Wasn’t this a Frequenzy thing? When your Monitor works with 100 Hz your SAD light shouldn’t have 100 Hz, too?

Babylon 5 is so great. At the very end, unfortunately, I find it a bit confused. I missed what became of the host in the sealed vessel, for Sheridan’s child. Instead, at some point in an episode before, the evolution of humanity is seen (with the red eyes, downloading data from earth), before the Sun/Earth explodes. That should have been at the end.
