[0025] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and so that the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0026] Figure 1 A schematic diagram of an application scenario 100 based on resolution adjustment scaling according to an embodiment of the present disclosure is shown. The application scenario 100 shows an application scenario when a display screen connected to a computing device is changed from one to multiple, and / or an application scenario when an existing display screen is replaced by a new display screen. Referring to Figure 1 In the application scenario of adding display screens, the computing device is initially connected to only display screen 0, and then N display screens, i.e., display screen 1 to display screen N, are connected, i.e., the computing device is changed from being connected to one screen to being connected to multiple screens. It should be noted that N can be a number determined as needed. For example, when N is 2, it means that the display screens connected to the computer device are increased by display screen 1 and display screen 2, and at this time the computing device is changed from being connected to one screen to being connected to three screens. In the application scenario of replacing display screens, display screen 0 is replaced by display screen M due to business needs.

[0027] In these two scenarios, since the configuration or number of display screens is changed, the resolution configured by the computing device for each display screen is correspondingly adjusted. The present disclosure is based on the problem that scaling does not automatically adjust when the resolution is adjusted, and adjusts the scaling according to the adjusted resolution, so that the desktop is presented with the best display effect and the user has a good experience.

[0028] For other application scenarios in which the resolution is adjusted, for example, the display screens are restored from multiple to one, or the resolution of the display screens is changed by manual modification by the user, although not shown in Figure 1 , but also within the scope of the application scenario of the present disclosure.

[0029] Figure 2 A schematic block diagram of a computing device 200 according to an embodiment of the present disclosure is provided. As shown in Figure 2 , the computing device 200 includes a processor 201 and a memory 202, and the processor 201 and the memory 202 are connected by a bus 203, such as an I2C (Inter-integrated Circuit) bus.

[0030] Specifically, processor 201 provides computing and control capabilities to support the operation of the entire computing device. Processor 201 can be a Central Processing Unit (CPU), but it can also be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor.

[0031] Specifically, the memory 202 can be a Flash chip, a read-only memory (ROM) disk, an optical disk, a USB flash drive, or a portable hard drive, etc.

[0032] Those skilled in the art will understand that Figure 2 The structure shown is merely a block diagram of a portion of the structure related to the embodiments of the present invention, and does not constitute a limitation on the computing device on which the embodiments of the present invention are applied. A specific server may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0033] The processor is used to run a computer program stored in the memory, and implements any of the resolution-based scaling methods provided in the embodiments of the present invention when executing the computer program.

[0034] Figure 3 A flowchart of a resolution-based scaling adjustment method 300 according to an embodiment of the present invention is shown. Method 300 is executed in a computing device (e.g., the aforementioned computing device 200) for adjusting scaling according to resolution to enable a desktop application to display optimally. Method 300 includes the steps of: determining the maximum supported scaling based on the adjusted current resolution in response to completion of current resolution adjustment; and performing scaling adjustment based on a comparison between the maximum scaling and the actual scaling.

[0035] like Figure 3 As shown, method 300 begins with step S310 and includes steps S310 and S320:

[0036] The S310, in response to the completion of the current resolution adjustment, determines the maximum scaling that the display can support at the current resolution; and

[0037] S320 adjusts the scaling according to the comparison result of the maximum scaling and the actual scaling.

[0038] Before the method of the present application is further elaborated, the basic technical terms in the present application are introduced first. The resolution in the present application includes the physical resolution and the compressed resolution of the display screen. The physical resolution and the supported resolution are two important parameters of the display screen. The physical resolution is also called the best resolution, the standard resolution, the original resolution, the true resolution or the actual resolution. It is a mathematical expression of the actual existing pixel row number multiplied by the column number of the display screen. It is an inherent parameter of the display screen and cannot be adjusted. Its meaning is the highest number of pixels that can be displayed by the display screen. The supported resolution is other resolutions supported by the display screen. No matter which resolution, it is usually expressed in the form of "horizontal pixel number x vertical pixel number", such as 800x600, 1024x768, 1280x1024, etc.

[0039] For example, as shown in the table, the physical resolution and the supported resolution provided by a display screen are shown. Among them, "3840x2160 (recommended)" is the physical resolution of the display screen, and other resolutions such as "2560x1600", "2560x1440" and other supported resolutions are other resolutions supported by the display screen. Figure 4

[0040] Copy mode: The copy mode is to make the multiple display screens connected by the device display the same content.

