Automatic Sub-Display Positioning in Multi-Stream Transport Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-stream transport mode, information handling systems face challenges in automatically configuring sub-display positions, leading to random or incorrectly arranged sub-displays without user intervention, as the operating system lacks knowledge of edge-to-edge adjacency and positions of sub-displays.
Innovation Solution
An information handling system determines a display partition layout and transmits setup display patterns with encoded sub-display locations, using color patches or gray levels to reorder and correctly associate sub-displays with their designated partitions, enabling automatic configuration of sub-display positions without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the operating system automatically detects display partitions in multi-stream transport mode, then the configuration process is simplified and user intervention is reduced, but the sub-displays are arranged in random or incorrect positions due to lack of knowledge about edge-to-edge adjacency
Solution Approach 1:
The patent applies preliminary action by having the display device pre-encode position information and adjacency relationships into the display stream data before transmission. The operating system receives this pre-prepared information, allowing it to automatically configure sub-displays in correct positions without manual intervention. This resolves the contradiction by providing the automation capability while maintaining positioning accuracy through advance preparation of configuration data.
2Loss of information
If the operating system requests display information from the display device, then it can obtain configuration data, but the process requires additional communication overhead and time
Solution Approach 1:
The display device performs preliminary action by encoding all necessary configuration information including position data and adjacency relationships into the display stream in advance. When the operating system requests display information, the data is already prepared and embedded in the stream, eliminating the need for separate configuration queries and reducing communication overhead. This resolves the contradiction by minimizing information loss while reducing configuration time through advance preparation.

AI summary
In response to detecting that a display device is in a multi-stream transport mode, an information handling system determines a display partition layout of the display device. The system transmits setup display patterns according to the display partition layout of the display device, wherein the setup display patterns include a first display pattern and a second display pattern, wherein the first display pattern is associated with a first display partition, and wherein the second display pattern is associated with a second display partition. In response to determining that the first display pattern should be associated with the second display partition and that the second display pattern should be associated with the first display partition, the system associates the first display pattern with the second display partition and associates the second display pattern with the first display partition.
