Introduction Introduction To use NioWatch The NioWatch application resides in the Windows systray. To use one of the NioWatch functions, right-click on the NioWatch systray icon and select the appropriate option: • Display settings: Allows to view information about your display(s) and display controller.
Installation Installation NioWatch installation 1. Insert your NioWatch CD into your computer’s CD drive. If the NioWatch installation start screen doesn’t appear within one minute, browse the contents of your NioWatch CD and double click on the file: “Setup.exe”. 2. Click “Install Now” on the start screen to begin the installation. Figure 3: NioWatch installation start screen 3. Click “Next” on the Installshield Wizard welcome screen. 4.
Installation Barco LCD sensor installation In case you will be using the Barco LCD sensor with your system, you may have to install its driver. The Barco LCD sensor is a USB device. Connect the sensor to a free USB downstream connector. When you connect the sensor for the first time, the “New hardware found” wizard starts. In that case, locate the appropriate driver file (.inf file) on the NioWatch CD-ROM in the folder “BarcoLCDSensor”.
Display settings Display settings General Figure 4: Display Settings dialog The numbered icons in the upper part of the dialog represent the display controller heads supported by NioWatch. The display controller heads are also listed in the Display dropdown box. If you wish to control a display in a multi-head system, you must select the display controller head to which the display is connected.
Display settings numbered icon or by selecting the corresponding display controller head from the Display drop-down box. Tip: If you click on a numbered icon, the corresponding number appears for a few seconds on the display connected to that display controller head. In that way you can easily see which display is connected to which head. The Display settings allows to view information about the display. The Graphic Board tab allows to view information about the display controller.
Display settings to this calibration. If no former calibration was found, default factory settings are selected. When you restart NioWatch, the last selected display function is automatically selected. The following display functions are available: 8 Name Description 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.
Display settings • To select another color temperature, select an item from the Color Temperature drop-down box. This function is available for E-2320 C displays only. After selecting another color temperature it may be necessary to recalibrate the display. Therefore, check the Calibration tab to see if calibration is necessary: In case the display is still in calibrated position, the text in the calibration tab will say ‘The selected display is calibrated ...’.
Display settings Graphic Board tab Figure 5: Graphic Board tab Here you can see information about the installed display controller: Name, serial number, driver version and firmware version.
Display settings Calibration tab Figure 6: Calibration tab Here you can calibrate display(s), revert to the latest calibration, revert to default factory settings and view the result of the latest calibration. The possible options are explained below. Things to consider before starting calibration: 1.
Display settings 2. If you have multiple Nio displays of the same type connected (multi-head system), consider if you wish to equalize the display you calibrate to a reference display. The first calibrated display in the system is the reference display. Equalization means the luminance of the display you are calibrating will be matched to the luminance of the reference display.
Display settings 5. Follow the guidelines on the screen to complete the calibration successfully. Note: If the Equalization option is set in the Application Settings and NioWatch finds at least one other display of the same type that is calibrated, the “Match with reference” page appears during the calibration process. Figure 8: Match with reference To equalize the display, check the option “Match this display with display....” and click Next.
Display settings 2. In the Calibration dialog (see step no. 3. in the description of the calibration with sensor), check the option Visually and click the OK button. The DICOM Optimizer dialog appears. Figure 9: DICOM Optimizer dialog 3. Adjust the slider until there is almost no visible difference between the background of the image above the slider and the bitmap inside this image. 4. When done, click button Set point 1 of 20. 5. Repeat this procedure until the button is grayed.
Display settings 3. In the next dialog box, select option Reset to the latest user calibration and click OK. The calibration and the luminance will be reset to the latest calibrated position. Note: When you start up the system, the calibration is also reset to the latest calibrated position. The luminance, however, is kept at the latest value. To view a graph showing the result of the latest calibration: 1. In the Calibration tab dialog, click on Show calibration chart.
Test patterns Test patterns Test Patterns Figure 10: Test Patterns dialog 1. Select the desired test pattern by clicking on the corresponding thumbnail or selecting a pattern by name from the Test pattern drop-down box. 2. Click Show to display the pattern. If you have selected Custom Image, you can select a bitmap image (e.g., saved on the hard disk) as test pattern. 3. To hide the test pattern again, click inside the pattern.
Application settings Application settings General tab Figure 11 Here you can check the option “Only administrators have full access”. When this option is checked, calibrating, resetting calibration and selecting another display function can be performed only by users with administrator rights on this workstation. This option can be checked and deselected only by users with administrator rights on this workstation.
Application settings Calibration tab Figure 12: Calibration tab Equalization Here you can check the Equalization option, allowing you to match all the displays from a multi-head system to the luminance of the first calibrated display of the system. Suppose you work with a system containing 2 Nio displays of the same type, and you wish display (2) to have the same output luminance as display (1). Therefore first calibrate display (1). Next, calibrate display (2) while the Equalization option is checked.
Application settings c BAR CO d BAR CO (1) Reference display (2) Calibrated display: Luminance automatically matched to reference display Figure 13: Dual-head equalization Note: The Equalization option will be available only if the system contains at least two Nio displays of the same type. To equalize the displays: 1. Be sure the reference display is calibrated to the desired luminance. 2. Set the Equalization option in the Application Settings dialog. 3. Close the Application Settings dialog. 4.
Application settings MediCal Administrator tab Figure 14: MediCal Administrator tab Here you can connect to MediCal Administrator, if present. To connect to MediCal Administrator, click the MediCal Administrator button. As a result, the MediCal Administrator connection wizard starts. Please follow the guidelines from the wizard.
Update NioWatch Update NioWatch In the Windows Start menu, the Update NioWatch application is installed during installation of NioWatch. To update NioWatch: Select Update NioWatch from the Start > Programs > Barco NioWatch menu. The application will search via the Internet if NioWatch updates are available. If so, you will get the option to install them.
