Thus, the phrases "in one embodiment," "in some embodiments," "in some other embodiments," "in some other embodiments," etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized.

[0046] EDID (Extended display identification data) is a standard device description field of HDMI (High Definition Multimedia Interface). It defines the description information of many HDMI devices. Generally speaking, the display signal output device will output the signal according to the recommended resolution described in EDID, so as to achieve a default optimal display effect.

[0047] Graphics cards are an important component of display signal output devices. Currently, high-end graphics cards are emerging in large numbers on the market, such as AMD's (Advanced Micro Devices) 6000 series, NVIDIA's 3000 series and 4000 series, etc. These graphics cards have the function of automatically adapting the output image according to the signal quality of the current data interface, and no longer use the data described in EDID as the only basis for judging the output signal.

[0048] The connection between display devices and high-end graphics cards generally requires the use of corresponding data cables. However, many display devices currently do not come with standard data cables, and users need to purchase the data cables themselves. The impedance specifications of different data cables vary. As a result, when using the above-mentioned graphics cards, the graphics cards will judge that the current signal quality is poor due to problems caused by impedance differences, and then output low-resolution video signals to the display device, causing users to misjudge and affecting the user experience.

[0049] Based on this, the embodiments of the present application propose a resolution adjustment method, apparatus, display device and computer-readable storage medium. In the resolution adjustment method, after the display signal output device is connected, the display device first receives the output signal of the display signal output device; then determines the current resolution based on the output signal; then obtains the optimal resolution, and compares the current resolution with the optimal resolution to obtain a comparison result; when the comparison result is that the current resolution is inconsistent with the optimal resolution, a resolution adjustment prompt is output to determine whether the user has the intention to adjust the resolution, so as to avoid the situation where the user deliberately adjusts the required resolution in advance; after receiving the confirmation adjustment instruction input by the user, the display device can adjust the current resolution to the optimal resolution, thereby eliminating the signal quality misjudgment caused by the display signal output device due to the difference in data line impedance, ensuring that the display device can still display at the most appropriate resolution, and improving the user experience of the display device.

[0050] The resolution adjustment method, apparatus, display device, and computer-readable storage medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the resolution adjustment method in the embodiments of the present application is described.

[0051] The present application embodiment provides a method for adjusting resolution. Figure 1 , Figure 1 A flowchart of a resolution adjustment method provided in an embodiment of the present application is provided. The resolution adjustment method can be applied to a display device, such as Figure 1 As shown, the resolution adjustment method provided in this embodiment includes steps S10 to S30.

[0052] Step S10, in response to the display signal output device being connected, receiving an output signal of the display signal output device;

[0053] It should be noted that in this embodiment, the executing entity is a display device, and a data interface for receiving video signals is provided on the display device. The display signal output device also has a data interface for outputting video signals. Generally, the types of data interfaces for transmitting video signals on the display device and the display signal output device are the same. Therefore, only a data cable with consistent connectors at both ends is needed to connect the two devices to realize video signal transmission. In the case of inconsistent data interface types, a video signal conversion cable can be used to enable the video signal to be successfully transmitted from the display signal output device to the display device.

[0054] As an example, see Figure 2In this embodiment, after the display signal output device establishes a connection with the display device through the data line, it is considered that the display signal output device is connected to the display device. At this time, the display device can receive the video signal (i.e., the output signal) output by the display signal output device.

[0055] As an example, in this embodiment, the data interface type used by the display device to receive the video signal can be VGA (Video Graphics Array), HDMI (High Definition Multimedia Interface) or DP (Display Port), etc.

[0056] Step S20, determining a current resolution based on the output signal;

[0057] It should be noted that after the display signal output device outputs the video signal to the display device, the display device will also send a feedback signal to the display signal output device, so that the display signal output device can determine whether there is a problem with the signal quality of the output signal received by the display device based on the feedback signal. However, due to the influence of the impedance difference between different data lines, the display signal output device may mistakenly believe that the signal quality does not meet the standard, thereby outputting a low-resolution video signal. Therefore, this embodiment needs to first determine the current resolution based on the output signal, and in subsequent steps, determine whether the output signal of the display signal output device reaches the most suitable resolution for the display device based on the current resolution.

[0058] As an example, the signal amplitude output by the display signal output device to the display device is 1V, but the signal amplitude fed back by the display device to the display signal output device is 0.8V. At this time, the display signal output device will determine that the signal quality is poor, and thus reduce the signal output frequency to increase the signal amplitude, resulting in a lower current resolution corresponding to the output signal.

