Have a good day, even if what I describe isn't the problem :^)
The older DEC 3000 Model 600 probably has an "HX+" graphics card, which only
supports a limited number of resolutions and scan rates -- 1280 x 1024 at
60Hz and 72Hz, most likely.
The newer AlphaStation 400 4/233 probably has a "TGA" graphics card, which
is also called a ZLXp. This graphics card can be set for any of a number of
graphics resolutions. Your new 21" monitor probably autoadjusts to match
the graphics card. I wouldn't be surprised if your graphics card is set for
1024 x 768 resolution instead of 1280 x 1024.
You probably got documentation for the graphics card with the system; it so
it has a table with diagrams that explain how to set the dip switches on the
graphics card for different resolutions. If you don't have documentation I
can probably explain it in words, but the pictures and tables are best.
If you set the graphics card for 1280 x 1024 and power cycle the system (the
switches are only read at power up), your monitor will probably start to
work in 1280 x 1024 just fine.
I've done this on systems with the "TGA" card and the 16" VRC16 monitor; the
graphics cards seem to come set for 1024 x 768 as the default.
