Chapter 1: What Is HDMI?
HDMI (High-Definition Multimedia Interface) refers to a high-definition multimedia interface that transmits both audio and video data through a single cable. HDMI allows for the transmission of high-quality audio and video data without the need to convert analog video signals into digital ones, preserving the quality.
HDMI was first introduced in 2003, and since then, it has undergone several updates. Each version has aimed to overcome existing limitations by improving performance and adding new features. However, there is still considerable confusion among users because each version supports different resolutions, frame rates, and color spaces.
Therefore, this article will explain the major HDMI versions and their key differences, providing guidelines on when to use each version. Finally, we will also explore what to consider when purchasing HDMI cables.

HDMI can transmit much higher quality video and audio compared to traditional analog methods. However, not all HDMI cables offer the same performance. HDMI cables provide various features and performance levels depending on the version, which may vary based on the user's requirements and compatible devices.
HDMI 1.4
HDMI 1.4, released in 2009, introduced several improvements over previous versions. One notable feature of this version is the Ethernet Channel function, which allows users to share an internet connection over a single HDMI cable.
HDMI 2.0
HDMI 2.0, released in 2013, brought significant increases in bandwidth, maximum resolution, and frame rates compared to previous versions. It also added support for various audio formats and color spaces.
HDMI 2.1
The latest version, HDMI 2.1, is most commonly used in large gaming and entertainment systems. One of the most important updates in this version is the greatly expanded bandwidth, resulting in revolutionary improvements in maximum supported resolution and frame rates, making it ideal for data-intensive applications like real-time gaming and VR (Virtual Reality).
These differences are essential considerations when choosing an HDMI cable. In the next chapter, we will delve into usage scenarios for each version.

When selecting an HDMI cable, compatibility with the devices you intend to use is crucial. Especially, factors such as supported resolution, frame rate, and required features should determine the appropriate HDMI version for your needs.
When Using HDMI 1.4
HDMI 1.4 supports Full HD (1080p) video resolution. It also allows internet connection sharing through the Ethernet Channel feature. Therefore, it is suitable for use with Full HD TVs or monitors when internet connectivity is needed simultaneously.
When Using HDMI 2.0
HDMI 2.0 supports a maximum of 4K (2160p) video resolution. This is essential for obtaining optimized picture quality on UHD TVs or monitors. Additionally, it is widely used in home theater systems due to its support for various audio formats and color spaces.
When Using HDMI 2.1
HDMI 2.1 supports resolutions up to 10K and introduces advanced features like Game Mode VRR (Variable Refresh Rate). These features are crucial for high-performance gaming computers and VR (Virtual Reality) devices, making it the recommended choice for such users.

When purchasing HDMI cables, consider the following factors:
1. Check Compatibility
First and foremost, ensure that the HDMI cable is compatible with the devices you intend to use. Some devices may only support specific HDMI versions, so be sure to check this.
2. Length and Quality
The length of the HDMI cable is also an important criterion. Too short a cable may limit installation options, while too long a cable may lead to signal loss. Additionally, cable quality matters. Cheaper cables may often cause signal loss issues, so it's best to choose products from reputable manufacturers.
3. Identify Necessary Features
Lastly, identify the features you need and select an HDMI cable version that supports those features. For example, if you need to transmit 4K video, you'll need at least an HDMI 2.0 cable. Or, if you want specific functions like internet connection sharing, choose a version that supports those features.
