If you have a TV that doesn't have any mounting holes, there are a few ways that you can still mount it. One option is to use a TV stand that has a base that you can screw into the wall. Another option is to use a TV mount that has arms that extend out from the wall. You can also use a combination of both methods.
If you're using a TV stand, the first thing you need to do is find a stud in the wall. Once you've found a stud, you'll need to use a drill to make a hole in the wall that's big enough for the base of the stand to fit into. Once the hole is drilled, you can screw the base of the stand into the wall.
