Chapter 4 - Video Features and Configuration
Your 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.

The 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 12.1 SVGA, with a maximum display of 800x600, 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 6 lists the basic video mode capabilities and maximum colors supported by
your computer.
