Electronic Device Port Identification via HDMI EDID Query
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connecting electronic devices to content presentation companion devices, such as larger monitors or televisions, can be challenging due to the complexity of identifying the correct input port, especially when ports are closely packed and difficult to access, leading to confusion and incorrect connections.
Innovation Solution
The electronic device determines the connected port by querying the content presentation companion device using protocols like HDMI, which transmits an EDID extension identifying the port, allowing the user interface to display or announce the port identity, facilitating easy selection and ensuring proper connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If ports are closely packed to save space on the content presentation companion device, then the device footprint is reduced, but the difficulty of identifying and accessing the correct port increases
Solution Approach 1:
The system implements automatic feedback by querying the content presentation companion device to retrieve port identification information and displaying it on the electronic device's screen. This feedback loop eliminates the need for users to manually locate and identify ports physically, resolving the contradiction between compact port packing and ease of port identification.
2Adaptability or versatility
If multiple ports are provided on the content presentation companion device to support various connection types, then device versatility is improved, but the complexity of identifying the correct port increases
Solution Approach 1:
The system employs self-service automation where the electronic device automatically queries the content presentation companion device for port information and displays the correct port identification. This eliminates the need for users to manually determine which port to use, reducing identification complexity while maintaining support for multiple connection types.
3Device complexity
If manual port identification methods are used, then device complexity is minimized, but user error and connection failures increase
Solution Approach 1:
The system introduces automatic feedback through port querying and display, where the electronic device retrieves and shows the correct port identification from the content presentation companion device. This automated feedback mechanism significantly reduces user error and connection failures while maintaining reasonable system complexity.

AI summary
An electronic device includes a communication device and a user interface. The communication device detects establishment of an electrical communication channel to a content presentation companion device. One or more processors operable with the communication device and the user interface cause the communication device to query the content presentation companion device for a content presentation companion device port facilitating the electrical communication channel and, in response, cause the user interface to identify the content presentation companion device port.
