The video card needs to be configured to assign different settings to each monitor (how it's done depends on the videocard drivers).
More importantly on a dualhead card under Windows XP one would need to download a Color Control Panel utility from Microsoft and set it to be launched on start-up (with an /L switch as stated in the Help file) to load LUTs, plus disable other colour utilities to avoid conflicts.
Serge additionally commented:
- --Technically only dualhead AGP card owners need to use the appet to be able to assign separate profiles. Some PCIe cards don't need it since Windows XP sees them as two cards in the device manager (and obviously systems with two separate cards don't need it either). However the applet lets you see your color management in a much more organized way that makes much more sense no matter which configuration you use. It makes the adjustments much easier.
- Another important aspect of the color applet (which can be regarded as a separate application actually) is it's optional startup LUT loader.
- My general suggestion for XP dualhead card users would be to replace their LUT loaders in the Startup folder (Adobe Gamma, Colorvision, Eye-One) with a shortcut to Color Control Panel Applet LUT loader. It won't hurt in any case and it would work with dual-monitor aware software like Spyder2 Pro without any further configuration.
- Normally the shortcut would be to:
"C:\Program Files\Pro Imaging Powertoys\Microsoft Color Control Panel Applet for Windows XP\WinColor.exe" /L
- The "/L" part you can add by right-clicking on the shortcut and adding /L it in the Target field. " --
Not all calibration software supports dual monitors, so you may have to run your system with each monitor on it's own to get profiles that you can then select when working with both.
Amongst the features of the control panel:
- Install and uninstall ICC colour profiles
- Inspect, rename, and compare two different colour profiles
- Associate colour profiles with devices such as printers, monitors, and scanners
- Apply custom colour gamut adjustments to one or more displays on the fly
- Set up display calibration reminders at intervals you specify
- View a 3D graphics plot of colour profile colour gamuts
There is more information, and you can download the software from:
I discussed some profile editing issues in the review of the Spyder2express, where you need to rename a profile's internal name for dual monitor support. The Applet can be used for this.
Useful discussions about this subject on the web
There are (many) more technical discussions about it on this message board (Rob Galbraith) and there has been a lengthy discussion in the ColorVision Yahoo group about using a Spyder2 for matching two monitors. http://groups.yahoo.com/group/colorvision_group/message/316?threaded=1

General Colour Management
- Calibration and profiling - not the same thing Monitor calibration or monitor profiling? I probably know what you mean, but actually they are two different things. A short explanation for the usage of the terms that I try and stick to in reviews and when writing about colour management.
- Adobe utility for printing profiling targets (CS5) with no colour management.
- CMYK for photographers (1)
Some considerations when a client asks for images to be submitted in CMYK
- CMYK for photographers (2) - Press management
An overview of colour management for when your work is destined for large scale printing.
- Why don't my prints match my screen?
A short article showing why there is more to getting your prints to match your screen, than just calibrating your monitor. It's the vital first step, but you do need to consider some other factors for best results.
- Why are my prints too dark?
One of the more common printing problems we get asked about. Addresses some of the steps you can take to produce more consistent prints.
- Dark prints revisited - If you're having problems adjusting your monitor, Keith has some details of an experimental approach, using adjustment curve layers that may be of some help.
- Choosing a working space
There are a number of popular choices for working colour space when editing images. Keith shows examples and discusses his personal choices for different applications. One size definitely does not fit all.
- Room and office decoration and lighting for photo editing
Some information on what to consider when setting up a space to work on digital images and evaluate prints.
- The very simple guide to 'what is colour mangement'.

- Colour management introduction
- Beware the colour management Tar Pit
Know what levels of colour management (and expense ;-) suit the needs of your work... A personal view from Keith covering some of the things it is good for, but also why you should be careful to understand why you are doing it in the first place.
- Printer test images
- Media settings and profiling for third party inks
Keith recently converted an Epson Stylus COLOR 1160 to third party inks. In describing the profiling of a this set-up with a third party glossy paper, he shows how that often neglected aspect of profiling -driver media settings- can make all the difference between a so-so print and one that he would be happy to send out as a sample to his commercial clients. Test images for media selection.

A special version of our black and white test print for reading linearisation data for QTR
- Using QTR and PrintFIX PRO for better black and white prints
By using the PrintFIX PRO to take readings from a greyscale test target, you can create luminance only icc profiles that can give a noticeable improvement to black and white print set-ups. It can even be used to improve the results from the likes of Epson's new 'advanced black and white' print settings.

Sept. 2008 X-Rite and the i1 range
From Sept. the range is simplified to two options. The functionality is the same as we have reviewed, but exactly what you get varies. As a result of this rationalisation, the i1Photo, i1Photo SG, i1Proof and i1XT have all been discontinued, and the i1 range now consists of:
- The i1Basic - i1Pro measuring device with monitor profiling software
- The new i1XTreme - professional monitor, RGB and CMYK printer, camera, scanner and projector profiling, plus profile editing
With the i1XTreme you can calibrate and profile:
- Monitors - LCD, CRT and laptops
- RGB output devices
- CMYK output devices
- Digital projectors
- Digital cameras*
*Requires Digital ColorChecker SG Chart - available separately.
