Abstract: Disclosed are a display apparatus and a method. The method includes: in response to detecting that an external device is connected via an external device interface of the display apparatus, obtaining SPD data from the external device; reading device identification information from the SPD data; in response to the device model being found in a device management list pre-stored in the display apparatus, switching a version of the transmission protocol to a version of the transmission protocol matched with the device model stored in the device management list; in response to the device mode being not found in the device management list, detecting a tag for indicating a new version function; in response to the tag for indicating the new version function being detected, switching the version of the transmission protocol to the first version; otherwise, switching the version of the transmission protocol to the second version.

Abstract: Disclosed in the present application are a display apparatus and a processing method. According to the method, a data stream from the external device in connection with the display apparatus is received; a device information frame in the data stream is obtained, where the device information frame is a data frame generated by the external device according to a basic transmission protocol between the external device and the display apparatus; marker bits in the device information frame are traversed; in response to the external device supporting the automatic control protocol, a play mode is switched according to usage scenario information added in the data stream; and in response to the external device not supporting the automatic control protocol, a play mode is switched according to a device type of the external device.

Abstract: Disclosed are a display apparatus and a method for the display apparatus. The method includes: obtaining device information of an external device in connection with the display apparatus; parsing a variable frame rate mode supported by the external device from the device information by traversing a flag bit field in the device information; controlling the display to present an interactive menu, and receiving an interactive operation from a user through the interactive menu, wherein the interactive menu includes at least one option of variable frame rate modes; setting a display parameter of the display apparatus according to a first variable frame rate mode indicated by the interaction operation.
