How to Tell HDMI Cable Version: What Actually Matters

The version should be clearly labeled on the packaging . Check the cable: Look at the cable itself for any labeling or text that may indicate the version. The HDMI version number may be printed on the cable, or it may have a different color to indicate the version.

When it comes to HDMI cables, there is a lot of debate around whether or not it is worth spending extra money on something fancy. However, it is important to consider the correct materials used inside an HDMI cable, as it can make a big difference. In this article, we will discuss what actually matters when buying an HDMI cable.

Firstly, it is important to avoid cheaply made HDMI cables that sometimes use steel, which is not a good conductor. Instead, go for cables with pure copper wiring inside. Copper cables are not super expensive, and you do not need to get anything higher grade, such as silver-plated copper.

The thickness of the wiring inside the cable is measured by something called a gauge number. A lower number means a thicker wire. Your cable length should not exceed 1.5 meters with a thin 32 gauge wire. However, as you go thicker and thicker, you can safely have a longer and longer cable run without having to worry about signal attenuation or interference.

Another thing to consider is the connectors on the end of the cable. Gold plating is better as it will give you better longevity, as the gold is an effective barrier against wear and corrosion.

Once you have found a cable made with good materials, try and find out if it has been tested to work with a wide variety of equipment. Some cheaper cables are only tested with a couple of monitors, so they might not play nicely with your gadgets if you are running them in any kind of setup that is not super-straightforward, such as with an HDMI splitter.

Make sure you are buying a Premium High-Speed cable if you want 4k at 60 hertz or HDR. These have a speed of around 18 gigabits per second, as opposed to the 10 gigabits of the more standard high-speed cable.

In conclusion, generally speaking, shorter and thicker is better when it comes to HDMI cables. If you are looking to get the most out of HDMI 2.1, you probably do not want to get a cable longer than three meters.


How can I check my HDMI version?
To find the version of an HDMI port or cable, consult the device specifications from the Original Equipment Manufacturer. Different HDMI versions have been developed over the years, each version determining the capabilities and supported features of a configuration (limited by the lowest version port or cable).
How do I know if I have a HDMI 2.0 cable?
The only difference between all HDMI versions lies in their capabilities. However, you can look out for a UHD or 4K logo on the cable connectors or packing to find out if you are interacting with an HDMI 2.0 cable.
How can you tell the difference between HDMI 2.1 and 2?
HDMI 2.0 vs 2.1 – Features HDMI 2.0 has a bandwidth capacity of 18 Gbps (gigabits per second). HDMI 2.1 takes the number up to 48 Gbps, which means that HDMI 2.1 does not have to compress that much of the data and preserve a better data quality during the transmission process.
How do I know if my HDMI cable is 4K?
Purchase from a well known manufacturer and read the specs on the cable plastic protection cover. Any HDMI cable labeled high-speed (18 Gbps) transfer speed is 4K compatible.
