Industrial operation displays need to support a variety of input interfaces to meet the input requirements in different application scenarios. The following are several common input interfaces:

1. VGA: The VGA interface is an interface for transmitting analog signals, which is suitable for some old-fashioned devices. It is a relatively common interface type that can be used to connect computers, monitors, projectors and other devices.

2. HDMI: The HDMI interface is an interface for transmitting digital signals, which can support high-definition video and multi-channel audio transmission. The HDMI interface is widely used to connect high-definition devices such as high-definition TVs, movie players, and game consoles.

3. DVI: DVI interface is a digital video signal interface that can transmit high-definition video signals. The DVI interface has been gradually replaced, but some old industrial equipment may still need to use it.

4. DisplayPort: DisplayPort is a digital video interface standard that supports high resolution, high frame rate, and multi-screen interference interfaces.

5. USB: The USB interface can not only be used to connect peripherals such as mouse and keyboard, but also can be connected to other devices for data transmission. For example, it can be used to connect cameras, mobile hard drives, etc.

For industrial operation displays, it needs to support different input interfaces in order to meet the needs of different fields such as mechanical control and automation. Therefore, the industrial operation display needs to support a variety of input interfaces, and needs to support multi-screen synchronous display function to meet the user's multi-screen operation needs.

Multi-screen synchronous display refers to synchronously displaying the images displayed on multiple screens on one screen, which can greatly improve operation efficiency and work efficiency. The industrial operation display needs to support multi-screen synchronous display function, which allows users to view the operation interface on multiple screens at the same time, easily complete complex operation processes, and greatly improve work efficiency.

In short, industrial operation displays need to support multiple input interfaces and multi-screen synchronous display functions to meet the different needs of users and improve work efficiency.
