8. The method of automatically adjusting an output screen of a signal source according to claim 1, wherein the signal source retrieving the post-setup EDID of the all-in-one machine comprises:
the signal source detects the HPD signal on the all-in-one machine in real time, and when the HPD signal is detected to be changed from low level to high level, the signal source reads the set EDID on the all-in-one machine again.
9. An apparatus for automatically adjusting output pictures of a signal source based on a one-piece machine, the apparatus comprising:
a signal output module: the signal source is used for obtaining EDID of the all-in-one machine when the all-in-one machine is accessed to the signal source, and the signal source outputs a corresponding timing signal to the all-in-one machine based on the EDID;
a judging module: the all-in-one machine is used for judging whether the timing signal is stable or not based on the SOC end after receiving the timing signal;
setting a module: the integrated machine is used for setting the recommended resolution in the EDID based on a system interface of the integrated machine when the timing signal is not stable, and obtaining the set EDID;
a re-output module: and the signal source is used for obtaining the EDID of the all-in-one machine after setting again and outputting a corresponding timing signal to the all-in-one machine until the timing signal is stable or the recommended resolution in the EDID is the lowest recommended resolution.
10. A system for automatically adjusting output pictures of a signal source based on an all-in-one machine is characterized by comprising all-in-one machine equipment and a signal source end; wherein the all-in-one machine is connected with the signal source terminal based on an HDMI interface or a DP interface, and the system is configured to perform the method for automatically adjusting the output picture of the signal source according to any one of claims 1 to 8.
