Changing the Video Configuration 65Changing the Video ConfigurationYour computer includes a TFT LCD or active-matrix display. The capabilities of the screen plus the video drivers installed on the computer determine the quality of the image your LCD can display.The following sections describe the display capabilities of your computer.Resolution and Color DepthThe resolution of the LCD is the sharpness of the image it can display. Resolution is measured by the number of pixels (individual dots) displayed on the entire screen. In general, the more pixels the LCD can display, the better the image. Your LCD screen is either SVGA or XGA:•The maximum display for the SVGA LCD screen is 800x600, about 480,000 pixels. •The maximum display for the XGA LCD screen is 1024x768, about 800,000 pixels. The number of colors the LCD can display is measured by how many bits the LCD uses to represent each pixel:•8-bit color can support 256 different colors. •16-bit color can support 64 K (65,536) colors. •24-bit color can support 16 M (16.8 million) colors. •32-bit color can support 16 M (16.8 million) colors. 24-bit color uses the RGB color model.32-bit color uses the CMYK color model which gives better printed color matching. Table 8 lists the basic video mode capabilities and maximum colors supported by your computer.

About Drivers and System Resources 77About Drivers and System ResourcesThis section gives you basic information about drivers and system IRQs.DriversA driver is a program that enables the operating system to work with a hardware device. Your computer includes drivers for the audio, video, infrared, touchpad, keyboard, CD-ROM drive, hard drive, floppy drive, and PC Card controller. When you add a device to your computer, such as a printer, you install a driver for that device. Different drivers are used by different operating systems.IRQsMost of the devices in your computer or connected to your computer need their own IRQ (interrupt request line). The IRQ is a hardware line that a device can use to send signals to the microprocessor. When the device needs the microprocessor’s service, the device sends an interrupt request signal to the microprocessor.The number of IRQs available for any computer is limited by industry standards. Because it ships with numerous features, this computer uses most of the available IRQs. If you add another device to your computer, you may need to disable an existing device to free up an IRQ for the new device. IRQ resources are of particular concern when the computer is attached to a docking device.The default IRQ settings that are used by your computer are listed in Table 9 and Table 10.Table 9.

About Drivers and System Resources 79In Windows 98, you can configure a device so that the device is disabled when you connect your computer to a docking station but enabled when the computer is not connected to the docking station. With this configuration, an IRQ is available for a peripheral device that you connect to the docking station. See your Windows 98 manual for more information.
