We have five TVs in the house :
For the living room, home theater and basement TVs, I have pulled two Cat6e cables each. One is for network and the other for our HDMI over IP modules.
Two of the TVs are "smart". I have connected them to my switch on a private VLAN dedicated to the TVs.
The first four TVs are also connected to a single MacBook in the library. The HDMI transmitter module is plugged into a PoE switch that then feeds video and power to the receiver modules. It allows us to watch the news and TV shows on all of those four TVs.
My 42" TV is HDMI-only. It has no network outlet. Instead, there is an HDMI cable in the wall with two outlets, connecting the TV to my iMac on the other side of the wall.

It is actually my mom's old MacBook Air.
