Operating the Monitor

User’s Guide 5–7

Selecting the Video Input Connectors

The two input connectors are:

■ VGA connector (analog)

■ DVI-D connector (digital) for 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 Switch Video Input option in the OSD menu.

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 input signal because the

resolution or refresh rate are set higher than the monitor supports.

Set the resolution and refresh rate to the value displayed. Restart your computer for the new settings to take effect.

■ Monitor Going to Sleep — Indicates the screen display is entering a sleep mode. The speakers are turned off

in sleep mode.

■ Check Video Cable — Indicates a video input cable is not properly connected to the computer or monitor.

■ OSD Lock-out — The OSD can be enabled or disabled by pressing and holding the Menu button on the front

panel for 10 seconds. If the OSD is locked, the warning message “OSD Lock-out” appears for 10 seconds.

❏ If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.

❏ If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.

■ No Input Signal — Indicates the monitor is not receiving a video signal from the computer on the monitor

video input connector(s). Check to see if the computer or input signal source is off or in the power-saver mode.

■ Auto Adjustment in Progress — Indicates the auto-adjustment function is active. See “Adjusting Screen

Quality” in this chapter.

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. See “Using the Auto-Adjustment Function” in this chapter.

If you want additional image-quality improvement, use the Clock and Clock Phase controls of the monitor to fine-tune

the image. See “Optimizing Analog Video” in this chapter.

Optimizing Analog Video

This monitor contains advanced circuitry that allows 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.

■ Clock 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 20 minutes before adjusting.

2. Display the adjustment-pattern application provided on the CD.

3. Access the OSD menu, then select Image Control.

4. Set the main Clock settings correctly first, because the Clock Phase settings depend on the main Clock setting.

❏ When adjusting the Clock and Clock 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.
