The utility model discloses an amplification connecting line for a high-definition multimedia interface (HDMI) line. The amplification connecting line comprises an amplifier connected to an input end of an HDMI connecting line and an output plug at an output end of the HDMI connection line. The amplifier comprises a housing, a signal amplification chip and a circuit board. The signal amplification chip is arranged on a bottom surface in the housing, and a top end of the signal amplification chip is provided with the circuit board. An output end of the amplifier is provided with an input jack. The beneficial effects are that the output end of the large-length HDMI line for transmitting high-definition video and audio signals is inserted in the input jack of the amplifier; the amplifier is used for increasing high frequencies; and zero compensation signal attenuation can be generated after long-distance transmission to increase high frequency gain, and then the signals are sent to output equipment such as a display, a projection, a high-definition television through the output plug.
