Adaptive GUI Scaling for External Display Devices

The patent separates the scaling process into two independent parts: video signal scaling and GUI scaling. The video signal is scaled according to the screen size ratio, while the GUI is scaled separately using a different ratio that accounts for both the screen size difference and the original GUI design characteristics. This segmentation allows each element to be optimized independently for its intended display conditions.

The patent applies different scaling ratios to different parts of the display output. The video signal receives one scaling ratio based on screen dimensions, while the GUI receives a different scaling ratio that preserves its usability. This local differentiation ensures that each component maintains its optimal display properties rather than being uniformly scaled.

The patent introduces dynamic adaptability to the GUI by calculating and applying different scaling ratios based on the detected screen size of the external display device. The GUI controller dynamically adjusts the scaling parameters according to the specific display device being used, allowing the same GUI design to adapt to various screen sizes without requiring multiple fixed configurations.

The patent changes the scaling parameter of the GUI based on the screen size characteristics of the external display device. By modifying the scaling ratio parameter dynamically, the system achieves adaptability to different screen sizes while maintaining the same underlying GUI design and configuration, thus balancing simplicity with versatility.
