Selecting Video Input Connectors
The input connectors are:
• VGA connector (analog)
• DVI-D connector (digital) (Select Models)
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 source of input can be switched using the Input
Select option in the OSD menu.
Identifying Monitor Conditions
Special messages will appear on the monitor screen when identifying the following
• Monitor Status - When the monitor is powered on or when the input source signal
is changed, a Monitor Status message is displayed for five seconds. The message
shows which input is the current active signal, the status of the auto-switch source
setting (On or Off), the default source signal, the current preset display resolution,
and the recommended preset display resolution.
• Input Signal Out of Range - Change resolution setting to 1366 x 768 @ 60Hz
(18.5 in),1600 x 900 @ 60Hz (20 in),1920 x 1080 @ 60Hz (23 in). Indicates the
monitor does not support the input signal because the resolution and/or refresh
rate are set higher than the monitor supports.
• No Source Signal - Indicates the monitor is not receiving a video signal from the
PC on the monitor video input connector. Check to determine if the PC or input
signal source is off or in the power saving mode.
• Auto Adjustment in Progress - Indicates the auto-adjustment function is active.
• Monitor Going to Sleep - Indicates the screen display is entering a sleep mode.
• Check Video Cable - Indicates the video cable is not properly connected to the

• If the OSD is locked, press and hold the Menu button for 10 seconds to unlock
• If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock
• Power Button Lockout - Indicates the power button is locked. If the power button is
locked, the warning message Power Button Lockout displays.
• If the power button is locked, press and hold the power button for 10 seconds
to unlock the power button function.
• If the power button is unlocked, press and hold the power button for 10
seconds to lock out the power button function.

Adjusting Screen Quality
The auto adjustment feature automatically fine-tunes the image quality for display
size, position, clock, and phase each time a new video mode is displayed. For more
precise adjustments of VGA input, run the Auto Adjustment software on the CD. If you
want additional image quality improvement, use the Clock and Phase controls of the
monitor to fine tune the image. See "Optimizing Analog Video" in this chapter.
Optimizing Analog Video
Some monitors contain advanced circuitry that allow the monitor to function as a
standard analog monitor. Two controls in the OSD menu can be adjusted to improve
analog image performance:
Clock - Increase or decrease the value to minimize any vertical bars or stripes visible
on the screen background.
Phase - Increase or decrease the value to minimize video distortion or video jitter.
Use these controls only when the auto adjustment function does not provide a
satisfactory monitor image in analog mode. To obtain the best results:
1. Allow the monitor to warm up for 30 minutes before adjusting.
2. Access the OSD menu, then select Image Setup.
3. Set the main Clock settings correctly first, because the Phase settings depend on
the main Clock settings.When adjusting the Clock and Phase values, if the
monitor images become distorted,continue adjusting the values until the distortion
disappears. To restore the factory settings, access the OSD menu, select Factory
Reset , and then select Yes .
When the monitor is in normal operating mode, the Power light is blue and the monitor
uses the normal watts of power. For power usage, refer to "Technical Specification"
(Appendix B). 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. The monitor uses minimum
power. 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.

Sleep Timer Mode
The Sleep Timer mode is an energy-saving feature that enables you to set a time for
the monitor to power on and off at the same time every day. This also extends the life
of the backlight bulbs in the monitor. The Sleep Timer has five settings:
• Set Current Time
• Set Sleep Time
• Set On Time
• Timer: On/Off
• Sleep Now
To set the timer:
1. Press the Menu button on the monitor front panel to display the OSD Menu.
2. Scroll down and highlight Management.
3. Press the OK button to select Management.
4. Scroll down and highlight and select Sleep Timer > Set Current Time.
Note: You must set the current local time before you reset the time for Sleep Time or
On Time. Note that the time is displayed in a 24-hour clock format. For example, 1:15
p.m. is displayed as 13 hours 15 minutes.
A power failure or loss of power to the monitor will cause the timer to reset to 00:00. If
this occurs, you will need to reset the sleep timer mode.
5. Press the OK button once to enter the adjustment mode for hours.
6. Press the - (Minus) or + (Plus) button to adjust the hour.
7. Press the OK button again to enter the time for minutes.
8. Press the - (Minus) or + (Plus) button to adjust the minutes.
9. Press the OK button to lock in the time chosen.
10. After setting the current time, the highlight automatically skips to Set Sleep Time.
Repeat steps 6 through 9 to set Sleep Time.
11. If you do not want to set Sleep Time, press the OK button twice, then select Save
and Return to exit the menu.
12. After setting Sleep Time, the highlight automatically skips to Set On Time. Repeat
steps 6 through 9 to set On Time.
13. Set the Timer mode to On to activate the Sleep Timer settings.
14. When you are finished, select Save and Return to exit the menu.
The fifth selection, Sleep Now, turns the monitor backlights off immediately and stays
in sleep mode until the next On Time activates or a monitor button is pressed.
