Multi-Display Control Apparatus with Trigger Event Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-display settings, especially in mirror display mode, content from a laptop PC can unintentionally be displayed on an external device immediately after connection, requiring users to press specific keys to switch off the multi-display mode, which is not user-friendly and can result in unintended content being shown.
Innovation Solution
A multi-display control apparatus and method that includes a processor and memory to detect a trigger event, such as connection of an external display, and temporarily stops the display on the external device, allowing users to select a display mode through a display mode selection screen before content is shown on both screens, thereby preventing unintentional display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mirror display mode is selected for multi-display connection, then the external display device can show the same content as the laptop PC, but the content is displayed on the external device immediately after connection which may be unintended
Solution Approach 1:
The system performs preliminary action by displaying a confirmation dialog before actually outputting content to the external display device. When an external display is detected, the system shows a dialog asking the user to confirm whether to enable multi-display mode, preventing unintended content display before it occurs.
Solution Approach 2:
The confirmation dialog acts as an intermediary between the external display connection and the content display. This intermediate step allows the user to review and confirm the display mode selection, preventing direct and potentially unintended content output to the external device.
2Ease of operation
If the operator wants to switch off multi-display mode quickly, then the operation should be simple, but the current method requires pressing special key combinations that are not user-friendly
Solution Approach 1:
The system provides self-service by automatically detecting external display connections and presenting display mode options to the user. This eliminates the need for users to manually access complex key combinations or settings menus, as the system proactively manages the display mode selection process.
3Speed
If the system displays content on external device immediately upon connection, then the response time is fast, but the content may not be what the operator intends to display
Solution Approach 1:
The system implements feedback by displaying a confirmation dialog that shows the user the intended display mode before executing it. This feedback mechanism allows the user to verify and correct the system's intended action, ensuring that the content displayed on the external device matches the user's intent while maintaining quick response time.
Data Source
AI summary
A multi-display control apparatus includes a processor for an information handling device and a memory that stores code executable by the processor. The code is executable by the processor to detect a trigger event and, in response to detecting the trigger event, temporarily stopping display of content on a first display device in which the first display device is external to a second display device of a computing device storing the content.
