I recenty bought my first home and want to mount my 46" plasma over my fireplace. I bought a Monoprice.com tilting wall mount and tonight when I was doing a little prep, I found out that the studs over the fireplace are not placed 16" apart. I have one stud in the dead center of the wall but to the left and right of that, they are 22" apart. Anyone have any suggestions on how to mount this thing?
