Maybe with an analog signal where less interference or a higher quality cable mattered (think old coax cabling), but you are dealing with a digital signal (right?). It will either get there or it won't. Gold plating will not make difference.
I mean with any signal, whether it is for keyboard and mouse to monitor signal. Can you get gold plated ethernet cables? With any cable, is it improved performance if it's gold plated?
