Appendix F Multiscreen Viewing 49
Configuring for Multiview
Multiview synchronization enables vertical retracing to occur simultaneously across
each Sun XVR-2500 graphics accelerator in the system. This feature is typically used
for stereo mode applications. Vertical retrace synchronization eliminates flicker
between multiscreen displays.
Caution – Power off the system before connecting the genlock ribbon cable when
configuring for multiview.
1. Connect the multiview genlock ribbon cable between both graphics boards.
a. Connect the top of the genlock ribbon cable to the multiview connector of the
first graphics board (
FIGURE F-2
) .
b. Connect the other end of the genlock ribbon cable to the multiview connector
of the second graphics board (
FIGURE F-2
) .
Note –
You can only configure for multiview after logging into the workstation
desktop. Multiview settings are not retained, therefore, you need to configure for
multiview each time you log in.
2. Make sure that both Sun graphics accelerators are running identical video
formats.
a. Check the resolution of each board by using the
fbconfig
command.
For example:
b. Change a resolution by using the
fbconfig
command.
You must configure each board separately (that is, for
kfb0
,
kfb1
, and so on).
For example:
c. Log out of the X window system, and then log back in for the resolutions to
take effect.
host% fbconfig -dev kfb0 -prconf
host% fbconfig -dev kfb0 -res SUNW_STEREO_1280x1024x96
host% fbconfig -dev kfb1 -res SUNW_STEREO_1280x1024x96
