example 1

[0075] The application hardware system and operating system environment of the preferred example 1 are as follows.

[0076] The graphics card of the notebook computer has two output interfaces, one is directly connected to the LCD display on the notebook computer, which is a 13.3-inch wide-screen LCD panel with a resolution of WXGA 1280×800 and an aspect ratio of 16:10; One output interface is RGB analog output to an external display, usually the external display is much larger, such as a 21-inch LCD display with a resolution of 1600×1200 and an aspect ratio of 4:3.

[0077] Because the size, aspect ratio, and resolution of the two displays are different, there must be an adaptive transformation of the display mode and a transformation of the position calculation. Simultaneously, because the difference of the two displays is very different, so the combined display effect is not good, so it is not recommended in this example, but it does not hinder the implementation of the pre...

example 2

[0086] In this example, a host has four digital display adapters, and each adapter is connected to a digital interface display. The performance of these four display adapters is exactly the same, and the parameters such as functions and performance of the four 15-inch 1024×768 displays are also the same. . The purpose is to splice into a larger display.

[0087] Other aspects are similar to the aforementioned preferred example 1, and here we focus on how to implement coordinate switching and display mode transformation for combined display of multiple displays.

[0088] Such as Figure 13 As shown in , where display A is the main display, and in the extended display mode, choose to combine the windows on display A to four displays in display A, and the steps are as follows:

[0089] Adjust the display modes on all four monitors to the same mode; change the coordinates of the four corners of the window on monitor A from A1, A2, A3, A4 to A1, B2, C3, D4; enlarge all images twi...

Abstract

The invention relates to a windows switching method for multi-display screen system. It includes the following steps: displaying window in display screen; the control attribute of window at least containing sending window attribute and uniting display window attribute, and it could be moved under maximum state; receiving the operation instruction from user; taking sorting resolution to the instruction; determining window location according to the result; changing the location and finishing window switch. The invention also supplies a multi-display screen system.

Description

technical field [0001] The invention relates to data processing technology related to graphical user interface, in particular to a multi-display system including a host computer and multiple displays and a method for switching windows between multiple display screens. Background technique [0002] With the continuous development of computers and information technology, information display is extremely important, and it is increasingly required to display more information on the display. [0003] Throughout the history of computer development, it can be found that as a human-machine interface for computers, the size of the display is getting larger and larger, from the initial 14 inches to the current 17 inches, or even 20 inches, and it is more useful to have a super large projection of more than 150 inches. The screen is used for demonstration and explanation; the resolution has also changed from the original CGA and EGA to the current high resolution, such as 1024×768 or e...
