FAQs
Do I need this cable for a standard 4K TV?
While a standard HDMI 2.0 cable works for 4K@60Hz, this 8K cable is recommended if you want 4K@120Hz (for gaming) or if you want to future-proof your setup for 8K content.
Is this cable “Active” or “Passive”?
This is a passive cable. At 6 feet, a passive cable can easily handle the full 48Gbps bandwidth without needing an internal chip or external power.
Does it support Dolby Atmos?
Yes. Because it supports eARC (Enhanced Audio Return Channel), it can carry uncompressed Dolby Atmos signals from your TV back to your soundbar or AV receiver.
Is the nylon braiding stiff?
Anker’s double-braided nylon is designed to be flexible enough for easy routing while being tough enough to resist fraying and kinks.
