Good Connections Ultra High Speed HDMI 2.1 Cable, 0.5 m

A short 48 Gbps jumper for racks, AV cabinets and devices stacked right next to the screen.
48 Gbps8K @ 60 Hz DSC0.5 m

The Good Connections 4521-005 is a 0.5 m Ultra High Speed HDMI 2.1 cable with HDMI Type A male plugs, tested for the full 48 Gbps signalling rate (38.4 Gbps net data). It carries 8K at 30 Hz 4:4:4 or 8K at 60 Hz with DSC and uses 30 AWG conductors with foil, braid and drain-wire shielding in a black PVC jacket.

Compatibility Note: 0.5 m is very short — measure the route between ports first. Getting 4K 120 Hz or 8K also requires both the source and the display to support HDMI 2.1 FRL.

Frequently Asked Questions

Why is the Good Connections 4521-005 listed as 38.4 Gbit/s if it is a 48 Gbps cable?
48 Gbps is the HDMI 2.1 FRL signalling rate; after 16b/18b encoding the usable data payload is about 38.4 Gbit/s. Both figures describe the same Ultra High Speed performance.
Is a 0.5 m HDMI 2.1 cable useful for a PS5 or gaming PC?
Yes, when the console or PC sits directly below the TV or in the same rack as an AV receiver — a short cable avoids clutter while supporting high-refresh 4K modes.
Singular Expert Insight
A neat, short jumper when you need full HDMI 2.1 bandwidth between a receiver and a TV, or a console in a cabinet right under the screen. For longer runs pick the same 4521 series at 1–3 m rather than a lower-spec cable.
✓ Buy it if your devices are within half a metre and you want 48 Gbps headroom.
✕ Skip it if you need more reach — 0.5 m leaves no slack for wall mounts.
→ Also consider Good Connections 4521-020 (2 m) or 4521-SF010B SmartFLEX (1 m, flexible).
