System and method for error messaging of an incorrect information handling system graphics cable connection
First Claim
1. A system for error messaging of an incorrect graphics cable connection, the system comprising:
- an information handling system having a graphics output port and operable to output a graphics signal at the port;
a peripheral having a graphics input port and operable to display a graphics signal communicated from an information handling system to the graphics input port, the peripheral further having a graphics output loop and graphics output port, the graphics output loop operable to communicate graphics signals received at the graphics input port for output at the graphics output port;
a graphics cable having first and second ends, the graphics cable operable to communicate the graphics signal from the information handling system; and
a cable connection detector associated with the peripheral graphics output port, the cable connection detector operable to detect a graphics signal input to the graphics output port and to display an error message with the peripheral.

Abstract
An incorrect connection of an information handling system graphics cable to a display peripheral is automatically detected with an error message presented by the display peripheral. For instance, a graphics projector accepts a VGA input from an information handling system through a VGA cable and port to project information for display. The graphics projector includes a graphics output loop that sends inputted VGA signals to an output port for communication to other peripherals, such as monitor. A cable connector detector associated with the VGA output port detects the incorrect coupling of a cable carrying an incoming graphics signal and displays an error message from the projector that the cable is connected to an incorrect port, such as a depiction of the input and output ports or a video showing disconnection of the cable from the outbound port and reconnection of the cable to the inbound port.

8. A method for error messaging of an incorrect information handling system graphics cable connection, the method comprising:
-
connecting a graphics cable to a display peripheral graphics output port;
communicating a graphics signal from an information handling system output port through the graphics cable to the display peripheral graphics output port;
detecting at the display peripheral the input of the graphics cable signal to the output port; and
displaying an error message with the display peripheral that explains that the graphics cable signal is input to an incorrect port. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
