HDMI which stands for High Definition Multimedia Interface is an audio/video interface that can be used to interconnect various multimedia devices. One of the common use for HDMI is when a CPU is connected to a monitor and a projector. Aside from that, it can also be used in connecting Blu-ray players and laptops to televisions as well as monitors.
One of the main advantages of using HDMI is that it can transmit both audio and video at high qualities such as 4K using only a single connection. However, you may also experience some issues in using it every now and then and one of them is when you find that after connecting the devices using the HDMI port, the screen appears to be black and there is no audio output. In such cases, there are a variety of hardware malfunctions that could be causing the problem with the HDMI connectivity.
