The last thing you need is a faulty cable to cause issues with your HDMI 2.1-compatible Xbox Series X, PlayStation 5, and graphics cards from NVIDIA and AMD. These devices are pushing more pixels than ever. Here are some tips for avoiding scams.
While the HDMI Licensing Administrator is in charge of licensing the technology, the HDMI Forum is in charge of the HDMI standard. If they wish to create a product that has been licensed or approved by the HDMI Licensing Administrator, device and accessory makers must adhere to the HDMI Forum’s criteria.
Although HDMI 2.1 is the most recent specification, the organization in charge of HDMI uses a separate system to identify cables. On the packaging, check for the words “HDMI Ultra High Speed” if you wish to purchase an HDMI 2.1 cable.
In the past, HDMI 2.0b cables were supplied under the standard “High Speed” label; however, cables are not specifically advertised as “HDMI 2.1 cables.”
Look for the “Ultra Certified Cable” hologram and QR code on the box to be sure you’re buying a high-quality item. This indicates that it has undergone minimal testing and received certification from the HDMI Licensing Administrator.
In order to ensure that you receive the entire set of functions provided by HDMI 2.1, you may discover that these cables are slightly more expensive than the alternatives available on places like Amazon and AliExpress.
You may use the official HDMI Certification app for iPhone and Android to check the legitimacy of your cable when shopping for one in a store or after your online order has been delivered.
Install the app, point the camera of your smartphone towards the packaging, and then wait. A “Congratulations” message telling you that the cable has been approved should appear. According to the HDMI Licensing Administrator, the cable’s name must also be printed on its outer jacket.
A cable has not been tested if it fails the test or if a hologram or label is missing from the packaging. Although there’s not a certainty that it won’t function, there’s also no assurance that it will be able to transmit the full 48 Gbits per second allowed by the HDMI 2.1 standard.
If a cable that you thought was “certified” turns out to be unreliable, you should return it and receive a refund. Although the majority of name-brand cables, like those from Zeskit (about Php1,129) and Belkin (about Php2,249), have undergone independent testing, you should always double-check this.
It can take a lot of time and energy to troubleshoot issues with your home entertainment system, especially if a receiver or soundbar is involved. When you purchase a certified cable, at least one variable from the list of potential issues is ideally eliminated.
If the cable you’re utilizing is subpar, you can start experiencing certain specific issues. These frequently appear when attempting to utilize an older HDMI 2.0b cable with a program that is faster than the recommended 18 Gbits per second.
You might not experience any problems until you use the Xbox Series X or PlayStation 5 to play one or two 4K/120Hz games. A dark screen that accomplishes nothing, strange artifacts, and erroneous “sparkles” are just a few examples of these problems.
You can experience unexpected blackouts, flickering, or error messages stating that your TV has a “handshake” problem. This indicates that the cable isn’t capable of supporting adequate communication between the TV and the source device.
When it comes to extended distances, it might be tempting to skimp on a cable. Here is when HDMI cables start to get really pricey. The signal may deteriorate more before it reaches its destination the longer the connection is. The shortest connection you can use while still meeting bandwidth needs is the optimal cable, for this reason.
Although there is no “optimal” connection length, using an HDMI cable no longer than 10 feet is advised for 4K resolution and high frame rates (120Hz) (3 meters). The highest limit for lesser resolutions is probably between 20 (6 meters) and 50 ft (10 meters). Test a shorter cable if you’re having problems utilizing a lengthy one.
The performance of HDMI cables with fiber optics may be improved over greater distances. There were no ultra-high-speed HDMI connections using fiber optics on the market when we initially authored this article in late 2020. If at all feasible, we advised relocating your source device nearer to your TV.
Ultra-high-speed HDMI fiber optic connections, yet, are now on the market. An ultra-high-speed certified fiber optic HDMI cable, for instance, is produced by Cable Matters. It comes in a range of dimensions, including 5 meters (16.4 feet), 10 meters (32.8 feet), and 15 meters (49.2 feet.)
Every time you purchase a TV or other home entertainment equipment, many stores will try to upsell you an HDMI cable. But frequently, one will come with your gadget in the package. It is preferable to test out your setup before making any further purchases.
Despite their higher price, approved cables shouldn’t break the budget. Be aware of any wires that are outrageously costly. They provide the impression that you are receiving a product of superior quality, but you are not required to pay the extra.
Gold connections are frequently employed to create the impression that a signal is of higher quality, although they actually accomplish very little more than look showy. The majority of the cable is made of a metal other than pure gold, which is also extremely conductive.
While braided wires may last longer, HDMI cables seldom see significant wear and tear. You don’t need an extremely sturdy cable unless you’re buying one that will be constantly plugged in and out.
High Definition Multimedia Interface is what HDMI stands for. Its purpose was to move a digital signal from a source device, such as a game console, to a display or receiver. The newest version of the HDMI standard, HDMI 2.1, has undergone a number of modifications.
How much data can be sent at once is where the new HDMI 2.1 standard and the older HDMI 2.0b standard vary most. While HDMI 2.1 provides a full bandwidth of 48Gbits per second, HDMI 2.0b has a speed limit of 18Gbits per second. Accordingly, 2.1 may transmit either 4K or 8K video at 120 or 60fps.
If your HDMI 2.1 source device produces 4K/120Hz or 8K/60Hz, then you simply require an HDMI 2.1 cable. To take advantage, each device in your video chain must be HDMI 2.1 compliant.
You may still use your old TV or receiver to play games in 4K at 60 frames per second even if your source device is an HDMI 2.1 one, such as the PlayStation 5. If you intend to use the extra bandwidth, you only need it.
You won’t benefit from a faster cable for older systems like the Xbox One X, PlayStation 4 Pro, and NVIDIA’s 20 series GPUs because they can only support HDMI 2.0b. Because of this, you should avoid investing in pricey HDMI cables unless you have a good reason to.
The majority of HDMI 2.1-capable devices feature a high-speed connection that is compatible right out of the box. This includes the PlayStation 5 and the Xbox Series X, both of which are capable of outputting 4K at 120Hz. Using an aftermarket cable in place of this one won’t improve performance.
Only if you require a longer run if it is broken, or if you put your source device into a receiver and need a different cable to link the receiver to the TV, should you replace this cable.
The initial HDMI 2.1 products on the market were the Xbox Series X, PlayStation 5, and NVIDIA’s 30 Series graphics cards. Few TVs that have been on the market for a few years now have ports that support them.
However, the majority of the initial wave of 8K-capable TVs and gadgets, which are still years away from becoming widely used, was the inspiration for the new definition. In the upcoming years, a lot more HDMI 2.1 devices and accessories (including cables) will be available.
In the future, even low-cost companies like Amazon Basics will begin offering Ultra High-Speed connections with a 48Gbps capacity at low rates and without any certification.
