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.

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.
