If you want to know how to check the version of an HDMI cable, here's how to do it. There are many HDMI cables out there on the market, but how do you know which one you are using?

The HDMI cable doesn’t come with its version printed on it, so you can't just look at the cable and see what version it is. Moreover, there's no noticeable physical difference between different versions, so it is impossible to tell just by looking at it.

Today, we will discuss different ways to check the version of your HDMI cable. But, before that, you might be interested in knowing whether the HDMI cable quality matters.

How to check the HDMI cable version

Different versions of HDMI support different resolutions, data rates, refresh rates, and audio formats. The most common versions are HDMI 1.4, HDMI 2.0 and HDMI 2.1.

Knowing your HDMI version will help you to make sure that your device is compatible with your HDMI cable. Here is how to tell the version of your HDMI cable.

Check out the cable

Almost all modern HDMI cables have the maximum resolution it supports labelled or printed on them. Just inspect the cable and see if 4K, 8K or 10K is printed on it. You may find it on the package as well.

If you have 4K printed on it, then it is either HDMI 1.4 or HDMI 2.0. Or if the label says 8K or 10K, then it is definitely HDMI 2.1. 

Check the specifications

The specification of your HDMI cable is usually printed on the package the cable comes in. Usually, it should mention the HDMI version here.

In case it isn't, find out the maximum supported resolution of your cable and match it with the specifications of different HDMI versions. It will reveal the HDMI version of your cable. You can use the picture below for comparison.

Check the website

If you buy the cable online, you can usually find the specifications of the cable on the website. Just find out your product and go through its specifications to find out the HDMI version.

In case the HDMI version isn't mentioned on the website, you can match the specifications as we discussed in the previous method.

How to identify an HDMI 2.0 cable

Modern HDMI 2.0 cables probably have "4K" printed or labelled on them, like this one from Capshi. You may find it on the package as well. That's one way to identify an HDMI 2.0 cable.

An alternative way is to check its specifications. HDMI 2.0 can support bandwidth up to 18 GB/s and resolutions up to 4K at 60 Hz. See if you have these numbers mentioned in the specifications.

How to identify an HDMI 2.1 cable

As we mentioned in the previous section, modern HDMI 2.1 cables have 8K or 10K printed on them or the package box. That's one way to identify an HDMI 2.1 cable, but it's not the only way.

By going through its specifications or checking out the manufacturer's website, you can identify an HDMI 2.1 cable.

With that, we are wrapping up our guide on how to check the HDMI cable version. Hope you found this guide helpful. While you are here, also learn about HDMI splitter and HDMI ARC.
