Sun XVR-4000 Graphics Accelerator
Framelock System
The framelock synchronization feature enables vertical retracing to occur
simultaneously on each Sun XVR-4000 graphics accelerator subsystem. The
framelock cable is used to daisy-chain two or more Sun graphics accelerator
subsystems, such as Sun XVR-500, Sun XVR-1000, and Sun XVR-4000 graphics
accelerators. Vertical retrace synchronization eliminates flicker between multiscreen
displays. You can framelock two or more Sun XVR-500, Sun XVR-1000, and Sun
XVR-4000 graphics accelerator subsystems across one or more computer systems.
Framelocking is often necessary when running multiple stereo displays for the same
observer. All the displays must be synchronized so that the left and right views can
be seen correctly through one set of LCD stereo glasses.
