How much does the picture quality increase with an RGB Scart cable?

[mojo]

What about the official Dreamcast scart cable?

I've heard that it's not full rgb scart and that it only has 9 pins as opposed to 21 you get with the 3rd party products.

Is this true?

Good,But Not Perfect

Reviewer: [email protected] from Swansea,Wales The Scart Lead Is A Great Improvement Over The R.F Cable But Miles Off The V.G.A Box.The Scart Lead Is In Fact A Composite Lead With A Scart Adapter On The End,Because There Are About 9 pins compared To A True Scarts 21.You Are Really Better off with a 3rd party lead as these are usually true scart at one and a half times the price.still a great product and it is offical,and as most people can't be bothered to connect their Dreamcast to a monitor or don't have a VGA compatible T.V The Scart Is definatly the best option if it's offical or not is up to you

No. You don't need to use all the pins to transmit full RGB. Nintendo's official GC RGB cable similarly only has the pins which are actually required.

So what are the extra 12 pins for?Don't they increase quality?

[Abhisara]

No. In the SCART standard, each pin carries a different signal. Some of these are not required in order to produce a full RGB picture. This is what each of the pins does:

Quite a few redundant for RGB-only. Audio/video input, for example.

The 9 pin scart apparantly lack the Red video ground, Green video ground and Blue video ground.

I wonder what difference these make?

Note: RGB Scart is a far superior picture to normal scart. Where possible, if your television supports an RGB picture, try and purchase a DVD Player that outputs its picture in RGB Scart. Picture sharpness and colour quality will be noticeably better as all 21 pins within the socket are wired. To achieve an RGB signal you also need to use an RGB scart cable that has all 21 pins wired up.
