Changing the Monitor Screen Resolution
For most installations, the Sun XVR-500 graphics accelerator automatically
configures itself to the proper screen resolution and refresh rate for your monitor. If
a Sun monitor, however, is not connected to the Sun XVR-500 graphics accelerator,
the monitor may have the wrong screen resolution. To change the screen resolution,
use the
fbconfig
utility.
