Because some 13w3 monitors are Sun or IBM compatible in addition to pure
SoG.  Those monitors expect sync signals on some of the small pins.
SGIs use the small pins to query monitor ID information (to set a sane
default resolution).  Some monitors (like my IBM P200) interpret this as
sync data and try to sync to too high a rate, and just give up.

If you don't want to butcher the cable, get a 13w3<->BNC cable and
another monitor<->BNC cable.  Use thinnet T-taps to join the red, green,
and blue pairs.
