The Power Mac G5 computer provides video output at picture sizes and frame rates compatible with the NTSC

and PAL standards; the picture sizes are listed in Table 3-13 (page 56). Those picture sizes produce

under-scanned displays on standard monitors.

Dual Display Extended and Mirror Modes

The Power Mac G5 is equipped with two graphics ports. The Power Mac G5 can support dual displays in both

extended desktop and video mirroring modes. Extended desktop mode lets users distribute work across two

displays, increasing the amount of visible desktop space. Video mirroring mode displays the same information

on both monitors, enabling the control of a presentation on one display, while allowing an audience to watch

the presentation on a second display or projector. The NVIDIA GeForce 6800 Ultra DDL graphics card can power

two Apple Cinema HD Displays.

To switch between extended desktop and video mirroring modes, enable the “Mirror Displays” option on the

Arrangement tab in the Displays pane of System Preferences.

The scaling function is available when both monitors are operating and the mirror mode is selected. Either

monitor could have black borders during mirroring, depending on the supported timings between the two

displays and on the monitor’s selection algorithm. Both displays show full-sized images only when the resolutions

match. Both displays can operate with other resolution settings, but in mirror mode, one of them has a display

that is smaller than the full screen and has a black border around it.
