The HDMI cable that came with your device, or that old cable you've used for years, might still work, but it may not be able to unleash the full potential of new devices (such as 4K/8K TVs, game consoles, and high-end projectors). The key isn't whether the cable "can connect a signal," but whether it "can transmit all the data the device needs."

What is an HDMI Cable?
HDMI cables are the primary "bridge" for transmitting high-definition audio and video signals between modern electronic devices. Using a single cable, they can transmit uncompressed, high-quality video and audio signals losslessly from playback devices (such as computers and game consoles) to display devices (such as TVs and monitors), achieving a convenient "one-cable, all-inclusive" audio-visual experience.
Quick Reference for Main Types
The core of choosing an HDMI cable is matching it to your device specifications and desired picture quality. A cable's data transmission capacity determines whether it can support higher resolutions, smoother refresh rates, richer colors, and advanced features like HDR.

Conclusion
HDMI is the most universal and reliable digital bridge connecting the modern audio-visual world, allowing you to easily enjoy all the audio-visual feasts your devices offer.
