If you are considering setting up, renewing your home entertainment system or installing your surround sound system you should examine your options for video and audio wires. Even though some of your gadgets may come with only one digital audio output type, the majority of modern gadgets come with both  HDMI and coaxial cable outputs. This is why you should know the difference between them. 

High-definition multimedia interface cables, commonly known as HDMI cables, and coaxial cables are both important in a home entertainment system. The image quality variations between the 2 wires have less to do with the cables on their own than the way in which the connected equipment transmits signals over those cables. But, coaxial and HDMI cables are both used with modern equipment in ways that must be considered prior to wiring.

Cables are created to interpret and deliver required signals from the programming source such as a television set, cable box. Coaxial cables used to be an important component of televisions, but modern technology has changed it by allowing the use of HDMI cables.

The final decision between an HDMI cable and a coaxial cable to use depends on the kind of signal and levels of quality ( for both; audio and video) that television cables provide.


HDMI is the preferred cable among content producers and hardware manufacturers companies. HDMI allows for 1080p video resolution combined with uncompressed audio. All of this is transmitted over a cable that is similar to a large USB cable, used with computers. The best image quality between coaxial cables and HDMI goes to the second one.

The high definition multimedia interface is a connectivity standard that has been utilized throughout the world since 2002. HDMI cables come with a simple structure composed of ten top pins and nine bottom pins. They are easily fitted, like a USB, to the HDMI port to secure a connection. They carry a digital signal.

HDMI cables are the new Digital Visual Interface cables. These wires are created to be utilized with high definition components because they are able to transmit standard and video signals.  They have connectors similar to a large USB and are found in most modern gadgets that include television sets, HD definition TVs and the latest digital equipment.

Coaxial and high-definition multimedia interface (HDMI) cables are both essential for your home entertainment system. But, HDMI cables are a higher type of cable when compared to coaxial cables.

Coaxial Cables

The coaxial cable was “born” back in the early 1900s. This type of cable was initially utilized to transmit radio and telephone signals.  A coaxial cable is built up of a copper core with 2 concentric layers separated by insulation.

Coaxial cables utilize a two-wire (signal and ground) coaxial cable connector, also known as “F” connector. This threaded termination has been employed on televisions, videocassette recorders, and gaming systems for a long time. The bandwidth of coaxial makes it perfect for transferring digital data from satellite and cable services to the decoder boxes inside the residence.

Other differences between Coaxial and HDMI cables are:

  • Coaxial cables are so much cheaper and simpler to install. They are easier to adjust than HDMI cables.
  • HDMI cables have the fastest speed for data transfer.
  • HDMI cables provide loss-less transmission for fat better video quality at higher image resolution and low brightness.
