IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry



SYMPTOMS
If the 3D Maze screen saver is configured with a timeout value that is greater than that of the &quot;turn off monitor&quot; Power Options setting, when the 3D Maze screen saver starts, power may be restored to the monitor.



CAUSE
With the OpenGL 3D Maze screen saver, you can configure the screen size. To do so, the screen saver calls the Win32 ChangeDisplaySettings API. If the display settings are changed, power is restored to the monitor.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

The 3D Maze screen saver has a number of settings you can control, including screen size. Most of these are available by clicking the Settings button on the Screen Saver tab of the Display Properties dialog box, but you cannot configure the TurboMode setting with the Settings button. If TurboMode is set to 0, the display attributes are not changed, and this allows the screen saver to start without restoring power to the monitor. To set TurboMode:  Use Registry Editor (Regedt32.exe) to locate and then click the following key in the registry:

HKEY_CURRENT_USER\Control Panel\Screen Saver.3DMaze

 On the Edit menu, click Add Value, and then add the following registry value:

Value name: TurboMode

Data type: REG_SZ

Value data: 1

 Quit Registry Editor.

With TurboMode set to 0, the 3D Maze screen saver does not call ChangeDisplaySettings. This has the side effect of not restoring power to a monitor which Power management has put into Standby mode.
