Problems solved by technology

[0008] There are some deficiencies in the switching method of this prior art: firstly, the process is complicated, there are many steps, the work efficiency needs to be improved, and users who are not familiar with the system will feel that the operation is very cumbersome, which affects the user experience
Secondly, VGA Driver provides multiple resolutions for users to choose. In many cases, users do not know what resolution they need to switch to. For example, widescreen LCD supports 800*600, 1024*768, 1280*768, etc. If the user chooses a wrong resolution, it is likely that the display cannot be displayed or the best display effect cannot be achieved.

example

[0077] An example of the present invention is an adjustment scheme currently used by Lenovo's Tianyi notebook computer. This notebook computer is a 15:9 WXGA LCD widescreen display mode. The default display resolution is 1280*768, which can have a good performance in image. The shortcut key program can quickly switch between 1280*768 and 1024*768 resolutions.

[0078] The switching method in this example adopts the combination key code switching function (or mode switching button) issued by a special key on the keyboard. The switching in this embodiment is switching from "15:9 WXGA LCD widescreen display mode" to "4:3 XGA LCD normal display mode".

[0079] Due to the use of the present invention, the advanced operations required by the user are greatly reduced, from the original 7 steps to only 2 steps; In the case of display, complete all switching actions (during the switching process, problems such as black screen may occur due to different display modes, and problems su...

Abstract

The invention discloses a method for switching the resolutions of a display system, used for a display system comprising a data processing unit and a display unit, including the steps of: storing display resolutions for a user to select; receiving a resolution selecting message of the user; detecting the display modes supported by the display system; comparing the user-selected resolution with the supported display modes and judging if the display system can support the user-selected display mode: if no, prompting the user to select a resolution again and otherwise, regulating the display effect in the selected resolution; switching the current resolution into the selected resolution. The invention also discloses a device for switching the resolutions of a display system.

Description

technical field [0001] The invention relates to data processing and display technology, in particular to a method and device for switching the resolution of a display system. Background technique [0002] At present, notebook computers are becoming more and more popular, and the LCD (liquid crystal display) selected is also varied. The resolutions used by LCDs of different specifications are usually different. For example, the resolution of traditional XGA LCD is 1024*768, the resolution of SXGA LCD is 1400*1050, the resolution of UXGA LCD is 1600*1200, and the resolution of widescreen LCD is 1280*800 or 1280* The 768 comes in two different resolutions, corresponding to 16:10 or 15:9 display modes. [0003] With the development of information technology, more and more high-resolution LCDs and wide-screen display LCDs are used in notebook computers. High-resolution LCD has great advantages in displaying details, and wide-screen LCD has great advantages in its image, but som...
