HDMI Cables Explained: What You Need to Know for 4K and Beyond
Share
If you’re shopping for HDMI cables, you might be wondering which type you really need — especially with all the technical jargon floating around. Whether you're setting up a 4K streaming system, gaming rig, or just upgrading your home entertainment, understanding the differences between HDMI versions can save you time and money.
Here’s a straightforward guide to help you make the right choice.
What’s the Difference Between HDMI 2.0 and HDMI 2.1?
HDMI 2.0 cables support up to 4K resolution at 60Hz, which is great for most streaming and everyday use. But if you want to future-proof your setup or dive into next-level gaming, HDMI 2.1 is the way to go. It supports up to 8K resolution at 60Hz or 4K at 120Hz, delivering smoother motion and better performance.
Which HDMI Cable Do You Need for 4K Streaming?
For smooth 4K streaming at 60Hz, a High-Speed HDMI cable with at least HDMI 2.0 specs is sufficient. If you’re aiming for ultra-high resolutions or faster refresh rates—like 4K at 120Hz or 8K—you’ll want an Ultra High-Speed HDMI 2.1 cable.
Are All HDMI Cables the Same?
Not quite. While HDMI cables might look similar, their specifications tell a different story. The version number (like 1.4, 2.0, or 2.1) indicates how much data they can handle and what features they support. Picking the wrong cable could limit your device’s performance.
Can HDMI Cables Carry Audio?
Yes! HDMI cables carry both video and multi-channel audio signals through a single cable, making your setup cleaner and simpler.
How Long Can an HDMI Cable Be Without Losing Quality?
Generally, HDMI cables work well up to around 5 metres without any signal degradation. If you need longer cables, consider active HDMI cables or solutions like HDMI over Ethernet to keep your signal strong.

Choosing the right HDMI cable doesn’t have to be complicated. Focus on what resolution and refresh rate your devices support, then pick the cable version that matches or exceeds those specs.
