I am putting in a new TV and I am running all new wires through the wall including electrical and cable, can these two wires run next to each other, or will that cause any kind of interference??
Unless you're installing this TV in a motor vehicle, you're in the wrong category. Why not look for a better place to ask your questions.
It depends. There are various kinds of Cat 5 cables. There is the Unshielded Twisted Pair (UTP) and the Shielded Twisted Pair (STP) Cat 5 cables. If youre running parallel to electrical wires, you may want to consider the STP cables as UTP as susceptible to electromagnetic interference.
