Display Controller Dynamic Resolution Adjustment for Video Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current displays lack the ability to dynamically adjust video streaming configurations and resolutions based on connection states, leading to suboptimal video quality, especially when switching between video ports, as they cannot appropriately communicate with the source device to adjust settings such as frame quality.
Innovation Solution
A display system with two ports and corresponding display controllers that detect connection states and provide original or adjusted resolution data to the source device, allowing for dynamic adjustment of video streaming configurations to ensure optimal video quality, either using a single port for original resolution or both ports for adjusted resolution, which is half of the original, to display complete frames effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If double video line configuration is used to increase transmission bandwidth, then the transmission bandwidth is increased, but the device complexity increases
Solution Approach 1:
The display device is designed with dual video ports that can operate in multiple modes: single-port mode for standard resolutions and dual-port mode for high resolutions. This multi-functionality allows the same hardware infrastructure to serve different bandwidth requirements without adding permanent complexity, resolving the contradiction between increased transmission bandwidth and device complexity.
Solution Approach 2:
The system dynamically adjusts its operational configuration based on detection results. The controller can switch between single-port and dual-port operation, and dynamically adjust resolution settings based on connection state. This dynamic adaptability allows the system to optimize bandwidth utilization without permanently increasing device complexity.
2Manufacturing precision
If the display uses fixed original resolution data, then the video quality is maintained, but the adaptability to different connection states deteriorates
Solution Approach 1:
The display device dynamically adjusts resolution data based on detected connection states. When one port is connected, original resolution data is used; when both ports are connected, adjusted resolution data is applied. This dynamic adaptation maintains video quality while improving adaptability to different connection scenarios.
Solution Approach 2:
The system changes the resolution parameter based on connection state detection. By switching between original resolution data and adjusted resolution data, the system optimizes video quality for each specific connection scenario, resolving the contradiction between maintaining video quality and adapting to different states.
3Adaptability or versatility
If the display automatically detects connection state and adjusts resolution, then the adaptability improves, but the control complexity increases
Solution Approach 1:
The display device performs automatic connection state detection and resolution adjustment without requiring manual configuration. The system serves itself by detecting port connection states and autonomously selecting appropriate resolution data, improving adaptability while minimizing the need for complex external control mechanisms.
Solution Approach 2:
The system implements a feedback loop where the controller detects connection states through the ports and uses this information to adjust resolution settings. This automated feedback mechanism improves adaptability while keeping control complexity manageable through systematic detection and response protocols.
4Quantity of substance
If adjusted resolution data with half resolution is used in dual-port mode, then the bandwidth utilization is optimized, but the manufacturing precision deteriorates
Solution Approach 1:
In dual-port mode, the video signal is segmented into two separate streams, with each port handling a portion of the total display content. The adjusted resolution data divides the original resolution by two, allocating appropriate bandwidth to each port while maintaining overall image quality through coordinated display of both segments.
Solution Approach 2:
The system changes the resolution parameter to half of the original when operating in dual-port mode, optimizing bandwidth utilization. By coordinating the display of both adjusted-resolution streams, the system maintains acceptable video quality while efficiently utilizing the available transmission bandwidth.

AI summary
A display and a method for displaying video frames thereof are provided. In the method, a connection state between a first port, a second port and a source device is detected. When only one port is connected to the source device, an original resolution data is provided to the source device through the port and a video streaming transmitted from the source device is received. The video streaming is divided and respectively outputted to the display by a first display controller and a second display controller. When the first port and the second port are both connected to the source device, two adjusted resolution data are provided to the source device through the first port and the second port respectively, and two video streamings transmitted from the source device are received and outputted to the display by the first display controller and the second display controller respectively.
