There isn't a "right" FOV, finding the right balance it's all about the ratio between the distance from the screen and the screen size. More details here: http://www.youtube.com/watch?v=blZUao2jTGA http://www.youtube.com/watch?v=S1XsPYPGcl0

What do you mean?

At high FOVs there is visual distortion of the image that doesn't just magically go away as you increase your distance to the screen.
