Did you know there are enough HDMI cables in the world to give one to every person alive today, with around 5 billion cables still left over? This highlights the importance and versatility of these accessories in our digital, interconnected world.
HDMI technology is continually advancing, offering various types of cables.
Choosing the right one can be a challenge. If you've ever stood in a store, overwhelmed by the numerous HDMI cable options and wondered if length, thickness, color, or price matters, this article is for you. We'll address common questions about HDMI cables, helping you feel more confident in selecting the one that best meets your needs.
Full name——High-Definition Multimedia Interface
Essence——It is an interface used for transmitting uncompressed high-definition digital video and multi-channel audio data. It is widely used between televisions, computer monitors, gaming consoles, and other consumer electronic devices.
Connectors—— HDMI A/B/C/D/E 5 types. But AM(Male)/AF(female)/Mini(C )/Micro(D) are common.
HDMI cable 1.4V (Standard HDMI Cable) : Supports 1080p and 4K@30Hz,bandwidth is 10Gbps, Support Audio Return Channel (ARC).
HDMI cable 2.0V (High Speed HDMI Cable) : Supports 4K@60Hz, bandwidth is 18Gbps, support HDR.
HDMI cable 2.1V ( Premium/UltraHigh Speed HDMI Cable): Supports 4k~10k, 60Hz/120Hz/240Hz, bandwidth is 48Gbps, Support QFT & QMS, Support eARC.
Premium (with certification label) | Ultra (with certification label) |
Certified support for HDMI 2.0 with 18Gbps bandwidth, ensuring stable operation at 4K@60Hz with HDR. | Certified support for HDMI 2.1 with 48Gbps bandwidth, supporting all 2.1 features (8K, 4K@120Hz, VRR, etc.). |
A. What is it for? Watching TV shows and movies? Playing PS5/Xbox? Connecting to a computer monitor? For different devices, select HDMI cables of varying versions.
B. What devices are supported? Check the HDMI port version of your TV, game console, and graphics card.
A. For daily audio-visual needs (1080p/4K at 30Hz), a 'high-speed HDMI cable' is sufficient.
B. For 4K HDR home theaters and mainstream gaming: It is essential to choose 'Premium Certified High-Speed HDMI Cable'.
In principle, the shorter the distance, the less signal attenuation.
For digital signals, as long as the HDMI cable is qualified, the transmission of 0 and 1 data will not result in any difference in picture quality.
For the vast majority of home users, more expensive HDMI cables will not improve picture quality or sound quality. This issue depends on whether the two HDMI cables are of the same version/specification.
Of course, high-priced HDMI cables correspond to higher-level versions. If you want to watch standard 4K@60Hz video, then a high-speed HDMI cable is sufficient, and there is no need to purchase an expensive one.
Let's make an analogy: An HDMI cable is like a water pipe. A qualified pipe ensures that water reaches your home cleanly (signal is transmitted without loss). A more expensive, thicker pipe won't make the water 'cleaner,' but it guarantees that it won't burst when needing to transport a large volume of water (high bandwidth) without signal interruption. |
There is no fixed 'lifespan' for HDMI cables. The following points are 'warning signals' that indicate the need to replace the HDMI cable.
Existing Issues(reason for replacement) | Manifestation | Reasons for damage |
Intermittent signal disruption | A black screen, flickering, or snow effect has appeared. | Internal cold solder joints or bent connector damage in the cable |
Ghost images or noise | Unexplained stripes, spots, or color distortion appeared on the screen. | The shielding layer of the cable is damaged. |
Completely signal-free | After the device is connected, the screen keeps displaying 'No Signal'. | The cables have completely stopped working. |
Unable to support high resolution/refresh rate | The new equipment supports 4K at 120Hz or 8K, while the old HDMI does not support higher versions. | The existing cable bandwidth is insufficient. Need higher HDMI cables |
physical damage | Joint corrosion, bending, loosening, or the cable body being severely compressed, torn, or damaged by pets. | The cables have completely stopped working. |
A. ordinary copper wire : Signals are transmitted via electrical signals. When transmitted over long distances, the signal attenuates, necessitating the use of repeaters.
B. Transmits via optical signals, with extremely strong capabilities against attenuation and electromagnetic interference, making it highly suitable for long-distance cabling (over 15 meters). However, it is more expensive and has directionality (distinguishing between Source end and Display end, cannot be inserted incorrectly).
