A TV wall is intended to host the TV on that particular wall. There will be communications plate for 1 coaxial, and 5 RJ45 jacks. There will also be 4 electrical gangs, and as with all electrical outlets, there will be 2 USB-C ports. The gangs will have 2 outlets. This will be a total of 8 outlets, and 8 USB-C jacks. Your TV will plug the coaxial cable from the TV to the jack for the TV services. There will be 5 RJ-45 jacks for networking items. An example might be a NAS? that might function as a media server. The NAS will plug into the RJ45 on the wall, and into an electrical outlet. You might do the same for an ATA?, game systems, and smart TV adapters. You do not have to use all of the jacks, and gangs, but they are there if you should need it.
