Video Wall Controller, 4K 2X2 TV Wall Processor with HDMI+DVI+RS232 Input, Support 180° Rotate, 4 HDMI Output Support Images Stitching 1x2 1x3 1x4 4x1 etc

This is a neat device and stitches together a small set (2x2) of monitors very nicely. It's not something that I would have thought about picking up if it weren't put in front of me, but for me it's a pretty nifty gadget.

This unit stitches multiple displays, vertically and horizontally up to a 4x4 display. A unique feature is to connect two displays vertically side by side as a very thin seamed monitor. Recommended for versatility.

I like this display box and it's easy to use. I feel it definitely serves the purpose of what it's intended to do!I believe I will end up upgrading to a 2x3 or larger version, however, as the 2x2 is a little limiting for our application. I do feel for the price the 2x2 would be a great option for a lot of users!

Everything worked great! Worked perfectly for our application. No issues and seems to be well manufactured. If you need a video wall controller then definitely look to purchase this one.

This video wall controller is pretty handy for setting up a big display. It handles high-resolution inputs well and has some cool features like rotation support. It’s a bit complex to set up, but once you get it going, it works smoothly. It’s a solid choice if you need to manage multiple screens, though it might take a bit of tinkering to get everything just right.

Offer flexibility for different scenarios, in my case I needed a 1×2 setting, works perfectly. I love the 180⁰ feature. Was able to place the second upside down to reduce frame width. I then rotated the signal 180⁰ and the image was beautifully projected. I have screens with thin frames, so it is almost unnoticeable from a distance.

Works great, performs as stated. The received video is high quality with little to no lag. It shows up to 4 screens and will seamlessly split between screens with the remote. Great product and easy to use. Great buy.

This unit works as advertised. The user guide is very small so expect to have your magnifying glass or expand it with a copier.Connections are easy and the included USB-C cable and power adapter are pretty standard these days so that makes it nice not having to worry about a special power cable.Connection with DVI or HDMI for input is pretty straight forward and there are 4 HDMI outputs depending on your configuration. Connecting to a MacBook, the device shows up as a monitor and you can select the appropriate resolution for the input image. The device does the magic of dividing this input across the number of monitors or TVs you have connected.I was hoping to connect two 27 inch monitors together for use with my MacBook since I already have a 32 Inch 4K monitor I can only have one additional monitor. This would have allowed me to have more real estate...BUT...the resulting picture is distorted since it splits the image across the screens. I was unable to select a resolution that would result in a good picture across the two monitors. For example, if the monitor supports 1920x1080 I would like to have a resolution from the MacBook of 3960x1080 so the height would be good the the with would be doubled so split across 2 monitors the resolution would look normal. However, that resolution is not doable and so the split image is always two wide and distorted.This device is probably not the best for my application, but it does do what it is designed to do in other situations.
