User's Guide 4­7 Operating the Monitor Selecting Video Input Connectors The input connectors are: VGA connector (analog) DVI-D connector (digital) HDMI connector The monitor automatically determines which inputs have valid video signals, and displays the image. You can connect the VGA cable, the DVI-D cable, or both. If both cables are installed, the default input selection is DVI. The HDMI cable is in place of the DVI-D cable. The source of input can be switched using the Switch Video Input option in the OSD menu. Switching from a VGA to an HDMI input source may take several seconds. Identifying Monitor Conditions Special messages appear on the monitor screen for the following monitor conditions: Input Signal Out of Range -- Indicates the monitor does not support the video card's input signal because its resolution or refresh rate are set higher than the monitor supports. Change your video card settings to a lower resolution or refresh rate. Restart your computer for the new settings to take effect. Monitor Going to Sleep -- Indicates the screen display is entering a sleep mode. The monitor also supports a power-saver mode that is controlled by the computer. When the monitor is in the reduced-power state, the monitor screen is blank, the backlight is off, and the Power light is amber. When the monitor is "awakened, " a brief warm-up period occurs before the monitor returns to normal operating mode. The energy-saving reduced power state activates if the monitor does not detect either the horizontal sync signal or the vertical sync signal. The power-saver feature must be activated on your computer for this feature to work. Refer to your computer documentation for instructions on setting energy-saver features (sometimes called power-management features). NOTE: The energy-saver feature works only when the monitor is connected to computers that have energy-saver features.

By default, the ambient light sensor is on. Manually enable or disable the sensor using the Image Control main menu in the OSD. If you adjust the Quick View, Brightness, Contrast, or sRGB functions in the OSD, the light sensor will automatically be disabled.
