There are two connectors behind the monitor. What interfaces are they?

1, both video interfaces. The white one is called Dvi, and the blue one is called Vga, which can transmit video signals by cable.

2.DVI interface DVI interface is a digital interface, which can encode pixel data and transmit it through serial port. The digital signal generated by the graphics card is encoded by the transmitter according to the TMDS protocol, and then sent to the receiver through the TMDS channel, and then decoded and sent to the digital display equipment.

3. There are two sockets for inserting the monitor behind the computer host, namely DVi socket and VGA socket. DVI is a digital high-definition interface, which can transmit high-definition video signals and audio signals. VGA is a traditional video signal output interface, which is used to connect the display and cannot output audio signals.

4. The interface behind the computer monitor is generally the power supply and vga interface.

5, DVI-D interface, DVI is a high-definition interface, but there is no audio, that is to say, DVI video wiring only transmits picture graphics signals, not audio signals. Now some monitors that support 4K resolution also have DVI interfaces.
