What’s New in Version 6.x Series
Dome Display Support has been added for the new Dome E2cHB display, a 2-megapixel, color, high-bright unit.
Windows Platform Support Support is available for the Microsoft Windows 7 (x86 or x64) and Windows Server 2008 R2 (x64 only) operating systems. Support for the Microsoft Windows XP x64 operating system was added to the Dome® CXtra™ 6.x series in an earlier version.
CXtra Utilities Users can start, restart, and stop all CXtra services and application, and run CXtradiag with utilities. Access the tools via the Windows Start menu. NOTE: Windows administrator privilege is required to run the utilities. Users without privilege must enter an authorized username and password as prompted.
Fast User Switching The Fast User Switching feature is not supported on display systems using NVIDIA drivers previous to version 197.03.
Installation Upgrades The installation procedure for Dome CXtra is now simpler, faster, and more reliable. All services and features are installed by default. To customize your installation, you must deselect the service or application feature you do not wish to install.
White Level Calibration Correction of the display white level can now be done via manual conformance testing or with the White Level Calibration service. A one-time, end-user calibration of the white level may be necessary when the target luminance is outside the tolerance established for proper display conformance, such as when the white level of a display has failed a manual conformance test, or when two or more displays in a multi-unit configuration show disparate white levels. An external photometer is required. NOTE: Privileged users and administrators can calibrate the white level if a display fails the White Level test during the manual conformance testing. Only administrators can calibrate the white level via the White Level Calibration service.
Support for 10-Bit Displays You can now run the Dome CXtra software on Dome 10-bit grayscale displays. You can check for 10-bit capability (both current and maximum supported) on the Properties tab of the Reporting dialog. You can also view 10-bit patterns (horizontal ramp and vertical ramp test patterns) using the Test Patterns service. And in manual conformance testing, you can take all 1024 measurements for more precise testing results.
Using Dome CXtra with Dome Dashboard For best practice of using Dome Cxtra 6.x with Dome Dashboard 2.x, observe the following requirement and recommendation. • When using Dome Dashboard 2.x, make sure that Dome CXtra 6.x or later is installed on each CXtra workstation. • On the CXtra workstation, limit the retention of history to 365 days (one year).
Single Dome CXtra Package The separate packaging of the Enterprise Management Service has been discarded. All Dome CXtra services, including the Enterprise Management Service, are now available in a single CD package.

Getting Started
The Dome CXtra software adds essential functionality to Dome medical imaging display systems in diagnostic and referral settings. By using the Dome CXtra suite of value-added services, you can calibrate and maintain displays, run acceptance tests, and monitor displays remotely. While the services operate as independent plugins, they each use the Reporting service for listing properties, logging events, and saving history.
Display Compatibility Dome CXtra services enhance the functionality of these display systems: • Dome CX • Dome EX • Dome QX • GX2MP • Select Desktops You can also install the Dome CXtra software on systems using third-party commodity monitors to enable DICOM calibration. See “Enabling DICOM Calibration on Third-Party Monitors” on page 53. NOTE: When you add or remove displays on the Windows desktop, you must restart the Dome CXtra software by rebooting the system. (Refer to ReadMe file for more information.) WARNING: When the Dome CXtra application is running on the system, power off the workstation before you either connect a DVI cable to or disconnect a cable from the Dome display. Connecting or disconnecting a DVI cable with the workstation power on may corrupt the display EDID data.

RightLight Service
The RightLight service performs backlight stabilization, DICOM calibration, and automatic and manual conformance testing for Dome CX and Dome EX displays. With RightLight, you can set a target white level, equalize the black level across the displays, set a desired response function, and specify ambient light in the viewing area. This service also reports current white and black levels. RightLight automatically calibrates the displays at regular intervals. Calibration adjusts the response of a display to conform to the response function you specify. There are four calibration response functions, one of which is a correction to the DICOM Grayscale Standard Display Function. DICOM calibration is based on the unique characteristic curve stored in each display at the time of manufacturing. RightLight routinely checks how well each display conforms to the DICOM standard and calculates a Luminance Uniformity Metric (LUM) value that indicates the degree of conformance. Besides the automatic conformance testing that RightLight performs regularly, you can perform manual conformance testing as desired, using an optional external photometer. You can also calibrate the internal RightLight photometer to generate a new calibration data file whenever the white level is outside the tolerances set for the display configuration. Calibrating the white level requires an external photometer.
RightLight Service | 13
For Dome E2c, Dome E3c, Dome E3cHB, and Dome E4c displays, you can set color coordinates for panel appearance in one of two ways: • Select an option for panel appearance with blue, clear, or default. • Use the LCD II photometer to perform color calibration when you specify color coordinates by color temperature (Kelvin scale) or by CIE xy coordinates.
Configuring the RightLight Service If the Privilege service has been installed, you must log on as a privileged user to change the RightLight configuration. (See page 96.) To configure the RightLight service 1 Open the Dome CXtra Services menu and select RightLight Panel Configuration. The RightLight Panel Configuration dialog appears with these tabs: • Backlight • Calibration • Ambient • Color • Auto (Conformance) Alerts • Manual (Conformance) Alerts 2 Check the selection box for each display you want to configure, or click Select All. 3 Select a tab and change the settings as described in the following sections. Click Apply to activate the changes without closing the dialog; click OK to activate the changes and close the dialog.
Backlight tab For displays selected, you can view the values of these parameters: • Black level in cd/m2 • White level in cd/m2 • Backlight use in hours • Brightness as a percentage of maximum effective brightness

To correct this problem, reduce the white level setting on the Backlight tab until the warnings stop appearing or use the Reporting Control dialog to disable the warning popups.
RightLight Service | 15
Dome CXtra gives you three options for controlling dynamic range of displays. • Maximize - Causes each selected display to be calibrated using its full dynamic range. The dynamic range of the selected displays may differ. • Equalize - Causes all selected displays to be calibrated using the same dynamic range. The system locates the selected display that has the smallest dynamic range and adjusts the dynamic range of the other selected displays to match it. • Specify - Causes all selected displays to be calibrated using the specified dynamic range. The system notifies you if any of the selected displays cannot achieve the specified dynamic range. If all the selected displays have similar dynamic range, there may be little or no visual difference among the selections.
The black levels and white levels shown on the Backlight tab include the ambient light level specified on the Ambient tab. NOTE: Choosing the Native or the No RightLight Calibration option on the Calibration tab or on the services menu prevents RightLight from equalizing black levels. When you do this, you are no longer applying DICOM calibration.
