PC not holding ICC profile

[nospe7880]

I have managed to sort out the ICC profiles and the relationship between monitor and printer..the prints are getting there now Thanks for all the advice ..

My issue now is that my PC is not holding onto the profile for the monitor.. I have to keep telling it to use the ICC profile as default each time that I log in.. Is there a way to get it to hold the ICC profile and apply it each time ?

I have tried various things but to no avail.. could it be my video card that is resetting it? It is fine once I have reset it but it's annoying having to keep doing it..

Windows 7 = OS

Thanks in advance

Why not just recalibrate the monitor and then apply the new profile. The system you are using to do that should place the profile in the correct location and on start up you should notice a slight change in colour and brightness when the profile is loaded. I know that is what happens for me.

Hi Alan Thanks for your interest... What do you mean by the "correct location" for the profile made by the ColorMunki?

Cheers

Allan's explanation makes sense to me assuming ColorMunki works the same in that regard as Spyder. Once you use ColorMunki to calibrate the monitor, one of the last steps if not the last step in the ColorMunki process is to save the profile. It should automatically save it in the proper location on your computer without you having to know where it is saved. Just continue using your computer as usual.

When the time comes that you need to reboot your computer, the operating system should automatically find the saved profile and load it. If ColorMunki's software works the same as Spyder's software, a message will be automatically displayed indicating that the profile has been successfully loaded. If you're closely watching your monitor at the time it is loaded, any change the profile makes to your system will be noticeable unless the change is so slight that you can't see the difference between the uncalibrated monitor and the calibrated monitor.

Hope that helps! As a reminder, I use Spyder rather than ColorMunki. I posted this information only so you wouldn't have to wait longer than you already have for a helpful response. It would be ideal if a ColorMunki user would confirm this information.

Thanks Mike.. My process using the ColorMunki went fine and it did save it... My concern is that this is a windows problem and I am just having difficulty getting it to default to the profile that I wish to be used for the monitor. I can , as I said , apply the profile each time that I start up but its just a niggle..

Sorry, Bernard, but I'm no help with your Windows issue.

Have a look in your start up progs. Maybe you'll find something there.

Bernard,

This may be what you are looking to locate....................

Although taken from my Win 10 system, colour management settings, it's the same as what was in my Win 7. This is the location where my monitor profiles are put after calibration and note at the top the box for selecting 'use my settings for this device'.

Hi Bernard

I assume your problem is that Windows is not holding the default setting against your preferred profile. This thread here deals with this issue in Windows 7, particularly the last 5 posts on page 2. It seems you are not alone. It might be related to some of the special utilities installed by certain pc suppliers, I don't know. The program called Color Profile Keeper mentioned in the last post might do the trick.

Hi Dave... sorted ... took a little while for me to get it right but it's all done now and OK.. the monitor is now being held to the ICC profile. Once again thanks to all of you for taking the time to help on this ...

Just to be clear on this, a monitor profile is used for two quite different purposes.

First, it is used for colour managed programs (and only colour managed programs) to tell them the colour space of the monitor, to allow the programs to map colours from the image's colour space to the monitor's colour space. You can check this by looking in Control Panel -> Colour Management. As Stagecoach showed above, this will show the current profile; this is the one with "(default)" after the name, and should correspond to the last one you created with your ColorMunki software.

Second, it is used contain the calibration information, which is loaded into the Video Card's "Video Card Gamma Tables". This causes the monitor's white point and tone curve to be adjusted for all programs, including the Windows desktop (which isn't colour managed). The calibration data is loaded into the VCGTs at boot up. There should be in start menu -> Start-up an entry for something like "ColorMunki Display Tray". This program is what loads the VCGTs. If there isn't a start-up entry then the VCGTs may not get loaded, even if the right profile is shown in Control Panel. If that entry isn't there you should be able to create it by reinstalling the ColorMunki software.

Yes not sure about Colormunki but with Spyder, a small banner comes up shortly after boot up indicating that data has been loaded into the video card. It only lasts a few seconds so you have to be on the lookout to see it. This is a good indication that all is well with the lut loader.

Never seen such a banner with ColorMunki. At what stage does it appear?

Dave there is a Datacolor Spyder start up utility which loads the lut and presumably displays the banner. It is at the end of the Windows startup phase and only lasts a few seconds. I don't know whether XRite has a similar display or not.

The window Dave mentions that is displayed by the Spyder software also indicates that the profile is not loaded if indeed that's the case. It happened to me only once in years of using two or three versions of the product but it did happen.

Once the profile has been made and written away in the right place and been set as default, you don't need the software anymore. Unless you want to make use of something as ambient light corrections.

George we are not talking about the main Datacolor software that is used to produce a profile but rather a small piece of software that comes with the Datacolor product called SpyderUtility. It is mainly used to load lut gamma data into the video card. This is done every time the computer is rebooted.

In my startup there was a utility called Spyder3Utility.lnk. I had it disabled. I believe windows itself should take care for the loading of the icc profile. Like in the example of Graham. But what I don't get yet in his example is that there are some profiles associated with his device, but no one selected. I can't compare with my screen for I only have 1 profile.

I must say Spyder didn't change the settings, I had to do it manual. Probably due to an old Spyder3 and Win 8.1

George Windows makes the default icc profile available to the software's color management system. (As indicated in Simon's post 11 above). The SpyderUtility takes care of the second part of the process as mentioned in Simon's post. ie it loads the gamma look up table into the video card. These are two separate processes. The gamma lut is saved in the icc file in the vcgt tag but this is a Private tag, and is not mentioned in the icc specs. It is not used for the actual color management process but rather the calibration of the monitor/video card.

Thanks. I missed this.
