HDMI Cable Types
HDMI cables are sold by bandwidth category, not by version number. From slowest to fastest: Standard (1080i), High Speed (1080p / 4K @ 30 Hz, 10.2 Gbps), Premium High Speed (4K @ 60 Hz HDR, 18 Gbps), and Ultra High Speed (4K @ 120 Hz and 8K, 48 Gbps). There is officially no such thing as an “HDMI 2.1 cable” — the correct name is Ultra High Speed. Pick the category that covers your resolution and refresh rate; a more expensive cable will not improve the picture beyond that.
A common myth is that HDMI cables come in versions like 1.4, 2.0, or 2.1. They do not. Devices have HDMI versions; the cable's only job is to carry enough bandwidth. The HDMI organization defines a small set of named cable categories, each certified to a maximum data rate. Match the category to what you want to display and you are done.
HDMI cable categories compared
| Cable category | Max bandwidth | Handles up to | Certification |
|---|---|---|---|
| Standard | ~4.95 Gbps | 1080i / 720p | — |
| High Speed | 10.2 Gbps | 1080p, 4K @ 30 Hz, 3D | Optional |
| Premium High Speed | 18 Gbps | 4K @ 60 Hz with HDR | Premium HDMI Cable Certification |
| Ultra High Speed | 48 Gbps | 4K @ 120 Hz, 8K @ 60 Hz, VRR, eARC | Ultra High Speed HDMI Certification |
Each category also comes in a “with Ethernet” variant that adds the HDMI Ethernet Channel (HEC); it is otherwise identical, and HEC is rarely used in practice. Automotive HDMI is a separate ruggedised category.
Which HDMI cable do I need?
- 1080p TV or monitor: any High Speed cable is plenty.
- 4K @ 60 Hz with HDR (most 4K TVs, streaming, current consoles in HDR): Premium High Speed (18 Gbps).
- 4K @ 120 Hz, 8K, or full HDMI 2.1 gaming (PS5/Xbox Series X at 120 Hz, 8K TVs): Ultra High Speed (48 Gbps).
- Long runs (over ~5 m at 4K): use an Active or Active Optical (AOC) HDMI cable.
Does a more expensive HDMI cable give a better picture?
No. HDMI is digital: within a cable's bandwidth limit the image arrives intact, or it fails visibly (sparkles, dropouts, or no signal). There is no “richer color” or “deeper black” from a pricier cable. What you are paying for at the high end is enough certified bandwidth and reliable build quality — not image quality.

HDMI cable types: frequently asked questions
Do HDMI cables have versions like 1.4, 2.0, or 2.1?
No. HDMI cables are rated by bandwidth category — Standard, High Speed, Premium High Speed, and Ultra High Speed — not by version numbers. Devices have HDMI versions; the cable only needs enough bandwidth to carry the signal. Calling a cable an “HDMI 2.1 cable” is unofficial; the correct term is Ultra High Speed.
What HDMI cable do I need for 4K?
For 4K at 60 Hz with HDR, use a Premium High Speed HDMI cable (18 Gbps). For 4K at 120 Hz, use an Ultra High Speed HDMI cable (48 Gbps). A basic High Speed cable only reaches 4K at 30 Hz.
What HDMI cable do I need for 8K, 120 Hz, or HDMI 2.1 features?
Use an Ultra High Speed HDMI cable. It is certified for 48 Gbps and supports the full set of HDMI 2.1 features: 8K at 60 Hz, 4K at 120 Hz, VRR, and eARC.
Is there really a difference between HDMI cables?
For a given resolution within the cable's bandwidth limit there is no picture-quality difference, because HDMI is digital — the image either arrives intact or it does not. What matters is whether the cable has enough bandwidth and is built well enough to carry it reliably. Beyond that, expensive cables do not improve the picture.
How can I tell if an HDMI cable is genuinely Ultra High Speed?
Look for the Ultra High Speed HDMI Certification Label on the packaging. It carries a holographic seal and a QR code you can scan with the HDMI authentication app to confirm the cable passed the 48 Gbps certification program.
How long can an HDMI cable be?
A passive copper HDMI cable reliably carries high-bandwidth signals (4K and up) for about 3 to 5 meters; lower resolutions go farther. For longer runs use an Active HDMI cable or an Active Optical (AOC) HDMI cable, which extend the signal to tens of meters.
