HDMI cables — common questions

Do you carry HDMI 2.1?

Yes — HDMI 2.0 (18 Gbps, 4K at 60 Hz) and HDMI 2.1 (48 Gbps, 4K at 120 Hz and 8K at 60 Hz), in Type A, C (mini), and D (micro) connectors.

Passive or active and optical cables — what is the range?

Passive copper to about 3 m, and active or optical (AOC) assemblies to 30 m for long runs without signal loss.

Are they HDMI ATC tested?

Yes. Assemblies are HDMI ATC (Authorized Test Center) tested and carry UL CL2 or CL3 in-wall ratings and RoHS where specified.

Which HDMI version do I need for 4K or 8K?

4K at 60 Hz runs on HDMI 2.0; 4K at 120 Hz and 8K at 60 Hz need the 48 Gbps bandwidth of HDMI 2.1. Tell us the resolution and refresh rate and we build to it.

Can you build custom lengths and branding?

Yes — length, jacket, connector type, and logo to spec, with origin documented per unit.
