Problems solved by technology

[0005] However, in the prior art, there are still many displays that cannot provide correct EDID
When the video output port of the electronic device is connected to these monitors, since the resolution information supported by the monitor cannot be known, when the resolution of the image output by the electronic device is not supported by the monitor, the monitor still cannot display normally
Usually, in this case, users can only avoid this problem by reinstalling the operating system, etc.

Abstract

The invention discloses a video signal processing method and electronic equipment. The video signal processing method comprises the steps: when the starting process of an operation system of electronic equipment is triggered, acquiring a first video signal, with a first resolution, output from a display chip of the electronic equipment; converting the first video signal into a second video signal with a second resolution; and outputting the second video signal to a display unit, wherein the display unit at least supports the video signal with the second resolution. The video signal processing method and the electronic equipment can adjust the resolution of the output video signals before the operation system is fully started so as to enable the resolution of the video signals output from the electronic equipment to be supported by a display, and do not need reinstallation of the operation system.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a video signal processing method and electronic equipment. Background technique [0002] With the continuous development of electronic equipment, the image resolution supported by the electronic equipment is also getting higher and higher. For example, the physical resolution of the screen of a 4K TV launched on the market can reach 3840×2160 pixels. [0003] However, a considerable part of displays currently in use still support relatively low image resolutions, for example, only 1024×768 pixels are supported. In practical applications, if the resolution of the image output by the electronic device that outputs the video signal is greater than the resolution supported by the display, the display cannot display the image, and the display will appear black screen and the like. [0004] In the prior art, in order to avoid the occurrence of the above situation, the electronic device...
