LFD Based Videowalls

Has anyone already specified Videowalls based on LFD technology? How does it work? Any specs?

Is it a good option for surveillance purposes. Which are the Pros and Cons?

Best regards.

Hello Carlos:

Could you define 'LFD technology'? It looks like "LFD" or "Large Format Display" is primarily a Samsung marketing term for panels supporting a video wall management application. Does that sound correct?
