Hello ! Im looking at installing a 42 inch tv above fireplace. Room size: 14ft by 12 ft Viewing Distance: 10 Ft Fireplace height: 3Ft 11 inches Centre Speaker Height: 3 inches. THEREFORE.. the bottom of the plasma will be 4ft 2 inches from the floor. Whats everyones opinion.. Do I need a tilting wall bracket or is a fixed bracket ok. The plasma in question provides 160 degrees viewing angle. Many Thanks Guys... I just want to get it right first time. Thanks !
