TOPIC



    The Multiple Scan 15 manual has measurements for the display that don't correspond to this display. Is the manual wrong?

DISCUSSION


    This question arises across our entire monitor line. While it may be a bit confusing, the explanation is rather simple.

    Since the advent of television in the 1940s, Cathode-ray tubes (CRTs) have been identified by their physical diagonal dimension. For example, a 19-in. television set has a CRT that measures 19-in. diagonally. However, part of the CRT is behind the plastic bezel so it measures something less than 19-in. diagonally when measured from the front of the television set. This method has been adopted not only by the television industry but also by the computer/monitor industry. All monitor vendors use this method and Apple is no different. If the bezel was removed and the Multiple Scan 15 Display CRT was measured diagonally it would indeed measure 15-inches. There is no deception intended--it's just the way it's be done for over fifty years.
