What is the difference between Certified and Non-Certified HDMI 2.0 cables?
The difference mainly lies in materials, signal quality, and real 4K@60Hz 4:4:4 support. Non-certified cables often cut corners, while certified cables are tested to meet the full HDMI 2.0 standard.

Feature |
Non-Certified HDMI 2.0 Cable |
Certified HDMI 2.0 Cable |
|
Conductor Material |
Often uses BC or CCS (Copper Clad Steel) |
Uses only high-purity Bare Copper |
|
Wire Gauge (AWG) |
Lower AWG (thinner wire), higher resistance |
Higher AWG (thicker wire), lower resistance |
|
Signal Stability |
Unstable over 2–3 meters; signal degradation possible |
Stable signal over longer distances |
|
4K Support |
Supports only 4K@60Hz 4:2:0 (compressed color format) |
Supports 4K@60Hz 4:4:4 (full color, uncompressed format) |
|
Testing & Certification |
Only passes our basic 4K TV visual tests, not suitable for demanding applications |
Passes HDMI 2.0 Eye Pattern Test meets full HDMI ATC standards |
|
Cost |
Lower cost, suitable for casual 4K video use |
Slightly higher cost, ideal for gaming, monitors, and professional setups |
Conclusion:
If you're looking for cost-effective basic 8K compatibility for casual viewing, a Non-Certified cable may be sufficient.
If you need full bandwidth, color accuracy, and signal reliability for high-end or professional applications, a Premium Certified HDMI 2.0 cable is highly recommended.
What is the difference between 4K@60Hz 4:2:0 and 4K@60Hz 4:4:4?
The key difference is in color sampling – which directly affects image clarity and accuracy.
|
Format |
4K@60Hz 4:2:0 |
4K@60Hz 4:4:4 |
|
Color Sampling |
Chroma Subsampling 4:2:0 – color data is compressed to save bandwidth |
Full Chroma 4:4:4 – each pixel has full color info, no compression |
|
Image Quality |
Lower color precision, softer details, text may appear blurry |
Sharp, clean image – especially noticeable on text, UI, and fine details |
|
Bandwidth |
Lower bandwidth requirements – works on cheaper or thinner cables |
Requires full HDMI 2.0 bandwidth (18Gbps), needs a quality certified cable |
|
Use Case |
Movies, streaming, standard 4K TVs |
PC monitors, gaming, professional editing, digital signage |
✅ Summary:
So if your setup is demanding (like an 4K monitor or gaming rig), you’ll want a cable that supports 4K@60Hz 4:4:4, which requires certified HDMI 2.0 cables with full 48Gbps bandwidth.
