All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative work fall within the protection scope of the present application.

The core of the present application is to provide a resolution and refresh rate switching method, device and medium.

In order to make those skilled in the art better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

At present, when manufacturers test some OS systems, graphics cards and display screens, they need to switch all resolutions and refresh rates for testing to confirm whether their display functions are normal. However, the resolution is related to the matching graphics card and display screen. Different configurations can support different resolutions, and each resolution is matched with multiple refresh rates. It will take a lot of time to manually switch all resolutions and refresh rates for testing. . Therefore, the present application provides a method for switching between resolutions and refresh rates, which is mainly applied to a scenario in which a large number of display devices are switched between resolutions and refresh rates. It should be noted that the switching scenario of the switching method of resolution and refresh rate in this embodiment is only a preferred embodiment, and does not limit the application scenario of the switching method of resolution and refresh rate, and other resolutions can also be applied. The scenario of switching between refresh rates and refresh rates depends on the specific implementation. FIG. 1 is a flowchart of a method for switching a resolution and a refresh rate according to an embodiment of the present application. As shown in Figure 1, the method includes:

Taking the Linux system as an example, you can use the "xrandr" command to obtain the name of the video interface supported under the current configuration and the connection status of the display device. The executable program for subsequent resolution and refresh rate switching can be implemented in python language. It should be noted that the implementation of the method for switching the resolution and the refresh rate in this embodiment through the python language based on the Linux system is only a preferred embodiment, and does not limit the implementation of the method for switching the resolution and the refresh rate. It depends on the specific implementation.

Further, after obtaining the name of the video interface and the connection state of the display device, the display information of the display device is generated according to the name of the video interface and the connection state of the display device. The display information includes the resolution and refresh rate supported by the display device connected to each video interface. It is understandable that for a display device, there may be different resolutions, such as 1920*1080, 1600*900 or 1280*960, etc.; and each resolution has multiple refresh rates, such as 1920* There are 60.00 and 74.97 refresh rates at 1080 resolution. The resolution and refresh rate of different display devices are determined by the display device itself, and the resolution and refresh rate included in the display device are not limited in this embodiment.

It should be noted that there is no restriction on the generation format of the display information of the display device in this embodiment; as a preferred embodiment, in order to realize the convenience of reading and writing and information identification, the format of the display information can be set to txt format. . After the display information is obtained, the resolution and the refresh rate under the resolution are switched according to the information, so as to display the image according to the switched resolution and the refresh rate. This embodiment does not limit the specific process of switching the resolution and the refresh rate under the resolution according to the information, which is determined according to the specific implementation situation.

As a preferred embodiment, switching the resolution and the refresh rate under the resolution according to the display information includes:

Traverse each line of information in the display information;

Divide each line of information into multiple strings;

In the strings of each line, the first string of each line is obtained as the resolution, and the remaining strings of each line are obtained as the refresh rate under the resolution;

Toggle resolution and then refresh rate under resolution.

In the above embodiment, there is no limitation on the specific process of switching the resolution and the refresh rate under the resolution according to the information, which is determined according to the specific implementation situation. As a preferred embodiment, after the display information is obtained, each row of information in the display information is first traversed.

FIG. 2 is a schematic diagram of displaying information according to an embodiment of the present application. As shown in Figure 2, in the display information, the resolution and refresh rate are presented in the information of the row. In order to extract the resolution and refresh rate, it is necessary to traverse each line of information in the display information, and divide each line of information into multiple character strings. It can be understood that, in this embodiment, a character division function is used to divide each line of information into a plurality of character strings. After obtaining multiple strings, in the strings of each line, the first string of each line is obtained as the resolution, and the remaining strings of each line are obtained as the refresh rate under the resolution. Toggle resolution and then refresh rate under resolution. For example, the resolution in a row is 1920*1080, and the refresh rate under this resolution is 60.00 and 74.97, then the switching resolution/refresh rate is: 1920*1080/60.00 and 1920*1080/74.97. After the resolution and refresh rate of the current line are switched, switch to the resolution and refresh rate of the next line.

