Abstract

The invention discloses an EDID data generation method, the EDID data generation method is applied to a display device, and the EDID data generation method comprises the following steps: after the display device is started up, analyzing a preset configuration file, and obtaining parameter values of parameters in the configuration file; converting the parameter value into a numerical value of a field corresponding to extended display identifier (EDID) data; and synthesizing the converted numerical values of the fields into complete EDID data, and sending the complete EDID data to a port of thedisplay device, so that a signal source input from the port is matched with the display device for output. The invention further discloses a display device and a computer readable storage medium. According to the method, the numerical value content of the EDID data is changed into the parameter value in the configuration file, so that the EDID data maintenance efficiency is improved, and meanwhile, the EDID data modification difficulty is reduced.

Description

Technical field [0001] The present invention relates to the field of multimedia display technology, and in particular to a method for generating EDID data, a display device and a computer-readable storage medium. Background technique [0002] Current display devices such as monitors, TVs, etc. have HDMI, VGA, or DVI ports. Usually, each signal input port needs to retain a copy of extended display identification data (EDID). This EDID data can be stored in the program It is initialized during system startup. It is more common to have an EEPROM for each port to save the EDID data. This EEPROM is only 256bytes in size. An external device such as a DVD player will read the EDID data through the HDMI DDC channel when the port such as HDMI is hot plugged. EDID mainly defines the image resolution supported by the display device, supported sound formats, sound channels, and 3D, etc. Its purpose is to tell the external device the features supported by the display device, and let the exte...
