Hello,
on LinuxTag 2011 in Berlin http://www.linuxtag.org/2011/ there was a
stand with 3x3 monitors powered by beagleboards. Nipuna and Koen should
know whos stand it was. I do not remember but Nipuna and Koen were
talking to the people there.
Best regards

we did a Videowall with 6 Beagleboards some time ago.

the hardware is here: http://www.flickr.com/photos/av500/sets/72157622794548090/
and the software running was omapfbplay: http://git.mansr.com/?p=omapfbplay;a=summary
omapfbplay has a netsync option to synchronize the master and the slaves
we used libav for decoding, but omapfbplay also has a libdce backend for OMAP4.
The libdce stuff would need to be adapted to the current libdce though and to
a different displaysink than v4l2...

Vladimir
