HDMI Matrix 4 in 4 out +Video wall controller 2x2+ 4x1 HDMI Multiviewer

For general consumer use this is probably overkill, but maintaining an active connection with all the inputs makes all the difference when one or more of those requires a physical disconnection and reconnection to redetect settings every time you switch. Bonus: almost no delay when I switch.

It works but it doesn’t do everything that it says it will do. It doesn’t rotate the screens(you can’t mount the top TVs upside down). You can’t make the top two screens combine and have something different on the bottom screens. The only options you have is one big combined screen or 4 separate screens.

This is an excellent matrix switch. It switches between 8 inputs and outputs easily with the remote control or by the front panel. It has a lan connection as well as a serial input for more advanced configurations. I simply use mine as a switch using the remote control. It's nice to be able to send any input to any of up to 8 monitors. Note that if you are planning on using this in a quiet office that it's going to be a bit loud. This has a fan that is fairly loud. I think this may have been designed for more of a commercial environment. I have a 4x4 version of this which is silent and has no fan. I'm going to swap the fan out for a quieter Noctua fan or similar. Other than that, this thing is super easy to use. Just punch a button for the input and a button for the output for basic use. More complex setups can be configured.

As someone who's recently been looking to boost my online presence, particularly for livestreams, finding the right tech upgrades can be a daunting task. However, the MT-VIKI Video Wall Controller (2024 Version) has been an absolute game-changer and has exceeded my expectations. This device offers four display modes - Split, Splicer, Seamless matrix, and Bypass matrix - making it incredibly versatile. The standout for me is the seamless matrix mode, which supports seamless switching and maintains superb video quality, crucial for smooth, professional-looking streams. The setup also includes a split function on OUTPUT 1 with an impressive 23 split modes, such as PIP, POP, and Quad-view, which have really enhanced my ability to present varied content simultaneously. While it's noteworthy that the 0°/90°/180°/270° screen rotation function only works on a single split screen and only at resolutions up to 1080P, this hasn’t been a significant limitation in practice as of yet. Furthermore, the device functions wonderfully as a video wall controller, supporting multiple splicing modes which can be handy for more complex visual setups. Also, audio support is robust, accommodating PCM, Dolby AC3, DTS5.1, DTS7.1, and DSD audio formats, which is great for ensuring high-quality sound during livestreams. The package comes complete with all necessary accessories, including an IR remote, RS232 cable, and rack ears & screws for easy installation. In summary, the MT-VIKI Video Wall Controller has proven to be an invaluable addition to my setup, significantly enhancing my streaming quality with no lag time and a lot of flexibility. It's an investment that I feel is well worth it for anyone serious about upgrading their online video capabilities.

I recently set up the MT-VIKI 4K 4×4 HDMI Matrix in my home studio, and it has been amazing. The ability to route any of four HDMI sources to four displays at once, plus the built-in 2×2 video wall and multiviewer with picture-in-picture, gives me full control over every feed—analytics, camera, and live preview—all at the same time. Standout Features: Flawless 4K@30Hz performance, with zero lag or visual glitches. Smooth support for 90°/180°/270° screen rotation, ideal for unique monitor setups or digital signage. Intuitive web GUI and mobile app, making it easy to switch layouts, sources, and overlays on-the-fly. Integrated 3.5 mm stereo audio out, giving me the flexibility to send audio through an external amp or mixer alongside video. Rock-solid build quality in a compact case—no overheating or lag during intensive use. Whether I’m running presentations, streaming multi-camera content, or managing a video wall, this unit handles everything with ease. If you need a versatile, seamless coordinator for 4K video routing and layout control, the MT-VIKI HDMI matrix is a powerhouse—reliable, feature-rich, and great value. Highly recommended for studios, home theaters, pro installers, or tech enthusiasts!

I’m hoping that I can revise this review if someone from the company can correct this issue. The description clearly shows that this supports video wall functionality - which is why we purchased. The software that is included on the device to control the video wall was different than what was provided in the instructions and was missing the “video wall” tab. If someone from the company can please correct this would be appreciated - otherwise it’s going to be returned

This switcher has a variety of modes that allow this to function as a multiviewer, video wall controller, or a standard matrix switch. 4K30 inputs work, but I need 60Hz refresh, so I run this at 1080p60. It works great with my 1080p sources as a matrix switch, and I like the option to run in other modes if needed.

Performed as expected

下位機種からの乗り換えですが問題なく動作しています。音声出力があるのでうれしい。 使用目的の4outと4inの組み合わせのメモリー切り替えはできています。 他の設定には取り組んでいませんがやや面倒な気がします。
