What's the point of your comment? The Decstation
5000/200 doesn't
have these connectors so it doesn't make any difference. The
standard cable provided by DEC for these machines basically took
their 3 pin connector to 3 BNC connectors. This can be connected
to a monitor that has BNC connectors and supports the appropriate
frequencies. Since the video connectors on the 5000 series
workstations were somewhat unusual they can easily be overlooked
by someone who isn't familiar with them.
My point is that it's rather silly to talk about "standard" video
connectors,
especially in a forum like this. The same could be said of a 13W3 or a D15HD.

I don't recall that particular resolution. Each of
the graphics
adaptors (there was about a dozen of them) had its own resolution
and there was no easy way of changing it. The graphics displays
were not near as flexible as the SGIs of the same time period.
I've got a table of resolutions for the DEC graphics adapters here...
HX graphics options:
OPTIONS RESOLUTION JUMPER CLOCK
PMAGB-BA/BB 1280X1024 72Hz off 130. mhz
1280X1024 66Hz on 119. mhz
PMAGB-BC/BD 1280X1024 72Hz off 130. mhz
1024x864 60Hz on 74. mhz
PMAGB-BE/BF 1280X1024 72Hz off 130. mhz
1024x768 72Hz on 130. mhz
Don't ask me how to tell one from the other... =)

But a graphical client/server model that slices the interface down some
arbitrary middle is like Solomon following through with his child-sharing
strategy. The legs, heart, and left eye end up on the server, the arms and
lungs go to the client, the head is left rolling around on the floor, and
blood spurts everywhere.
