Sun XVR-600 Graphics Accelerator
Framelock System
The framelock synchronization feature enables vertical retracing to occur
simultaneously on each Sun XVR-600 graphics accelerator subsystem. The framelock
cable assembly is used to daisy-chain two or more Sun XVR-600 graphics accelerator
subsystems. Vertical retrace synchronization eliminates flicker between multiscreen
displays.
Framelocking is often necessary when running in stereo in a multihead environment.
All the displays can be synchronized so that the left and right views can be seen
correctly through one set of LCD stereo glasses.
When frame buffers are framelocked, you should make sure they are all running at
the same video resolution and vertical retrace rate (see fbconfig -help for details).
See “Configuring Sun XVR-600 Graphics Accelerators for Framelocking” on page 36.
To use the framelock features, the framelock cable assembly is required. See
“Framelock Cable Assembly” on page 38 for installation.
