Dont worry aobut it. What you are seeing is the image being rendered for one monitor as you are trying to view it on another. You have two separate monitor color spaces and one file color space. What you are seeing is the wrong monitor profile rendered to the image.
Make sure both of your monitors are calibrated and get some work done. Color accuracy is not important.
Thanks for the input Mike, however it doesn't help me. I'm actively working with both monitors and I need the colors to be accurate on both in order to do my job. I'm hoping there's a setting much like there was in CS4 (see my link in original post) so that I can get both monitors to behave the same.
I should also mention that this problem is unique to Photoshop, I do not have this color shifting problem in any other program (including, for example, Acrobat Reader).
That is a calibration issue - the calibrations are not quite right, and leave a bit of color cast on both displays.
Photoshop is using the profile for each display to correct the color for that display, but the calibrations are a little off, so the corrected colors don't match.
With LCD displays, this can be exaggerated with angle depenedencies of the LCDs.
Thanks for the reply. I find it curious that it doesn't happen with other programs (colors match in every other program). Is Photoshop the only program that uses the calibration settings?
Where within Photoshop might I set the calibration?
I tried setting it in Edit > Color Settings but was unsuccessful in achieving a change.
(I should note the difference is dramatic and as can be seen in my attached image example, not a monitor display angle issue).
