Video device drivers To use the full capabilities of the graphics adapter in the computer, some operating systems and application programs require custom video device drivers. These device drivers provide greater speed, higher resolution, more available colors, and flicker-free images. Device drivers for the graphics adapter and a readme file with instructions for installing the device drivers are provided on the Device Drivers CD that comes with the computer and in the c:\ibmtools\drivers directory on the hard disk. Use the device-driver installation instructions if you have to reinstall the device drivers or if you need information about obtaining and installing updated device drivers. For more information about installing device drivers, see the Problem Determination and Service Guide. Changing monitor settings To get the best possible image on the screen and to reduce flicker, you might have to reset the resolution and refresh rate of the monitor. You can view and change monitor settings through the operating system by following the instructions in the readme files on the Device Drivers CD or in the c:\ibmtools\drivers\ directory on the hard disk. See the operating-system documentation for more information about monitor settings. Attention: Before changing monitor settings, review the documentation that comes with the monitor. Using a resolution or refresh rate that the monitor does not support might cause the screen to become unreadable and could damage the monitor. The information that comes with the monitor usually includes resolution and screen refresh rates that the monitor supports. If you need additional information, contact the manufacturer of the monitor. If you are using a cathode ray tube (CRT) monitor, set the monitor for the highest noninterlaced refresh rate that the monitor supports. If the monitor complies with the Video Electronics Standards Association (VESA) display data channel (DDC) standard, it is probably already set to the highest refresh rate the monitor and video controller can support. If you are not sure whether the monitor is DDC-compliant, see the documentation that comes with the monitor. If you are using a flat-panel monitor, the refresh rate does not have to be set to the highest noninterlaced refresh rate that the monitor supports. Flat-panel monitors produce flicker-free images even when they are operating at a minimum 60 Hz noninterlaced rate. If you have a dual-monitor video adapter, see the video adapter device-driver readme file and documentation for more information about enabling dual monitors. Using audio features The computer has an integrated audio controller that supports Sound Blaster applications. The computer also has a single internal speaker and three types of audio connectors. Using the audio controller, you can record and play back sound and music to enhance multimedia applications. Optionally, you can connect external speakers to the line-out connector to provide improved sound with multimedia applications. The audio connectors in the computer are 3.5 mm (0.125-in.) mini-jacks. For the location of the audio connectors, see "Input/output connectors" on page 60. Chapter 2. Operating the computer 15

Video
device
drivers
To
use
the
full
capabilities
of
the
graphics
adapter
in
the
computer,
some
operating
systems
and
application
programs
require
custom
video
device
drivers.
These
device
drivers
provide
greater
speed,
higher
resolution,
more
available
colors,
and
flicker-free
images.
Device
drivers
for
the
graphics
adapter
and
a
readme
file
with
instructions
for
installing
the
device
drivers
are
provided
on
the
Device
Drivers
CD
that
comes
with
the
computer
and
in
the
c:\ibmtools\drivers
directory
on
the
hard
disk.
Use
the
device-driver
installation
instructions
if
you
have
to
reinstall
the
device
drivers
or
if
you
need
information
about
obtaining
and
installing
updated
device
drivers.
For
more
information
about
installing
device
drivers,
see
the
Problem
Determination
and
Service
Guide
.
Changing
monitor
settings
To
get
the
best
possible
image
on
the
screen
and
to
reduce
flicker,
you
might
have
to
reset
the
resolution
and
refresh
rate
of
the
monitor.
You
can
view
and
change
monitor
settings
through
the
operating
system
by
following
the
instructions
in
the
readme
files
on
the
Device
Drivers
CD
or
in
the
c:\ibmtools\drivers\
directory
on
the
hard
disk.
See
the
operating-system
documentation
for
more
information
about
monitor
settings.
Attention:
Before
changing
monitor
settings,
review
the
documentation
that
comes
with
the
monitor.
Using
a
resolution
or
refresh
rate
that
the
monitor
does
not
support
might
cause
the
screen
to
become
unreadable
and
could
damage
the
monitor.
The
information
that
comes
with
the
monitor
usually
includes
resolution
and
screen
refresh
rates
that
the
monitor
supports.
If
you
need
additional
information,
contact
the
manufacturer
of
the
monitor.
If
you
are
using
a
cathode
ray
tube
(CRT)
monitor,
set
the
monitor
for
the
highest
noninterlaced
refresh
rate
that
the
monitor
supports.
If
the
monitor
complies
with
the
Video
Electronics
Standards
Association
(VESA)
display
data
channel
(DDC)
standard,
it
is
probably
already
set
to
the
highest
refresh
rate
the
monitor
and
video
controller
can
support.
If
you
are
not
sure
whether
the
monitor
is
DDC-compliant,
see
the
documentation
that
comes
with
the
monitor.
If
you
are
using
a
flat-panel
monitor,
the
refresh
rate
does
not
have
to
be
set
to
the
highest
noninterlaced
refresh
rate
that
the
monitor
supports.
Flat-panel
monitors
produce
flicker-free
images
even
when
they
are
operating
at
a
minimum
60
Hz
noninterlaced
rate.
If
you
have
a
dual-monitor
video
adapter,
see
the
video
adapter
device-driver
readme
file
and
documentation
for
more
information
about
enabling
dual
monitors.
Using
audio
features
The
computer
has
an
integrated
audio
controller
that
supports
Sound
Blaster
applications.
The
computer
also
has
a
single
internal
speaker
and
three
types
of
audio
connectors.
Using
the
audio
controller,
you
can
record
and
play
back
sound
and
music
to
enhance
multimedia
applications.
Optionally,
you
can
connect
external
speakers
to
the
line-out
connector
to
provide
improved
sound
with
multimedia
applications.
The
audio
connectors
in
the
computer
are
3.5
mm
(0.125-in.)
mini-jacks.
For
the
location
of
the
audio
connectors,
see
“Input/output
connectors”
on
