So I have wall mounted a very large TV and my wall currently has a 1 foot x 1 foot hole that I used to install an outlet for power, there are like 8 holes in the wall, and then a 6" x 6" hole toward the bottom of the wall where my cables exit the wall.
I'm looking to sell my home within a couple of years and I would like the wall to look as new as possible. What method is done to do this and will my wall look like it has undergone a repair or is it possible to have a nearly invisible repair done?
I still have the original pieces of drywall, but I have no experience in repairing anything like this.
