Comparison of the Three HDMI Cable Versions and Enabled Features

Let's have a quick look at the comparison between the three most prevalent HDMI version features. Here are some features that modern electronics utilize for audio and video transmission.

Technologies like eARC and QFT require an HDMI 2.1 cable. It provides extra bandwidth through its port and wire design. An HDMI 2.0 cable can support eARC compared to enhanced eARC by HDMI 2.1. A device can utilize the limited cable bandwidth by compromising on some other vital features. That is why you need the latest HDMI 2.1 cable to simultaneously enable all of the device's qualities. The addition of 5 wires in the HDMI 2.1 cable also makes the price tag slightly higher than the previous versions, but it's a trade-off tech heads can manage.

What Other Factors Need Consideration Besides The Core Parameters?

Besides having the core 24-pin port and wire design, we need to consider the following factors:

Material of the Link Port

Professionals and gamers who need to carry their equipment and require frequent plugging and unplugging need a solid link port material for long-lasting performance. Home users also need a high-quality link port, as stresses during cable routing can cause damage to the cable. A port comprises a casing, connector, pins, and a shell. Here is the breakdown of the material used in the manufacturing of a link port:

• ABS Plastic or Polyvinyl Chloride (PVC): These are common material choices when selecting a casing. They are light in weight and have a high impact strength. There is a slight difference in density, flexibility, chemical, and fire resistance between ABS and PVC. Generally, ABS is more rigid, while PVC is more flexible.
• Aluminum: Shell is the component that covers the casing for extra durability. A bare plastic-based port is flexible, which can cause the port's metallic internals to loosen with time. An aluminum shell can ensure the plastic does not move enough to cause the internal connector to pop out of place.
• Copper: It is the best material for pins as it is an excellent conductor of electricity in terms of price/performance. Some cables use aluminum or alloy materials as pins but are prone to wear and have lower conductivity. Choose a wire with copper pins for a firm electrical connection.
• Brass: Brass is the first choice of material for a connector. The metal gives the port Type-A, B, C, D, and E shape. It provides sufficient conductivity and toughness to hold all the internals together. Connector undergoes the most wear and tear during plugging and unplugging, so picking a more rigid material is logical.

Cable Material

A high-efficiency HDMI cable uses copper as a conductor. Copper provides the flexibility, strength, conductivity, and corrosion resistance needed for high performance. A tinned copper HDMI cable goes one step ahead by delivering extraordinary protection against corrosion. Marine applications primarily utilize them with massive exposure to humidity and moisture.

A premium-grade HDMI cable uses tinned copper wires, making them slightly more expensive than their bare copper counterparts. Here are the factors that need consideration when selecting an HDMI cable:

• Shielding: The copper wire bunch needs shielding to enhance signal resistance properties. Interference from other electronics can cause noise in the display, directly affecting user experience. The shield material can be fiberglass, nylon, PP, rubber, PVC, or aluminum foil.
• Conductivity: It is the most critical factor in wires. Always go for a cable with a copper conductor, as it has the best conductivity.
• Durability: To add durability, consider tinned copper wires as they last longer with consistent performance throughout their lives.

Material of the Cable Body Wrapping

A substandard cable can get damaged with time due to the manufacturer's choice of cable wrapping material. Frequent travelers may need to carry their wires, which can cause wear during storage, plugging, and unplugging. The cable body wrapping can include any of the following materials:

• Braided Cable Sleeves: They are the best option for cable body wrapping. It provides the flexibility, toughness, and durability that cables need. The material can be Nylon, Polyester, PET, PPS, and Nomex. Nylon is the most commonly used material and has the best performance.
• Heat Shrink: It is a tube of plastic material that shrinks when exposed to heat. Cables wrapped with heat shrinks are great for routing in small spaces.
• Spiral Wrapping: Any material in the form of a sheet wrapped around the cables is called spiral wrapped. These cables are generally pricier and have lower application in electronics.
