Software controls
Adjusting the color depth and screen resolution are two of the most basic
display settings you may need to change.
Adjusting the color depth
Color depth is the number of colors your flat panel display uses. Different image
types require various color depths for optimum appearance on your flat panel
display. For example, simple color drawings may appear adequately in 256
colors while color photographs need millions of colors to be displayed with
optimum quality.
Windows lets you choose from several color depth settings for your flat panel
display. We recommend that the 32-bit True Color setting be used at all times.
If the color in your images seems “false” or “jumpy,” especially after you have
played a game or run a video-intensive program, check the color depth setting
and return it to 32-bit True Color, if necessary.
Help and
Support

Power management
ENERGY STAR
As an ENERGY STAR® Partner, Gateway has determined that this product
meets the ENERGY STAR guidelines for energy efficiency.
This monitor complies with the EPA's International ENERGY STAR Program,
which is a program designed to encourage manufacturers of computer
equipment to build circuitry into their products to reduce energy
consumption during time of non-use.
Energy declaration
When connected to a computer that supports the VESA Display Power
Management Signaling (DPMS) Protocol, this monitor can conserve
significant energy by reducing power consumption during periods of non-use.
When the computer goes into the energy saving mode, the monitor will then
enter the Active Off mode (different from total shut down). In the Active Off
mode the Power LED will still show amber.
By following these conventions the power can be reduced to the following
levels:
To “wake” the monitor when it is in Active Off mode, move your mouse or
press any keyboard key.
You can change the period of time after which the monitor enters these low
power states by accessing the power management options in the Control
Panel.

■Some products are equipped with a three-wire power cord to make sure that the product is
properly grounded when in use. The plug on this cord will only fit into a grounding-type
outlet. This is a safety feature. If you are unable to insert the plug into an outlet, contact an
electrician to install the appropriate outlet.
■If you use an extension cord with this system, make sure that the total ampere rating on the
products plugged into the extension cord does not exceed the extension cord ampere rating.
■If your system is fitted with a TV Tuner, cable, or satellite receiver card, make sure that the
antenna or cable system is electrically grounded to provide some protection against voltage
surges and buildup of static charges.
Care during use
■Do not walk on the power cord or allow anything to rest on it.
■Do not spill anything on the system. The best way to avoid spills is to avoid eating and
drinking near your system.
■When the monitor is turned off, a small amount of electrical current still flows through the
monitor. To avoid electrical shock, always unplug all power cables and modem cables from the
wall outlets before cleaning the system.
■Unplug the system from the wall outlet and refer servicing to qualified personnel if:
■The power cord or plug is damaged.
■Liquid has been spilled into the system.
■The system does not operate properly when the operating instructions are followed.
■The system was dropped or the cabinet is damaged.
■The system performance changes.
Replacement parts and accessories
Use only replacement parts and accessories recommended by Gateway.
Warning To prevent electric shock, never remove the cover. No user
serviceable parts inside. Refer servicing to qualified
service personnel.
Important Do not use Gateway products in areas classified as
hazardous locations. Such areas include patient care
areas of medical and dental facilities, oxygen-laden
environments, or industrial facilities.
