Description
Determines whether users can save changes to the display settings of graphics devices. The display settings, which can be changed by using Display in Control Panel, include resolution, color depth, and refresh rate. This entry is less restrictive than DisableAll in the TemporarySettingChanges subkey, which provides a way to change display settings, but not to save these changes.
Value |
Meaning |
---|---|
0 |
All users can save the changes they make to display settings. |
1 |
No users, including the Administrator, can save changes made to display settings. |
Note
Windows 2000 does not add this entry to the registry. You can add it to override the default configuration of graphics drivers by editing the registry or by using a program that edits the registry.
Setting DisableAll to 1 is more restrictive than disabling Display in Control Panel (NoDispCPL). DisableAll prevents the use of the ChangeDisplaySettings API. Disabling Display in Control Panel does not prevent the user from using other programs that call the ChangeDisplaySettings API.
