When it comes to AV installations whether you’re setting up a corporate boardroom, a digital classroom, or a retail display—the wrong HDMI cable can bottleneck your entire system. Not all HDMI cables are made equal, and with so many versions and specifications floating around, it’s easy to overpay or under-deliver.
Here’s what you actually need to know.
1. Start with Your Source and Display
First, understand what your devices support. Are you working with 1080p Full HD, 4K, or even 8K? Do they support HDR (High Dynamic Range), ARC (Audio Return Channel), or eARC?
For example:
- If you’re connecting a basic laptop to a Full HD display, a standard High-Speed HDMI cable works just fine.
- For 4K@60Hz or HDR content from a media player to a large-format display, look for Premium High-Speed or Ultra High-Speed HDMI cables.
Pro tip: Always check the HDMI version supported by both your source and sink (display or AV receiver).
2. Understand the HDMI Cable Types
Here’s a simplified breakdown:
| Cable Type | Use Case |
|---|---|
| Standard HDMI | 720p/1080i legacy systems |
| High-Speed HDMI | Up to 1080p, 4K@30Hz, HDR |
| Premium High-Speed | 4K@60Hz, HDR, better shielding |
| Ultra High-Speed | 8K@60Hz, 4K@120Hz, Dynamic HDR, eARC |
If you’re future-proofing a new AV setup, Ultra High-Speed HDMI is worth considering, even if your current system doesn’t need it today.
3. Cable Length Matters
Not all cables perform equally over long distances. Signal degradation is a real issue after ~15 feet (5 meters), especially with 4K or higher resolutions.
If your installation spans across a conference room or auditorium:
- Use Active HDMI cables or HDMI over Cat6 extenders for long runs.
- Avoid coiling long cables tightly or running them parallel to power lines.
4. HDMI Certification is Key
Look for cables that are HDMI.org certified. These undergo testing for bandwidth, EMI shielding, and signal integrity. Counterfeit or cheap unbranded cables often claim high performance but don’t meet the standards.
For professional installs, it’s worth sticking to known brands with proper labeling and QR-code verification.
5. Match with Your AV Goals
Ask yourself:
- Is this for video conferencing?
- Will it carry both video and audio to a soundbar or AV receiver?
- Is latency a concern for live production or gaming?
Based on that, you might need features like Ethernet over HDMI, ARC/eARC, or Low Latency support, which not all cables provide.
