I’m trying to load a display profile using Adobe Gamma control panel. It seems I did this before successfully using Photoshop 6, but I’ve upgraded to CS and now I get the error; "The selected profile is not a legal RGB display profile."

I’ve tried to re-create the profile and it still doesn’t work.

Anyone seen this problem and/or have any ideas on a solution?

Thanks.

If you are using Monaco optix or EZ colour, do not run Adobe Gamma. If Adobe Gamma is in the startup directory, delete it from there and rerun your Monaco program.

Philo,

Yes I have already taken Adobe Gamma loader out of the startup directory so that only the Monaco loader is running. Still, it doesn’t work.

What are you naming the monitor profile?

I originally named it; "LMH Sony 122903 6500K.icm" but then thinking that maybe it didn’t like the file name I renamed the file to "LMHSony.icm" and that didn’t help.

Is there a name within the file that it doesn’t like?

I’m not sure if it Monaco saves as a icm or icc file. You might try not adding the extension. That was the reason I asked.

By default it saves it as an .icm. I’ve done it with the .icm extension and without. Without, it adds the .icm.

I have saved it with and without the extension. If I save it without, it adds the .icm.

It seems that Adobe is looking for .icc but it lists both .icc and .icm

I’m trying to load a display profile using Adobe Gamma control panel.

You don’t open a Monaco generated profile with the Adobe Gamma utility, nor do you open a Adobe Gamma created profile with your Monaco software. Why would you want to?

These are 2 utilities that do the same thing, ie:create monitor profiles. You either use Adobe Gamma to create the monitor profile or Monaco with their sensor (which should be MUCH better than Adobe Gamma).

Once the profile is created it should have been automatically set as your default monitor profile by the Monaco utility. To confirm that it’s done so: Right-click on your computer’s desktop, select PROPERTIES -> SETTINGS -> ADVANCED -> COLOR MANAGEMENT. In there you should see the name of the profile you created (THIS is where you manage your profiles, NOT in Adobe Gamma). If it’s not there then simply select ADD and scroll down the list to find the one you created. After adding it you should also highlight it and select SET AS DEFAULT -> APPLY just to be safe.

Photoshop (or any other ICC aware application) will now know to use the default monitor profile for its purposes.

If you want to confirm that Photoshop is using the correct profile you can open Photoshop and open COLOR SETTINGS and in the SETTINGS pull-down menu at the top select COLOR MANAGEMENT OFF. If everything is working properly you’ll see your monitor profile displayed as the RGB working space.

Note: You normally don’t want to use Photoshop in this COLOR MANAGEMENT OFF mode and should reset it to a device independent RGB working space such as sRGB, AdobeRGB or whatever you prefer. But this quick test will confirm that Photoshop is aware of, and using, the correct monitor profile to display images properly on your screen.

Bottom line is that Adobe Gamma is only a free utility that does the same thing as your Monaco hardware/software (just not nearly as well). It has no purpose except to create monitor profiles that are used by your system as outlined above. It has nothing else to do with the proper functioning of Photoshop. If you use Monaco hardware/software to create your monitor profile then you have NO NEED to ever use Adobe Gamma. Get rid of it.

Russell,

Thanks for your response.

I am trying to use Adobe Gamma to load the Monaco profile since that is what Monaco instructs in a document on their website. According to the document;

"Before you can use your monitor profile in Adobe Photoshop, you must configure your O/S to recognize your monitor profile. Adobe Gamma.cpl, a control panel installed with Adobe Photoshop 5.0.2, is used to create and load monitor profiles. Adobe Gamma Loader.exe is a startup utility that loads the settings saved in the Adobe Gammea Control Panel. Adobe Photoshop uses the monitor profile last saved in the Adobe Gamma Control Panel. …"

It goes on to tell how to turn off Adobe Gamma Loader so as not to interfere with the Monaco loader.

What I suspect is that this document doesn’t apply if I’ve already loaded the profile into Windows, which I have, or applies only to earlier versions of Photoshop which don’t grab the profile from Windows. In checking Photoshop as you described, I see that the correct profile is indeed loaded.

Looks like Monaco needs to update or correct that document.

Thanks for you help!

If those are indeed the instructions from Monaco then they’re just plain WRONG! Photoshop uses the profile stored in your PROPERTIES -> SETTINGS -> ADVANCED -> COLOR MANAGEMENT folder and that’s where Photoshop goes looking to see what it’s supposed to use. End of story.

If you used Adobe Gamma then that’s where it would put the one it created as well. Sounds like it was written by a misinformed Mac user who needs to do some homework before writing ‘how-to’ documents for PC users.

Note that Monaco’s online demo of MonacoProof ends with "The profile is stored in the correct system directory for your operating system" which is correct. There’s no need to do ANYTHING with Adobe Gamma to have Photoshop use it.

What Russell says is correct. If you are using Monaco monitor profiling software, you should not use Adobe Gamma at all. Not in startup, not later, never.

Sounds like a very old version of Monaco software if they make reference to Photoshop 5.0.2. Back then ICC based CM was very new and a lot of folks (vendors included) were not too clear on how it worked, especially on Windows systems. Maybe back then this suggestion might have been true, though I doubt it. Anyway…since Photoshop v5.5, which is the 1st real ICC colour managed version of Photoshop, this is definitely NOT the way it’s done. Glad I could help 🙂

Happy New Year!
