Method and device of dynamically adjusting resolution

A device for dynamically adjusting resolution, comprising:

• one or more processors;
• and
• one or more computer storage media for storing one or more computer-readable instructions, wherein the processor is configured to drive the computer storage media to execute the following tasks:
• performing a ratio reduction operation on a native resolution of a display screen according to a ratio data command to obtain a target resolution when receiving the ratio data command;
• replacing the native resolution at a resolution storage address in an extended display identification data (EDID) with the target resolution to allow the target resolution to be read by a source device;
• receiving image data, wherein the image data is generated by the source device according to the target resolution;
• performing a ratio increase operation on the target resolution according to the ratio data command to obtain a screen resolution;
• and
• setting the native resolution of the display screen to the screen resolution to display the image data;
• wherein the processor further executes the following tasks:
• storing the native resolution in another storage location in the EDID;
• and
• replacing the target resolution in the resolution storage address with the native resolution when the source device cannot read the target resolution.
