In an embodiment of the present invention, the display specification information of the first display 230 includes information such as the display number of the first display 230, the maximum displayable resolution, and the like. In an embodiment of the present invention, the first display may be a High-Definition Multimedia Interface (HDMI) display, a Display Port display, a Mobile High-Definition Link (MHL) display, or Analog display (Analog R/G/B).

When the processor 226 obtains the display specification information of the first display 230, the processor 226 can set the current display specification information as the display specification information of the first display 230. After the processor 226 finishes setting the current display specification information, the computer 210 can output the appropriate first output image data D1 to the image bridge device 220 according to the current display specification information, and the image bridge device 220 outputs the second output image data D2 to make the first The display 230 is capable of displaying an image.

The user can also adjust the image quality to be output through the computer 210, for example, to improve the resolution of the image, and the operating system of the computer 210 records the parameters adjusted by the user according to the display number of the display specification information. Therefore, each time the first display 230 is coupled to the image bridge device 220, since the display number of the current display specification information set by the processor 226 is the same, the computer 210 can identify the display number according to the current display specification information. A display 230 outputs image data according to a parameter setting previously adjusted by the user.

When the processor 226 is unable to obtain the display specification information of the first display 230, the processor 226 may set the current display specification information as the preset display specification information.

In one embodiment of the present invention, the user can remove the first display 230 from the image bridge device 220 and the other second display 240 to the image bridge device 220. At this time, if the image bridging device 220 cannot obtain the display specification information of the second display 240, the image bridging device 220 still sets the current display specification information as the preset display specification information. Since the current display specification information and the display number thereof obtained by the computer 210 have not changed, the computer 210 misinterprets the second display 240 as the first display 230 and according to the parameters set by the previous user for the first display 230. Output image data with high resolution, that is, image data with a resolution of 1920x1080. If the highest resolution that the second display 240 can support is only 1280x720, the second display 240 will not be able to display the image.

In order to solve the problem that the computer 210 treats different displays as the same display and outputs image information that does not conform to the display specifications so that the display cannot display images, the user can generate a level change through the operating system, BIOS or other software components of the computer 210. The input control signal 214 is triggered to the input control terminal 224 of the image bridge device 220, and the level change can be generated by the external contact button, the external toggle switch, and the external device to trigger the input control signal E1 to the input control terminal 224 of the image bridge device 220. . When the processor 226 receives the input control signal E1, the processor 226 can update the preset. The display number of the display specification information, such as, but not limited to, the display number of the preset display specification information is incremented by one; then the processor 226 restarts the connection with the second display 240. In this way, if the processor 226 fails to obtain the display specification information of the second display 240 when the connection is restarted, the processor 226 sets the current display specification information to the updated preset display specification information, due to the updated information. The display number of the preset display specification information is different from the display number of the original preset display specification information, so the computer 210 outputs the image information by using the preset display specification information, and does not output the high according to the parameter set by the user before. Resolution image information. In another embodiment of the present invention, the input control terminal 224 of the image bridging device 220 can also be coupled to an external button, and the user can trigger the output control signal E1 through the external button.

Since the processor 226 can update the display number of the preset display specification information according to the input control signal, when the second display 240 cannot display the image correctly, the user can control the signal through the trigger so that the computer 210 does not move the second display 240. It is regarded as the first display 230, and can output image data conforming to the specifications of the second display 240. In this way, the image bridge device 220 or the image output system 200 can solve the problem that the computer cannot view the display specification information of the display, and the computer regards the different displays as the same display, and the image cannot be correctly displayed.

In addition, in FIG. 3, the image bridging device 220 includes a first memory M1, and the first memory M1 can be used to store current display specification information and preset display specification information set by the processor 226. However, the present invention is not limited thereto; FIG. 4 is a schematic view of the image bridging device 220' of another embodiment of the present invention.
