Our recommendation for CG monitors :
Whitepoint: In practice it is common to align the monitor's whitepoint with a Daylight hood (and not with ambient light). This means D50, or 5.000 Kelvin. For proofing with daylight or for photography, D65 is most common. Gamma: It is recommended to choose the tonecurve characteristic of the monitor in such a way that it approaches the working colour space best. Doing so, colour management of the application or operating system does not have to correct the tone values for viewing too much.
Examples: PhotoRGB, AdobeRGB, sRGB are based on a Gamma characteristic of 2,2. In this way, the monitor should be calibrated at 2,2 ECI-RGB at a gamma of 2,2.
The L*-Colour Space does not have a Gamma function. All in all, for all these recommendations, we're talking about the finest nuances. Colour Management takes care of the monitor's prophile, which uses the set Gamma, when it calculates the visualization. In order to avoid Banding, it is recommended to choose the Colour Space Gamma. Or one works without Gamma but with L* on monitor AND Colour Space. Only the lighting of the proofs will be unknown to the colour management. So, it is useful to choose Whitepoint according to the lighting of the proofing, and not to the one of the colour space.
Our recommendation for the Flexscan Monitors is Gamma = 2,2 and Whitepoint=6500
