FOR MORE INFORMATION: To learn more about accessing the Display Properties window to configure multiple monitors, see "Control Panel" on page 44. For more detailed information about the Control Panel, see "Windows Basic" in Windows Help and Support: click Start or → Help and Support. Using the Ambient Light Sensor in Bright or LowLight Environments: NOTE: Your laptop computer may not have an ambient light sensor. NOTE: The ambient light sensor adjusts the display brightness on your laptop computer only. It does not control the brightness on external monitors or projectors. The ambient light sensor is located on the front of the computer display. The sensor detects available environmental light and automatically increases or decreases the display backlighting to compensate for low-light and high-light environments. 1 1 Ambient Light Sensor Monitors and Displays 53
