Intelligent Display Device Detection for Automatic Video Input Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when frequently connecting and disconnecting information handling systems to display devices, as they need to manually switch the video input source, which disrupts the user experience.
Innovation Solution
An intelligent display device detection system automatically switches the video input from one information handling system to another when connected, and back to the original system when the second is disconnected, using signal and cable detection operations, with options to enable or disable this feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual switching of video input source is used, then the display device can show video from different information handling systems, but the user experience deteriorates due to frequent manual intervention required when connecting and disconnecting systems
Solution Approach 1:
The display device automatically detects when a second information handling system is connected and autonomously switches the video input source without requiring user intervention. The system monitors connection status and performs switching operations itself, eliminating the need for manual source selection by the user.
Solution Approach 2:
The system continuously monitors the connection status of information handling systems to the display device and uses this feedback information to automatically trigger source switching operations. When a disconnect event is detected, the system receives feedback about the changed connection state and responds by switching back to the previous source.
2Ease of operation
If automatic detection and switching is implemented, then user experience improves by reducing manual intervention, but the device complexity increases due to additional detection operations required
Solution Approach 1:
The patent replaces manual mechanical switching operations with automated electronic detection and control mechanisms. Instead of requiring physical user interaction with source selection buttons or menus, the system uses electronic cable detection operations and signal presence detection to automatically control the video input switching, substituting electronic automation for manual mechanical operation.

AI summary
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.
