Big Panoramic Screen - 6 projectors

[SourceChild]

is, better to RUN 1 Catalyst with 2 TH2G, making the 6 screens @ 2400 x 600 each...
OR
Use 2 Catalysts SYNK, and 1 TH2G on each one

Short answer: Use 1 machine and have 1 backup system.

Another question, we wanna know if we have Captured with LFG Phoenix SDI cards, if we get almost no DELAY.....

My visual judgement is about 2-3 frames using LFG4 and 3-5 frames using 4 lane Phoenix. However, 4-6 frames on Extreme so you'll see the same issue.
