[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Method Embodiment

[0062] Reference Figure 1 , shows a flowchart of a method for setting resolution according to an embodiment of the present invention, the method is applied to an electronic device, and the method may specifically include the following steps:

[0063] Step 101: when an event that an external display is connected to a display port of the electronic device is detected, obtaining status information of the external display;

[0064] Step 102: Filter the status information to obtain first resolution information of the external display;

[0065] Step 103: if the first resolution information does not exist in the configuration information built into the electronic device, adjust the configuration information according to the first resolution information to add the first resolution information to the configuration information;

[0066] Step 104: Set a target resolution corresponding to the display port according to the first resolution information.

[0067] An embodiment of the present invention provides a method for setting resolution, which can be applied to an electronic device having a display output function. Figure 2 , shows a schematic diagram of the architecture of an application scenario in an embodiment of the present invention. Figure 2 As shown, the electronic device is connected to the external display via a connecting cable. It is understandable that one end of the connecting cable is inserted into the display port of the electronic device, and the other end is inserted into the input port of the external display. The display port may include an HDMI interface, a video graphics array (VGA) interface, a digital video interface standard (Display Port, DP) interface, and the like. For example, the two ends of the HDMI cable are respectively inserted into the HDMI interface of the electronic device and the input port of the external display. Among them, the electronic device may include but is not limited to a server, a computer host, a personal computer, a television, a TV box, a DVD player, an amplifier, and the like. Further, the electronic device may be equipped with an embedded operating system, such as Linux, uClinux, VxWorks, and the like, and the resolution setting method provided by the embodiment of the present invention is implemented by the embedded operating system, so as to output image information according to the set target resolution and display it in the external display.

[0068] If it is detected that an external display is connected to the display port, the status information of the external display can be obtained, and the obtained status information can be filtered to obtain the first resolution information of the external display. The status information includes the resolution information supported by the external display, and the first resolution information is any resolution supported by the external display. In a possible application scenario, the first resolution information includes the optimal resolution information that the external display can support. The configuration information is used to indicate the resolution supported by the electronic device.

[0069] It is understandable that the electronic device can obtain the status information of the external display in a variety of ways, and the embodiment of the present invention does not specifically limit this. For example, the electronic device can obtain the status information of the connected external display with the help of resolution test tools such as Mode Test, Monitor Test, LCD Test, etc.

[0070] The first resolution information of the external display is compared with the built-in configuration information of the electronic device. If the first resolution information of the external display does not exist in the built-in configuration information of the electronic device, it means that the electronic device does not support the first resolution information at this time. In this case, the configuration information of the electronic device can be adjusted according to the first resolution information, that is, the first resolution information is added to the configuration information, and the electronic device is adapted to the first resolution information supported by the external display, so that the electronic device can output image information with the first resolution information and display it on the external display. It should be noted that the configuration information of the electronic device is usually saved in the configuration file of the electronic device, so the configuration file of the electronic device can be modified to add the first resolution information to its configuration information. Exemplarily, the configuration information of the electronic device can be modified by an extended configuration tool, such as xrandr, xorg, etc., and the first resolution information of the external display can be added to its built-in configuration information.

[0071] If the first resolution information of the external display is present in the built-in configuration information of the electronic device, it means that the electronic device supports the first resolution information. In this case, the target resolution corresponding to the display port connected to the external display can be directly set according to the first resolution information. Then, the image information is output at the target resolution and displayed on the external display.

[0072] Optionally, the method further includes: acquiring image information to be displayed; and displaying the image information on the external display according to the target resolution.

[0073] The image information may include but is not limited to video streams, pictures, animations, etc. The electronic device may output the image information to an external display through a display port, and display the image information on the external display according to a target resolution.

[0074] As an example, assume that an external display is connected to an electronic device through an HDMI port, the first resolution information of the external display is 1024*820, and the built-in configuration information of the electronic device includes 1024*768, 1152*864, and 800*600. Obviously, the first resolution information 1024*820 does not exist in the configuration information. In this case, the configuration information of the electronic device can be modified through xrandr to add the first resolution information of the external display to its built-in configuration information. After the modification, the configuration information of the electronic device includes the first resolution information 1024*820 supported by the external display, and 1024*820 is directly set as the target resolution corresponding to the display port HDMI, so that the image information is output and displayed to the external display through the HDMI port with a resolution of 1024*820.

