Chapter 4. Operating the Monitor
Special messages will appear on the monitor screen when identifying the following
monitor conditions:
• Input Signal Out of Range.Indicates the monitor does not support the input signal
because the resolution and/or refresh rate are set higher than the monitor
supports.
• No 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 or input source signal is not the same
with OSD Input Select setting.
• Auto Adjustment in Progress - Indicates the auto-adjustment function is active.
• Monitor Going to Sleep - Indicates the screen display is entering a sleep mode.
• OSD Lock - The OSD can be enabled or disabled by pressing and holding the
Menu button while the monitor is off and then press power button to turn the
monitor on.
• If the OSD is locked, press and hold the Menu button while the monitor is off
and then press power button to turn the monitor on to unlock the OSD.
• If the OSD is unlocked, press and hold the Menu button while the monitor is
off and then press power button to turn the monitor on to lock the OSD.
• Dynamic Contrast Ratio On - Indicates that Dynamic Contrast Ratio has been
turned on. This occurs if Dynamic Contrast Ratio is turned on in the Luminance
OSD menu.
• Dynamic Contrast Ratio Off - Indicates that Dynamic Contrast Ratio has been
turned off. This occurs if Dynamic Contrast Ratio is turned off in the Luminance
OSD menu.
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.
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 .