In this embodiment, each line of information in the displayed information is traversed; each line of information is divided into multiple character strings; in each line of strings, the first character string of each line is obtained as the resolution, and the remaining character strings of each line are obtained as The refresh rate under the resolution is switched between the resolution and the refresh rate under the resolution in turn, and the switching of the resolution and the refresh rate under the resolution is realized.

If the connection keyword of the display device in the display information cannot be found, obtain the flag bit information;

If the flag bit information is 1, confirm that the information of the current line in the display information is the resolution and refresh rate, and enter the step of dividing each line of information into multiple character strings;

If the flag bit information is 0, confirm that the information in the current line in the display information is not the resolution and refresh rate, obtain the information in the next line in the display information, and return to the step of finding the connection keyword of the display device in the display information.

As shown in FIG. 2 , the resolution and refresh rate in FIG. 2 are the resolution and refresh rate of the display device connected to the VGA interface. It can be understood that the purpose of dividing each line of information into multiple strings is to obtain the resolution and refresh rate. However, as can be seen from the figure, the content of some lines in the display information is not the resolution and refresh rate, but the video interface and the refresh rate. Information about the display device it is connected to, or other useless information; and resolution and refresh rate may be included in the next line of information on the line containing information about the video interface and its connected display device.

In a specific implementation, before dividing each line of information into a plurality of character strings, the connection keyword of the display device in the display information is searched first. It can be understood that the display information includes the information of the display device connected to the video interface. However, in a specific implementation, due to some reasons, some display devices are not successfully connected, and the connection keyword is "disconnected"; and the connection keyword for a display device that is successfully connected is "connected". As shown in Figure 2, the keyword for the display device connected to the HDMI interface is "disconnected", indicating that the display device is not connected; and the keyword for the display device connected to the VGA interface is "connected", indicating that the display device is successfully connected, The resolution and refresh rate of the display device connected to the VGA port are in the next line of this line. It is important to note that in the row containing the resolution and refresh rate, the join keyword is not present.

Therefore, if the connection keyword of the display device in the display information cannot be found, the flag bit information is obtained; the flag bit information is used to determine whether the current row is the resolution and refresh rate information. If the flag bit information is 1, confirm that the information in the current line in the display information is the resolution and refresh rate, so that each line of information is divided into multiple strings, and the resolution and the refresh rate under the resolution are obtained. If the flag bit information is 0, confirm that the information in this line is not the resolution and refresh rate in the display information, and because the information in this line is definitely not the information of the display device connected to the video interface, confirm the information in this line. For useless information or error information, it is necessary to obtain the next line of information in the displayed information, and search for the connection keyword of this line again.

In this embodiment, the connection keyword of the display device in the display information is searched; if the connection keyword of the display device in the display information cannot be found, the flag bit information is obtained; if the flag bit information is 1, the display information is confirmed The information of the bank in the middle is the resolution and refresh rate. Enter the step of dividing the information of each line into multiple strings. If the flag bit information is 0, confirm that the information of the bank in the display information is not the resolution and refresh rate, and obtain The next line of information in the display information returns to the step of searching for the connection keyword of the display device in the display information, so as to determine whether the line of the display information includes the resolution and the refresh rate.

On the basis of the above-mentioned embodiment:

As a preferred embodiment, if the connection keyword of the display device in the display information is found, the method further includes:

Determine whether the video interface is connected to a display device according to the connection keyword;

If not, set the flag bit to 0, obtain the next line of information in the display information, and return to the step of finding the connection keyword of the display device in the display information;

If so, set the flag bit to 1, obtain the name of the video interface, and obtain the next line of information in the display information, and return to the step of finding the connection keyword of the display device in the display information.

