Abstract

The invention provides a control method and electronic equipment. Hot plug detection is carried out on a multimedia interface of the electronic equipment, when a detection result indicates that a multimedia data line is connected into the multimedia interface, namely the electronic equipment is connected into projection equipment, a signal conversion device for controlling the electronic equipment is in a power supply state, and after the electronic equipment enters an equipment display mode for a period of time, a projection display mode can be automatically switched into through a hot key mode without entering an operation interface and manually starting the projection display mode. The control method improves working efficiency and is more practical.

Description

technical field [0001] This application mainly relates to the field of multimedia applications, and more specifically relates to a control method and electronic equipment. Background technique [0002] At present, in application scenarios such as conferences and teaching, in order to enable all participants to watch the explanation content, the multimedia interface of electronic devices such as notebook computers and desktop computers is usually connected to a projection device through a multimedia data cable. The hotkey (such as win+P) mode controls the electronic device to switch from the device display mode to the projection display mode, so that the display information of the electronic device is enlarged and projected through the projection device. [0003] Wherein, the electronic equipment usually utilizes a signal conversion device to convert HDMI (High Definition Multimedia Interface, high-definition multimedia interface) signals into LVDS (Low-Voltage Differential S...
