摘要： The present application belongs to the field of machine vision. Disclosed are a control method for a display apparatus, a display apparatus, a device and a computer storage medium. The method comprises: a display apparatus receiving at least two pieces of data to be displayed, which are respectively sent by at least two terminals, wherein the at least two pieces of data to be displayed comprise screen mirroring data and state parameters of the terminals; and then, displaying the state parameters, and performing screen mirroring display on the basis of the screen mirroring data. In this way, various pieces of data sent by at least two terminals can be displayed by means of a display apparatus, and the displayed data is relatively rich, such that the problem in the related art of data displayed by a display apparatus being relatively simple can be solved, thereby achieving the effect of improving the diversity of data displayed by a display apparatus.
