The wall is 13 feet wide and 9.5 feet tall. where should i mount the LG42LH90 LCD-LED TV?
Sit on your sofa and look straight ahead. The TV should be mounted at eye level from your sitting position. That is the ideal position. Some folks hang them a little higher if you have small kids who like to keep their hands on things or want to run their toy cars over the screen, then mount it high enough so it’s out of reach.
