The Utility submenu contains the following functions:

Navigation Buttons Menu Item Explanation

This selection is used to “capture” the image content currently

being displayed. Updates of the display based on subsequent

signal changes at the video inputs are temporarily halted. This

control could be useful, for example, in conjunction with a Print

Screen operation.

Reset

Select with caution. All controls will be returned to factory

default settings and any remembered settings for specific

formats will be erased.

Color

Temperature

Color temperature corresponds to a particular balance of the

red, green and blue components of white. When the color

temperature is increased, the blue component becomes more

prominent. When the color temperature is decreased, the red

component becomes more prominent. Best performance of

an LCD is generally obtained when the color temperature is

set to about 5600°K. This provides a white with more red than

the white commonly obtained with a CRT (9300°K).

Use the UP or DOWN button to select the desired function.

Use the LEFT or RIGHT button to set the value of the selected

function. Use the SOURCE button once a setting has been made, and

again to return to the Main Menu.

Freeze Frame

Info

Select this item to obtain a display of information about the

current video source, including horizontal frequency, vertical

frequency (refresh rate), etc. There are no settings to make.

Utility Submenu

NOTE:

When no video signal is applied to any of the monitor’s video inputs, the OSD will present the

following message: “No input signal.” This message will remain on display for the OSD

timeout period; then the monitor will go into a Sleep Mode. Sleep Mode is a reduced power

mode in which the backlights are turned off. The monitor continues to monitor the video

inputs. If it detects signals from an external source, it “wakes up” in order to be able to display

the image.

When no signals from an external source are present and the monitor is in Sleep Mode,

access to the OSD controls is limited. In this case, only the AUTO and SOURCE buttons are

useful. When the AUTO button is pressed, the effect is to awaken the monitor manually. If

there are no signals at the monitor’s inputs, the “No input signal” message will again be

presented and the monitor will then return to sleep. When the SOURCE button is pressed, the

monitor will likewise wake up, scan its inputs and present a message about what it found

before returning to sleep.