[0075] It can be understood that the resolution setting method provided in the embodiment of the present invention can also be used to set the target resolution and perform display control for each external display separately when the electronic device is connected to multiple external displays. Specifically, for each external display connected to the display port, its corresponding target resolution is set according to steps 101 to 103, and then the image information to be displayed is output from the display port to the external display according to the target resolution. The target resolution corresponding to each external display can be the same or different. Furthermore, based on the connection relationship between the external display and the display port, a mapping relationship between the external display and the display port, as well as a mapping relationship between the display port and the target resolution can be established, so as to accurately output the image information to the corresponding external display according to the target resolution, thereby realizing independent control of each external display.

[0076] As an example, assume that the external display X0 is connected to the electronic device through the display port HDMI-0, the external display X1 is connected to the electronic device through the display port HDMI-1, and the external display X2 is connected to the electronic device through the display port HDMI-2, wherein the first resolution information of the external display X0 is 1024*820, the first resolution information of the external display X1 is 1152*864, the first resolution information of the external display X2 is 1280*1024, and the built-in configuration information of the electronic device includes 1024*768, 1152*864, and 800*600. For the external display X0, perform steps 101 and 102, add 1024*820 to the configuration information of the electronic device, and then determine 1024*820 as the target resolution corresponding to the display port HDMI-0. For the external display X1, the configuration information includes the first resolution information 1152*864 of the external display X1, so 1152*864 can be directly determined as the target resolution corresponding to the display port HDMI-1. For the external display X2, execute steps 101 and 102, add 1280*1024 to the configuration information of the electronic device, and then determine 1280*1024 as the target resolution corresponding to the display port HDMI-2. Finally, output the image information to be displayed in each external display through the display port and target resolution corresponding to each external display.

[0077] The resolution setting method provided in an embodiment of the present invention can adaptively adjust the configuration information of the electronic device to adapt the target resolution for the connected external display when the resolution of the electronic device and the connected external display do not match. This can effectively avoid problems such as image display frame loss caused by the mismatch between the resolution supported by the electronic device and the external display, and is conducive to improving the image display effect.

[0078] In an optional embodiment of the present invention, the electronic device includes a first process; when an event that an external display is connected to a display port of the electronic device is detected in step 101, obtaining status information of the external display includes:

[0079] When an event that an external display is connected to the display port is detected, the first process is run; the first process is used to obtain status information of the external display.

[0080] In an embodiment of the present invention, the state information of the connected external display can be detected by a first process, and the detected state information can be filtered to obtain the first resolution information of the external display. The first process can be a resolution detection process, such as Mode Test, Monitor Test, and so on.

[0081] Optionally, the electronic device further includes a second process and a third process; in step 102, when the first resolution information does not exist in the configuration information built into the electronic device, adjusting the configuration information according to the first resolution information to add the first resolution information to the configuration information includes:

[0082] Step S11: the second process receives a first bus signal sent by the first process; the first bus signal is used to indicate the first resolution information;

[0083] Step S12: the second process compares the first resolution information with the configuration information built into the electronic device;

[0084] Step S13: When the first resolution information does not exist in the configuration information, the second process sends the first bus signal to the third process to trigger the third process to add the first resolution information to the configuration information.

[0085] In the embodiment of the present invention, adaptive setting of resolution can be achieved through three processes in a coordinated manner.

[0086] Specifically, the first process can detect the external display access event, and when it is detected that the external display is connected to the display port, the external display status information is obtained and the first resolution information is filtered out. The first process transmits the obtained first resolution information to the second process.

[0087] It should be noted that processes can communicate with each other through a message bus system (Desktop-Bus, D-Bus). Exemplarily, the first process can transmit the first resolution information of the external display to the second process through a first bus signal. It can be understood that the first bus signal is a bus signal corresponding to the first resolution information. After determining the first resolution information, the first process converts the first resolution information into a first bus signal and sends it to the second process.

[0088] After receiving the first resolution information, the second process compares the first resolution information with the configuration information built into the electronic device. If the first resolution information of the external display does not exist in the configuration information, the second process can transmit the first resolution information to the third process by sending a first bus signal to the third process.

[0089] After receiving the first bus signal, the third process modifies the configuration information of the electronic device and adds the first resolution information to the configuration information so that the second process can set the target resolution.

[0090] Optionally, setting a target resolution corresponding to the display port according to the first resolution information includes:

[0091] In a case where the first resolution information exists in the configuration information, the second process is run, and the second process is used to set a target resolution corresponding to the display port according to the first resolution information.

[0092] If the configuration information contains the first resolution information of the external display, the second process can directly set the target resolution corresponding to the display port according to the first resolution information without triggering the third process.

[0093] In an optional embodiment of the present invention, the method further includes:

[0094] Step S21: the second process sends a second bus signal to the first process; the second bus signal is used to indicate that the second process has received the first bus signal;

[0095] Step S22: The first process continues to send the first bus signal to the second process until it receives the second bus signal and stops.

