In the house we are renovating due to the storm, we are pre-wiring for lcds or plasmas in both the master bedroom and the media room. Both of these rooms have 8' ceilings and we mounted the prewire boxes just under the 16" mark. So my question is: what is a good average height for these types of displays? The b/r will likely see a display in the 30" plus range and the media room in the 42-60" range...b/r viewing distance is apx 12' and the media room is apx 14-16' Also, we are pre-installing cross member studs between the up-rights for anchoring these displays to the wall. PLMK-Thanks!
