Not sure about silver content but length/gauge should be considered. Use bigger gauge for longer runs to avoid dropouts. The 22ga would be better than the 24ga in case of long run. Short runs I would get the 'thinner' stuff for greater flexibility. I do suppose the silver would help in signal transmission but curious as to how well with long runs. I use a older/regular monoprice hdmi to my pj...30 ft thru wall, attic, and in to the pj...no problems as I have used it for more than 5 yrs.
