" You do calibrate and profile your display, you do not calibrate Photoshop. All you do with Photoshop is set the preferences correctly, give them a named preset and set that as a newdefault. "
Got it. My Display already =calibrated.
Photoshop =left alone.
I'd read that leaving it alone makes PS's profile default to whatever the monitor is, as already set up.
So what do I have to do according to the rest of your above?
