Using video features

Your computer has a super video graphics array (XGA) graphics controller. XGA is a standard for displaying text and graphics images on a monitor screen and supports a variety of video modes. Video modes are different combinations of resolution, refresh rate, and color.

Depending on the applications you use and your personal preferences, you might need to change the video mode.

To change the video mode:

1.From the Windows desktop, click Start.

2.Select Settings, and then click Control Panel.

3.Double-click Display.

4.Click Settings, make the necessary changes, and then click OK.

Video device drivers

To take full advantage of the graphics adapter in your computer, some operating systems and application programs require software, known as video device drivers. These device drivers provide support for 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 Product Recovery Program located on the hard disk drive.

If your computer has IBM-preinstalled software, video device drivers have already been installed on the hard disk. However, you can use the device driver installation instructions if you need to reinstall the device drivers or if you need information on obtaining and installing updated device drivers.

Using audio features

Your computer has a digital audio controller built into the system board. The system-board audio controller supports applications written for SoundMAX with SPX and are compatible with the Microsoft Windows Sound System. The audio connectors in your computer are 3.5 mm (1/8-in.) mini-jacks.

Controlling volume

You can control the volume through several different means:

•The software volume control is accessible through the speaker icon in the taskbar, which is located at the bottom-right corner of the Windows desktop.

—If you click the speaker icon one time, the volume control is displayed. Use your mouse to drag the volume-control slider up or down to control the volume, or select the Mute check box to turn the audio off.
