Framelocking is 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.
Note –
The only means of synchronizing multiple stereo displays using stereo
glasses and stereo emitters is through the stereo DIN7 connector (see “Connecting
the Stereo Port Framelock Cable” on page 48).
When frame buffers are framelocked, you should make sure they are all running at
the exact same vertical retrace rate. This is normally achieved by selecting the same
video format (resolution and refresh rate) (see
fbconfig -help
for details). See
“Configuring Graphics Accelerators for Framelocking” on page 50.
Note –
You will need either the DB9 framelock cable or the framelock stereo
synchronization cable to framelock Sun XVR-1200 graphics accelerators. Only one
type is required depending on your method of framelocking.
To order the DB9 port framelock cable, call Sun telesales at 1-800-786-0404 and
request spare part number 530-3188. You can also order the DB9 cable through the
Sun store (
http://store.sun.com
).
To order the stereo framelock daisy-chain cable, call Sun telesales at 1-800-786-0404
and request spare part number 530-2754. You can also order the framelock cable
through the Sun store (
http://store.sun.com
) by ordering this part number
under spare parts.
By default, video streams from separate Sun XVR-1200 graphics accelerators are not
framelocked.
