HDMI Version: 2.1
HDMI 2.1 is an important version of the HDMI (High-Definition Multimedia Interface) standard, which introduces a number of new features and technologies to meet the growing demand for high-definition (HD) and ultra-high definition (UHD) images.The following are the main features of HDMI 2.1:
Higher bandwidth: HDMI 2.1 provides a transmission rate of up to 48 Gbps, which can support higher resolution, higher frame rate and deeper colors than previous versions.
8K resolution support: HDMI 2.1 provides full support for 8K resolution, which allows it to handle ultra-high-definition images that are higher than 4K resolution.
120 Hz and higher refresh rates: HDMI 2.1 provides higher refresh rates, up to 120 Hz, which is crucial for applications such as games and action movies, providing smoother image performance.
Dynamic HDR: Introduces Dynamic High Dynamic Range (Dynamic HDR), which allows HDR settings to be dynamically adjusted according to each frame of the picture, providing more accurate and vivid images.
eARC (Enhanced Audio Return Channel): Improved audio return channel to support higher bit rate audio, including support for the latest audio formats and technologies, providing a higher quality audio experience.
ALLM (Auto Low Latency Mode): Introduces Auto Low Latency Mode, which allows supported monitors to automatically switch to the lowest latency setting in gaming mode, providing a more immediate gaming experience.
QMS (Quick Media Switching): This allows switching between different image sources to be completed more quickly and seamlessly, reducing waiting time.
VRR (Variable Refresh Rate): Supports variable refresh rate technology, which is beneficial for applications such as games and animations and provides smoother image performance.
In general, HDMI 2.1 improves performance in many aspects to cope with modern high-resolution, high-frame-rate and high-dynamic-range image requirements, making it one of the most advanced HDMI standards currently available.
Common HDMI interface types：
There are three main standard models of HDMI interfaces, namely Type A, Type C, and Type D.In addition, there are some HDMI interfaces for special applications.Here's a summary:
1.Type A HDMI: Also known as standard HDMI, is the most common HDMI interface, usually used to connect TVs, monitors, projectors, etc.It is a full size interface.
2.Type C HDMI: Also known as Mini HDMI,It is a smaller HDMI interface, usually used for some small devices, such as digital cameras, camcorders, etc.
3.Type D HDMI: Also known as Micro HDMI, is a smaller HDMI interface, usually used in extremely small devices, such as mobile phones, tablets, etc.
HDMI interface for special applications:
1.Automotive HDMI: HDMI interface for automotive applications with stronger connection and resistance to vehicle vibration.
In addition, HDMI 2.1 is a new HDMI standard rather than a separate interface type, which provides higher data transfer rates and supports higher resolutions and high refresh rates.This standard still uses the physical connector of Type A HDMI.
In general, there are three main standard models of HDMI interfaces, and special applications may have other variants according to needs.
After confirming the HDMI connector type, the next step is to choose the cable!
The outside of the HDMI cable is marked 'HDMI 1.3 / 1.4 / 2.0 / 2.1'These descriptions are commonly seen. The larger the number, the higher the quality and the more detailed image effects can be transmitted.These specifications are product certifications issued by professional certification agencies.
Versions and specifications: HDMI standards are constantly updated, and versions include HDMI 1.4, HDMI 2.0, HDMI 2.1, etc.Newer versions typically support higher video resolutions, higher refresh rates, and other advanced features.
Resolution and bandwidth: If your device supports 4K or 8K video, make sure your HDMI cable has enough bandwidth to support these high resolutions.Choose cables labeled High Speed HDMI or HDMI 2.0/2.1, these versions usually support higher data transfer rates.
Length: The length of the HDMI cable may affect the signal quality.
HDMI 2.0 supports 4K/60Hz, increases bandwidth to 18 Gb/s, and adds HDR technology
HDMI 2.0 enhances support for 4K.The most direct improvements include two points:
First, the bandwidth has been expanded to 18Gbps, which can support 3840×2160 resolution and 50FPS and 60FPS frames.
Second, in terms of audio, it supports up to 32 channels and a maximum sampling rate of 1536kHz.
HDMI 2.0 is an important update that greatly improves image transmission performance!Introduced support for 4K/60Hz and increased total bandwidth to 18 Gb/s.It has also been introduced to support 1080p resolution at 240 Hz and 1440p resolution at 144 Hz. For game running, it can support higher refresh rates at high image quality.
HDMI 2.0 is equipped with static HDR (high dynamic range) technology, which can achieve higher light and dark details and color contrast, making the picture look closer to the vivid and realistic colors in real life.
HDMI usually includes version, type, length, etc.Here are some common HDMI cable specifications:
1.HDMI Version: The HDMI standard is constantly updated, with each version introducing new features and improvements.Some of the major HDMI versions include 1.0, 1.1, 1.2, 1.3, 1.4, 2.0, and 2.1.New versions typically support higher resolutions, higher refresh rates, and other advanced video and audio features.
2.HDMI Type: HDMI cables are usually classified according to the functions and performance levels they support, such as standard HDMI cables, high-speed HDMI cables, high-speed HDMI cables with Ethernet, Premium High-Speed HDMI cables, Ultra High-Speed HDMI cables, etc.Different types of wires are suitable for different application scenarios and requirements.
3.HDMI Length: The length of the HDMI cable is an important consideration.Longer cables may cause signal loss, so consider the required connection distance when selecting.Generally, the recommended maximum length for standard HDMI cables is about 15 feet (4.5 meters), while the recommended maximum length for high-speed HDMI cables is slightly shorter.
4.HDMI Interface: HDMI cables have different interface types such as standard, Mini, Micro, etc. Make sure to choose the interface that is compatible with your device.
5. Supported resolutions and refresh rates: Different types of HDMI cables support different maximum resolutions and refresh rates.Especially when connecting to a high-resolution monitor, make sure the cable you choose meets your needs.
6. Other functions: Some HDMI cables have additional functions, such as supporting Ethernet channels, Audio Return Channel (ARC), etc.These features are usually available in higher-end versions of HDMI cables.
When purchasing an HDMI cable, make sure you understand the specifications required to ensure the cable will meet the needs of your device and application。
