Monoprice Blackbird 4K HDMI 1x2 Amplifier Splitter

The Monoprice Blackbird 4K 1x2 HDMI Amplifier Splitter sends one HDMI source to two displays without losing 4K, 3D, or high-bit-depth color capabilities.

Whether you need the same video feed on two TVs, monitors, or projectors, the Blackbird 4K splitter amplifies and duplicates a single HDMI input to two HDMI outputs while maintaining high-resolution video, deep color, and multi-channel audio formats. It’s a compact, HDMI 1.4–class device designed to preserve signal quality across short-to-moderate cable runs and simplify multi-screen setups in home theaters, conference rooms, or retail displays.

How does the Blackbird 4K keep picture quality when splitting to two screens?

The unit includes an HDMI amplifier that boosts the signal so both connected displays receive the same image with minimal degradation. It supports higher bandwidth features of HDMI 1.4, including deep color and 3D formats, so color depth and frame packing-compatible 3D remain intact on both outputs.

• HDCP 1.4 compliant to work with protected content.
• Supports 48-bit Deep Color for richer color gradations.
• 3D frame-packing and other 3D formats up to a 297 MHz TMDS clock.
• Supported resolutions include 4K@30Hz and 1080p@120Hz.

Which video and audio formats will this splitter handle?

The Blackbird 4K accepts a single HDMI input and routes full HDMI audio and video data to both outputs. It passes common uncompressed and lossless audio formats so you can keep immersive sound when your displays or receivers support them.

• Video: up to 4K@30Hz, 1080p@120Hz, and 3D-1080p@60Hz.
• Color: 48-bit Deep Color support for better gradients.
• Audio: DTS-HD, Dolby TrueHD, 7.1 LPCM, DTS, Dolby AC-3, and DSD support.
• Works with HDCP 1.4 protected sources and displays.

Will it work with different display types and cable lengths?

The Blackbird 4K is designed for straightforward compatibility with HDTVs, monitors, and projectors that accept HDMI input. Because it’s an amplifier-type splitter, it extends the reach and reliability of a single source across two outputs better than passive splitters, but very long cable runs or older cables can still reduce signal integrity.

• Best performance with high-speed HDMI cables meeting 1.4 specifications.
• Recommended for short-to-moderate cable lengths; consider signal extenders for very long runs.
• Plug-and-play—no drivers or software required.
• Compact housing fits near source devices or AV racks.

How simple is installation and can it handle protected content?

Installation is quick: connect your HDMI source to the input, run two HDMI cables to your displays, and power the unit. The Blackbird 4K supports HDCP 1.4, so most Blu-ray players, streaming boxes, and consoles with HDCP-protected content will pass through correctly when the connected displays also support HDCP.

• Connect source to the single HDMI input; outputs mirror that signal.
• HDCP 1.4 compatibility for protected media playback.
• No configuration required—automatic handshake with displays.
• Indicator LEDs show active connections (depending on model variant).

Who is this for? The Monoprice Blackbird 4K 1x2 HDMI Amplifier Splitter is ideal for homeowners, small businesses, and AV integrators needing a reliable, affordable way to duplicate a single HDMI source to two screens without sacrificing 4K, deep color, 3D formats, or high-resolution audio. Choose it for dual-zone viewing, mirrored conference-room displays, retail looped signage, or any scenario where one source must drive two HDMI sinks simultaneously.
