Resolution Setting Device for Adapter Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems often fail to display content correctly when using adapters, such as dongles, due to compatibility issues between the external monitor and the computer, leading to discontinuous or non-functional displays.
Innovation Solution
A method and device that involve a first processing device reading identification data from a display, obtaining and outputting second identification data to a second processing device, which then outputs a display signal based on the indicated resolution, using a resolution setting device with a processing circuit and storage circuit to ensure compatible display signals are sent, even in cases of adapter incompatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adapters (dongles) are used to connect different display interfaces, then compatibility between different interface types is improved, but display reliability deteriorates due to failure to display or discontinuous content
Solution Approach 1:
The patent applies preliminary action by having the first processing device read and obtain identification data from the display before the second processing device generates the display signal. This advance preparation of resolution information ensures that compatible display parameters are established before signal transmission, preventing display failures when using adapters between different interface types
Solution Approach 2:
The patent introduces an intermediary mechanism where the first processing device acts as a mediator between the display and the second processing device. It reads the display's identification data and provides this information to the second processing device, enabling proper signal configuration without requiring direct compatibility between the display interface and the source device, thus resolving the reliability issue while maintaining adapter versatility
2Device complexity
If identification data is read directly without intermediate processing, then device complexity is reduced, but measurement precision deteriorates due to inability to obtain accurate resolution information
Solution Approach 1:
The patent applies segmentation by dividing the identification data acquisition process into two distinct stages: first, the first processing device reads the raw identification data from the display; second, this data is processed and transferred to the second processing device which then uses it to generate the appropriate display signal. This segmentation allows each device to perform its specialized function while ensuring accurate resolution information is obtained and applied
