HDMI Data Transmission
- Jun 22, 2018 -

The longest signal transmission distance that an HDMI cable can achieve depends on the overall system: the performance of the source device, the performance of the display device, the data transmission rate of the signal, the performance and length of the cable itself. In the digital age, we use data rates to describe the amount of bit data per second. The length of the HDMI cable is closely related to the maximum data transmission rate. If there is a long distance problem, the signal received by the HDMI device will show no picture, dropped frames, snowflakes, or no sound. The shorter the HDMI line, the higher the maximum data transfer rate that can be achieved. For example, an HDMI cable has a data transmission rate of 19 Gb/s at a length of 2 m, which can satisfy 1080p, 120 Hz, and 48-bit color depth video transmission. However, if the length is 6 meters, the data transmission rate will be reduced to 10Gb/s, and it can only meet 1080p, 120Hz, 24bit color depth video transmission. So, after the length of this cable is increased, the data transmission rate will also decrease.
