Multi-monitor Display System Using Video Data Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for using multiple monitors require separate video graphics drivers, hardware upgrades, and consume significant power, making them expensive and inefficient, especially with USB ports lacking sufficient bandwidth for high resolution.
Innovation Solution
A multi-monitor system utilizing a video receiver and splitters to split video data according to the DisplayPort standard, allowing multiple displays to share video data, eliminating the need for separate drivers and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate video graphics drivers are used for each monitor, then each monitor can be driven independently, but the system becomes expensive and complex
Solution Approach 1:
The patent implements a universal video driver that can drive multiple monitors simultaneously through a single interface. The driver is designed to handle multiple display outputs without requiring separate driver instances, allowing one driver to perform the function of multiple drivers while maintaining full control over all connected monitors.
Solution Approach 2:
The patent combines multiple monitor control functions into a single integrated driver architecture. Instead of maintaining separate driver processes for each monitor, the system merges all monitor control operations into one unified driver that manages multiple display outputs through shared resources and common control pathways.
2Adaptability or versatility
If hardware upgrades are performed to add each extra monitor, then multi-monitor support is achieved, but the cost increases significantly
Solution Approach 1:
The patent creates a universal video driver that enables existing hardware to support multiple monitors without requiring additional graphics cards or hardware upgrades. The single driver can manage multiple display outputs through the existing video interface, eliminating the need for expensive hardware additions.
Solution Approach 2:
The patent allows a single driver instance to be copied or replicated across multiple monitor contexts without requiring separate physical driver copies for each display. The driver creates virtual instances or contexts that share the underlying hardware resources, enabling multiple monitors to be driven through software rather than hardware multiplication.
3Ease of operation
If USB ports are used to drive additional monitors, then connectivity is simplified, but bandwidth is insufficient for high resolution displays
Solution Approach 1:
The patent introduces an intermediary video interface that sits between the USB connection and the monitor displays. This intermediary layer processes and manages the video data stream, optimizing the use of available USB bandwidth through efficient data packing, compression, or prioritization schemes that enable high-resolution display output despite USB bandwidth limitations.
Data Source
AI summary
A multi-monitor display is disclosed. A multi-monitor display receives video data configured for a single N×M video display; splits the video data into a plurality of portions spanning the N×M display; and transmits the plurality of portions to a corresponding plurality of displays. The multi-monitor display system can be any system, for example a display-port system or an ePaper system.
