Dynamic EDID Adjustment for Seamless Multi-Display Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display methods require manual settings to adjust display ranges and cannot automatically change extended display identification data (EDID), affecting image quality and user experience in multi-device display systems.
Innovation Solution
A method and system where the main display device changes its EDID based on the connection order of display devices, allowing for image segmentation across multiple devices to ensure consistent resolution and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual setting is used to change display range of each display device, then display devices can perform display according to relative connection positions, but user operation complexity increases and automation is reduced
Solution Approach 1:
The display device automatically detects connection relationships with other display devices and autonomously configures its display range and EDID information without requiring manual user input. The device serves itself by determining its position in the splicing system and adjusting parameters accordingly.
Solution Approach 2:
The display device receives feedback about connection relationships from other devices in the system and automatically adjusts its display configuration based on this information. The system continuously monitors connection status and dynamically modifies display parameters to maintain optimal splicing display performance.
2Manufacturing precision
If display device cannot spontaneously change EDID, then system configuration is simplified, but image quality resolution of display image deteriorates
Solution Approach 1:
The EDID information of the display device is made dynamic rather than static. The device automatically changes its EDID parameters based on the detected connection relationship and position in the splicing system, enabling the system to optimize image quality resolution for different display configurations without requiring complex manual setup.
3Manufacturing precision
If automatic EDID change is implemented, then image quality resolution is improved, but device complexity increases
Solution Approach 1:
The display device autonomously manages its own EDID information based on connection detection, eliminating the need for external configuration tools or complex user intervention. The automatic EDID change mechanism is integrated into the device's normal operation, allowing it to maintain optimal image quality while keeping the user interface simple.
