Problems solved by technology

However, since the image source will be based on the extended display identification data (Extended Display Identification Data, EDID) of the display screen to pass through the transmission port of the display screen (such as High Definition Multimedia Interface (HDMI) or digital video interface ( Digital Visual Interface, DVI) transmission port, etc.) provide images that meet the best resolution of the screen to display on the display screen, so no matter which layout arrangement the display screen adopts, the resolution of the sub-display layout (less than the screen The optimal resolution of the screen) cannot match the resolution of the image transmitted from the image source, resulting in display problems such as unclear picture or proportional distortion

Abstract

The invention provides a screen resolution adjusting method, which is applied to image display of a display device and comprises the following steps of: providing a layout menu by the display device to obtain a screen layout configuration consisting of a plurality of display layouts; the display device performs resolution parameter setting for each display layout according to the screen layout configuration and a screen native resolution parameter of the display device. The display device sets and modifies an original product identification code and a screen native resolution parameter of the display device according to each resolution parameter to generate an updated product identification code and a plurality of updated resolution parameters, and each image source reads the updated product identification code and the corresponding updated resolution parameter. And the corresponding transmission port outputs the image conforming to the updated resolution parameter to the corresponding display layout for display.

Description

technical field [0001] The invention relates to a method for adjusting screen resolution and a display device thereof, in particular to a method for adjusting screen resolution and a display device thereof for modifying native screen resolution parameters of the display device according to screen layout configuration. Background technique [0002] Generally speaking, in the actual application of the display screen, in order to facilitate the user to multitask and perform different activities (such as performing document processing while watching a movie), the display screen usually has a multi-layout display function (such as a parent-in-picture display layout (Picture in Picture, PIP) or display layout side by side (Picture by Picture, PBP) function). The so-called mother-in-picture display layout function is to display the image transmitted from one image source on the main display layout that meets the set resolution of the screen (usually the best resolution of the scree...
