Screen colour temperature changes (bluer) when running web video, iDVD

An odd intermittent issue I noticed since upgrade from Lion to Mountain Lion.


Noticed on MacBook Pro 15" (high resolution), Early 2011 (MacBookPro8,2).


When I launch iDVD the screen turns brighter and a more blue-ish hue. It reverts when I close iDVD.


Issue is not isolatied to iDVD, for example it also occurs when running BBC Olympics web video content:

Anyone know the cause or have a workaround? Driving me crazy!

MacBook Pro (15-inch Early 2011), OS X Mountain Lion

go to color sync utility and run the verify and repair color profile thing in "Profile first aid" in, again, Color Sync Utility (in the utilities folder in the applications folder).

Looks like you probably found the issue, thanks.. but i get the following errors when running Repair...


Searching for profiles...

Checking 28 profiles...

/System/Library/CoreServices/Resources/Profiles/HD 709-A.icc

Header message digest (MD5) is missing.

The file is locked. Could not be fixed.

/System/Library/CoreServices/Resources/Profiles/SD 170M-A.icc

Header message digest (MD5) is missing.

The file is locked. Could not be fixed.

Repair done - 0 out of 2 profiles fixed.



I rebooted and retried without launching anyt other apps but same issue.... Any ideas what could be locking the colour profiles?

In ColorSync Utility I went to 'Devices', selected Displays -> Color LCD


I noticed Current Profile showed 'Display', whereas Factory Profile said 'Color LCD'.


I changed Current Profile to 'Color LCD' and now Profile First Aid Verify passes -- without need for Repair.


Looks like that cracked it. Thanks for pointing me to ColorSync utility. 🙂

eh,


to tell you the truth, i have this issue and googling hasn't given me any insight how to get it not to happen but it occurs sometimes with external monitors or something but I have a late 08 MBP and only have read reports of it happening on my model.


The fix, is to sleep and wake the computer,


but you could try a PRAM reset to see if it fixes yours

Preventing the MacBook from dynamically switching from integrated (not blue) to discrete (blue) is not really suitable for me. What is posted in above links are only workarounds that limit the functionailty of my device. I want to use the features of my Mac as intended by Apple to preserve battery life. I want both display drivers to show the same colour.


PRAM reset never worked for me.


Booting Mac, logging in then off and on again is also a workaround -- I think mentioned here somewhere previously. This is a major pain though, as you can imagine.


Thanks for drawing my attention to display mode switching as being the potential cause however.
