US 5,635,952 A · Adaptor enabling computer sensing of monitor resolution

Abstract

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.

Dependent claims

An adaptor for interconnecting a display monitor with a computer which provides image data to the monitor and said computer includes means for sensing resolution codes that identify the resolution at which the monitor is to operate, said adaptor being comprised of:

a first connector having means for engagement with said computer and having a first plurality of signal channels for receiving said image data from said computer, said first connector further having a plurality of sense lines for enabling detection of said resolution codes by said computer,
output means for transmitting said image data from said first plurality of signal channels to said monitor, said output means having a second plurality of signal channels which are connected to said first plurality of signal channels, and
manually operable rotary switch means for selectively establishing any selected one of a plurality of different electrical conditions at said sense lines, each of said conditions being a different resolution code that identifies a different monitor resolution.
