Are there any devices for telling what HDMI or copper cables go together when running them through a wall? (lemmy.ca)

I know I can use an HDMI source like a Raspberry Pi and a small screen for HDMI and could twist copper cable together and measure continuity through them to narrow down which is which but I'm wondering if there is an easier way. Maybe something I connect to either end?

Very true if you are doing a lot of work like that. I was only suggesting the easiest method for what I assume would be a one time thing.
