If you are using a cathode ray tube (CRT) monitor, set your monitor for the highest
noninterlaced refresh rate that the monitor supports. If your 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 your 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

Your computer has an integrated audio controller that supports Sound Blaster
applications and is compatible with the Microsoft Windows Sound System. Your
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 your computer are 3.5 mm (0.125-in.) mini-jacks. For the
location of the audio connectors, see "Input/output connectors" on page 49.
