HDMI cable is a high-definition multimedia interface cable, which can transmit uncompressed video and multi-channel audio data with and the maximum data transmission speed is 5Gbps. At the same time, there is no need for digital/analog or analog/digital conversion before signal transmission, which can ensure the video and audio signal transmission.

The HDMI cable supports a data transfer rate of 5Gbps, which is enough to handle a 1080p video and an 8-channel audio signal. And because a 1080p video and an 8-channel audio signal requires less than 4GB/s, the HDMI cable has a lot of headroom. This allows it to connect the DVD player, receiver and PRR separately with a single cable. In addition, HDMI supports EDID, DDC2B, so the device with HDMI has the characteristics of "plug and play", and "negotiation" will be automatically performed between the signal source and the display device to automatically select the most suitable video/audio format.

HDMI has the advantages of small size, high transmission rate, wide transmission bandwidth, good compatibility, and can transmit uncompressed audio and video signals at the same time. Compared with the traditional all-analog interface, HDMI not only increases the convenience of wiring between devices, but also provides some intelligent functions unique to HDMI, such as consumer electronics control CEC and extended display identification EDID.

Usage 1. First of all, you have to make sure that your computer and TV have HDMI ports. If not, you can use a DVI-HDMI adapter. 2. Connect the HDMI cable to the HDMI port of the computer and the TV. 3. There will be two desktops in the desktop right-click Properties - Display. 4. Click on screen 2, and then click on the bottom to extend the desktop to this screen, your computer desktop will be extended to the TV. 5. Then drag the window to the TV.

Be careful During the use of the HDMI cable, it is necessary to avoid excessive bending of the cable, such as frequent folding and winding, which may damage the core or shielding layer of the line. Generally curved along the arc, will not damage the cable. Pay attention to the gold-plated brightness of the interface. Now the better quality HDMI cables on the market are 24K gold-plated, which can effectively solve the problem of poor contact after the plug is inserted and pulled for many times, so as to avoid the phenomenon of signal loss and affect the picture effect. Before wiring, be sure to use the equipment to test the quality of the wire material before it can be formally laid. When paying off the wire, wear a dust cap on both ends of the connector and wrap it with waterproof glue. Try to open the groove and pay off the wire. , so as not to cause damage, resulting in the internal capacitance and characteristic impedance structure of HDMI, resulting in signal attenuation and distortion. The HDMI head is relatively fragile. It is recommended to bury more than two wires as a backup when burying the wire. It must be isolated from the strong electric wire.
