How to choose a HDMI cable? Differences between standards

Choosing the right HDMI cable may seem a simple matter, but in fact it is an important decision that affects the quality of image and sound, especially if we want to use the latest technologies. In this article I will discuss the differences between individual HDMI standards and tell you how to choose a cable that will best meet your needs.

What is HDMI?

HDMI (High Definition Multimedia Interface) is an interface used to send audio and video signals in high resolution. Since its inception, HDMI has become a standard in RTV equipment, computers, game consoles and other multimedia devices. The HDMI cable provides a signal transmission without losing quality, which makes it an indispensable element if you want to get an optimal image and sound.

What are the differences between HDMI standards?

HDMI has several versions, and each of them offers different possibilities, which can affect the selection of a cable depending on what type of device and functions you will use.

1. HDMI 1.4

The HDMI 1.4 standard was introduced in 2009. Supports resolutions up to 4K (4096 x 2160 px), but only at 30 Hz. This means that if you care about displaying the image in 4K at a higher refresh rate (60 Hz or more), it is worth considering choosing a newer cable.

2. HDMI 2.0

The HDMI 2.0 version, which entered the market in 2013, offers a wider range of functions and better image quality. HDMI 2.0 supports 4K resolutions at 60 Hz, as well as 32 audio channels and the ability to send a 3D signal. The HDMI 2.0 cable is therefore more suitable for modern 4K TVs and consoles that offer higher refresh rates.

3. HDMI 2.1

This is the latest standard that appeared in 2017. HDMI 2.1 offers unique possibilities - supports 8K (7680 x 4320 px) at 60 Hz and 4K at 120 Hz. In addition, it allows you to send dynamic HDR, which makes the image more detailed and realistic. HDMI 2.1 is also compatible with VRR (Variable Refresh Rate) technology, which is especially important for players. The HDMI 2.1 cable is a great choice if you have the latest equipment and you want to use its full potential.

Other factors worth considering:

1. Cable type:

HDMI cables are available in different versions - standard, high speed (High Speed) and ultra -high speed (Ultra High Speed). The higher the speed, the greater the capacity and quality of the signal sent. For 4K devices and higher resolutions, it is worth choosing a high or ultra -high speed cable.

2. Cable length:

It is worth paying attention to the length of the cable, because too long the cable can lead to the loss of signal quality. In most cases, HDMI cables up to 3 meters long will work without a problem. If you need a longer cable, consider buying an active HDMI cable that strengthens the signal at longer distances.

3. Connectors:

Depending on the devices you have, you may need a cable with various connectors. Standard HDMI, mini HDMI (e.g. in tablets or laptops) and micro HDMI (in mobile devices) differ in size, so make sure you choose the right type of cable.

Summary: How to choose a HDMI cable?

Choosing the right HDMI cable depends primarily on your needs and equipment you have. Here are some tips:

• For 4K TVs - select HDMI 2.0 or 2.1 to get high image and sound quality.
• For 8K devices - if you plan to use an 8K TV or equipment supporting this resolution, select HDMI 2.1.
• Cable length - remember not to choose too long cable, if it is not necessary to avoid deterioration of signal quality.
• Compliance with devices - check what connectors support your devices to choose a cable with the appropriate connector type.

Remember that investing in the appropriate HDMI cable can significantly affect the quality of multimedia in your home, so it's worth taking care of the right selection of the cable for your equipment.
