I have to mount a 15" Sharp LCD TV on a wallpapered wall. I will be using the cantalevered bracket by Omni-mount. The space where I need to put this TV is in between two studs, 20" apart. My questions is, will I be able to use toggle bolts to mount the LCD on the wall? I have mounted plasma TV's on the wall using toggle bolts but never with a cantalevered bracket. I don't want the toggles to break the drywall when the weight is extended on the bracket. Thanks for your input.
