This is a known problem. Old two-slot GX cards and the new Sony 19"
monitors don't get along together. The solution (excerpted from the
disconnect the 13W3 cable from the GX card; power off; wait 15
sec (aprox.); puwer on; wait till the 'idiot light' on the
front of the chassis starts blinking; plug the 13W3 back in
Stephen surmised that the old GX cards are hunting for a 66Hz monitor,
but he wasn't sure.
I ended up swapping in a single-slot GX card that was my hot spare.
Many thanks again go out to the group.
