How To Tell If HDMI Cable Is 4k: Know in Details

High-speed HDMI cables are used to carry a 4k video signal. HDMI stands for “High Definition Multimedia Interface.” It is a standard and a port for transmitting high definition digital video/audio data between devices. It has many different uses. We can enjoy videos at a 60 fps frame rate through this cable, which is very smooth and astonishing.  

This cable is mainly a media between video sources and TV or A/V receivers. In this article, we will discuss how to tell if the HDMI cable is 4K and which cable will be suitable for better(4k) picture quality? So, let’s elaborate on some issues.

Does Every HDMI Cable Support 4K Ultra HD?

Not at all. In 2002 HDMI cable version 1.0 was invented, which does not support 4k Ultra HD. After that, version 1.3 was invented, which can deliver 4K videos depending on the cable quality. Version 1.4 is 4k supported but not guaranteed. In 2013 version 2.0 was released, known for high-speed HDMI cable-supported 4k ultra HD with a guarantee.

So, it is necessary to know which cable you should use for your TV before switching to a 4k ultra HD supported TV. Nowadays, most cable supports 4k.

How To Tell If HDMI Cable Is 4k?

Some earlier cables can’t transmit HDR (High Dynamic Range) data. So, you have to be careful about that. If you use that backdated cable, then 4k content won’t be passed on your TV screen or A/V receiver. So, it is very important to know how to tell if the HDMI cable is 4k.

There are some issues you should know about 4k supported cables before purchase. There are two types of cables; one is ethernet cables, and another is non-ethernet cables.

High-speed HDMI cables also come in ethernet and non-ethernet versions. The first 4k supported categorized cable was invented in 2009, which was version 1.4. This version added ethernet activity, audio return channel, and 3D capabilities. Version 2.0 is the latest version of this cable.

The main difference from version 1.4 is its bandwidth and capability to present a wider variety of colors. This version qualified to have a bandwidth of 18 Gigabits per second, delivering 4k resolution at 60 fps (Frames Per Second).

Most of the 4k videos run at 24 to 30 fps but nowadays, 60 fps frame rate is very popular. Even YouTube started hosting 4k videos at 60 fps frame rate. 60 fps is usually used by a gamer who is playing video games in 4k resolution.

Most of the cables purchased after 2009 are 4k supported, but there are some quality issues. Some organizations produce a low-quality product to sell at a high price, like standard 4k supported cables.

You should not have any confusion about if HDMI cables support 4k or not. Because every 4k supported cable is labeled with the “HDMI High Speed” logo. Sometimes the cable itself does not carry this logo. If you want to be 100% sure, you have to purchase a new cable with explicit HDMI High-Speed support.

When To Reuse An HDMI Cable You Already Own?

If you already own a cable, the first step you should do is check if it is labeled “High Speed,” “Premium High Speed,” or “Ultra High Speed” or not. If you couldn’t find any label or logo on the cord, you should find any kind of manufacturer number which can tell you if it is 4k supported or not. If that doesn’t work, there is another method—plug in your cable into the TV or A/V receiver.

If you get stable video quality without any interruption, then you are good to go with your existing cable. But I recommend you to go with the first method; plugin and checking would be a disturbance depending on your device.

When To Buy A New HDMI Cable For Your 4K TV?

If you have purchased a new 4k HDR supported tv and don’t have an HDMI cable, you need to buy a new one. To buy a new cable, you should be careful about low-quality cables. Some cable manufacturers provide fake/low-quality cables to make more profit, which will not deliver good video quality. So, to buy a new HDMI cable for your 4k TV, a trusted shop would be recommended.
