Mounting a TV can take as little as one to three hours. However, the time it takes to mount a TV depends on the size and location of the TV, the complexity of the setup and additional factors. In general, more complex systems will require more time. A typical installation will include installing a TV mount on the wall, floor or ceiling, mounting the TV to it, routing cables so they’re not visible  and testing to make sure the system works.
