A1200 Composite versus Video
On the back of my 1200 there's a small round composite video output, there's also a video port. I've just seen on ebay a lead that runs from the Amiga's video port and 2 audio sockets, to a scart lead. Would this video socket output (to scart) offer any improvement in clarity over a regular composite to scart?
Btw, I'm like this on any forum. I type stuff out, it makes sense to me, but in all actuality - reads like utter nonsense, typed by a headcase. |

Most TV's DO support RGB input on one of the SCART sockets. However there is an RGB sense pin (sometimes called FastBlank) which needs to be driven for the TV to recognise the RGB signals.

Most TVs of the last 5-10 years have a RGB-capable Port, but usually just 1 of them.
Some descriptions on the net are however incomplete, you need apart from 2xAudio and 3xVideo a few other connections - one is sync, one is a "RGB-Switch" which needs to be some odd Voltage like 2V and I think there was another one I forgot. PS. I think the Amiga-Port has a Pin called composite, I kinda expected the Cable I built to run with non-RGB Scart too, but it doesnt? Oh and RGB Picture Quality is kinda like 3 times better Edit: Theres the Scart Pinout Pin 8 should go to 12V Pin 16 should go to 1-3V (connect through a Resistor around 700 - 800Ohm to 12V ) Last edited by Npl; 16 December 2004 at 00:30. |

Amiga's cannot produce composite video without a modulator. A500's had the A520, 1200's and 600's have an internal chip that goes to the comp-sync Phono jack. There is unfortunately no way to make a 100% functional RGB & Composite video cable with just wires. Last edited by alexh; 16 December 2004 at 21:47. |

Then you get the same bad picture as if you connect the compisite connector directly to the TV.
The advantage of the Scart thing is that the TV uses the RGB lines without any quality loss. Using the composite line in the Scart plug does not make any sense unless your TV does not have a composite-in connection. |

I only have 1 RGB Port on my TV, which is not enough for a PS2 and an Amiga. Why should I keep seperate Cables for RGB and nonRGB if a single one could work? |

This thread has gotten a little too technical for me, but does that webpage above look right to anyone? |
