MacBook Pro - resetting external display refresh rates

So I've been using Sun Displays as a second display above my MBP display while I'm in the office or at home and its been working pretty well.... but ;)

Today in the office I was playing around with the sync frequencies for the monitor (I run non-mirrored 1280x1024 over 1680x1050) and I got the crt accidentally set for a freqency it couldn't handle.

There was no way that I found that I could undo the setting manually.

Until I googled a post that mentioned blowing away the windowserver.plist.

I found I had to delete both plists and reboot to get it to work.

The files are:

  • Library/Preferences/com.apple.windowserver.plist
  • /Users/YOURUSERNAMEHERE/Library/Preferences/ByHost/com.apple.windowserver.SOMENUMBERHERE.plist