It can be known from the above embodiment that among the rows of displayed information, the contents of some rows are resolution and refresh rate, and the contents of other rows are information or useless information of the video interface and its connected display device. Therefore, for a row of display information with a connection keyword, in order to facilitate the acquisition of the resolution and refresh rate of the next row of the row, it is necessary to set the flag bit information according to the display information of this row. Specifically, determine whether the video interface is connected to a display device according to the connection keyword; if it is determined that the video interface is not connected to the display device according to the connection keyword, that is, the connection keyword is "disconnected", and the flag bit is set to 0 at this time, confirming that the display device is not connected. , the resolution and refresh rate information is not included in the next line, further obtain the information of the next line of the display information, and find the connection keyword of the display device in the display information of the next line; The keyword is "connected", confirm that the display device is connected, the next line contains the resolution and refresh rate information, set the flag bit to 1, get the name of the video interface, and get the information in the next line of the display information, and find the information in the next line of display information. Displays the connection keyword of the device.

In this embodiment, it is determined whether the video interface is connected to the display device according to the connection keyword; if not, the flag bit is set to 0, and the next line of information in the display information is obtained, and the process returns to the search for the connection keyword of the display device in the display information. Step; if yes, set the flag bit to 1, obtain the name of the video interface, and obtain the next line of information in the display information, and return to the step of searching for the connection keyword of the display device in the display information. The setting of the flag bit is implemented to facilitate the judgment of whether the display information of the next line is the resolution and refresh rate.

On the basis of the above-mentioned embodiment:

As a preferred embodiment, after sequentially switching the resolution and the refresh rate under the resolution, the method further includes:

Print a screenshot file containing the data of the current resolution and current refresh rate after a preset time, and name the screenshot file with the current resolution and current refresh rate.

It can be understood that, in a large-scale display device resolution and refresh rate switching scenario, it is a very labor-intensive process for staff to continuously monitor the display status of the display device. Therefore, as a preferred embodiment, in this embodiment, a screenshot file containing the data of the current resolution and the current refresh rate is printed at a preset time after switching the resolution and the refresh rate under the resolution in turn, and the screenshot is taken. The file is named after the current resolution and current refresh rate to ensure sufficient time for resolution switching, so as to retain the display of the current resolution and refresh rate, so that the staff does not need to monitor in sequence in time, which can effectively reduce the energy consumption of the staff. It should be noted that the preset time is not limited in this embodiment, which may be 20 s or other time lengths, depending on the specific implementation.

In this embodiment, a screenshot file containing the data of the current resolution and the current refresh rate is printed after a preset time, and the screenshot file is named with the current resolution and the current refresh rate, so that the staff can easily check the resolution and the current refresh rate of the display device. The refresh rate is used for viewing, which improves the experience of the staff.

On the basis of the above-mentioned embodiment:

As a preferred embodiment, after dividing each line of information into multiple character strings, it also includes:

Remove the rest of the characters in the string except numbers.

It will be appreciated that, since the row containing the display information of the resolution and refresh rate, there may be other information in addition to the resolution and refresh rate. This information is useless for resolution and refresh rate acquisition, and may cause string reading errors. Therefore, in this embodiment, after dividing each line of information into a plurality of character strings, the remaining characters in the character string except the numbers are deleted, so as to obtain the processed character string, and prevent the character string from being read incorrectly from being erroneously distinguished. rate or refresh rate.

On the basis of the above-mentioned embodiment:

As a preferred embodiment, switching the resolution and the refresh rate under the resolution according to the display information includes:

Output the display resolution and refresh rate under the resolution through the xrandr command, and output the name of the video interface.

It can be understood that the xrandr command is the command for displaying the resolution and refresh rate under the Linux system. Therefore, switching the resolution and the refresh rate under the resolution according to the display information is specifically: output the display resolution and the refresh rate under the resolution through the xrandr command, and output the name of the video interface. The output result is "xrandr --output video interface name --mode resolution --rate refresh rate" to switch the display resolution and refresh rate.

In order to make those skilled in the art better understand the technical solutions of the present application, the above-mentioned present application will be further described in detail below with reference to FIG. 3 . FIG. 3 is a flowchart of the method for switching between resolution and refresh rate in an application scenario provided by an embodiment of the present application. As shown in Figure 3, the method includes:

S20: Use the "xrandr" command to obtain the supported video interface names and display device connection status under the current configuration.

S21: Generate a txt file, keep the video interface name and display device connection status.

S22: Traverse each line in the txt file.