[0096] In the embodiment of the present invention, a signal handshake protection mechanism may be used between processes to communicate, so as to prevent abnormal resolution setting caused by abnormal conditions such as information not being sent or not being received normally after being sent.

[0097] Exemplarily, after acquiring the first resolution information of the connected external display, the first process may continue to send the first bus signal to the second process (according to a preset period). After receiving the first bus signal, the second process feeds back a second bus signal to the first process to indicate that the first bus signal has been received. When the first process receives the second bus signal, it may no longer send the first bus signal. If the first process does not receive the second bus signal, the first bus signal is repeatedly sent to the second process to ensure that the second process receives the first bus signal normally and that subsequent processing can proceed normally.

[0098] Optionally, the method further comprises:

[0099] Step S31: When the third process successfully adds the first resolution information to the configuration information, the third process sends a third bus signal to the second process; the third bus signal is used to indicate that the first resolution information has been added to the configuration information;

[0100] Step S32: When the second process receives the third bus signal, the second process sets the target resolution corresponding to the display port according to the first resolution information.

[0101] After the third process receives the first bus signal sent by the second process, it modifies the configuration information of the electronic device, adds the first resolution information to the configuration information, and after completing the addition of the first resolution information, sends a third bus signal to the second process to inform the second process that the first resolution information has been added to the configuration information.

[0102] After receiving the third bus signal, the second process sets the target resolution corresponding to the display port connected to the external display according to the first resolution information, and then outputs the image information according to the set target resolution and displays it on the external display.

[0103] Reference Figure 3 , shows a resolution setting flow chart provided by an embodiment of the present invention. Figure 3 As shown, the external display X0 is connected to the electronic device via the display port HDMI-0, the external display X1 is connected to the electronic device via the display port HDMI-1, and the external display X2 is connected to the electronic device via the display port HDMI-2. Among them, the first resolution information of the external display X0 is 1024*820, the first resolution information of the external display X1 is 1152*864, and the first resolution information of the external display X2 is 1280*1024. The built-in configuration information of the electronic device includes 1024*768, 1152*864, and 800*600. Figure 3 Taking as an example, the specific processing procedure of the first process, the second process and the third process in the embodiment of the present invention cooperating to realize the adaptive setting of the resolution is described.

[0104] When the first process detects that an external display is connected to the display port HDMI-0, it obtains the current status information of the external display X0, and filters the obtained status information to obtain the first resolution information of the external display X0 as 1024*820. Then, the first resolution information is sent to the second process through the first bus signal.

[0105] After receiving the first resolution information, the second process compares the first resolution information with the configuration information built into the electronic device. At this time, the first resolution information 1024*820 of the external display X0 does not exist in the configuration information. Therefore, the second process sends a first bus signal to the third process to pass the first resolution information to the third process. In addition, the second process feeds back a second bus signal to the first process to inform the first process that the first bus signal has been received.

[0106] After receiving the first bus signal sent by the second process, the third process modifies the configuration information of the electronic device, adds the first resolution information 1024*820 to the configuration information, and after completing the addition of the first resolution information, sends the third bus signal to the second process.

[0107] After receiving the third bus signal, the second process sets the target resolution corresponding to the display port HDMI-0 to 1024*820.

[0108] When the first process detects that an external display is connected to the display port HDMI-1, it obtains the current status information of the external display X1, and filters the obtained status information to obtain the first resolution information of the external display X1 as 1152*864. Then, the first resolution information is sent to the second process through the first bus signal.

[0109] After receiving the first resolution information, the second process compares the first resolution information with the configuration information built into the electronic device. In addition, the second process feeds back a second bus signal to the first process to inform the first process that the first bus signal has been received. At this time, the configuration information contains the first resolution information 1152*864 of the external display X1. Therefore, the second process can directly determine 1152*864 as the target resolution corresponding to the display port HDMI-1 without triggering the third process.

[0110] The processing flow after the external display X2 is connected can refer to the corresponding processing process of the external display X0, and the embodiment of the present invention will not be further described here.

[0111] Finally, the image information to be displayed on each external display can be output through the display port corresponding to each external display and the target resolution.

[0112] After the above processing, the resolution can be set individually for each external display, realizing adaptive setting of resolution and independent display control.

[0113] In summary, an embodiment of the present invention provides a resolution setting method, which can adaptively adjust the configuration information of the electronic device when the resolution of the electronic device and the connected external display do not match, and adapt the target resolution for the connected external display. This can effectively avoid problems such as image display frame loss caused by the mismatch between the resolution supported by the electronic device and the external display, and is conducive to improving the image display effect.
