VGA Cable

[Zahary Karadjov]

Hello,
I'll be building VGA to RGB Scart cable as proposed in this article:

I'm wondering which particular cable should I buy for the task.
Can someone evaluate for me the importance of shielding of each of the
cores involved in the cable: RGB(3), RGB Grounds, Sync, Sync Return.
Thank you for your help and sorry if my english or terminology is not
very good.

Individually screened signal wires are essential.
Gold plated contacts and low oxygen copper cables a waste of money IMHO

Just use an old cable from a scrapped SVGA monitor, if they're good enough
for the monitor they're good enough for a SCART TV. I'll even *give* you one
for the cost of postage, but I suspect you could find one locally for a lot
less.

To avoid ghosting issues, use 75 ohm cable for each of the RGB pairs.
As stated elsewhere in this thread, you can cannibalise an old monitor
cable for this purpose.

The article states that VGA pin 13 is composite sync. My understanding
is that pin 13 is horizontal sync and pin 14 is vertical sync.
Furthermore, sync polarity varies according to the graphics mode. Can
Powerstrip redefine the function of these pins for TV mode?
