Have you tried another monitor?

My work machine is a SPARCstation LX.  When it was connected to a CRT,
all was well.  Now it's on a flatscreen, and there are flickering
horizontal streaks when there is host activity.  (I'm not sure whether
it's disk activity, CPU, Ethernet, or what.)  I haven't cared enough to
track down exactly what is provoking it.