[0059] Step S30, obtaining an optimal resolution, comparing the current resolution with the optimal resolution, and obtaining a comparison result;

[0060] It is understandable that in order to determine whether the display signal output device misjudges the signal quality and outputs a low-resolution signal, causing the current resolution of the display device to be lower than the optimal resolution, it is necessary to first obtain the optimal resolution.

[0061] As an example, one way to obtain the optimal resolution may be based on storage space, that is, obtaining it from a fixed file or a fixed data block. The advantage of this embodiment is that it is not limited by the data interface type.

[0062] As an example, another way to obtain the optimal resolution can be based on extended display identification data, that is, obtaining it through software parsing of the EDID (Extended display identification data) related to the data interface. Since EDID is not a standard device description field for all data interfaces, this embodiment is only applicable to some data interfaces.

[0063] As an example, this embodiment can determine whether the currently received timing (display resolution) matches the most appropriate timing of the display device in a normal working state by comparing the signal format or signal processing time of the signal.

[0064] In some feasible embodiments, the step of comparing the current resolution with the optimal resolution in step S30 to obtain a comparison result includes:

[0065] Step A30, comparing the signal format of the output signal with the signal format corresponding to the optimal resolution;

[0066] Step A31: When the signal format of the output signal is consistent with the signal format corresponding to the optimal resolution, a comparison result is obtained that the current resolution is consistent with the optimal resolution;

[0067] In step A32, when the signal format of the output signal is inconsistent with the signal format corresponding to the optimal resolution, a comparison result is obtained that the current resolution is inconsistent with the optimal resolution.

[0068] It is understandable that in this embodiment, the comparison result can be obtained by obtaining the signal format of the output signal from the display signal output device received by the current data interface and comparing it with the most appropriate display resolution (ie, optimal resolution) set in advance.

[0069] In some feasible embodiments, the step of comparing the current resolution with the optimal resolution in step S30 to obtain a comparison result includes:

[0070] Step B30, comparing the signal processing time of the output signal with the optimal processing time corresponding to the optimal resolution;

[0071] Step B31: When the signal processing time is consistent with the optimal processing time, a comparison result is obtained that the current resolution is consistent with the optimal resolution;

[0072] In step B32, when the signal processing time is inconsistent with the optimal processing time, a comparison result is obtained that the current resolution is inconsistent with the optimal resolution.

[0073] It can be understood that in this embodiment, the time from the output signal input to the display device to the signal stable output is used as the signal processing time of the output signal, and it is compared with the optimal processing time corresponding to the optimal resolution set in advance to obtain a comparison result.

[0074] In some feasible embodiments, before the above step S10, the resolution adjustment method may further include:

[0075] Step S01, recording the optimal resolution under normal working conditions;

[0076] Step S02: Save the optimal resolution in a storage space.

[0077] It is understandable that in order to avoid retesting the optimal resolution that the display device can adapt to when resolution comparison is required, and to achieve the effect of being able to directly obtain and use the optimal resolution when it is needed, it is necessary to debug the optimal resolution in advance and save the optimal resolution in the storage space of the display device in advance.

[0078] As an example, the optimal resolution may be saved in a fixed file.

[0079] As an example, the optimal resolution may be stored in a fixed data block.

[0080] Step S40: if the comparison result shows that the current resolution is inconsistent with the optimal resolution, output a resolution adjustment prompt;

[0081] It should be noted that this embodiment is a situation where the current resolution does not match the optimal resolution. The purpose of outputting the resolution adjustment prompt is to prompt the user whether resolution optimization is needed. On the one hand, it is to prompt the user that the impedance difference of the current data line has led to a lower resolution, and the resolution can be adjusted and optimized through subsequent operations; on the other hand, it is to take into account the situation where the user actively sets a lower current resolution and does not need to use the optimal resolution of the display device. For example: the user only needs the current resolution to reach 1080p (1920×1080 progressive scan), and the optimal resolution of the display device is 4K (the pixel value per horizontal line reaches or is close to 4096, regardless of the aspect ratio).

[0082] As an example, without considering whether the user actively lowers the current resolution, the resolution adjustment prompt may not be output and the resolution optimization adjustment may be performed directly. The advantage is that the processing efficiency is higher.

[0083] As an example, considering that the user actively lowers the current resolution, the next action is determined based on the user's subsequent operation instructions. This has the advantage of being more in line with the user's actual needs.

[0084] It is understandable that in another branch embodiment of step S40, that is, when the comparison result is that the current resolution is consistent with the optimal resolution, there is no need to output a resolution adjustment prompt, that is, the signal quality between the display signal output device and the display device does not affect the resolution and no adjustment is required.

[0085] Step S50 : In response to confirming the input of the adjustment instruction, adjusting the current resolution to the optimal resolution.

