Something like the white-point dialog that helps the user to set up his displays controls to restrict a wide(r) gamut display to within sRGB gamut by adjusting primaries and secondaries. So maybe another solution would be to at least offer a dialog for those displays that do offer saturation controls (like some less expensive Eizo displays that come with 6-axis controls, but no hardware calibration). I don't know if ArgyllCMS would allow for such things and how much work it would be to implement them. This would allow to get calibrated results with all applications.

As in mapping the oversaturated blue down to within sRGB/AdobeRGB boundaries, just like color management software does (maybe even with a choice of rendering intend). So my hope was that it should be possible to calibrate a display to a target gamut (sRGB) by desaturating the primaries and secondaries via software LUT. But unfortunately it desaturates a bit too much, thus decreasing sRGB coverage down from over 99% to less than 96%. The U2713HM does offer a sRGB profile that indeed does decrease the native gamut volume down to within sRGB boundaries.

The NVidia driver offers a general control that affects all RGB channels at once, but no way to desaturate single channels. My U2713HM doesn't offer saturation controls. But the myriads of applications that don't offer a color management workflow would benefit from calibrating the display (or GPU LUT) directly to the intended target gamut.

Of course this is the best way to ensure everything works to full potential and I do have access to several of these (including PS and LR). To have gamut correction, create an ICC profile and use applications that actually use it. Just to clarify: I don't mean white-point and hue, but gamut in general and blue primary specifically.
Is it realistic that white LEDs (blue + coating) have a blue-point (slightly) outside of even ProPhotoRGB?ĭefinitely not, as the ProPhoto blue primary is not a real color (it is outside of the CIE diagram).

If you don't have a spectrometer, you could use one of the generic corrections that are available for several display types (dispcalGUI allows import from iColor Display for example, which has a quite extensive selection of corrections, or in case of ColorMUnki Display/i1 Display Pro and Spyder 4 you can import the spectral corrections from i1 Profiler). Usually to increase trust level you use a spectrometer to create a correction matrix for the particular display/colorimeter combination. I do wonder, though, how much the profiling or rather probes (Spyder3, Colormunki) can be trusted with the blue primary? Video card gamma table calibration is an 1D process (for each of the three device channels, R, G and B), so it cannot correct a single channel without affecting whitepoint/grayscale hue. Well, you already said it: The way to solve this is to calibrate to a different (neutral) whitepoint.Īn option to calibrate for a target gamut with desaturation of the blue channel via software LUT would be useful for displays like mine. White (blue + coating) LED based displays come with far too saturated blue, which I would like to calibrate away via software LUT. I do wonder, though, how much the profiling or rather probes (Spyder3, Colormunki) can be trusted with the blue primary? Is it realistic that white LEDs (blue + coating) have a blue-point (slightly) outside of even ProPhotoRGB? The latter is useful for targeting web images without having to use softproofing (anything that looks good with the sRGB profile should turn out ok on any other non wide-gamut display). The former is useful for editing except for the oversaturated blues. The NVidia driver does not offer saturation/vibrance controls for single color channels, so having an option to desaturate (=decrease gamut) via (software) calibration would be nice indeed.Ĭurrently I am switching between native gamut and the built in sRGB profile/gamut. In my case I would tame the blues from oversaturation and keep all the other primaries and secondaries to their natively slightly larger than sRGB gamut (benefits visibly editing greens and reds in photos before converting to target color-space). This would allow to change the primary blue to within the visible range (or at least to within ProPhotoRGB or even just sRGB/AdobeRGB) while keeping magenta and green (and secondaries) at native points.

Or instead of a target gamut allow for manual primaries and maybe secondaries even.
