MT-VIKI 8x8 4K Seamless HDMI Matrix Video Wall 2x4 w/Web GUI+Audio Out, Customised HDMI TV Wall Controller, Rack Mount Matrix Switcher Splitter Support RS232, APP, IR Remote, Web

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

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.
