Do you have a recommendation on how I should mount my display for the best viewing angle?
This will ultimately be subjective to whoever is installing/using the device, and there is no wrong or right answer here. Here's some sound advice we've found based off of some expert opinions on the matter:
"Your eye level is calculated, not standing, but sitting where you’ll be watching the TV.
Measure the distance from the floor to your eyes to find out how high you’ll be sitting. In regards to viewing angle, per the Society of Motion Picture and Television Engineers, you’ll want the TV to be mounted for a viewing angle of not more than 30 degrees. Most people, however, casually sit between 10 to 15 degrees reclined.
As a rule, a 42” television should be mounted about 56 inches from floor to TV center, a 55” TV should be around 61 inches, a 65” TV should be around 65 inches’ floor to center, and a 70” television should be mounted about 67 inches to the center of the screen."
