Although some manufacturers have worked hard to label cables as "HDMI 2.0" or "HDMI 2.1", the difference between one HDMI cable and another HDMI cable is not the HDMI version. The version number (1, 1.4, 2.0, etc.) describes the function of the hardware (TV, soundbar, A/V receiver, etc.), not the HDMI cable.
In other words, there is a correlation between the HDMI version your device uses and the type of HDMI cable you should buy.
When choosing an HDMI cable, speed is the biggest consideration, because if the cable is not fast enough for a particular device, HDMI version, and media source, it will be unreliable.
HDMI cable speeds are measured in gigabits per second (Gbps); don’t worry, you don’t need to remember many numbers. For simplicity, HDMI.org (an organization that maintains specifications for HDMI devices and HDMI cables) has categorized
Divided into four main categories:
If you don’t have a 4K TV and don’t plan to buy it soon, a standard HDMI cable may be what you need: it supports high-definition video in 720p and 1080i resolutions. We have seen that 1080p can be used with standard HDMI cables, but this is not guaranteed. You can use these cables for DVD players, Blu-ray players, game consoles, streaming media players, and even A/V receivers and sound bars. Remember, if you decide to venture beyond the realm of HD, you may need a faster solution.
This is the main force in the A/V world. The high-speed HDMI cable can manage any device or content, up to 4K video at 30Hz. Supports all 3D videos, dark colors, and of course 1080p HD. Static HDR (such as HDR10) can also be used, although if you want to experience Dolby Vision HDR, we do not recommend using this cable. As a dynamic version of HDR, it uses a lot of data and therefore benefits from faster cables.
As long as you stick to the world of 4K, and you don't want to use cutting-edge features like 8K or eARC, an advanced high-speed HDMI cable will keep you using it for a long time. Guaranteed to provide 18 Gbps, which is necessary for HDMI 2.0b devices to perform optimally. The cable can support 4K up to 60Hz, all HDR versions including Dolby Vision and HDR10+, and an audio relay channel (ARC), so you only need to connect once to simplify the cable connection to the TV.
If you have bought a TV or any other A/V equipment in the past two or three years, then high-speed high-speed is the best choice.
Welcome to the top of the HDMI Tower.
Suitable for those who want the ultimate proof of the future. On behalf of the forefront of HDMI technology, it is guaranteed that the ultra-certified cable can provide a complete 48 Gbps rate, which can realize all the advanced functions in the HDMI 2.1 specification, including 8K video, eARC and multiple variable refresh rate (VRR) technologies .
Do you need this kind of cable? We will not say it for the time being. The only way to truly utilize its extra bandwidth is through the use of HDR's local 8K signal source, which is currently difficult to achieve.
Ideally, you should choose the HDMI cable with the shortest length to place the required components. However, the setting habits are changed when you add, remove and relocate audio-visual equipment, so please make sure to choose a HDMI cable that is long enough to meet your current and potential future needs, especially if you install it on a wall Or the ceiling.
But please be aware of any HDMI cables longer than 25 feet. These extra-long cables may suffer from signal attenuation, and you may find that long cables cannot maintain a reliable connection between devices. Before permanent installation, be sure to check to make sure that the HDMI cable is suitable for all devices and content types. Active HDMI cables use a smaller chip to borrow a small amount of power from the device connected to it, thereby helping to maintain signal strength over longer distances.
When considering the use of longer cables, cable quality becomes more important. Before buying a long cable, please read customer and professional reviews carefully and make sure that the manufacturer has a good warranty.
If you plan to pass the HDMI cable through a wall or ceiling, you must evaluate it for that type of use. Do not use a standard HDMI cable behind the gypsum board; its protective cover has not been designed to withstand accidental contact with construction materials such as nails, screws, and metal drywall. Look for cables with CL2 or CL3 ratings and always check local building codes for compliance before installation. Even if the HDMI cable is rated for use in the wall, connecting the cable to the wall is not always a good idea. Please check the "HDMI Alternative Products" section below to learn about other ways to transmit A/V signals through walls or long distances.
