Embodiment Construction

[0038] The invention is applied to the data processing equipment to adjust the working frequency of the graphics card of the data processing equipment. The data processing device refers to an electronic device capable of data processing, including but not limited to a desktop computer, a notebook computer, and the like.

[0039] When the data processing device is in operation, the present invention can use simple operations to complete the adjustment of the working frequency of the graphics card according to the user's needs, so that the data processing device can be easily adapted to different working modes and use environments, which is convenient for the user to use as much as possible. Potentially prolonging the operating time of the data processing device in battery usage mode.

[0040] Please refer to FIG. 2 , which is a flow chart of the method for switching the operating frequency of the graphics card in the present invention.

[0041] Step S110, storing the frequency...

Abstract

The disclosed method comprises: storing the SDI frequency state for user selection; detecting current supported frequency; receiving user input information for selection; comparing the operating frequency of user's selection and the supported; if failed, outputting current frequency for selection again; or else, regulating the opposite attribution of display memory; finally, returning regulated information.

Description

technical field [0001] The invention relates to data processing and display technology, in particular to a method and device for switching the operating frequency of a graphics card. Background technique [0002] At present, notebook computers are becoming more and more popular, and the graphics cards selected are also varied. Graphics cards with different specifications have different default operating frequencies. For example, the maximum operating frequency of NVIDIA’s graphics card model NV41M-U is 450MHz, the maximum operating frequency of NV43M graphics card is 375MHz, and the maximum operating frequency of NV44M-V graphics card The highest operating frequency is 300MHz. Since high frequency can improve performance and achieve a higher display level, more and more high-frequency graphics cards are used in notebook computers. [0003] However, when we just use a notebook computer to play ordinary DVD movies, or when we just use a notebook computer to write documents, ...
