I just remembered today that the Samsung 2243BWX monitor I purchased recently came with a pre-made (or ‘canned’) ICC profile.
For interest, I decided to compare the canned profile with the Spyder 2 colorimeter ICC profile using the Chromix ColorThink software.
The 2D view of the profiles show the canned and measured profiles follow each other quite well, except in the area of blue to red transition. It also shows they are off-set slightly.
Investigating the 3D view (canned profile in solid, measured profile in wireframe), shows the reason for the offset is that the white point has a different placement in two profiles. Rotating the 3D view I checked the black points and they located in the same place.
Conclusion:- The canned profile will probably do for the everyday computer user, but anyone serious about colour accuracy and management should be profiling their monitor.
