4K HDMI Splitter 1x4 with EDID - Mirror 4K@60Hz to Four Displays

In this review the 4K HDMI Splitter 1x4 with EDID is evaluated as a practical, no-nonsense HDMI duplicator for anyone who needs to mirror a single source across multiple displays. The bottom line: it does exactly what it promises - reliable, true 4K@60Hz mirroring with minimal setup and useful EDID controls - making it a strong choice for small meeting rooms, classrooms, retail displays or portable AV rigs where consistent resolution and audio passthrough matter.

Key Features

• True 4K UHD: Mirrors one HDMI source to four outputs in full 4K@60Hz 4:4:4 for zero-latency viewing across all connected displays.
• HDMI 2.0 & HDCP 2.3: Uses 18 Gbps bandwidth so protected streaming, Blu-ray or gaming sources play back without handshake or bandwidth issues.
• HDR and Dolby Vision support: Preserves HDR10 and Dolby Vision metadata so color depth and contrast remain accurate on capable displays.
• Lossless audio passthrough: Supports DTS-HD, Dolby TrueHD, LPCM 7.1 and other formats so AV receivers and TVs receive full-quality sound.
• Smart EDID management: Eight DIP-switch EDID presets let the splitter match source and sink resolutions quickly, avoiding unsupported modes and blank screens.
• Portable rugged design: Compact metal housing with anti-interference shielding and a 5 V/2 A adapter makes it simple to install or carry between venues.

Who It's For

This unit is aimed at integrators, small business owners, educators and AV hobbyists who need to duplicate a single HDMI feed to up to four displays without latency or complicated configuration. It is especially useful when consistent 4K output and reliable HDCP handling are required across TVs, projectors or signage screens.

Those who need advanced matrix switching, per-output scaling, or long-run fiber/HDBaseT distribution should look elsewhere, as this device is a one-in/four-out duplicator intended for short-to-moderate cable runs using HDMI 2.0 or higher-rated cables.

Pros & Cons

Pros

• Delivers stable 4K@60Hz 4:4:4 across four outputs with low latency and no frame loss.
• Robust audio passthrough supports high-resolution formats for cinema-quality sound when connected to an AVR.
• EDID DIP-switch presets simplify setup and avoid display mismatches without menus.
• Compact metal chassis and included 5 V/2 A adapter make it easy to deploy or transport.

Cons

• Not a matrix switcher; it only duplicates one source to all four outputs rather than routing different sources to different displays.
• Suits typical HDMI cable lengths; very long runs may require signal extenders or higher-spec cabling.

Frequently Asked Questions

Will this splitter pass HDR and Dolby Vision?
Yes. It supports HDR10 and Dolby Vision metadata and passes HDR content when connected to compatible displays.

Do I need special cables for 4K@60Hz?
Use HDMI 2.0 or higher specification cables to ensure full 4K@60Hz 4:4:4 performance over typical cable lengths.

Can it route different sources to different displays?
No. This device duplicates one input to four identical outputs; it is not a matrix switcher.
