I'd guess my TV is tilted about 7 to 8 degrees which is about half of the available tilt. The angle I look up is about 6 degrees. My eyes are approximately 40" off the floor, the bottom of the screen is 52" off the floor and I sit about 10' away. Remembering my high school trig yields just short of 6 degrees. I was hoping to get the screen perpendicular to the line of sight. You may want to experiment with the angle to find one that avoids reflections but still provides good viewing.