[0041] Extended mode: Two display screens are virtually combined into one large screen display to achieve a wider desktop space.

[0042] First, in step S310, in response to the completion of the current resolution adjustment, the maximum scaling that can be supported by the display screen under the current resolution is determined.

[0043] When the computing device is plugged in or the display screen is replaced, or the number of connected display screens changes, the resolution will be adjusted accordingly. After the resolution adjustment is completed, since the scaling cannot be adjusted adaptively, sometimes the desktop and application windows cannot be fully displayed.

[0044] Among them, the scenarios in which the display screen is adjusted include changes in the number of display screens and / or changes in the configuration of the display screen. Further, the number of display screens changes include an increase or decrease in the number of display screens; the configuration of the display screen changes include the display screen being replaced and / or the configuration of the display screen being modified and changed.

[0045] ​In some embodiments provided by the present application, when the accessed display screen changes from one to multiple, the display mode and the current resolution of the multiple display screens are determined according to preset rules. Specifically, when there is a same resolution supported by the multiple display screens, the multiple display screens are loaded in a copy mode, and the maximum value in the same resolution is determined as the current resolution of the multiple display screens; and when there is no same resolution supported by the multiple display screens, the multiple display screens are loaded in an extension mode, and the current resolution of each display screen is the best resolution of each display screen.

[0046] It should be noted that the copy mode mentioned in the present application refers to that the multiple display screens connected to the graphics card display the same content. The extension mode refers to that the multiple display screens are virtually combined into one large display screen to display the content together, so as to realize a wider desktop space.

[0047] For example, initially, the graphics card of the computing device is connected to only one display screen. When one display screen is added, so that the graphics card of the device supports two display screens at the same time, the physical resolution and the supported resolution of the two display screens are first acquired, and the resolutions of the two display screens are compared one by one. If the supported resolutions or the physical resolutions of the two display screens can find the same value, i.e., the resolutions with the same horizontal pixels and vertical pixels, the current resolutions of the two display screens are set to the maximum resolution in the same value, and at this time, the two display screens are loaded in the copy mode since they have the same resolution.

[0048] For example, if the supported resolutions or the physical resolutions of the two display screens cannot find the same value after the comparison, the current resolutions of the two display screens are set to the respective best resolutions. Further, since the current resolutions of the two display screens are not the same, the two display screens are loaded in the extension mode to obtain a better display effect of the desktop application.

[0049] In another embodiment provided by the present application, when the accessed display screen changes from one to multiple, the display can also be performed according to the preconfigured resolution and display mode.

[0050] For example, the preconfiguration can be set as follows: after the multiple screens are accessed, the extension mode is recommended to be loaded, and the resolution of each display screen is the best resolution of the display screen itself. Of course, the default parameters in the preconfiguration can also be adopted, and the present application does not limit this.

[0051] In some other embodiments provided by the present application, when the display screen changes from the multiple screen mode to the single screen mode, the current resolution of the display screen returns to the resolution before the multiple screens are accessed.

[0052] In some embodiments, when the display screen is replaced by a new one due to a problem, the optimal resolution of the newly connected display screen is set as the current resolution.

[0053] In some other embodiments, the display screen is not replaced or the number of display screens is not changed, but the current resolution is changed due to manual modification by the user.

[0054] In the above scenarios where the resolution is adjusted, in response to completion of the adjustment of the current resolution, the maximum zoom supported by the display screen at the current resolution is determined. Specifically, the maximum vertical zoom supported by the display screen is calculated according to the vertical resolution of the current resolution; the maximum horizontal zoom supported by the display screen is calculated according to the horizontal resolution of the current resolution; and the maximum zoom is determined according to the minimum value between the maximum vertical zoom and the maximum horizontal zoom.

[0055] Further, in some embodiments, when there are multiple display screens and the resolutions of the multiple display screens are different, the maximum zoom supported by the current resolution is calculated for each display screen respectively, and the minimum value among the maximum zooms supported by all the display screens is taken as the maximum zoom supported in the current mode.

[0056] After the resolution adjustment is completed, the maximum zoom supported by the current resolution is calculated, and the calculation process is as follows.

[0057] For each display screen, after the adjustment of the current resolution is completed, the maximum horizontal zoom and the maximum vertical zoom supported by the current resolution are calculated as follows.

