There are many resons to mount your TV, including safety as a major concern. There is also a growing trend towards smaller homes that have an open floor plan with a multi-purpose "great room". By mounting the TV in these rooms you can achieve greater visability in a smaller footprint.
With all the adances in TV technology and the growing number of mounting solutions is there is no reason to have a poor floor plan! (see previous post: necessary evils). Gone are the days of lining all the furniture along one wall so "everyone can see." Flat screens alone allow for a wide viewing angle, and with the addition of Sanus products your mounting options are endless.
Let's take a look at some of their solutions that might work for your home.
You can't beat the flexibility of this wall mount. You can literally mount a TV in the corner, you can pivot, angle, and pull out from the wall. This ensures everyone can have the perfect view, and you can adjust to reduce glare as needed.
I like this sketch above because it clearly shows the corner mount which is awesome. One thing I don't like about it though is the fireplace is right next to the TV, which creates a focal point competition. In this case mounting above the fireplace would be a better design decision to reinforce one focal point. Or move the TV to another wall away from the fireplace.
Another beneift of a wall mount is the flexible furniture options, if you choose to have any at all! In this case they chose to drop the cords behind the wall and add artwork for a gallery wall effect.
Sometimes all you need for a perfect view is a little tilt. Some examples would be a wall mount in the bedroom, over a fireplace, or to angle for little kids to see.
