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.

An image producing apparatus includes a photoconductor. A photonic energy device is positioned adjacent the photoconductor. A reflecting member is located adjacent the photonic energy device, whereby at least a portion of the reflecting member is operable to deform upon application of an electrical voltage in order to direct photonic energy from the photonic energy device towards the photoconductor with the reflecting member. The reflecting member may direct the photonic energy from the photonic energy device towards the surface of the photoconductor in order to discharge portions of the surface of the photoconductor to produce an image.

Projector bulb life is managed to achieve desired performance parameters, such as a maximum life mode or maximum brightness mode, by sensing bulb luminance and applied the sensed luminance with a luminance feedback controller to drive the bulb to achieve the desired performance parameter. For instance, in maximum life mode the luminance feedback controller reduces power applied to the bulb to restrict bulb luminance to a maximum luminance setpoint when greater luminance is available with a newer bulb. In maximum brightness mode, the luminance feedback controller increases power applied to the bulb to increase bulb luminance if the sensor senses luminance below a threshold due bulb wear. Bulb life management improves project image illumination to display information in a variety of projector types, including digital mirror devices and liquid crystal displays.
