Hey gang. Long time audiophile but new to the forum. I will be installing a wall mount TV and I usually use keystone jacks for my computer and audio cable runs, but I haven't used them for video before. I only see female to female HDMI couplers for keystone jack installs (
https://www.primecables.ca/p-310550-cab-6852-hdmi-female-to-female-coupler-adapter-keystone-jack-white-primecables ). Any issues using 3 cables and 2 couplers for 4K over HDMI? (Wall plates behind the receiver and the TV.) Can you get HDMI punch down connectors and bulk cable or does HDMI cable need to be terminated at the factory? I've seen plenty of videos where they use wall plates with holes in them and feed pre-made cables through the holes, which only requires a single cable, but the wall backs onto a bed room so I prefer not to have any holes that could allow sound transmission into the abutting room.
While on the topic of wall plates, I also like to run the audio optical out from the TV to the receiver and see SC Keystone jacks for this purpose (
https://www.primecables.ca/p-317466-cab-2876-modular-sc-keystone-jack-white-monoprice ). Do these couple optical cables that are already terminated in an optical connector? FWIW, this will be a relatively short run with the TV mounted above the audio console.
