These diagonals are another fine example of commercial obfuscation. A computer monitor billed as being so many inches (in the U.S.) is actually about an inch (sometimes two) smaller, because the American law allows the measurement to include the casing. In Canada, the law stipulates the measurement must be of the viewable area, but the economic power of our southern neighbour is such that the law is systematically flouted.
