In order to improve the limitation that a real display must be connected when the display output of a display card is displayed, a fake display appears in the market to replace the real display, the fake display realizes all functions of the real display through remote desktop access service, a computer reduces the occupation of the display, and the space and the resources are saved.
However, false displays present an abnormal lockout risk. The false display needs to be installed on an output interface of the display card to replace the positive display; in the installation process, due to different installation methods of operators, the false display can not be installed in place and cannot be locked normally; in addition, the false display may interfere with the rear window of the chassis, and the phenomenon of abnormal locking may occur, which affects the use of the terminal user; in addition, the dummy display as a component also requires procurement, introduction of tests, and the like, which also results in an increase in cost resources.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following explains key terms appearing in the present invention.
The BMC executes a server remote Management controller, which is called Basebard Management controller in English. The method can perform operations such as firmware upgrading, machine equipment checking and the like on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller as well as RAM for data storage, flash memory and firmware for non-volatile data storage, providing basic remote manageability in terms of secure remote restart, secure re-power-up, LAN alerts and system health monitoring. In addition to the basic IPMI function and system operation monitoring function, the mBMC enables selection and protection of BIOS flash devices by storing the previous BIOS using one of 2 flash memories. For example, when the system cannot be started after the remote BIOS is upgraded, the remote administrator can switch back to the BIOS image that worked before to start the system. Once BIOS is upgraded, BIOS image can be locked to prevent virus from invading it.
The I2C bus is a simple, bi-directional two-wire synchronous serial bus developed by Philips. It requires only two wires to transfer information between devices connected to the bus. The master device is used to initiate the bus to transfer data and to generate a clock to open up the devices that are transferring, when any addressed device is considered a slave device. If the host wants to send data to the slave device, the host addresses the slave device first, then actively sends the data to the slave device, and finally the host terminates the data transmission; the master device addresses the slave device first if the master device is to receive data from the slave device. The host is responsible for generating the timing clock and terminating the data transfer.
BIOS is an abbreviation of English "Basic Input Output System", and the name of Chinese after translation is "Basic Input Output System". It is a standard firmware interface in the industry for IBM PC compatible systems. It is a set of programs solidified on a ROM chip on the internal mainboard of computer, it stores the most important basic input and output program of computer, self-checking program after starting up and system self-starting program, it can read and write the specific information set by system from CMOS. Its primary function is to provide the lowest level, most direct hardware setup and control for the computer. In addition, the BIOS provides some system parameters to the operating system. The change of system hardware is hidden by BIOS, and programs use BIOS functions rather than directly control the hardware. Modern operating systems ignore the abstraction layer provided by the BIOS and directly control the hardware components.
A Central Processing Unit (CPU) is a final execution unit for information processing and program operation, and serves as an operation and control core of a computer system.
The method aims to solve the following problems in the existing method for avoiding the limitation of a display card: false displays present an abnormal lock-on risk. The false display needs to be installed on an output interface of the display card to replace the positive display; in the installation process, due to different installation methods of operators, the false display can not be installed in place and cannot be locked normally; in addition, the false display may interfere with the rear window of the chassis, and the phenomenon of abnormal locking may occur, which affects the use of the terminal user; in addition, the dummy display as a component also requires procurement, introduction of tests, and the like, which also results in an increase in cost resources.
