MT-VIKI Video Wall Controller 3x3, Support 1080p 60Hz HDMI Output and 1 Input for 9 TV Splicing Display, 9 Channel Video Wall Processor

The MT-VIKI 4K Video Wall Controller 2x2 does a solid job of delivering crisp 4K output across multiple HDMI displays, with plenty of flexibility in how you set up your screen configuration. I've used it to power a 2x2 video wall with four TVs, and the image quality and responsiveness have been consistently impressive.It supports a wide range of display modes — 1x2, 1x3, 1x4, 2x2, 4x1, 3x1, and 2x1 — which makes it extremely versatile for different applications, from retail displays to home setups. The HDMI input and output both support up to 4K at 30Hz, and the video performance is clean and stable, with no noticeable lag or tearing.That said, while the device works well, it doesn't exactly scream premium quality when you unbox it. The build feels a bit plasticky and light, and considering the price point, I expected a more professional, solid construction. It looks and feels cheaper than it should, which might be disappointing if you're going for a polished setup.Also, the instructions are quite basic, and getting everything aligned and working may take a bit of trial and error — especially for less tech-savvy users. The remote works, but it’s minimal and not particularly user-friendly.All in all, this controller performs reliably and offers great flexibility, but just be aware that its physical presentation doesn’t quite live up to the price tag.

I'd originally ordered this with the hope of having the signal split between four screens for gaming on my PS5 but found that the maximum resolution was capped at 4k 30hz, this was lower than I had hoped and I'm not sure why they've done this as it's limiting with today's technology.It also prevents further devices in the future being able to send the maximum signal, however, it works very well at lower resolutions.It supports 1280x720 at 60hz and 1920x1080 at 60hz for example but 4k is only 30hz.I've been using this with my pc in a 1x2 output mode, this works perfectly and I have noticed zero issues with the splitting and the image stays true.It supports 1x1, 1x2, 2x1, 1x3, 3x1, 2x2, 1x4 and 4x1. This gives you pretty much every combination I can think of for stretching or duplication.You can manually switch using the mode button on the unit or it comes with a remote which works well too.It's very easy to install everything, simply attach your HDMI cables and that's it.My only issue is the maximum resolution and I'm knocking one star off but apart from that it's excellent for me.

Excellent quality picture - can't fault it.

4 port HDMI video wall splicerA brilliant little device, making it so you can split the signal from one source, simultaneously connecting 4 displays. Have all of the screens making one whole screen. The upper left is HDMI 1, upper right 2, lower left 3 and lower right 4.You have a few display options, 1280/720 at 60Hz, 1920/1080 at 60Hz, 3840/2160 at 30Hz. You have 8 splicing modes, which are quickly accessible through the remote, these are 1X1, 1X2, 2X1, 1X3, 3X1, 2X2, 1X4, 4X1.I do think this is a handy device. It seems well made and durable. It's a good small size at roughly 14.5cm x 8.5cm x 3cm.It's slightly more than I thought it would be but the design and quality is good and it has an easy set up too. So I would recommend it.

It has an easy setup . The device is small and durable. It can smoothly connect displays without any loss of resolution. It has 4 ports for the HDMI connection. This device supports multiple splicing. There is no lag or any loss of quality. I would recommend this device.
