What Is a HDMI Socket?

The HDMI cable is an abbreviation of High Definition Multimedia Interface Cable. It can transmit uncompressed high-definition video and multi-channel audio data with high quality, and the maximum data transmission speed is 5Gbps. At the same time, there is no need to perform digital-to-analog or analog-to-digital conversion before signal transmission, which can ensure the highest quality video and audio signal transmission.

High Definition Multimedia Interface (HDMI) is a high-definition digital video and digital audio transmission capability

HDMI has the advantages of small size, high transmission rate, wide transmission bandwidth, good compatibility, and can simultaneously transmit uncompressed audio and video signals. Compared with the traditional full analog interface, HDMI not only increases the convenience of the indirect line of the device, but also provides some HDMI-specific intelligent functions, such as consumer electronics control CEC and extended display identification EDID. The HDMI cable is composed of 19 wires. The HDMI system consists of the HDMI sender and receiver. Devices that support the HDMI interface typically have one or more interfaces, and each HDMI input of the device must conform to the specifications on the transmitting end and each HDMI output must conform to the specifications on the receiving end. 4 pairs of differential transmission line groups among 19 lines of HDMI cable

usage

1. First you have to make sure your computer and TV have HDMI interface. If not, you can use DVI-HDMI adapter cable.

2. Connect the HDMI cable to the HDMI interface of the computer and TV.

3. There are two desktops in the desktop right-click properties-display.

4. Click on screen 2 and click below to expand the desktop to this screen, and your computer desktop will extend to the TV.

5. Then drag the window to the TV.

be careful

1. During the use of the HDMI cable, it is necessary to avoid excessive bending of the cable, such as frequent folding or winding, which may damage the core or shield of the line. Generally curved along the arc, it will not damage the cable.

2. Pay attention to the gold-plated brightness of the interface. The current high-quality HDMI cables on the market are all 24K gold-plated.

3. Before wiring, be sure to use the equipment to test the quality of the wire before it can be formally laid. When connecting the wires, wear a dust cap and wrap the waterproof adhesive at both ends of the cable. , So as not to cause damage, resulting in the internal capacitance and characteristic impedance structure of HDMI, resulting in signal attenuation and distortion.

4. The HDMI head is relatively fragile. It is recommended that more than two wires can be buried as a spare when it is buried, and it must be isolated from strong electric wires.
