Setting Up the Monitor
To set up the monitor, ensure that the power is turned off to the
monitor, computer system, and other attached devices, then
follow these steps:
1. Place the monitor in a convenient, well-ventilated location
near your computer.
2. Connect the monitor signal cable 1 to the 15-pin connector
on the rear panel of the computer and tighten the screws.
Be sure the signal cable aligns with the 15-pin connector. Do not

USB Connectors
The base of the monitor has two Universal Serial Bus (USB)
connectors. Use connector ❶ to connect the USB signal cable
to the computer. Use connector ❷ to connect USB compatible
plug and play devices such as a keyboard, mouse, or joystick if
supported by your computer. This feature provides USB passthrough and does not support USB host requirements.

Adjusting the Monitor Screen
Optimizing Contrast
Optimizing Focus
Allow the monitor to warm up for 30 minutes before
performing the following procedures. The screen image
stabilizes after a warm-up period.
For best results, set your screen to a dark background (such as
the DOS prompt) before adjusting the following settings:
1. Set the brightness and contrast controls to their lowest
settings.
2. Increase brightness until the background portions of the
screen are visible, then slowly reduce brightness until the
background is just extinguished.
3. Adjust contrast control to your preference.
The default image size is preset at the factory. The Horizontal
and Vertical Size and Position controls located on the front
control panel can be used to increase the screen size beyond the
default setting. However, increasing the screen image beyond
the default settings may degrade the focus at the outer edge of
the screen.
To enhance focus, use the lowest brightness level that gives
satisfactory results in your viewing environment.

Display Resolutions Default Settings
User Modes
The resolution settings listed below are the most commonly
used modes and are set as factory defaults. The monitor
automatically recognizes these preset modes as they are
requested by a software program.

10. Macintosh Display Mode 832 × 624 at 49.72 kHz/74.5 Hz
The video controller signal may occasionally call for a mode
that is not preset if:
■ You are not using a compatible Compaq graphics adapter.
■ You are not using a preset mode.
1-10 English
If this occurs, you may need to readjust the parameters of the
monitor screen by using the controls on the front panel. The
monitor automatically stores the new setting, then automatically
recognizes the new mode just as it does a preset mode. In
addition to the 10 preset modes that can be changed and stored,
there are 4 user modes that can be entered and stored. When the
4 user mode settings are exceeded, the newest setting will
replace the setting closest to its own setting.
To revert back to the factory default settings, select Reset using
the dual control adjustments for the front panel controls, and the
factory default resolutions will replace the current operating
mode with the original or factory default display mode.
Energy Saver
Feature
The energy saver feature has three different modes of
operation:
■ Full power mode
■ Suspend mode
■ Sleep mode
By selecting settings in the computer's Energy Saver utility, you
determine the length of inactivity before the monitor goes into
suspend or sleep mode.
The following table describes the monitor energy saver levels
available during the different modes of operation.

Care and Maintenance
Protecting the Monitor
This section explains how to care for and maintain your
Compaq monitor during normal everyday use.
To protect your monitor from overheating and other types of
damage, follow these suggestions:
■ Use only a power source and connection appropriate for
this monitor, as indicated on the marking label/back plate.
■ If an extension cord or power strip is used, make sure that
the cord or strip is rated for the product and that the total
ampere ratings of all products plugged into the extension
cord or power strip do not exceed 80% of the extension cord
or strip ampere ratings limit.
■ Do not overload an electrical outlet, power strip, or
convenience receptacle. The overall system load must not
exceed 80% of the branch circuit rating. If power strips are
used, the load should not exceed 80% of the power strip
input rating.
■ Install the monitor near an outlet that you can easily reach.
Disconnect the product by grasping the plug firmly and
pulling it from the outlet. Never disconnect it by pulling the
cord.
