Victoria asked me to post this here -

I am going away in 8 days, and have again tried every fix in your blogs and on your user site - none worked. Updated drivers, reset preferences, confirmed Monitor Profile is not corrupted, ...

One new thing I noticed this time - while the Develop image which is adjusted in real time as I make changes looks like a negative, and is unusable - if I click on Secondary Display it is perfect. If I manipulate the levers, this image will show the changes correctly, but the process is too cumbersome as a standard operating procedure.

Can you provide any more insight into why the Develop image is unusable ?

Thanks,

Richard

And could we see an example of the problem?

There are two things that come to mind. The first one is GPU accelleration. Is it turned on in the preferences - performance? If so, have you tried what happens when you turn it off?

Second, you say you have confirmed that the monitor profile isn't corrupted. How did you confirm that? What monitor profile are you using?

Probably you need to go to Preferences->Performance tab and uncheck the "Use Graphics Processor" box.

Thanks for all the speedy replies !

And the winner is .... Hal !

But actually, Victoria did reply anyway - and when she saw what I had already tried - she had the same suggestion.

And it worked, perfectly !

Thanks again everyone.

Whilst Hal was undoubtedly correct, Johan actually posted more or less the same answer one minute earlier, so I would think they both should be regarded as the winner!
