Super High Res

[ChaosLord]

So it seams then the Amiga is packing the signal vs doubling it to get a higher resolution.  I can see how most monitors are unlikely to support this.

1280 pixel mode is a bog standard video mode.

Any monitor that doesn't support it is either
A: A ripoff piece of crap
B: Very very very old
C: Broken

I'm bloody confused with all that.  So I have an AGA Amiga (1200) and the mode 'works' just looks blurry.

Ok.  What kind of monitor are you using?  LCD or CRT?

So I think I userstand the ide behind keeping it 200-256 lines to keep compatibility with broadcast, but I don't understand 1280 if it's not 1280.

It is 1280 pixels.  There is nothing fake about it.

It's not  a 30Hz mode so I don't quick get what's doubled if it's not really 1280 pixels across?

It is absolutely 1280 pixels across.

What's faster about 16 colours?  I thought it was restricted to 4?

On AGA:
1280 mode is not restricted to 4 colors.
1280 mode is not restricted to 16 colors.
1280 mode is not restricted to 256 colors.
1280 mode can use the full 16 million color palette in HAM8 mode, which is the main purpose of 1280 mode: viewing photographs in 16 million colors.

1280 mode is not restricted to 200/256 pixels height.  It can also do 400/512 pixels high.  When I use 1280 mode I use 1280x512.

well, it works but its barely usable.

It is the most usable mode there is for viewing photographs.

Have you ever heard of a thing called "porn"?

In reality, 1280x200/256 is hardly ever used.

That is because 1280x512 is so much better.
