I see that some connectors feature gold contacts. Does that make a difference in video quality?
A lot of people are surprised to hear that gold or nickel plating makes no difference at all when it comes to video quality. In truth, the use of gold plating in connector contacts is mostly driven by marketing and appearance. Keep in mind that most video signals travel through a combination of copper, lead, tin, silver, brass, aluminum, nickel or gold (or mixes thereof) before completing their journey.
