Displays preference pane not working?

Question

I am on a new MacPro 2.66 Dual running 10.4.8 with a brand spankin' new
20" NEC MultiSync LCD 2070NX display. I am trying to calibrate my monitor so I can get back to one of my daily duties - color correction. I have the NEC display software installed which is very limited. I can adjust brightness, contrast, or use an already predetermined color profile. Not acceptable in my
professional opinion so I would love to use Apples display preferences to fine-tune my own profile.
When I click on the displays pane I get the following message - "You cannot open Displays preferences pane on this computer. Contact the developer of this software for a newer version."
I find this ironic because I am on the newest OS, I tried NEC support and they told me it's an Apple issue. I know I should have purchased an Apple LCD but at the deal I got on the NEC I couldn't pass it up. The reviews in MacWorld for the NEC were great as well as Amazon. Been through the forumns and googled what I could but to no avail my displays pane is still inoperable.
Ideas anyone?

Answer 1

You can try reinstalling the Displays preference pane. Download the shareware utility Pacifist and use it to extract a fresh copy from the file archives on the Tiger DVD. The archives are in the /System/Installations/ folder.
I would also suggest the following:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
