Generic 4K HDMI Splitter 1x4 with Audio Extractor

This 1x4 4K HDMI splitter duplicates a single HDMI source to four displays while offering optical and 3.5mm audio extraction, per-output downscaling, EDID control, and HDCP 2.2 compatibility.

Designed for home theaters, classrooms, retail, and small AV installations, the Generic 4K HDMI Splitter 1x4 delivers synchronized video to up to four screens at up to 4K@60Hz HDR while letting you route sound to a separate audio system. It combines HDMI 2.0 bandwidth (18 Gbps), programmable EDID handling, and a built-in audio extractor so mixed-resolution environments and legacy audio gear can coexist without manual format juggling.

How does this splitter maintain picture quality across four screens?

The splitter uses HDMI 2.0 bandwidth and hardware-level duplication to transmit the source signal to four outputs with minimal latency. It supports 4K@60Hz 4:4:4 with HDR10 and HLG for vivid colors and sharp detail, and it’s backward compatible with 1080p and 720p displays.

• 4K@60Hz 4:4:4 support for high-fidelity video.
• HDR10 and HLG pass-through for wider dynamic range.
• 18 Gbps HDMI 2.0 throughput avoids bottlenecking high-bitrate sources.
• Backward compatibility with 1080p/720p displays.

Can I extract audio for a soundbar or amplifier?

Yes — the built-in audio extractor provides both optical (TOSLINK) and 3.5mm stereo outputs so you can send multichannel or compressed audio to external systems. This is useful when a display lacks adequate audio outputs or when you prefer a separate audio processor or legacy amp.

• TOSLINK output for digital multichannel audio and reduced interference.
• 3.5mm stereo output for older soundbars and amplifiers.
• Compatible with Dolby TrueHD, DTS-HD Master Audio, and LPCM formats.
• No need to rely on HDMI ARC — direct extracted feed available.

How do downscaling and EDID options help mixed-display setups?

Each output can independently downscale 4K to 1080p, so you can connect older HDTVs alongside modern 4K monitors without forcing every screen to the highest resolution. Smart EDID modes (auto/copy) manage handshake and resolution negotiation to prevent black screens and unsupported format errors.

• Per-output 4K→1080p downscaling for mixed-resolution deployments.
• EDID auto and copy modes to match source and display capabilities.
• Dial switches and LEDs simplify configuration and status monitoring.
• Ideal for classrooms, showrooms, sports bars, and multi-room AV.

Which devices and protections does it support for future-proofing?

The unit implements HDCP 2.2 and HDCP 1.4 compatibility to work with modern streaming sticks, consoles, and Blu-ray players. With HDMI 2.0 and 18 Gbps capacity, it handles HDR content, 3D, and high-color-depth sources from devices like PS5, Xbox Series X, Apple TV 4K, and Roku Ultra.

• HDCP 2.2 support for protected 4K streaming sources.
• HDMI 2.0/1.4 compatibility across a wide device range.
• 18 Gbps bandwidth for HDR, wide color, and 3D formats.
• Metal case and active power supply for reliable, long-term operation.

Who is this for? AV integrators, small business owners, educators, and home theater enthusiasts who need a dependable way to mirror a single HDMI source across multiple screens while preserving audio flexibility and display compatibility. If you need per-output downscaling, optical or analog audio extraction, and HDCP 2.2 compliance in a compact metal enclosure with simple controls, this splitter is built for those mixed-resolution, multi-screen environments.

• Includes: HDMI splitter unit, power adapter, and user manual.
• Plug-and-play setup with no drivers required; works with Windows, macOS, Linux, and Chrome OS.
• 24-month replacement warranty and lifetime technical support from the manufacturer.
