hey avfan please help. remember my 50in tv is 55in off the floor and my new seating distance is 13ft from it but my tilt is set to 15 degrees max. my tv is recessed in the wall and it is extremely difficult to change the new max setting.

what happens if the tv is at 15 degrees as opposed to the ideal tilt? and at 15 degrees what would be the ideal viewing distance for i can move my viewing distance a few feet each way.

and given these measurements at 13ft what tilt would be ideal anyway? thanks for your help. angelo.
