8 bits per pixel). You should set the palette
mode for the your high-resolution grayscale displays to Static Gray
palette with NO system colors. This guarantees that all of the 256
gray levels available for GDI graphics will be present. This also
eliminates the danger that colors will change when focus moves
among different applications.
However, if you are using the Color to Gray Compatibility palette
mode, the color setting for your high-resolution grayscale displays
should default to True Color (32 bits per pixel). Even though this
palette mode supports 32 bit True Color, Barco recommends that
when using a using a color display in conjunction with your highresolution grayscale display(s) that you still set the color display as
the primary monitor of the Windows desktop.

Precautions
1. Optimize the lifetime of your display
Enabling the Display Power Management System (DPMS) of your
display (in the display’s Settings menu) will optimize its diagnostic
lifetime by automatically switching off the backlight when the display
is not used for a specified period of time. By default, DPMS is enabled
on your display, but it also needs to be activated on your workstation.
To do this, go to “Power Options Properties” in the “Control Panel”.
Barco recommends setting DPMS activation after 20 minutes of
non-usage.
2. Use a screen saver to avoid image retention
Prolonged operation of an LCD with the same content on the same
screen area may result in a form of image retention.
You can avoid or significantly reduce the occurrence of this
phenomenon by using a screen saver. You can activate a screen saver
in the “Display properties” window of your workstation.
Barco recommends setting screen saver activation after 5
minutes of non-usage. A good screen saver displays moving
content.
In case you are working with the same image or an application with
static image elements for several hours continuously (so that the
screen saver is not activated), change the image content regularly to
avoid image retention of the static elements.
3. Understand pixel technology
LCD displays use technology based on pixels. As a normal tolerance in
the manufacturing of the LCD, a limited number of these pixels may
remain either dark or permanently lit, without affecting the
20
Display information
diagnostic performance of the product. To ensure optimal product
quality, Barco applies strict selection criteria for its LCD panels.
To learn more about LCD technology and missing pixels, consult
the dedicated white paper available at www.barcomedical.com.
4. Enhance user comfort
Every Barco multi-head display system is color matched with the
highest specification in the market.
Barco recommends keeping color-matched displays together.
Furthermore, it is important to use all displays of a multi-head
configuration at the same rate to preserve color matching
throughout the economic lifetime of the system.
5. Maximize Quality Assurance
The ‘MediCal QAWeb’ system offers online service for high-grade
Quality Assurance, providing maximum diagnostic confidence and
uptime.

Room”) a preset value (“Preset”).
• In the case of “Preset” you must select a reading room that
corresponds to the type of room the display is installed in. E.g.
if the display is installed in a room where CT scans are
observed, the “CT/MR/NM” reading room is the preferred
selection.
• The reading room is defined by:
Maximum Ambient Light defines the maximum light allowed
in this type of room. This value can be adjusted within certain
limits determined by the selected reading room.
Preset Correction Value is the predefined correction value for
this reading room. This value can be adjusted within certain
limits determined by the selected reading room.

DICOM
Select a DICOM display function for most
medical viewing applications.
The DICOM function results in more visible grayscales in the images.
Dynamic Gamma 2.2
Dynamic Gamma 1.8
These are gamma functions that are
shifted to take into account the non-zero
luminance of an LCD panel when driven
with a “black” signal.
They are especially useful in CT applications to improve the perception of low
Haunsfield values.
Native
If you select Native, the native panel
behavior will not be corrected.
