: The sharpness of a monochrome monitor is limited only by its
: focus (normally quite good) and the bandwidth of the video
: source and amplifier.  (OK, another thing that can--rarely--
: blur the display is a dirty, scratched, or diffuse faceplate.)
:
: It is quite common for monochrome monitors to have 15MHz to
: 20MHz bandwidth, comparable to the bandwidth of the Apple II
: video output.  This makes almost any monochrome monitor _very_
: sharp compared to any dot-matrix color display, regardless of
: mode.
:
: BTW, the limiting bandwidth may not be achieved if the display
: is overdriven (contrast too high).  The proper way to adjust a
: monochrome display is to turn the brightness control up until
: just below the point where the black parts of the raster begin
to
: be visible, then turn the contrast up to the lowest setting
that
: produces acceptable "brightness" in the white areas.  This
: ensures that the video amplifier is not overdriven.

I've always adjusted mine that way by logic, but never knew just
why I was doing it. Some people like that slightly brighter part
of the screen background showing, the rectangular shape, but I do

not. I prefer to only see the actual text/graphic portion.  :o)
