iMac running 10.8.5
2nd Monitor, natively profiled NEC PA272W
When I drag the Preview Window to the second monitor it does not apply the correct colour profile so the image looks terrible.
I don't have the same problem with Photoshop where I can have a split window across both monitors with corrected color on both halves.
The color profile gamut symbol at the top right of the screen is saturated (i.e. active).
Any thoughts???