What is the difference between certified and uncertified HDMI cables? not much. If the HDMI cable is indeed a high-speed cable, it will perform all the required work, such as transmitting 4K/60Hz, high dynamic range (HDR) and 4:4:4 dark video and uncompressed audio.
The difference is that
The cable has been independently tested and meets HDMI.org's "Ultra High Reliability" standard. We think the HDMI cable will work or not, but for some people, the extra peace of mind that comes with the reliability certification is worth a few dollars more. The size ranges from 3 to 30 feet, and the starting price is less than $10.
It is the cheapest certified cable we can find, and like all Monoprice cables, it has a lifetime warranty.
All high-speed HDMI cables can easily support 4K video, as the name suggests, this is one of the cheapest but most reliable ways to connect HDMI devices. These cables range in size from 3 to 100 feet, start at less than $10, and come with Amazon's lifetime warranty.
The weird thing is
The price is usually the same as the price of a high-quality high-speed HDMI cable certified by Monoprice, so which price you choose may only be based on shipping and other considerations-Amazon Prime members can use this cable for free, while Monoprice.com charges a small shipping fee.
Remember when we said that there is no HDMI cable with ultra-high speed certification? Yes, but there are still uncertified cables claiming to meet the same specifications. Cables such as
, Its data rate is 48Gbps, which is enough for 8K at 60Hz or 4K at 120Hz.
Despite these excellent features, these cables are still cheaper than movie tickets and can be used for life.
Wondering why we don't just put
At the top of the list? Well, it has one major drawback: it's very short. Currently, Monoprice only offers lengths of up to 8 feet. This will not leave much leeway for your future 8K home theater settings.
In the past, most experts would say that HDMI cables are valid or invalid. Oops, we said earlier in this article. Unlike an analog cable, in an analog cable, the signal quality will change from good to bad, and will have a corresponding impact on video or audio. HDMI is a digital cable, and zero and zero have no quality. They either make it from the source device (such as a Blu-ray player) to the target device (TV), or they don't. Sometimes, if there is a problem with the signal path (usually due to too long cable runs), "sparks" will appear on the TV screen. This means that certain "1"s and "0"s have not crossed the gap. The solution is almost always to replace your HDMI cable with a shorter cable.
However, new technologies such as Dolby Vision and HDR10+ use much more bandwidth than HDR10. These formats are usually called dynamic HDR, and the transmission speed of HDMI cables can be very picky. For example, when you enable Dolby Vision on Apple TV 4K for the first time, it will test the speed of the HDMI connection with a Dolby Vision compatible 4K HDR TV. If the speed is not fast enough, you will not be able to use Dolby Vision, and Apple TV will revert to HDR10 HDR content. We found that even with a high-speed cable that passed this speed test, the Dolby Vision connection sometimes dropped, resulting in a black screen.
Therefore, we strongly recommend that if you have a Dolby Vision or HDR10+ A/V device, you only purchase a high-speed HDMI cable that is guaranteed to provide a full rate of 18Gbps, and it will be more permanent before full testing with Dolby Vision or HDR10+ content Install them.
As long as the HDMI cable is CL grade, it is usually no problem to pass the HDMI cable through the wall within a distance of 10 feet or less. However, this setup is not ideal even with cables for use in walls. On the one hand, if damaged, they are difficult or impossible to repair, which makes them a problematic option for use in walls, according to Jeff Napoleone,
In Toronto. If you insist on using HDMI, Napoleon recommends installing cable ducts behind the wall. This makes the laying of cables easier and provides additional protection.
One
May be a better solution, especially at longer distances. System use
, It is easier to penetrate the wall and repair than a damaged HDMI cable.
Compared to HDMI, a network cable may be a more cost-effective choice, especially if you want to span long distances. Costing a few pennies per foot usually saves money in the long run, even though the required transmitter and receiver may cost more upfront. Another benefit is that as technology advances, the transmitter and receiver can be replaced with newer devices without the need for rewiring.
