Blackbird 4K60 HDMI 70m Extender

The Monoprice Blackbird 144558 extends HDMI 2.0b signals up to 70 metres with zero latency. It supports 4K resolution at 60 Hz and HDCP 2.2 compliance for protected content. Audio extraction provides separate analogue output for external sound systems. The unit suits installers needing long-distance UHD distribution.

Sustained signal integrity over distance

ZeroLatency technology maintains uncompressed 4K60 RGB/YCbCr 4:4:4 video across the full 70 metre link without frame drops. Bidirectional Power over Cable delivers electricity through the same category cable, removing the need for local power at the receiver. EDID copy pass-through preserves display handshake stability during continuous operation.

Verify cabling and display compatibility

The extender requires solid-core category cable rated for the installed length to achieve 70 metres. Confirm the source outputs HDMI 2.0b and the sink accepts HDCP 2.2 to avoid handshake failures. Ensure the audio extraction format matches the connected amplifier or processor input requirements.

Questions about this item

How much power does the Blackbird 144558 extender draw when running 4K60 signals continuously over 70 metres?

The unit uses bidirectional Power over Cable so the receiver can be powered through the HDMI link, eliminating a separate power supply at the display end.

What cables and displays must I already have to use the 144558 extender at its full 4K60 70 metre capability?

You need HDMI 2.0b compatible source and display devices plus a single Category cable run of up to 70 metres between the transmitter and receiver units.

Will the 144558 extender pass through EDID and IR from my older 1080p projector without downscaling the 4K60 source?

EDID copy passthrough and IR forwarding are built in, so the source sees the projector’s native capabilities while the extender transports the 4K60 signal unchanged.
