Genlock signal path

hi all!

OK, so I'm thinking of hooking several catalyst servers together to build a 270 degree surround video wall (7 screens, 4 servers)... I'll need to genlock them all together.


Am I correct in thinking that I need an NTSC video in card such as a Decklink that supports Genlock, or is there another method of getting blackburst into the server?

OR! If I'm going to be using resoultions/scan rates different than NTSC, is there another way of locking in frame accuracy across all the servers?


thanks!
