So you've just bought a shiny new big screen HDTV and it's barely an inch deep. But all that slimness is put to waste if it's sticking several inches off the wall because of your mounting hardware. If you're really trying to get as flush as possible, then here's a great option for a literal 0" wall mount. How's that you say? Read on!If you're fortunate enough (or plan ahead enough) to have your TV smack dab in the middle of two 16" on-center wall studs between three 16" on-center studs (simply cut out part of the middle non-load bearing stud) you can go with a recessed wall mount, like this $100 model. These mounts invade into your walls, requiring you to cut out your drywall. With all of the metal hardware squeezed between and securely mounted to two studs, the TV can essentially sit perfectly flush with the wall. Since most walls are made out of 2x4s, you'll get 3.5" of depth for the mount, giving you plenty of room for adjustment when you need it. You can pull out over 2 feet from the wall, tilting -5/+15 degrees up and down and swiveling 60 degrees left or right.
As you can see with my own installation, there's plenty of access space for power and cables. Per our electrician, since the mount pulls out, for accessibility reasons it's allowed to have the plug tucked back behind the TV for a completely clean look.
For those DIYers looking to save a few bucks (not that $100 isn't totally reasonable), you could also achieve the same look by mounting a blocking board in a wall cutout and using a cheaper standard mount. Either way, it's a clean, flush look that's fairly easy and inexpensive to accomplish.
