摘要： An accessibility device interfaces with a display through a cable to accept display onscreen menu items for presentation as speech from the accessibility device. For instance, a scalar of the display detects an interface with an external accessibility device and an end user interaction with an onscreen display and, in response, commands onscreen items as audible sounds presented at a speaker of the accessibility device. When the display has integrated display speakers, the scalar adjusts any audible sounds presented by the display speakers to help ensure that the onscreen display menu items are presented with sufficient volume to be heard, such as by lower the volume or turning off the audible sounds presented from the display speakers.

摘要： A system, method, and computer-readable medium for performing an intelligent display device detection operation. With the intelligent display device detection operation even if a user has not turned on a second information handling system, the display device automatically switch a video input from a first information handling system to the second information handling system when the second information handling system is coupled to the display device. When the user powers on the second information handling system, a video stream provided by the second information handling system is immediately presented on the display device. In certain embodiments, the intelligent display device detection operation comprises one or more of a signal detection operation which detects which input port is transmitting a signal and a cable detection operation which detects which input port is coupled to a cable.
