Questions
- What bandwidth and resolutions does it carry?
- HDMI 2.1 at 48Gbps, four channels of 12Gbps, supporting 8K@60Hz, 4K@120Hz and 4K@144Hz, with HDCP 2.2 and backward compatibility.
- Which HDR formats pass?
- HDR10, HDR10+, Dolby Vision and HLG.
- Does it support eARC?
- Yes, Enhanced Audio Return Channel is fully supported.
- What is the optical arrangement inside?
- A four-channel 850nm VCSEL array over OM3 fibre and copper hybrid, 4.5mm outside diameter, in black.
- Does it need external power?
- No. It is bus-powered from the HDMI source, drawing 250mW at most.
- How long is this version?
- 30 metres (98 ft.).
- No picture appears when the cable is fitted.
- The cable is directional. The source end must be at the source; reversed, it will not pass signal.
- 8K content will not display.
- 8K@60Hz needs the full 48Gbps link at both ends. Confirm the source and the display are HDMI 2.1 devices.
- What temperature range is it rated for?
- 0 to +50 degrees C.
- Can it run in a wall or conduit?
- Yes. It is a 4.5mm hybrid fibre and copper cable, bus-powered, so no supply is needed along the route.
