Apple Power Macintosh 7300 series - PC Compatibility Card - Manual (Page 29)

Configuring monitors
To connect a monitor, see Chapter 1, “Connecting Monitors and Other
Equipment.”
In most cases, the Mac OS recognizes the monitor you’re using to display the
PC environment. The monitor type appears in the Monitor section of the PC
Setup control panel.
If the monitor you’re using to display the PC environment is not working
correctly, make sure you have connected the monitor according to the
instructions in Chapter 1, “Connecting Monitors and Other Equipment,” and
make sure you have installed and configured the video software as described
in Chapter 2, “Installing the PC Compatibility Card Software.” For additional
information on video settings, see Appendix E, “Configuring Video
Software,” and Chapter 5, “Troubleshooting.”
If a VGA monitor is not working correctly, also check whether your
VGA-to-Macintosh adapter is configurable and verify the correct settings.
