HDMI 2.1: 48Gbps bandwidth
The problem with these cables is that their price is slightly higher than an HDMI 2.0 cable. Currently we can find 1 or 2 meter cables for prices that start at 13 euros, compared to 4 or 5 euros for which we can find HDMI 2.1 cables. Also, it should be added that, according to the HDMI Forum, any HDMI 2.0 connector or cable can now be called HDMI 2.1, and then list the features it supports.
Therefore, it is important to make sure that the cable supports Ultra High Speed HDMI. This refers to the fact that HDMI cables do not meet a specific standard, but can accept a certain amount of bandwidth. Cables compatible with HDMI 2.0 reach speeds of up to 18 Gbps, but to be able to send 4K signals at 120 Hz, more bandwidth is needed and therefore supports HDMI 2.1 compliant cables up to 48 Gbps. With these cables we can also enjoy functions such as VRR, ALLM and eARC.
How to Identify a real HDMI 2.1 cable
Therefore, when we buy a cable, we must verify that it is capable of using a bandwidth of up to 48 Gbps, plus it has a sticker that says “Ultra Certified Cable”. When we buy an original cable from a well-known brand, they usually carry a sticker with a QR code. We can scan this QR code with the “HDMI Cable Certification” app, available for iOS and Android.
If the cable we buy doesn’t have this sticker, that doesn’t mean it’s fake, but in that case we won’t be able to verify that it really works until we use it. Also, we always have to try to buy the shortest cable possible, as this will avoid potential signal stability issues. The higher the bandwidth, the better the cable should be so that there is no big signal degradation if we use 3 or 5 meter cables.
In summary, if you find today an HDMI 2.1 cable that measures 1 meter or more and costs less than 10 euros, you should be suspicious. On AliExpress, sellers advertise HDMI 2.1 cables alongside HDMI 2.0 cables so the lowest price range that appears is the cheapest cable, but when you go in and select the HDMI 2.1 cable, the price skyrockets. Another thing that we can do to avoid falling into fakes is to buy cables with a lot of reviews and sales, and verify that, in fact, the cable fulfills what its specifications promise.
