windows 7 - Calibrating Displays in Boot Camp 3.0 on MacBook with external display
2013-08
Questioner
The LED display on my MacBook Pro is very blue-ish without correction. In OS X the advanced mode of the display color calibration tool is excellent and I can largely color-correct the display. Windows 7 incorporates a color calibration tool but it is less powerful. It largely consists of a software gamma correction tool and color charts to use with the hardware controls on your display (which don't exist on a notebook or an apple external display). How can I color-correct Windows in Boot Camp to match the OS X correction without using a Spyder or other special calibration hardware?
Starting with Vista, Microsoft bundles support for ICC color profile calibration with the "Windows Color System." Even though Vista doesn't include a tool to create ICC profiles and the tool in Windows 7 is very basic, you can load any profiles that you generate by other means.
If you use the advanced display calibration wizard in OS X, it will generate ICC profiles for you. If you save the profiles for "all users" they will be stored in a central location. Then you can load and use them in Windows because Boot Camp 3.0 provides HFS+ drivers to mount the OS X system volume.
After you do the calibration in OS X, restart inot Windows. The calibrated ICC files should be readable on your "Macintosh HD" volume. On my machine they are in E:\Library\ColorSync\Profiles\Displays.
Right-click on the .icc files and choose "Install Profile". Then you can use Control Panel > Display > Ajust resolution > Advanced Settings > Color Managment to load the appropriate ICC profiles for each monitor. You can use the Advanced tab to set the default color profile per display for all users.

I've got nice-to-have problem: my new monitor (Dell 3008WFP) has wide color gamut and displays too saturated* colors (magenta and cyan look almost fluorescent).
I'd like to get colors closer to saturation of an average monitor (sRGB?), but preferrably without sacrificing ability to display more saturated colors in color-profile-aware software.
In my monitor's settings I've set color to "Adobe RGB".
OS X recognized my monitor model and has factory profile for it, but I'm not sure if that's appropriate profile. Regardless whether I choose my monitor's factory profile or "Adobe RGB (1998)", colors still look too saturated, and gamma is too low (dark shades are too bright).
I've used Display Calibrations Assistant (in Expert mode) already, and it's not enough. I was able to adjust gamma and temperature, but it doesn't alter color saturation.
Which profile should I choose in Display settings? Should I create my own profile? Can I do it without hardware calibration tool?
Is it even possible to tell OS to limit colors to certain profile for profile-less graphics (e.g. icons, images on the web) and use full capabilities of the monitor for images with color profiles?
*) by "too saturated" I mean more saturated than I'm used to, regardless whether that's theoretically correct saturation or not :)
Edit: I've found Firefox about:config settings that achieve desired effect (but in browser only, I'd like that system-wide). It's mode=1 full color management of all content (including untagged) with rendering_intent=3 ICC-Absolute colorimetric and Adobe RGB (1998) display profile [the same profile set in OS's settings doesn't achieve desired effect].
Edit 2: Snow Leopard solves the problem! (well, mostly – after I've sorted out gamma and saturation, subpixel font smoothing looks odd…)

I found this which may help:
I prepared this web color tutorial to test, review and troubleshoot internet color problems with the Apple Macintosh OS-X ColorSync® because I was seeing greatly over-saturated colors on the web.
Specifically, how the new so-called wide-gamut LCD panel flat monitors display untagged RGB color in a color-managed web browser like Safari for the Mac OSX and Windows XP Vista operating systems.

Reading through it myself as i find colour calibration an interesting topic! ;-)

Mac OS X's color calibration wizard allows you to customize the profile for the monitor... It does affect the color space of the monitor...
Chances are that you need to change the Target Gamma & Target White point. Those are settings that are very user specific.... So, try the settings... You can't break anything...
But I would suggest 1.8 gamma, and Either D65 or Native for the white point.

I use these settings on my Dell 2709W; my home office has a lot of natural light during the day. From the monitor's controls:
Quick Menu
Brightness: 0
Contrast: 50
Preset mode: Adobe RGB
Color Settings
Gamma: MAC
Mode Selection: Graphics
Display Settings
Sharpness: 80
On OSX, I used the monitor calibration in expert mode for the settings that looked best to me after setting the above. It does take experimentation because everyone's preferences, and ambient light in the room will have an effect on how things look too.
To me, my monitor looks very close to the native LCD of the Macbook Pro it is attached, which I never changed from the default because it is clear, crisp and perfect colors for me.
