Questions about this item

Will this 100ft HDMI 2.1 hybrid active optical cable work with my older 4K display and AV receiver?

The cable supports HDMI 2.1 features including 48Gbps bandwidth, HDR10+, eARC for 7.1 and 32-channel audio, and HDCP 2.3. It is backward compatible with earlier HDMI versions, so it will function with your existing 4K display and receiver at their maximum supported capabilities.

How can I verify the cable is delivering the full 48Gbps bandwidth and HDR10+ after installation?

On your source device, open the display information or EDID overlay to confirm the link reports 48Gbps (FRL 6) and 12-bit colour depth. Play HDR10+ test content and check the TV's info banner shows HDR10+ active. For audio, ensure the receiver indicates eARC and 7.1 or 32-channel PCM.

What comes in the box with this StarTech 8KA100FHDMICABLE, and do I need to buy a separate power adapter?

The package contains the 100ft hybrid active optical HDMI cable with integrated transceivers. No external power adapter is required; the cable draws power from the HDMI source and sink ports. No additional cables or accessories are included.
