Most of the time my cinema display works fine. But sometimes when i drag a window across to it, it will appear wrong.
E.g. If i drag a google chrome page (or other window), across, when i see it on the cinema display it is just a large white box.
If it's half and half, the side which is on my laptop monitor works fine.
I can still interact with the blank box, just not see what i'm doing.
The only way to stop the problem, is to go into display preferences and change the colour profile a few times.
Any ideas of where to go from here.
