When is Composite Video not composite video (was: Best LCDs for retrocomputing)

Hi folks,

So, my 'new' monitor arrives today, beautifully packed and I wasted no time
in testing all ports; should've brought home the monitor tester I have at
work since it can generate Weird Frequencies, in fact I'll take the screen
in tomorrow and hook it up.

Anyhoo, all good apart from s-video which I can't test without something
that outputs s-video. I know the Commodore 64 does but I haven't made up a
cable for that yet, another thing on the TUIT list. Composite tested
courtesy of an original Playstation and Raspberry Pi.

Then I remembered that I've composite modded a Sinclair Spectrum and a ZX81
and I get no picture at all with those, like the signal is too weak for the
monitor to pick up. Said pair of machines work fine on my 2008-era LCD TV
though so does anyone know what the difference might be?

Just because I could I hooked the Spectrum up to an Apple ][ Monitor and
that works fine - http://binarydinosaurs.co.uk/IMG_8839.JPG

Are there variations to the PAL Composite standard?

In fact there was one available for ukp35 so it's now mine. I remember these
monitors from a few years ago at a customer that specialised in video for
aeroplanes, I used one not quite daily but remember being irked at the time
that it was several button presses needed to get from VGA to DVI input,
hahaha.
