Does HDMI Extension Reduce Quality? [Explained]

HDMI cables are globally used for transferring digital videos and audio signals. But the main limitation of an HDMI cable is the length it is only 3-6 feet which is too short for a Blu-ray player or a gaming console. So, the only option is to use the HDMI extension to solve this problem.

Now the question is, can you get the same quality and signal using an HDMI extension? This guide will help you learn about the HDMI extension and whether it reduces the signal and quality or not.

How Does HDMI Extension Work?

You will automatically get the answer to the question of whether an HDMI extension cable reduces the quality or not by knowing its working process.

An HDMI extension is used to extend the HDMI cable. One point of the HDMI cable plugs into the high-definition television or device and the other point plugs into the socket of the HDMI extension. The plug of the extension cable connects the HDMI cable and the Source device.

Now, the digital audio and video signals from the source device convert into an analog electric signal and go through the HDMI extension cable. As the metal pins of the HDMI cable and the extension cable are connected, the signal easily passes through it without any interruption and reaches the destination.

Does HDMI Extension Cable Impact on Quality?

So, as you already know how the HDMI extension cable works, you may have understood that the signal or quality cannot be reduced using an HDMI extension cable.

However, the question may arise in your head that the joint of the HDMI cable and the extension can be the obstacle that may reduce the quality. Well, the connector pins of the extension cable are manufactured in a way so that they never reduce the quality of a signal.

When does an HDMI Extension Reduce Signal Strength?

As HDMI cables are used on HDTVs which certainly isn’t cheap, the HDMI extensions are also made in a way so that you can get the most for your money.
