Chapter 2 Setting Up the Monitor  
NOTE: To view information on the screen in portrait mode, you will need to install the Pivot Pro  
software included on the software and documentation CD. The position of the OSD menu can  
also be rotated to portrait mode. To rotate the OSD menu, access the OSD menu by pressing  
the Menu button on the front panel, select OSD Control, then select Rotate OSD.  
Turning on the Monitor  
1. Press the power button on the computer to turn it on.  
2. Press the power button on the front of the monitor to turn it on.  
CAUTION: Burn-in image damage may occur on monitors that display the same static image on  
screen for a prolonged period of time.* To avoid burn-in image damage on the monitor screen, you  
should always activate a screen saver application or turn off the monitor when it is not in use for a  
prolonged period of time. Image retention is a condition that may occur on all LCD screens. Monitors  
with a “burned-in image” are not covered under the HP warranty.  
* A prolonged period of time is 12 consecutive hours of non-use.  
NOTE: If pressing the power button has no effect, the Power Button Lockout feature may be  
enabled. To disable this feature, press and hold the monitor power button for 10 seconds.  
NOTE: You can disable the power LED in the OSD menu. Press the Menu button on the front of the  
monitor, then select Management > Bezel Power LED > Off.  
When the monitor is powered on, a Monitor Status message is displayed for five seconds. The  
message shows which input (DisplayPort, DVI, or VGA) is the current active signal, the status of the  
auto-switch source setting (On or Off; factory default is On), the default source signal (factory default  
is DisplayPort), the current preset display resolution, and the recommended preset display resolution.  
The monitor automatically scans the signal inputs for an active input and uses that input for the  
display. If two or more inputs are active, the monitor will display the default input source. If the default  
source is not one of the active inputs, then the monitor will display the highest ranking priority input in  
the following order: DisplayPort, DVI, then VGA. You can change the default source in the OSD by  
pressing the front panel menu button and selecting Source Control > Default Source.

Preset 2 not supported on LA2405x model.  
Entering User Modes  
The video controller signal may occasionally call for a mode that is not preset if:  
You are not using a standard graphics adapter.  
You are not using a preset mode.  
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen  
display. Your changes can be made to any or all of these modes and saved in memory. The monitor  
automatically stores the new setting, then recognized the new mode just as it does a preset mode. In  
addition to the factory preset modes, there are 15 (LA1905wg model), 20 (LA2205wg and LA22f  
models), or 25 (LA2405wg and LA2405x models) user modes that can be entered and stored.  
Energy Saver Feature  
The monitors support a reduced power state. The reduced power state will be entered into if the  
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon  
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and  
the power light is turned amber. When the monitor is in the reduced power state, the monitor will  
utilize less than 2 watts of power. There is a brief warm up period before the monitor will return to its  
normal operating mode.  
Refer to the computer manual for instructions on setting energy saver features (sometimes called  
power management features).  
NOTE: The above power saver feature only works when connected to computers that have energy  
saver features.  
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to  
enter into the reduced power state at a predetermined time. When the monitor's Energy Saver utility  
causes the monitor to enter the reduced power state, the power light blinks amber.
