Yes.
okay.
Could you please make another screenshot with my third monitor profile set for both LCD and Asus - that from above (the last one) but in addition the same image opened in the Mac preview and in Safari.
(close all applications before you set the new monitor profile in ColorSync and restart them afterwards)

I assume you mean "AsusVW192S_modified.icc" ?

I set both monitors to this profile, then opened the spin file in Photoshop, went to 'save for web', then opened spin file in Safari and Preview:

yes, that's right.
Sorry... the gamut of that "spin" profile is quite small. I still think that the image viewed in the regular Photoshop window is less saturated.
Could you do the same screenshot but not with the spinned image but with your AdobeRGB original file?

and in a second step: same procedure but with ProPhotoRGB set as monitor profile for laptop and TFT.

Step 2, but I should point out that it looked nothing like this on screen. The images were far far less saturated, rather grey looking, in fact, except for the bottom-left image which looked normal.

FIrst step:
hey - we are closer now (or am I colour blind?).
The sole image that is different here is the left preview in the "safe for web" tool.
At the beginning of the thread I asked you to use the "safe as" command.
What happens if you convert your AdobeRGB image to sRGB and then "safe as" JPG and open it in Mac Preview (or Safari or both)?

brilliant. Don't worry about saturation. For the screenshot your display profile is assigned and that's why it looks different here.
Essential is only: what matches and what matches not. And it's only the "safe for web" tool that is off (only on the left side) while the rest is on a par.

So: there is a bug with the "safe for web" tool, okay.
BUT: you can work with my third Monitor Profile as this seems to work - at least in a way that you can work in Photoshop and convert to sRGB and get the same in the web (actually you could use the "safe for web" tool as well but you should ignore the left image and compare the regular Photoshop window with the output of the Safe for web" tool on the right side).

I think we did this at the start so we're going round in circles  

It produces a more saturated sRGB file than what we see in Photoshop. It's like Photoshop is using a different sRGB profile to the rest of the world (and I think I said that in the first page already  )

please convert again to sRGB but switch the CMM to Apple CMM before (you can set it directly in the "convert to" dialogue).

did you set my modified (3) monitor profile?

Can you send me a TIFF or larger JPEG shot from your computer without "Save for web"? So i will check what is the problem excatly, i used to have this problem before but i fixed it, i was using CS2 but then upgraded to CS4 and no problem at all with any, even using LR or DPP or Aperture or FlexColor, all giving me accurate correct color [if correct WB and exposure ofcourse] and all matching my prints and also same on my internet browsers.

Ok, I ran 4 tests and I have a hunch I might know the answer, so I'll test that in a minute.

Anyway, the results.

My regular profile, CMM:



My regular profile, ACE:



Your modified profile, CMM:



Your modified profile, ACE:



As you can see, Photoshop is now behaving as expected, displaying the sRGB file the same way as other programs. So what changed? I'm about to test for a hunch... fingers crossed.

indeed! looks good!
My idea was that your Photoshop colour manages with a generic monitor profile though the monitor profile set in ColorSync shows up correctly in the list. But the "ProPhoto-Test" shows that it adresses ProPhotoRGB as monitor profile here.
well, I'm curious...

And I can reproduce the problem:

:D:D:D:D

All I changed was the profile of my Macbook monitor profile back to it's own profile, and I am back to the old problem (keeping my external monitor on my regular profile).

My Macbook screen died recently, so I never use it any more and that's why I have the external monitor. Keeping it on the same profile as my external monitor is no problem. I'm guessing that this problem started happening around the same time that I switched to an external monitor!

So what's going on? Is either the OS or Photoshop getting confused between profiles?

Oh, and I would never have worked this out without you. Thank you so much. If you're ever in Tallinn the beer is on me

This seems like a serious bug from either the OS or Photoshop.

Yes, I reverted back to my normal setup after doing your Prophoto RGB test on both monitors. Using the right profile for each monitor should work!

should but does not!  
Don't change the conditions while testing. Change them afterwards for further tests :-)
Good that it's solved now!
