Daisy Chained Display Remote Control via Logical Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In daisy chained display configurations, users face difficulties in remotely controlling display settings due to unclear display topology and the need to reach rear-mounted controls, leading to a cumbersome user experience.
Innovation Solution
An automated address assignment scheme is implemented, where each display in the chain generates a unique logical index based on incremental address information, allowing remote control of display settings through a logical index system that simplifies user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If displays are daisy chained through a single display port, then cable management is simplified and display density is increased, but remote control of display settings becomes difficult due to unclear display topology
Solution Approach 1:
The patent introduces an intermediary addressing system that mediates between the user and the daisy-chained displays. Each display is assigned a unique address that it communicates to the host system, allowing the host to identify and control specific displays in the chain without needing to physically trace cables or access rear controls. This intermediary addressing layer resolves the contradiction by enabling remote control while maintaining the simplified daisy-chain topology.
2Shape
If manual display controls are moved to the rear of the display perimeter to minimize bezel thickness, then aesthetic appearance and bezel uniformity are improved, but user accessibility to controls deteriorates
Solution Approach 1:
The patent replaces the mechanical/physical control system with an electronic/software-based control system. Instead of requiring physical access to manual buttons on the display rear, the system uses software interfaces and remote control mechanisms that communicate with displays through their assigned addresses. This substitution eliminates the need for users to physically reach behind displays while maintaining uniform bezel design.
3Device complexity
If multiple displays are interface through a single display port with daisy chain configuration, then device connectivity is simplified, but display identification and setting control becomes ambiguous
Solution Approach 1:
The patent implements preliminary address assignment for each display in the daisy-chain configuration. Before control operations begin, each display is pre-configured with a unique address that identifies its position in the chain. This preliminary action ensures that when control commands are issued remotely, the host system can accurately identify which display should receive which settings, eliminating ambiguity without complicating the physical connectivity structure.

AI summary
Daisy chained displays that present information from an information handling system as visual images has remote support of display settings provided through an address assignment scheme to communicate display settings to specific displays of the daisy chain and allows each display to determine a numerical index of the display for presentation at the display. A remote control session for display settings accepts inputs based upon the numerical index presented at each display and sends the display setting inputs through the daisy chain to the address associated with the numerical index for application at the display.
