HDMI 1.4, HDMI 2.0, and HDMI 2.1 are different versions of HDMI (High-Definition Multimedia Interface) that vary in terms of specifications, capabilities, and use cases.

1. HDMI 2.1 is the latest version of HDMI, featuring 48Gbps bandwidth for transmitting 8K video and audio signals. HDMI 2.1 is now implemented in gaming consoles such as Xbox Series X and PS5, as well as some high-end AVRs and TVs. Additionally, to take advantage of HDMI 2.1 capabilities, you need cables, signal sources, and displays that all support the HDMI 2.1 standard.
2. HDMI 2.0 cables are currently the most widely used, employed in devices like the PS4 Pro and most 4K TVs. HDMI 2.0 supports 4K Ultra HD and is the most common connection type in broadcast studios, corporate meeting rooms, digital signage, control rooms, and classrooms.
3. HDMI 1.4, released in 2009, is an older interface standard that you'll find in previous-generation gaming consoles and technology, such as the Xbox One, PS4, and HD TVs. It supports 4K video and can meet basic audiovisual and gaming signal transmission needs.

Here are the detailed specifications differences:

Which HDMI cable should you wholesale or purchase? We're here to provide you with the best recommendations.

• If you're after faster transmission speeds and the ultimate entertainment experience, creating an immersive gaming room or home theater, HDMI 2.1 is the best choice. It is backward compatible with HDMI 2.0 and can also meet future 8K and 10K requirements.
• If you need a cable for connecting standard devices and displays, like in an office or at home, we recommend purchasing an HDMI 2.0 cable. It is cost-effective and provides the basic functionality to meet your needs.
• If you want to connect devices with HDMI 1.4 ports, then an HDMI 1.4 cable is the best choice. It is affordable and will not require you to spend extra money on additional features.

Fiber Active Optic HDMI (AOC) cables are primarily designed for longer cable distances. When you need to buy a HDMI cable over 16 feet (5 meters), we recommend opting for a fiber optic cable.

Fiber optic cables are active cables containing signal amplifiers to ensure video and audio transmission over long distances without signal loss. Since they only work in one direction, you must connect the source to the source end and the destination to the display end. They are lighter and thinner than copper cables. However, it is worth noting that although fiber optic cables are highly durable, they are more fragile than copper cables.

Copper passive HDMI cables are standard HDMI cables that lack active signal enhancement and are reversible. Passive HDMI cables are less expensive than active cables, and most cables purchased for home use are passive cables. Active cables are primarily used in engineering industries, such as pipeline or wiring.
