 Diagonal screen sizes
Screen sizes are sometimes specifi ed by their diagonal size (D) in inches. When 
dealing with large screens and projection distances at different aspect ratios, it is 
more convenient to measure screen width (W) and height (H).
The example calculations below show how to convert diagonal sizes in inches into 
width and height, at various aspect ratios.
