A method for fully-automatically aligning a quality of an image, comprising:
- disposing a first memory and a third memory in a multi-sync display, wherein:
- the first memory is used for storing a first computer host identification (ID), a display ID, a counter ID, a color level flag, a preset color level alignment value, a plurality of preset timing flags, a plurality of preset timing parameters respectively corresponding to the preset timing flags, and a plurality of preset timing alignment values respectively corresponding to the preset timing parameters, and reserving a memory space to expand a plurality of self-set timing flags, a plurality of self-set timing parameters respectively corresponding to the self-set timing flags, and a plurality of self-set timing alignment values respectively corresponding to the self-set timing parameters, so as to form a first timing data table;
- and
- the third memory is used for temporarily storing a reference timing parameter, a current timing parameter, and a current timing alignment value, so as to form a second timing data table, and the reference timing parameter is a previous timing parameter or an invalid timing parameter;
- disposing a second memory in a video graphic array (VGA) display card of a computer system or a computer host of the computer system, wherein the second memory is used for storing a second computer host ID, and the VGA display card is used for providing an image signal and a horizontal and vertical synchronization signal;
- detecting at least three detection mechanisms as follows, wherein:
- a first detection mechanism in the at least three detection mechanisms is that detecting whether the multi-sync display under a power-on state is connected to the VGA display card in the computer system under the power-on state through a display cable;
- a second detection mechanism in the at least three detection mechanisms is that detecting whether a cold start has occurred for the multi-sync display connected to the VGA display card in the computer system under the power-on state through the display cable;
- a third detection mechanism in the at least three detection mechanisms is that detecting whether a cold or hot start has occurred for the computer system with the VGA display card connected to the multi-sync display under the power-on state through the display cable;
- and when one of the three detection mechanisms has occurred, providing a detecting trigger signal;
- executing a system control program through the multi-sync display, so when the detecting trigger signal has transformed from a first state to a second state, whether the first computer host ID matches with the second computer host ID is determined through an information channel;
- and
- responding to a request of the system control program by executing a device driving program through the computer system, so when the first and second computer host IDs are determined as different, a color level automatic alignment and a timing automatic alignment are performed to the image signal and/or the horizontal and vertical synchronization signal provided by the VGA display card in the computer system, so as to configure states of the color level flag, the preset timing flags, and the self-set timing flags, and obtain a color level automatic alignment value and a timing automatic alignment value to align a quality of an image displayed on a panel display module of the multi-sync display,
- wherein when the detecting trigger signal has transformed from the first state to the second state, the method executes the following steps:
- sending a read command to the computer system through the information channel, so when the computer system receives the read command, the computer system responds to the read command by sending the second computer host ID back to the multi-sync display through the information channel;
- and
- comparing whether the second computer host ID sent back by the computer system matches with the first computer host ID.
