Is this the technical way of saying "Plug that thing into a green
phosphor monitor, plug your //e into the CRT TV, and end it there"?
If so, I suppose that makes sense, but the last time that I plugged a
IIgs into an LCD TV (and a big LCD at that--it was a demonstration for
a user group), it looked outstanding! I'd describe it as being top-
quality composite. Not RGB, of course, but a real gorgeous big
composite image. And now I'm plugging a IIgs into a 13" CRT and I get
a totally different result.
Really just time to give up on putting the IIgs on a color composite
screen?
