    I tend to usually buy cables that have gold plating and 99.99% oxygen free copper, and triple shielding. But what are these for? Can they make an improvement in picture?

    First, either a picture is OK or it isn't - you get sparkles if it isn't.
    I assume this is about HDMI cables by the way.
    The gold plating is on the connectors to make sure they can be plugged and unplugged a number of times without oxide on the surface.
    The OFC is on the wire itself, this is cheaper than using gold plated wire and makes in very difficult for the wire to oxidise, this would increase signal loss on longer lengths and thus cause dropout (sparkles).
    The triple shielding is simply to make sure there isn't interference between the wires within a cable or between cables. Double shielding should be fine but triple seems to be the standard these days.
