What Is the Difference Between HDMI Input and Output?

As mentioned in the introduction, HDMI is a cable with technology to help enhance the visual-audio output signal or transmission between the display and receiver. This article aims to help distinguish the differences and share important information behind the operation mechanism.

However, to help you grasp a clear-cut difference between the HDMI input and Output, we must consider two things as the HMID is concerned. first is the purpose, and secondly, the use of HDMI cable

1. Purpose of HDMI Input and Output

Regarding the purpose of the HDMI input and Output will expose you to the needed differences between these cables. The HDMI input functions by connecting one end of the cable to a port labeled 'HDMI IN' and the other to a source device like an AV or Blu-ray player. This setup transmits data from the source to the HDMI input. 'Input,' indicated by 'In,' means the device receives the sound or video.

Conversely, HDMI output involves transmitting audio and video data from the source. One end of the cable is connected to a port marked 'HDMI OUT,' and the other end to a TV, monitor, or other display device's 'HDMI IN' terminal. The HDMI output sends data out from the source to the input port of the display device.

2. Usage of the HDMI input and Output

We have covered the purpose of each cord in the above section, and to make it more clear, we also need to delve into the basic usage of HDMI. Laptops will never feature the HDMI input port. Therefore, all the HDMI ports on the laptop are collectively Output.

In the case of surround sound receivers, monitors, and televisions, these display devices feature multiple HDMI inputs rather than outputs. HDMI Output is designed to send out the data found on laptops, Blue Ray players, gaming consoles, etc.; anything meant to help display something must have the HDMI Output port. But television is the only device with HDMI input as well as output ports.

Facts about HDMI Input and Output

Comparison of HDMI Input and Output in practice This approach will also give us an excellent perspective on the differences between the HDMI input and output cord. This section will cover some of the few use cases on the display devices we encounter daily. The first one is the laptop PC.

On most laptops, you will always find the HDMI outputs on the ports. We have never encountered a laptop featuring the HDMI input, and maybe in the future. This is because laptops are not meant to receive video and audio signals from outside besides their motherboard. Because in your routine, you're utilizing the desktop computer, then you are using the HDMI input port as long as you are utilizing the HDMI port as the ideal video capture card.

But the only exception is when the HDMI port is on the motherboard or along the graphics cards. In such a case, you are utilizing the HDMI Output. Today, most TVs come with 3 HDMI ports. Among these, two are designed for multi-use cases. These three are HDMI(Only), which is meant to input only the HDMI signal; HDMI (DVI) you can use to input the DVI and HDMI converted signal, then HDMI(ARC).

This is the only HDMI input that features double the Output. Therefore, the digital TV comes with HDMI input and output ports. Hence, you can use the ARV to output the audio signal to the surround sound system. When it comes to the monitors, which are typically the input devices, monitors have HDMI input ports to display the Video. There are also monitors with built-in speakers, which means they accept Video as well as audio signals.

Pros and Cons of HDMI

In this section, we will share a few highlights of the pros and cons of HDMI cords to give you a better view and deeper understanding.



If you are still stranded and want to test the port on your device to gauge if it is input or Output, then the easiest way to test is to connect the device to the TV and gauge the way it functions: input or Output. Also, note that computers do not have HDMI input for some reason. HDMI manages multiple issues. Among them is HDCP protection, which can quickly slow down the regular operation of your computer.

Making an HDMI connection is vital, but most importantly, you must first understand your device's HDMI input and output ports. This will give you the most effortless approach to troubleshooting the issues properly. HDMI cables feature 9 pins at the end of either side. These ends can be used as input and output percentages; there are no female and male terminals.


So far, we have explored HDMI in detail and presume you now understand the differences between HDMI input and Output under different circumstances. HDMI receives the data signal, while HDMI output sends the data signal. Though some devices are incompatible with the HDMI input, most work well to transmit high-quality audio-visual. Read the above article and understand the HDMI science technology.
