How do you turn off Adobe Gamma on a PC?

greg gayne , Feb 09, 2005; 01:32 p.m.

I have a PC w/ a Spyder, Optical & a LaCie monitor. How do I make sure that Adobe Gamma is deactivated and is not screwing with the calibration that I'm manually doing?

Various means. One common way to temporarily disable programs that run in the background, is this (assuming Windpws XP, Win2000 is similar if not identical):

Launch the system utility MSCONFIG.exe. You can do so by clicking "Start" - "Run" , type in MSCONFIG.EXE, click "OK".

On the resulting dialog box, go to the "START" tab. This is a partial list of programs loading upon reboot of the PC.

Uncheck the box for "Adobe Gamma Loader".

Re-boot. PC will start up *without* AdobeGamma. There should also be an alert that some of your startup programs are disabled.

Windows has many sneaky ways to launch programs in background, with or without your knwoledge. Fortunately, AdobeGammaLoader is "out in the open", realtively speaking.

Oops, minor typo. Where I wrote:

"On the resulting dialog box, go to the "START" tab. This is a partial list of programs loading upon reboot of the PC."

It should read the "START UP" tab of the dialog box.

Adobe Gamma is actualy only loaded because it is in the "Start Up" folder of the start meny. To remove it, simply go:

Start > Programs > Start Up

Right click on "Adobe Gamma Loader" and select delete.

Note that deleting the shortcut link in the STARTUP folder permanently disables AdobeGammaLoader from loading.

To restablish AdobeGamma loading again, One would have to:

- locate the target AdobeGamma executable and create a new shortcut link in the Startup folder, or

- restore the deleted link from the Recycle Bin.

That's why I prefer disabling in MSCONFIG instead .. but it's Po-tay-toes vs Po-tah-toes

True, but once you have a Spyder, why would you ever want Adobe Gamma loader back!? :)

Tom Herman , Feb 09, 2005; 03:26 p.m.

Ahhh, yes.

Does the Spyder install its own equivalent "gamma loader"??

I am unfamiliar with its software.

I don't believe that the Spyder/Optical has anything like the Gamma Loader. The thing to know about the gamma loader is that it is completely unneccesary. The monitor profile needs to be in a specific location and Windows looks there for it. You can see this profile in the monitor control panel (settings/advanced/color management. The gamma loader just resets this to the Adobe Gamma generated profile every time the system starts up, if it's in the startup folder.

For this reason, there is absolutely no reason to use the method Tom suggests above. If you delete the Adobe Gamma from the startup folder, the same profile will still be used. If you use some other profile and then want to generate one with Adobe Gamma, you just run Adobe Gamma from the control panel. Using msconfig is sometimes unreliable - it's possible for applications to reactivate themselves, although I've never figured out how this happens.

I've recently come to believe that a "gamma loader"-like program is still necessary.

For an example, see the thread: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00B0H7

I was getting perplexed because defining a "default monitor profile" in "Windows Display Properties > Settings > Advanced > Color Management tab" was *NOT* modifying the behaviour of my monitor.

Only if Adobe Gamma Loader (or equivalent) was functioning, was my monitor getting its intending ICM profile.

It was explained in that thread that Windows "default monitor profile" only benefits application programs that are "ICC aware".

Perhaps PhotoshopCS is such a program, but Photoshop Elements 3 that I use, is NOT "ICC aware", and requires AdobeGammaLoader (or equivalent) for the monitor to display "correctly".

Viewing content in most other programs (eg Internet Explorer) also apaprently requires a "gamma loader" to install the correct monitor profile at bootup.
