Perhaps a set with component inputs would do things better.  Frankly,
I expected that when I fed the video into the Luminance input of the
S-video connector, the resolution would be stunning--but it wasn't.
At present, I have to assume that many monitors combine processing
for S-video and composite very soon after they enter the set, and
don't have high expectations for either one.  ;-(

This may be a simple artifact of the LCD monitor I was testing, since
it also thinks it is a TV receiver.


Both my 32" Sony WEGA CRT and my Samsung 17" LCD did a good job
with composite, 40-column text, etc.--not to be confused with a high
resolution image, just a big image.  Games would be fine.


I take this to mean that 80-columns were not usable?

While 80-column text was readable, it was not very clear.  For example,
lower case 'm' and 'w' were not resolved, but could be distinguished in
context.

I wouldn't want to do program development with this kind of display.

I've been frustrated by my lack of a wideband composite-input monitor
for 80 column work; I have a few cheap TVs, all of which are
unreadable. I could possibly justify a purchase of one of those Dell
DVI/VGA/composite LCD displays, but no one seems to spec the composite
interface bandwidth, and most of the video-to-digital converter chips I
was able to google for had built-in lowpass filters below the 14 MHz or
so that the old Apple monochrome monitors had.

The only one that I *know* works fine is the AppleColor Composite
monitor.  It has special (unique?) circuits that switch the video
bandwidth to wideband when there is no color burst present or when
the "monochrome" button on the front panel is pressed.
