Display EDID Switching for Rapid Gaming and Multimedia Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are limited to a single display size when purchasing, requiring multiple displays for different needs, and current adjustment features are cumbersome and difficult to switch quickly between scenarios.
Innovation Solution
A display with a memory, physical switching element, and controller that allows users to switch resolution and screen size with a single button, utilizing candidate extended display identification data stored in the memory and controlled by the controller based on switching signals from the physical element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users purchase multiple displays of different sizes to meet various usage needs, then the adaptability to different scenarios is improved, but the device complexity and cost increase
Solution Approach 1:
The display device is designed to perform multiple functions by supporting different display modes (gaming mode with high refresh rate and multimedia mode with high resolution) through a single device. The controller switches between different EDID data sets to enable the display to adapt to different usage scenarios, eliminating the need for multiple specialized displays
Solution Approach 2:
The display changes its operational parameters dynamically by switching between different EDID (Extended Display Identification Data) configurations. The controller selects appropriate EDID data based on the desired mode, changing parameters such as resolution, refresh rate, and screen size to optimize performance for either gaming or multimedia applications
2Adaptability or versatility
If users adjust display size through software menu, then the adaptability is improved, but the switching speed between scenarios deteriorates
Solution Approach 1:
Multiple EDID data sets are pre-configured and stored in the display's memory before use. Each EDID data set corresponds to a specific display mode (gaming or multimedia) with all necessary parameters pre-defined. When mode switching is required, the controller simply retrieves the pre-configured EDID data, enabling instant switching without requiring users to manually adjust multiple parameters through software menus
3Measurement precision
If display resolution is increased for multimedia, then the image quality is improved, but the refresh rate decreases affecting gaming performance
Solution Approach 1:
The display dynamically adjusts its operational characteristics based on the selected mode. In multimedia mode, the display operates at high resolution with standard refresh rate to optimize image quality. In gaming mode, the display switches to lower resolution with high refresh rate to optimize frame rate and responsiveness. This dynamic adaptation allows the single display to optimize for either image quality or speed depending on the application

AI summary
A display (1,2,4) includes: a memory (11,21,41), a physical switching element (13,23,33,43) and a controller (12,22,32,42). The memory (11,21,41) is configured to store multiple pieces of candidate extended display identification data (EDID-1,EDID-2). The physical switching element (13,23,33,43) is configured to be triggered by external force to generate a first switching signal. The controller (12,22,32,42) is connected to the physical switching element (13,23,33,43) and the memory (11,21,41). The controller (12,22,32,42) is configured to control a displayed screen according to original setting data among the pieces of candidate extended display identification data (EDID-1,EDID-2), and adjust the displayed screen according to target data that is different from the original setting data among the pieces of candidate extended display identification data (EDID-1,EDID-2) after receiving the first switching signal.
