ABSTRACT:
A display for receiving video signals of a plurality of deflection frequencies including a conversion unit which is responsive to at least one of a horizontal frequency and a vertical frequency of an input video signal below at least one of at least one predetermined horizontal frequency within a first horizontal frequency range and at least one predetermined vertical frequency within a first vertical frequency range for converting the input video signal to have at least one of a converted horizontal frequency within the first horizontal frequency range and a converted vertical frequency within the first vertical frequency range. The conversion unit is further responsive to the at least one of the horizontal frequency and the vertical frequency of the input video signal being within at least one of the first horizontal frequency range and the first vertical frequency range for directly supplying the input video signal to the output of the conversion unit. The display is capable of displaying pictures represented by video signals from computers or image generating apparatus.