[0058]

[0059]

[0060] wherein, is the maximum horizontal zoom, is the number of horizontal pixels corresponding to the current resolution; is the maximum vertical zoom, is the number of vertical pixels corresponding to the current resolution.

[0061] Further, the maximum zoom supported by the current resolution is determined according to the minimum value between the maximum horizontal zoom and the maximum vertical zoom. Specifically, the formula is as follows.

[0062]

[0063] When there are multiple display screens, the maximum zoom supported by each display screen at the current resolution is calculated respectively. The minimum value among the maximum scaling supported by all displays is taken as the maximum scaling that the current mode can support. The calculation formula is as follows:

[0064] )

[0065] in, This represents the maximum scaling supported by the current resolution of the i-th display screen.

[0066] like Figure 5 As shown, since the display provides zoom starting from 100% and increasing by a base of 25%, the calculated maximum zoom value may not be in the display's zoom list. Therefore, by rounding the maximum zoom down by a base of 0.25, we can obtain the zoom value closest to the calculated maximum zoom value. For example, a maximum zoom between 1.25 and 1.5 will be rounded down to 1.25, and a maximum zoom between 1.5 and 1.75 will be rounded down to 1.5. The specific formula is as follows:

[0067]

[0068] right Round down from the base of 0.25, with a range of [1.0, ...]. ].

[0069] in, This represents the maximum scaling supported at the current mode and resolution.

[0070] For example, in a scenario with only a single display screen, the adjusted current resolution of the display screen is "2048×1024", with 2048 horizontal pixels and 1024 vertical pixels. Based on the number of horizontal pixels, the maximum horizontal scaling is calculated as follows:

[0071]

[0072]

[0073] Therefore, the maximum scaling supported by the current resolution of this display is 1.333333. Next, 1.3333333 is rounded down to 1.25 using the base of 0.25. That is, the maximum scaling supported by the display at the current resolution is 125.

[0074] Next, in step S320, scaling is adjusted based on the comparison between the maximum scaling and the actual scaling.

[0075] After the maximum zoom supported under the current resolution is determined, the current zoom of the computing device is obtained, and the calculated maximum zoom is compared with the actual zoom of the computing device. If the current zoom of the computing device is greater than the calculated maximum zoom, the zoom of the computing device is set to the calculated maximum zoom.

[0076] Further, after the current resolution and zoom setting are determined, the determined current resolution and zoom setting are configured to the window pipe, and a broadcast signal is sent, so that each application on the desktop adjusts the window and other display according to the broadcast signal.

[0077] The method for adjusting zoom based on resolution provided by the present application aims at the problem of incomplete display of the desktop and application window caused by resolution change in the multi-screen or single-screen mode. In various scenarios causing resolution adjustment, the zoom is adjusted based on the adjusted resolution, so that the adjusted zoom matches the resolution, and each desktop application can be displayed completely, and the window display is ensured not to overflow in each scenario. Especially in the scenario of single screen changing into multi-screen, the resolutions of each display screen are compared, the optimal display mode and the resolutions of each screen are determined, and then the zoom is adjusted based on the resolutions, so that the optimal display effect is ensured in the multi-screen mode. In addition, when the multi-screen mode returns to the single-screen mode, the previous resolution configuration of the user can be automatically restored, and a good experience is provided for the user.

[0078] Embodiments of the present application also provide a device 600 for adjusting zoom based on resolution, which can perform each step of the method 300 for adjusting zoom based on resolution as described above. Next, the device 600 for adjusting zoom based on resolution is described in conjunction with Figure 6 FIG. 6.

[0084] According to an implementation manner of the present application, the current resolution adjustment comprises: the current resolution is adjusted due to the change in the number of display screens, and / or the current resolution is adjusted due to the change in the configuration of the display screen.

[0085] According to an implementation manner of the present application, when the number of display screens increases from one to a plurality, the current resolution corresponding to each of the plurality of display screens is determined according to a preset rule.

[0086] According to an implementation manner of the present application, when the resolutions supported by the plurality of display screens have the same resolution, the maximum value in the same resolution is determined as the current resolution corresponding to each of the plurality of display screens; and when the resolutions supported by the display screens do not have the same resolution, the current resolution of each display screen is determined as the optimal resolution of the display screen.

[0087] According to an implementation manner of the present application, when the number of display screens decreases from a plurality to one, the current resolution of the one display screen is restored to the resolution of the one display screen before the plurality of display screens are accessed.
