Problem: No supported calibration sensor was detected.
Solution:
• Try reconnecting the calibration sensor and click the Auto Detect button in the Preferences dialog to re-
detect the sensor.
• It may be necessary to close and re-launch the SpectraView application.
• (Windows) It may be necessary to install the drivers for the color sensor device. Note that only the drivers
for the X-Rite i1 devices are installed by the SpectraView setup application. Drivers for other devices must be
installed manually.
Problem: Severe color banding appears after calibrating on images and when the test pattern is shown.
Solution:
• Always use a DVI or other digital video signal if possible.
• If an analog video signal must be used perform the following steps once prior to calibration:
1. Display something on the screen that has both full black and full white, such as the Test Pattern in
SpectraView.
2. On the monitor's On Screen Display, select and operate the AUTO CONTRAST control.
3. Proceed with the calibration.
Problem (Windows): The ICC profile generated by SpectraView does not appear to be correctly installed and recog-
nized in Windows.
Solution:
• This problem may occur especially when using a multi-monitor configuration. In some cases updating the
video driver may fix this issue.
• The profile can be manually assigned if necessary as follows:
1. In the Windows Display Properties control panel, select the Settings tab and click Advanced.
2. Select the Color Management tab on the Display Properties dialog.
3. Find the color profile generated by SpectraView and use Set As Default.
• A more advanced control panel is available from Microsoft for Windows XP which is much more reliable
for checking the assigned monitor profile. On the www.microsoft.com website, search for "Color Control Panel
Applet".
Problem (Windows): SpectraView is unable to save the generated ICC profile.
Solution: If SpectraView is unable to save the ICC profile for this reason it will prompt you with the name and location
of the file that needs to be manually deleted in order to replace it with a new profile.
• This issue may occur if there are multiple users assigned to the machine. An ICC profile created by a user
can normally only be updated and replaced by that user, or an administrator. Starting with Windows Vista, even if
you are currently an Administrator, applications do not normally allow full administrative privileges by default.
You can either delete the current ICC profile manually (in which case Windows will ask for administrative level
credentials or permissions), or you can re-run SpectraView "as Administrator" by right-clicking the application
icon and selecting "Run as administrator". This process needs to be done once each time the user who created
