Recently we had a computer that was setup for
PAL ( B&W ).
We tried it on one of those Sony monitors that has a
select for everything. We never were able to get it
to work. Latter we tried an old black and white monitor
( well black and green ). We were able to adjust the
vertical and horizontal enough to get it to work.
I guess it really depends on what you expect. I think
the Sony may have been looking for the color burst
or maybe the audio to lock onto. The computer we had
only produced video B&W out.
Well, the B&W signal is (with an exeption of the
VerticalF/Lines ratio) the same for both - and since
the resulting horizontal frequency is (almost) the
same, most B&W monitors are able to display NTSC and
PAL (or better US and European B&W) with only minor
adjustment. A good buy here is an Apple /// screen.
Simple, ad still fairly available.
