The invention provides a multi-screen display method, a multi-screen display device, host equipment and a multi-screen display system, and the method comprises the steps: receiving a configuration request of an external display, the configuration request comprising a target video output type and a target video resolution; according to the configuration request, configuring the resolution of the display card interface corresponding to the target video output type as a target video resolution; comparing the target video resolution with the main display resolution of the main display to obtain acomparison result; and projecting the target interval image of the main display to an external display based on the comparison result. According to the invention, a secondary display receives a configuration request, the graphics card interface is configured according to the configuration request; flexible configuration of video card interfaces with different resolutions is realized, the target interval image of the main display image of the main display is projected to the external display through the comparison result of the target video resolution and the main display resolution of the maindisplay, the method and the device can be adapted to external display equipment with different resolutions, and multi-screen display is realized.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a multi-screen display method, a multi-screen display device, a host device and a multi-screen display system. Background technique [0002] The Linux operating system is a freely disseminated and free Unix-like operating system. In the Linux system, there is already a mature video output configuration tool xrandr, which can directly configure multi-screen and multi-resolution output display based on the libX11 library under the Linux system; In terms of display hot-swapping, there is currently a tool srandrd based on libX11 in the Linux system to monitor the video interface status of the graphics card in real time, and implement hot-swapping related actions according to user-configured scripts; and in terms of user visualization operations, QT is a Very good development platform, which integrates rich control resources, easy to develop, very friendly interface display...
