4K HDMI Matrix Extender 4x4 4K60Hz Over CAT6/7/8 - Matrix Splitter

In this review the MT-VIKI 4K HDMI Matrix Extender is presented as a professional AV distribution unit for installations that need multiple inputs and long cable runs. The bottom line: it is aimed at integrators and venues that want reliable 4K@60 4:4:4 distribution over Ethernet cable while minimizing power clutter, because a single power adapter supplies the main unit and 12V POC powers all CAT ports to the receivers. The reviewer found it best for fixed installations where hot-plug convenience is not required and where IR, RS232 and web control integration matter.

Key Features

• 4x4 plus extended outputs: Four HDMI inputs with 12 total outputs (4 local loop out at the matrix plus 8 extended outputs over CAT cable) give flexible local and remote display routing.
• Long-distance 4K distribution: Sends 4K@60 4:4:4 signals over CAT5e/6/7/8 up to 230ft (70m), suitable for many commercial runs without repeated signal converters.
• Single adapter with POC: One power adapter operates the whole system while 12V POC on all CAT ports powers the receivers, reducing the number of power bricks needed on site.
• Multiple control methods: Control by front panel buttons, IR remote, Web GUI, RS232 and an Android app provides integration flexibility for control systems and installers.
• Audio embedding and separation: Built-in audio input and output ports support external amplifiers and allow audio embedding or de-embedding for sound system integration.
• EDID and format support: EDID management and simultaneous support for 4K and 1080p outputs help compatibility when mixing legacy and modern displays.

Who It's For

The MT-VIKI matrix is best for small to medium commercial installations such as churches, sports bars, casinos and hotels where multiple sources must be routed to many displays and long cable runs are common. Installers who value a single-power solution and advanced control options will appreciate the included RS232 and Web GUI for automation.

It is not ideal for users who expect hot-plug convenience or need an iOS app; the unit does not support hot-plug & play and the vendor supplies an Android app only. Home hobbyists who need simple, consumer plug-and-play switching may find the setup and control options more complex than necessary.

Pros & Cons

Pros

• Delivers true 4K@60 4:4:4 over CAT cable to 230ft, suitable for high-quality video distribution.
• Single power adapter with 12V POC reduces power points at remote receivers.
• Comprehensive control options including Web GUI and RS232 support professional integration.
• Audio embedding/de-embedding enables connection to external amplifiers and sound systems.

Cons

• Does not support hot-plug & play, so sources and displays should be powered and stable during configuration.
• Mobile control is limited to Android; there is no iOS app provided.
