Multiple display device system and method for automatically setting display-mode

Abstract

A multi display system includes a CPU, central display, external multi-displays linked to CPU and display detector. The detector is for real time detecting each outer display and sending detected data to CPU. The CPU is for real time recording of the display pattern and contents of each external display. At receiving signals from detector, CPU makes corresponding display control. In case of disconnecting signal, CPU stops recording and stores present content and modifies display pattern and sends the content to the central display. In case of connecting signal, CPU resumes recording pattern and automatically set the display content according to corresponding records.

Description

technical field [0001] The invention relates to the display technology of a multi-display system, in particular to a multi-display system and a method for automatically setting a display mode thereof. Background technique [0002] With the continuous development of computer and information technology, information display becomes more and more important. Throughout the history of computer development, it will be found that in terms of human-machine interface, computer monitors have become larger and larger, from the initial 14 inches to the current 17 inches and even 20 inches; the resolution has also changed from the original CGA, EGA's current high resolution of 1024×768 is even higher; the color has also changed from monochrome to 16-color, 256-color, and then to the current 24-bit color; all of which mean that more information can be displayed on the display. [0003] However, due to the limitation of display technology, it will be more expensive to manufacture large-sca...

AI Technical Summary

Problems solved by technology

[0024] First, the cost is high. Not only the display device must provide its own parameter storage device, but the display adapter must also provide a circuit for reading parameters and a mechanism for reporting to the system;

[0025] Second, there are too many intermediate links in the system control, which is not direct, and the system is prone to unreliable problems;

[0026] Third, it is impossible to take into account various types of graphics output interfaces, such as interfaces other than the VESA standard;

[0027] Fourth, it is difficult to automatically switch displays in real time;

[0028] Fifth, it cannot automatically restore to the original working state

[0029] To sum up, in the multi-monitor system of the prior art, there are relatively large obstacles when multiple monitors are plugged, switched, and moved, which makes it more inconvenient for the operator to use, and the work efficiency is not high and the user experience is poor. poor
