Frequently Asked Questions

What makes the SmartFLEX version different from the standard 4521 cable?
Both are 48 Gbps HDMI 2.1 cables. SmartFLEX adds a softer, more flexible jacket and aluminium plug housings in dark blue, which makes tight bends behind equipment easier; the standard 4521 series has a black PVC jacket.
Is 0.5 m long enough to connect a console to a TV?
Only if the console sits directly below or beside the TV input. For most TV cabinets 1–2 m is safer; the 4521-SF010B (1 m) and 4521-SF020B (2 m) are the same cable in longer lengths.
Singular Expert Insight
The 4521-SF005B is a neat choice for rack, desk and AV-cabinet jumpers where a short, flexible 48 Gbps cable avoids clutter. It is not officially certified, but Good Connections builds it to the full HDMI 2.1 feature set. Browse more in our HDMI cables and adapters.
✓ Buy it if you need a very short, flexible HDMI 2.1 jumper for 4K 120/240 Hz or 8K sources.
✕ Skip it if your devices are more than about 40 cm apart, or you require an official certification label.
→ Also consider Good Connections 4521-SF010B (1 m) or 4521-010 (1 m, black).
