What are they?  Anything from an Indigo onwards can drive VGA or SVGA. 
I have an Indy and an O2 with LCD panels, and used to have a VGA monitor 
on an Indigo (so I expect my LCDs would work).  An Indy even has an 
S-video o/p already (nitpick: SVHS is a tape format) though I've never 
tried using it without IRIX running.  I've never used older SGIs than 
that but I thought if you got the right levels on the monitor sense pins 
on the ones with 13W3 connectors, they'd output at sensible rates with 
appropriate sync signals.  Doesn't help if you only have 3 x BNC, of 
course; you'd at least have to construct a sync separator, but that's 
potentially just a one-chip stripboard design.
