Okay, the LCD arrived a few days ago & have to say it's absolutely awesome. However, before I buy the necessary leads, it has as array of connections which includes two scart sockets one of which is RGB enabled. I have bought a RGBS scart apaptor to plug into the back of the LCD but do I actually need a RGBS lead to conect from sky or will a normal RGB lead suffice?? Is there any difference in quality?? These are £50 so want to enusre I buy the right one & not waste any money.
