Changing monitor settings
To get the best possible image on your screen and to reduce flicker, you
might need to reset the resolution and refresh rate of your monitor. You
can view and change monitor settings through your operating system using
the instructions provided in the README files on the Software Selections CD
that comes with your computer. Refer to your operating system
documentation for further information on monitor settings.
Attention
Before you change any monitor settings, be sure to review the
information that comes with your monitor. Using a resolution or
refresh rate that is not supported by your monitor might cause the
screen to become unreadable and could damage the monitor. The
information that comes with your monitor usually includes the
resolutions and refresh rates that the monitor supports. If you need
additional information, contact the manufacturer of the monitor.
To minimize screen flicker and jitter, set your monitor for the highest
noninterlaced refresh rate that the monitor supports. If your monitor
complies with the VESA Display Data Channel (DDC) standard, it is
probably already set to the highest refresh rate that the monitor and video
controller can support. If you are not sure if your monitor is
DDC-compliant, refer to the documentation provided with the monitor.
Using audio features
Some models have an integrated Analog Devices, Inc. audio controller that
supports Sound Blaster applications and is compatible with the Microsoft
Windows Sound System. These models also have a single internal speaker
and three audio connectors. The audio controller provides you with the
ability to record and play back sound and music and to enjoy sound with
multimedia applications. Optionally, you can connect two stereo speakers
to the line out connector to enjoy better sound with multimedia
applications.
The audio connectors in your computer are 3.5 mm (1/8-in.) mini-jacks. A
description of the connectors follows. (For the location of the connectors,
refer to “Connecting computer cables” on page 10.)
Line/Headphone Out: This jack is used to send audio signals from the
computer to external devices, such as stereo-powered speakers
with built-in amplifiers, headphones, multimedia keyboards, or
the Audio Line-In jack on a stereo system.
