My basement was finished when I bought the house and the area to put the big screen is built into the wall. The base of the TV sits 42-48" off the ground. My eyes are a few inches below the level of the base when I am on the couch. Doing that math, it works out to a 18-22 degree viewing angle. Does anyone have a DLP or Lcos set that is this high off the ground? If so, is the vertical viewing angle a problem? I currently have a 42" plasma but am looking to get a bigger set (up to 60"). I'm worried about the change in the picture of a DLP/Lcos if I am sitting that far below the center of the set.