[0086] It is understandable that the confirmation adjustment instruction is a control instruction input by the user to the display device in response to the resolution adjustment prompt, adjusting the current resolution to the optimal resolution, that is, making the current resolution consistent with the optimal resolution.

[0087] As an example, see Figure 3 In this embodiment, the resolution adjustment prompt can be displayed in the display screen of the display device in the form of a prompt box. If the user selects "Yes", it is deemed to confirm the input of the adjustment instruction into the display device. At this time, the prompt box can be hidden, and the steps of adjusting the current resolution to the optimal resolution are executed; conversely, if the user selects "No", it is deemed to cancel the input of the adjustment instruction into the display device. At this time, the prompt box can be hidden, and the display screen continues to be displayed normally.

[0088] In some feasible embodiments, the step of adjusting the current resolution to the optimal resolution in step S50 may include:

[0089] Step S51 : adjusting the electrical performance parameters of the data interface connected to the display signal output device until the current resolution is consistent with the optimal resolution.

[0090] It should be noted that since the impedance difference of the data line is determined by its process and specifications and cannot be changed through software adjustment, the means adopted in this embodiment to eliminate the display signal output device's misjudgment of signal quality is to adjust the electrical performance parameters of the data interface. In related technologies, the electrical performance parameters of the data interface are generally fixed values ​​that have been locked at the factory, while in this embodiment, the parameters can be adjusted according to actual conditions. It is only necessary to poll the various electrical performance parameters in the data interface until the signal amplitude loss caused by the impedance difference of the data line can be offset. At this time, since the signal amplitude of the feedback signal received by the display signal output device is consistent with the signal amplitude of its output signal, there will be no misjudgment of poor signal quality, and the signal can be output at a normal signal output frequency, so that the current resolution can be consistent with the optimal resolution.

[0091] As an example, in this embodiment, the optimization logic of resolution adjustment is to continuously adjust the relevant electrical performance parameters of the digital channel port (i.e., data interface) so that the timing output by the display signal output device is consistent with the most appropriate timing of the display device under normal working conditions.

[0092] In some feasible embodiments, after the above step S50, the resolution adjustment method may further include:

[0093] Step S52: setting the current electrical performance parameters of the data interface as default electrical performance parameters.

[0094] It is understandable that since it takes a certain amount of time to adjust the current electrical performance parameters to adapt to the data interface, in order to avoid repeated adjustments during subsequent use, the current electrical performance parameters are saved and set as the default electrical performance parameters of the data interface, which can facilitate subsequent use.

[0095] As an example, in this embodiment, a step of prompting the user whether to save the current electrical performance parameters and set them as default electrical performance parameters may be added.

[0096] This embodiment provides a resolution adjustment method, in which, after a display signal output device is connected, the display device first receives the output signal of the display signal output device; then determines the current resolution based on the output signal; then obtains the optimal resolution, and compares the current resolution with the optimal resolution to obtain a comparison result; if the comparison result is that the current resolution is inconsistent with the optimal resolution, a resolution adjustment prompt is output to determine whether the user has the intention to adjust the resolution, so as to avoid the situation where the user deliberately adjusts the required resolution in advance; after receiving the confirmation adjustment instruction input by the user, the display device can adjust the current resolution to the optimal resolution, thereby eliminating the signal quality misjudgment caused by the display signal output device due to the difference in data line impedance, ensuring that the display device can still display at the most appropriate resolution, and improving the user experience of the display device.

[0097] In addition, the embodiment of the present application also proposes a resolution adjustment device, referring to Figure 4 , Figure 4 A schematic diagram of a resolution adjustment device according to an embodiment of the present application is shown in FIG.

[0104] In some feasible embodiments, the adjustment module 500 is further configured to set current electrical performance parameters of the data interface as default electrical performance parameters.

[0107] In some feasible embodiments, the comparison module 300 is further configured to obtain the optimal resolution based on storage space; or, to obtain the optimal resolution based on extended display identification data.

[0108] In some feasible embodiments, the comparison module 300 is further configured to compare the signal format of the output signal with the signal format corresponding to the optimal resolution;

[0109] When the signal format of the output signal is consistent with the signal format corresponding to the optimal resolution, a comparison result is obtained that the current resolution is consistent with the optimal resolution;

[0110] In a case where the signal format of the output signal is inconsistent with the signal format corresponding to the optimal resolution, a comparison result is obtained that the current resolution is inconsistent with the optimal resolution.

[0113] When the signal processing time is inconsistent with the optimal processing time, the comparison result is that the current resolution is inconsistent with the optimal resolution.
