Select Spyder Certification

Help Index

Usual Setting

The default value of this setting is ‘Off’. Enabling this setting depends on the users’
needs for display calibration status. This setting does not affect the actual calibration
process in any manner.

The Purpose of This Step

The user can choose to have the calibration status of the display monitored
continuously and to be notified if the display falls out of certification.

The Long Answer

Spyder Certification is a process carried out by the Spyder Utility which runs in the
background on your computer. Spyder Certified indicates that the conditions of a
particular display are within the parameters defined for certification.

Certfication status is indicated on the display by a small icon in the menu bar (on
Macintosh) or a small icon in the System Tray (on Windows). If the display is out of
certification the user can select an item from the Spyder Utility menu for an
explanation of what conditions have been violated and how to return the display to
certified state.

Specifically, the parameters which define Certification are:

•

The profile assigned to the display by the operating system is a Datacolor

Spyder3-created profile

•

That profile was created with Spyder Certification set to ‘on’

•

The LookUp Table (LUT) currently loaded in the video card is the LUT from

that profile

•

Ambient light conditions are the same as when the display was calibrated

•

The display has been recalibrated within the time limit specified in the

Spyder Utility’s preferences

•

The display has been run through full calibration within the time limit
