i’ve just started using photoshop CS4 and noticed today that enabling OpenGL drawing under performance preferences (GPU settings) disables color management for my 2nd dual monitor.

2.4ghz intel core 2 duo, 4GB 667mhz, mac os 10.5.6 (fully updated 1/7/09) GeForce 8600M GT, 256MB

Have you tried toggling the "Color Matching" check box under Edit – Preferences – GPU Settings – Advanced Settings – Debugging?

I assume you had dual calibration working and your card has dual LUTs since you need them to run profiles on two displays from one card. CS4’s use of the GPU for color matching has some issues in both Photoshop and Bridge that I’ve run into.

i’ve tried toggling every conceivable combination of those buttons under the advanced settings, but only toggling it off completely seems to resolve the issue.

have both monitors properly calibrated and the color management between the two works fine when the openGL is turned off. hope this is just a bug that will be fixed…
