Curved Single Monitor FOV Calculator
1. The results are calculated as a range. Try starting with the higher number.

2. The higher number is calcuated using the flat screen projection.
    Consider the top view of your monitor, it's an arc of a circle, then draw a line that connects either end of that arc.
    The distance used to calculate the FOV is the distance to this line, and NOT to the actual screen.

3. The lower number is calcuated as if the screen itself is flat.
Input Actual width of the monitor including the bezels,
the calculation will compensate for them.
Actual height of the monitor including the bezels,
the calculation will compensate for them.
