TV Mount Types

I carry both fixed and full motion brackets. Full motion brackets have the benefit of changing the TV angle and easy access to plug in cords, but they need to hit at least one stud in the wall (one stud is fine if it hits the middle of the bracket--otherwise it needs to hit two studs. Studs are commonly 16 inches apart but often in DC they're 24 inches apart and requires a TV bracket that spans 24 inches).

This is the best full motion bracket in my opinion--https://www.amazon.com/gp/product/B09TT243J1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. It can accommodate 24 inch stud spacing.

Running Wires Through Walls & Cable Channel Covers

I have the tools needed to run wires through the walls. The wall needs to be drywall to do this--it's not worth the headache of attempting to do it on plaster walls. 

A frequent issue with running wires in the walls is not having HDMI cables that are long enough to make the full run--I carry 10 foot HDMI cords and 12 foot power extension cords that can be expensed as well (see pricing below).

I also carry cable channel covers for situations where running wires in the walls isn't possible or preferred (i.e. in rental apartments). The kits I use are white, can be easily painted, and can be mounted to the wall via small screws or double sided tape.
