Why are HDMI cables so Fragile?

If you didn’t already know, an HDMI cable, also known as a high-definition multimedia interface, is the most commonly used mode to transmit HD audio and video through a single line. 

HDMI cables have made enjoying our favorite content or sharing presentations a lot easier. All you have to do is plug it into your device, connect with a compatible source, and you are good to go.

However, the most common issue consumers face with HDMI cables is that they often stop working or break very easily. The question that arises is: Why are HDMI cables so fragile?

Are HDMI Cables Easy to Break?

HDMI cables typically have a thick broad wire coming out of a very tiny socket, making them quite delicate. 

Moreover, an HDMI cable normally consists of several pins connected to the sending and receiving devices. As these pins are tiny, they can easily break, bend or get twisted. 

Therefore, if you push the cable in too hard or put too much pressure on the line while it is plugged in the device, there is a high chance you could end up damaging the port. 

There are several premium options available for HDMI cables. It all comes down to the quality it transmits. The build is pretty much the same in most HDMI cables, making them all susceptible to damage. 

The answer is simple, HDMI cables can break easily.

As mentioned above, HDMI cables are made of multiple tiny pins, 19 to be precise. These 19 pins are usually found in three different sizes and are susceptible to damage. 

While the cable itself seems pretty tough due to the thick external layer – in reality, it is quite fragile. The HDMI cable has no proper lock mechanism, and nothing protects the cable coming out from the tiny socket. 

Therefore, any mishandling, even a slightly pressured tug, could easily damage the port and cause the HDMI cable to stop working. 

HDMI cables are the most susceptible to breakage/damage when bent or pulled in unusual directions. 

When the cable is stretched out far too much or left hanging in weird positions, it puts pressure on the wire and its pins, causing them to either bend or break. 

This is damaging for both the cable and the device it is connected to. 

Are HDMI Ports Delicate?

The simple answer to this is yes, HDMI ports are extremely delicate. While they are durable and portable, these ports still need to be dealt with carefully. 

When plugging in your cable to the port, make sure to do so delicately with as minimal pressure as possible. If you try to force it in, the cable might end up damaging the port. 

Sometimes, HDMI pins tend to break while connected to a port and get stuck between the gaps. In this case, you have to replace the entire port instead of just the cable. 

Furthermore, if you use your HDMI cable and port for heavy transmissions regularly, it can cause wear and tear. Heavy usage over a longer course of time can mess with your connection.

Not only do they break, but HDMI ports are also affected by power surges. When the electricity is constantly fluctuating, it can damage your electronic items and accessories. HDMI ports are very sensitive to such issues. 

How Do I Protect My HDMI Cable?

There are many ways that you can try and prevent your HDMI cable and port from being damaged. Let’s take a look at a few options: 

HDMI Power Surge Protector

These HDMI Power Surge Protectors work in a way that helps prevent any rapid fluctuation in electricity from passing through your cable. This way, your HDMI port stays protected.

However, as we have already covered, HDMI ports and cables are very fragile, and any interference with them could cause them to stop functioning. 

Since surge protectors are made to control any dramatic shifts in the voltage, they also add a small electric charge to the source they are connected to. 

Normally this goes unnoticeable, but if you directly connect the surge protector to your HDMI port, the electric charge could cause issues with the displayed image. In addition, it could also result in the complete malfunctioning of the port. 

Before installing surge protectors directly to your HDMI port, one thing you should consider is that any voltage shifts will not be directed from the port. 

If you were to experience a power surge, it would most likely come from the main power source and affect all your electronic devices. Ideally, the surge protector should be installed on your main power source.

Even though HDMI cables do not have an expiration date, at some point in time, you will eventually need to replace your cable with a new one. 

If you are experiencing problems beyond repair, then it is time to invest in a new cable. 

When looking for a new cable, we would suggest you look for stronger HDMI cable structures. There are many options available with protected layering, which guarantees minimal damage to your HDMI. 

However, regardless of how strong the cable itself is, you should handle HDMI cables very carefully, and any rough treatment could harm them no matter how sturdy the structure is. 

Moreover, with new updated versions for HDMI, there is also a high chance that some may eventually stop working because they are no longer compatible with your device. 

It is better to upgrade your HDMI cable to avoid inconvenience. 

The Bottom Line

If your cable has reached its end and are looking to invest in a new HDMI cable or are wondering why yours went bad – we hope this article helped you learn about the sensitivities of an HDMI cable and port. 

The next time you are using an HDMI cable, remember to be extra careful with how you handle it.
