An adaptor for coupling a display monitor to a computer that controls the monitor generates any selected one of a number of codes that can be sensed by the computer and which identify the image resolution at which the particular monitor operates or a resolution that has been selected by the operator in the case of multi-sync monitors. A rotary hexadecimal switch, which may be operated by turning a dial, simplifies code selection and a multi-channel dip switch enables expansion of the number of available codes. The dip switch also enables selective changing of sync signal connections within the adaptor to accommodate to different monitors that have different sync signal input requirements. The adaptor may be a separable unit which can be interconnected between the computer and monitor or may be a permanent built in component of the monitor image data input cable.
