4K HDMI Matrix Switch 4x4 - Flexible 4 In 4 Out Distribution

In this review the Yinker 4K HDMI Matrix Switch 4x4 is judged as a practical, no-nonsense option for small control rooms, home theater setups, and meeting spaces that need flexible routing of multiple HDMI sources. The single biggest reason to buy is straightforward: it routes any of four HDMI inputs to any of four outputs without replugging cables, so a user can operate as a switcher or a splitter with ease. The unit balances useful control options and EDID memory features while remaining compact and easy to set up.

Key Features

• 4 In 4 Out Matrix: Connects four HDMI sources and routes them to any combination of four displays so feeds can be distributed individually or mirrored simultaneously.
• 4K High Resolution: Supports up to 4Kx2K@30Hz and 1080P@60Hz downscale so sources and displays with different capabilities can work together.
• Three switching methods: Offers front-panel backlit buttons, an IR remote and RS232 control so users can switch sources locally or integrate with control systems.
• EDID Management: Auto-scan and built-in EDID formats plus save and recall for 16 display scenes help maintain compatible signals across mixed displays.
• Signal reach: Transfers HDMI signals up to about 50ft with standard HDMI cable and up to 65ft with HDMI fiber, making it suitable for small AV installations.

Who It's For

The Yinker 4x4 matrix is aimed at small offices, security or exhibition booths, and home AV enthusiasts who need to route multiple HDMI sources to several screens without swapping cables. It is useful where a modest rack or desktop device is required and where basic automation via RS232 and IR control is desirable.

It is less appropriate for users who need a video wall controller or who require 4K@60Hz and higher refresh rates. Also, those who need rack-mountable 1U hardware should look elsewhere because the compact 10 by 3.9 by 1.3 in enclosure is not intended for 1U mounting.

Pros & Cons

Pros

• Flexible routing of four inputs to four outputs without replugging, simplifying multi-display setups.
• Multiple control options including backlit front buttons, IR remote and RS232 for integration with automation.
• EDID save/recall and power-off memory maintain scenes and reduce configuration hassles in repeated use.
• Supports common audio formats and 4:4:4 color space for good compatibility with many sources.

Cons

• Maximum 4K is limited to 4K@30Hz, so it does not meet needs for 4K@60Hz applications or high-refresh gaming displays.
• Some users report mixed experiences with input behavior, indicating setup or source compatibility can require troubleshooting.

Frequently Asked Questions

Can this unit make a 2x2 video wall?
The unit is a matrix switch, not a video wall controller, so it cannot create a 2x2 TV wall layout.

Will it remember my configuration after power loss?
Yes, the matrix supports power-off memory and can save and recall up to 16 display scenes to restore routing after power cycles.

What switching options are available?
Switching can be done via the front-panel backlit buttons, the included IR remote, or RS232 control for integration with control systems.
