4x4 hdmi matrix + video wall +multiviewer

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!

It doesn’t work for video wall not a lot of help was provided on this device will be returned mind

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 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.

bought this specifically for my man cave. Seamless switching from one feed to another is instant with zero lag. I wish I could program the function buttons on remote, but other than that works great.

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.

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.

This product should be removed by Amazon for false information. There is nothing 4K about this device.

This device makes it much easier to switch between my devices. It has a video wall option and multiview, which makes it feel useful for around the house. I mostly use it for swapping between my consoles and streaming devices and I also like how myself and my husband can watch different things at the same time if needed. It was super easy to set up and I like that you can control it through the web page or the app making it a nice and easy thing to confrol. You can also use the rotation feature to change the layouts on the screen which helped when sitting on different sofas. The image quality is ok but to me it doesn’t quite look like full 4K. It’s fine for watching shows or gaming but I do notice compared to when something is plugged directly into the TV.

Performed as expected
