Frequently Asked Questions

Is the Good Connections 4521-SF020B good for 4K@120Hz gaming?
Yes. It is specified for HDMI 2.1 bandwidth up to 48 Gbps, covering 4K@120Hz and even 4K@240Hz, with VRR and ALLM for consoles and gaming PCs connected to an HDMI 2.1 display.
What does SmartFLEX mean on the 4521-SF020B?
SmartFLEX is Good Connections' range with a soft, flexible PVC jacket and slim 6 mm diameter, so the cable bends easily behind TVs and on desks. The range also includes 4521-SF005B (0.5 m), 4521-SF010B (1 m) and 4521-SF015B (1.5 m).
Singular Expert Insight
The 4521-SF020B combines full HDMI 2.1 bandwidth with a thin, supple jacket, which makes it easier to route than stiff braided 8K cables. The manufacturer data we verified does not state an official Ultra High Speed certification, so we do not claim one.
✓ Buy it if you want a flexible 2 m HDMI 2.1 cable for 4K120/240 or 8K.
✕ Skip it if your equipment is HDMI 2.0 and 4K@60Hz is the limit.
→ Also consider Good Connections 4521-SF015B (1.5 m) from the same SmartFLEX range.
