Embodiment Construction

[0010] Below in conjunction with specific embodiment, further illustrate the present invention, it should be understood that following specific embodiment is only for illustrating the present invention and is not intended to limit the scope of the present invention, after reading the present invention, those skilled in the art will understand various aspects of the present invention All modifications of the valence form fall within the scope defined by the appended claims of the present application.

[0011] The invention discloses a method for burning port expansion display identification data, and the method for burning port expansion display identification data can be used for port data burning on a display. The ports generally provided on the existing display are D-SUB port, DVI port and HDMI port.

[0012] This method is realized in that the preset extended display identification data is stored in the flash memory of the display, and one of the ports (which can be a D-SUB...

Abstract

The invention relates to a method for programming port extended display identification data, which comprises the steps of: firstly programming formal extended display identification data for one port; automatically programming preset extended display identification data when other ports are electrified for the first time; and then, reading out the information of the formal extended display identification data programmed on the port and updating the information to the preset extended display identification data of the information so as to convert the preset extended display identification data into the formal extended display identification data. Thereby, the mode of programming the port extended display identification data for all ports by connecting a data line is not needed so that the efficiency of programming the port extended display identification data is higher and more convenient.

Description

technical field [0001] The invention relates to a programming method, in particular to a method for expanding display identification data of a programming port of a display. Background technique [0002] EDID (Extended Display Identification Data, Extended Display Identification Data) is a Video Electronics Standards Association (VESA) standard data format that contains parameters about the display and its performance, including supplier information, maximum image size, color settings, manufacturer presets settings, limits for the frequency range, and strings for the display name and serial number. [0003] Now when monitors are mass-produced, each port (analog port, digital port, HDMI port, etc.) needs to input EDID. EDID contains the communication information between the monitor and the PC graphics card. Take the HDMI port as an example. , the monitor will not display normally. [0004] In the prior art, the method of inputting EDID to the port is to connect the data lin...
