Amiga 1200 PAL <--> NTSC

[Hyperspeed]

American TVs don't have a 23-pin Scart socket like European TVs right?

Scart/Euro Peritel cables are a Godsend and include composite, S-VHS
and RGB video signals all in the same little plug.

PAL/SECAM/NTSC are only methods of transmission of UHF I believe, so
they only apply to RF/Composite signals.

Those are of a poor quality anyway, so why not try opting for RGB?
Surely US TVs accept RGB since most games consoles have an RGB cable
for them.

RGB will give you crisp video straight from the chips with no
deterioration. Arcade machines, consoles and computers use RGB display
devices so why should your Amiga settle for fuzzy RF or inferior
composite display?

Try holding down both mouse buttons when switching the Amiga on until
an Early Boot Menu appears. By pressing a key you can toggle between
your Amiga's video capability.

It says PAL/NTSC but on my PAL A1200 it switches between PAL 50Hz/PAL
60Hz.

The PC never had such video compatibility trouble, but then the PC was
markedly less versatile as a result.

Not many people know why there are so many variants of PAL.

SECAM is another variant.

According to some documentary on satellite TV, the reason they differ
from each other is due to political isolation.

Before the Berlin wall came down the Soviets wanted to keep western
transmissions away from the people so you'll find East German
computers of the 80's had a different variant of PAL. I think it was a
modified version of the French SECAM system.

It's all about stopping cross border proliferation. A bit like DVD
Region 0, 1, 2 etc. but with broadcasts.

You avoid all this nonsense by getting an RGB cable as it hooks
directly to the chips and bypasses modulation.

I'm not sure why composite uses PAL/NTSC since UHF/VHF is different to
a direct signal like composite.

Maybe someone in broadcasting can shed some light on this.

The latest version of RGB now appears to be HDTV, I wonder if there is
AmigaOne support for this... it'd be interesting to know how good the
AmigaOS4 Screenmode prefs utility is!

What is that little dip switch on an Amiga RF output? There's a little
screw potentiometer next to it as well.

Is this for variations of PAL for countries like Argentina?

Is it as simple as turning the screw a few twists and getting PAL-B
etc. and SECAM with a click of the dip switch?
