I'm not sure.  I have one monitor which is 1280x1024 with these numbers
in DECW$PRIVATE_SERVER_SETUP.COM and it looks OK.  With another machine
and another monitor, I had the same numbers, but the images were
stretched.  Obviously something wrong.  With the latter monitor and a
third machine (and different graphics card), I have again the same
numbers and the aspect ratio of a DECterm, say, looks OK.  Moving it
around, it looks like the real dimensions are 1024x768. 

There is the physical monitor (perhaps with the possibility to change 
some settings), the graphics card and various symbols and logical names 
defined when DECwindows starts up.  The connection between these three 
things is not clear to me.  In the monitor in which I am now typing 
this, the real dimensions appear to be 1024x768 but 1280x1024 are the 
values in the corresponding piece of DECW$PRIVATE_SERVER_SETUP.COM and 
it still "works".
