Flat-Panel Display

The PowerBook G4 17-inch computer has a built-in, wide-screen, 100 dpi, color flat-panel display with a resolution of 1440 by 900 pixels and measures 17 inches diagonally.

The display is backlit by a cold cathode fluorescent lamp (CCFL). The display uses TFT (thin-film transistor) technology for high contrast and fast response.

In addition to its native resolution (1440 by 900) the display also supports several non-native resolutions, as shown in Table 3-12. The graphics controller IC includes a scaling function that expands displays with those smaller resolutions to fill the screen.

The display’s native resolution, 1440 by 900, has an aspect ratio of 16:10. When selecting a picture resolution with an aspect ration of 4:3, the user can choose to have it displayed with square pixels and black margins on the sides, or with stretched pixels that fill the display from side to side. These options are shown in Table 3-12(page 44).
