ArgyllCMS delivers very good results when using a colorimeter in combination with a "standard" TFT, meaning normal backlight, no extended gamut and no LEDs to illuminate the screen. Now, widegamut TFTs become more and more popular and different techniques like LEDs are used to drive the screen. While that does not pose a problem in conjunction with a spectrophotometer, I know that colorimeters are calibrated to a certain spectrum for the standard lightsource used in a monitor. The iColor software, developed by Quato, includes correction matrices for their inhouse-monitors when used with a colorimeter, and they even provide a "generic" correction matrix, when using a colorimeter and a widegamut screen. How does ArgyllCMS cope with this, are there any plans (or even just data on the deviation) for the future? I find that not only software developers have to face the problem of designing their software so that it uses some form of CMM, but that the profiling process itself is affected by the changes in display technology.
