If you're the “get it done quickly” type, the Spyder 3 Express is the way to go. Which approach is right? Both of course, and that's why it's nice to have options. Others are more practical, and just want good results with a minimum amount of time or effort. The 'Express' will do multiples just fine.Some of us are controls freaks - we want total control over what adjustments are made to our systems, and to have the ability to tweak each setting until we have what we feel is the perfect solution. Yes it's a little messy but you really do not need the more expensive multiple monitor version. Exit the graphics menus and confirm the new independent calibrations can be enabled and disable using the SpyderExpress system tray tool. Repeat Steps 9-12 for monitor 2 and confirm setting are similar to those shown below. With the new profile for monitor 1 now in the profiles list, 'Set as Default Profile'. Click 'Add.' and navigate through the list of profiles to find the profile you created for monitor 1 using the 'File name', not the profile 'Name'. Select the 'Device:' monitor 1 and make sure the check box 'Use my settings for this device' is selected. Go into Screen Resolution settings (right click on the desktop), click on 'Advanced settings', select the 'Color Management' tab and click on the 'Color Management.' option. The next part is a little tricky and may be dependent on the menus in your graphics setup. Locate the new 'Spyder3Express.icm' file for the second monitor and make a copy of it in the same directory, in my case 'Spyder3Express-FP222W-20121005.icm'. Repeat Steps 3-5 as above but this time select monitor 2 as shown below and calibrate it in the same way. Locate the newly created file 'Spyder3Express.icm' and make a copy of it in the same directory, in my case 'Spyder3Express-AOC2236-20121005.icm'. Using file explorer, navigate to the profiles directory 'C:\Windows\System32\spool\drivers\color'. Perform a standard SpyderExpress calibration procedure on the selected monitor and confirm colour has been corrected as expected. Go into Screen Resolution settings (right click on the desktop) and change the display to only use monitor 1 as shown.
Install the SpyderX Express drivers and software but do not begin any calibration. Get your dual monitor desktop configured and working the way you want.
Feel free to ask questions if this does not work for you. I apologize for this rather terse set of instructions. Here is my successful solution providing monitor independent calibration for two monitors, an AOC and a BENQ. Rather than being forced to pay for an upmarket product with multiple monitor support I decided to find a work-around. The 'Express' is an inexpensive entry level product designed only to support a single monitor. Looking for help on this issue I kept getting the same message that I need to pay double for the model which does support multiple monitors. Recently however I upgraded to a new Windows7 dual monitor desktop and officially the Spyder3 Express no longer worked for me. I have been using my trusted Spyder3 Express in a WindowsXP environment for a few years now to calibrate my monitors and ensure consistent colour and tone rendering between computers.
