What is the Longest 4K HDMI Cable?

If you are connecting various devices over significant distances inside your home using a 4K HDMI cable, you may want to know what could be the farthest distance it could allow without lowering the signal quality. 

Here, our audio engineers will explain the longest 4K HDMI cable can reach while maintaining high signal and resolution quality. 

How Long Can a 4K HDMI Cable Run: Length Limit for 4K

The latest HDMI cables are typically made of copper, limiting the maximum length that can obtain a strong signal. The longer the cable length, the weaker the signal can get. 

However, a 4K HDMI cable requires more bandwidth. Therefore, it is advisable to use a shorter cable length with a maximum of 3 meters only to attain the highest resolution.  

HDMI High Speed Active Cable

An HDMI cable can run for a maximum length of 25 feet (7.5 meters) without a change in signal quality. If you need to reach farther than 25 feet, you will need HDMI extenders or fiber optic connections to get a high-quality signal.

How Long Can an HDMI Cable be for 4K 60Hz?

The limitation on the cable length and resolution they can support is due to the material the cable is made of. 

For devices with 4K 60Hz resolution, the recommended length of HDMI cable is from 15 feet to 25 feet (5-7.5 meters) to perceive high resolution. 

How Can I Increase the Length of My HDMI Cable?

The length limitation of HDMI cable can be overcome using extenders, repeaters, or fiber optic connections, depending on the range you need. 

We highly recommend using HDMI repeaters for shorter ranges and fiber optic HDMI cables for medium ranges. If you need to reach longer distances, we advise HDMI extenders or fiber connection [1].

Take a closer look below to determine which one you can use to extend your HDMI cable.

HDMI Repeater

The HDMI repeater links two HDMI cables to enhance the signal and improve transmission in a shorter range. 

The maximum length depends on the HDMI cable type compatible with the device’s resolution. On average, a 4K 60Hz can be extended from 60 feet to 100 feet.  

Fiber Optic HDMI Cable

Unlike the standard HDMI cable, which is made of copper, Fiber Optic HDMI cable is made of optical fiber suitable for longer distances. The maximum length for a 4K 60Hz is 164 feet (50 meters).

HDMI Over Ethernet Extender

HDMI Over Ethernet Extender uses an Ethernet cable to extend the connection for a maximum of 130 feet for 4K 60Hz.

HDMI Over Fiber Extender

HDMI Over Fiber Extender amplifies data transmission through optical fiber cable to farther distances. It can extend the connection of 4K 60Hz from 1,000 to 3,300 feet (300-1000 meters).

Our 4K HDMI Cable Recommendations

Below are 4K HDMI Cables that surpass our signal and resolution quality expectations. We also consider the distance they can extend the connection to without resolution degradation and signal loss.

1. CableDirect 40-Ft Long 4K High Speed HDMI Cable (HDMI to HDMI Cord)

What stands out about this brand is the anti-interference shielding design that has optimum protection from signal interference. The 4K 60Hz can reach up to 13 feet. 

It uses HDMI Ethernet cable extending as far as 9.8 feet and transmits 8K at 60Hz and 4K at 120Hz. This is impressive, considering the high resolution and the length it can reach. 

Another notable feature is the gold-plated plugs which are break-proof and gives the assurance that they will last longer. They are also compatible with many devices with an HDMI port. 

2. Monoprice HDR High Speed Cable (60 Feet) in Black

We recommend this brand if you need to extend your connection further. This HDMI cable brand can transmit 4K 60Hz up to 330 feet without external converters. 

We are also impressed with its High Dynamic Range feature, which improves video resolution and noticeably richer and more vivid colors. 

Its design also elevates it from other brands. It is thinner and softer because it uses more flexible and durable polymer optic fibers than other brands that use glass fiber optic cable. 

It also comes with a lifetime warranty which will give you peace of mind and save you money from buying a replacement if it ever gets damaged. 


Do 4K HDMI cables really make a difference?

Yes, 4K HDMI cables really make a difference in terms of the maximum bandwidth capacity and speed at which they can transmit the signal. 

The cable should have the speed rate to transmit the required bandwidth for high-quality resolution. Therefore, a 4K HDMI cable impacts the color and resolution. 


It is important to determine the longest length of the 4K HDMI cable you will need when setting up your devices because it will greatly impact the quality of sound and resolution they can perceive. Hopefully, our audio team explained the essential qualities of a 4K HDMI cable for the best setup.
