the display brightness key combinations, the ALS is disabled and the display brightness is increased or
decreased accordingly.
Dell™ QuickSet allows you to enable or disable the ALS feature. You can also adjust maximum and
minimum brightness settings that are activated when you enable the ALS feature. For more information
about QuickSet, right-click the icon in the taskbar, and click Help.
NOTE: Rebooting the computer returns the ambient light sensor to the last setting of enabled or disabled.

control the brightness on any external monitors or projectors.
Using ATI Catalyst
®
Control Center
The ATI Catalyst Control Center is a graphical user application that provides access to display features
contained within the installed ATI hardware and software. The Catalyst Control Center fine-tunes your
graphics settings, enables or disables connected display devices, and changes the orientation of your
desktop. Many of the features show you a preview of the changes before they are applied.
NOTE: Microsoft .NET 1.1 or 2.0 must be installed to support the full functionality of the Catalyst Control Center.
The Catalyst Control Center provides two views of the software:
• Standard View is a simplified view that includes wizards to get the inexperienced user up and running.
• Advance View allows the advanced user to access and configure the complete feature set of the
software.
The Catalyst Control Center can be customized for easy access to the features you use most.
Use the Catalyst Control Center to access a comprehensive online help system, or connect to the ATI
web site.
