Strange monitor behavior

[mdijb]

I have an old Apple cinema display I use as my second monitor.  For some unknown reason, the colors now appearing are the opposite of what they should be, and effects everything.

I have no clue what changed.  How can I fix this?

Probably a broken video card. Needs replacement.

Delete the display profile, create a new one. help?

I recalibrated and the colors were normal, but only for a short time,  then the color reversal ocurred again.  When I went to an older profile, the colors returned to normal.

Sounds like something is hosing the profile. Do some disk checking (file permissions and the like).
Might try finding the profile that works, locking it? Not sure if that will do the trick. But something is screwing with that profile. Maybe next time you build one, duplicate it then replace and see what happens. What software are you using to build the profile?

I used the Xrite Color munki.

On hte mac using El capitan, You nolonger can do a permissions repir--they took that capability out of the disk Utility

Control-Option-Command-8 key combo

or now System Preferences->Accessibility->Display; Invert Colors ?

How to Repair Verify Disk Permissions in OS X El Capitan
Open the Terminal application (found in /Applications/Utilities/) and use the following syntax to verify a volumes permissions, this will verify the default root volume of a Mac:


sudo /usr/libexec/repair_packages --verify --standard-pkgs /


If you want to verify permissions on a different drive, specify the volume rather than “/”


Can't hurt to run the Disk First Aid too.
Also a good fix is to Reboot in Safe Mode (hold down Shift Key when rebooting). Then reboot normally. Lots of house cleaning going on when you do a Safe Mode boot.  Verifies your startup disk, and attempts to repair directory issues if needed

I did the Restart in safe mode routine and the DIsk firstaid. No change the blue folders are still orange on my desktop

But this reverts to normal after recalibration and a new profile?

OK.  I recalibrated again the monitor and the colors look OK and and holding
