Re: Monitor Resolution Changes

see the following:

"Mac OS X Server: Monitors Preference Offers Only 640 x 480"
http://til.info.apple.com/techinfo.nsf/artnum/n24889

excerpt:

"From a command shell, as root, or when telnetted in as root
(you must first telnet in as a user who is a member of group
"wheel" and su to root in order to be root via telnet), issue this
command:

defaults write Preferences
NSEnableShowAllDisplayModes YES

This will cause the monitor preferences panel to display all
modes, after you restart the computer. This will remain in effect
until you reinstall, or until the defaults file generated is thrown
away.

The Blue and White Apple Studio Displays are unaffected by
this issue.

Important: The above command will cause all possible sync
frequencies and format options for your video controller to be
displayed in the Monitors settings panel--even if your display
might not support them. Selection of incompatible formats may
cause your display to become scrambled, or even fail to
synchronize at all, resulting in a black screen. Therefore, make
sure that your format is one supported by your monitor. New
settings will go into effect as soon as you log out.

Documentation on this system defaults feature is sketchy; the
best reference with examples can be found in the following
article:

Article 60126: "Mac OS X Server: Setting Preferences"

Also, you can learn a great deal about it conceptually by typing:

man defaults

Another useful and related command enables use of multiple
monitors under Mac OS X Server:

defaults write NSGlobalDomain
NSEnableMultipleMonitors YES

Article 60126 goes into more detail about this and an
assortment of other default settings.

Cheers,

Kevin
