The market for analog monitors is quickly developing into

1) LCD TVs that expect HD or SD video; I believe most of the composite
inputs for these will filter out what they expect to be composite
audio+video from a legacy DVD or VCR player; i.e. unusable for 80
column video.

2) LCD monitors that accept VGA-style video inputs (treating them as
analog RGB with the VGA sync), either on a DB-15 or DVI connector, but
typically no composite input.



An HD LCD with component input should display usable 80-column text and
monochrome graphics if you run a cable from the video output to the Y input
and leave Cb and Cr disconnected.  It won't be color, but that wasn't an
issue with most of the software I used back in the day.


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.


(Maybe I should try testing this theory sometime.  My TV is a 30" widescreen
LCD with a native resolution of 1280x768.  The only input currently in use
is DVI from the MythTV box, so one of the component inputs should work.)


I'd be interested in what you find.


If you want color, you could just switch to a composite input.  Any display
with component input should also have composite input.


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.

This, perhaps, is the fundamental problem with all the inexpensive
scan doublers--they were designed for games, not text displays--so
horizontal "pixel crawl" isn't much of an issue.
