I have two large monitors of 32 inches and two small extended latptop monitors of 17 inches. I frequently need to use them for my office laptop and my personal laptop and swithch between them multiple times. I bought this wall controller to connect multiple monitors at the same time. This works really good and I can set and change the rotation and scaling of the monitors and choose to use given monitors at a given time. This really boost the productivity and eases to work with multiple monitors. The picture quality is great and I see this device very useful.

Great video control picture quality the sound quality and the speed will come together very good the display at 2×2 or 4K and comparable with HDMI and DVI or 4K are also amazing. Can suit anyone since it basically works with any display.

Excellent, bought to replace a $500 dollar unit and does the exact same job. Splits screens easily.

The description pretty clearly states that it can split a single 4k input into up to four 1080p outputs, but no combination of settings actually does that. In 4k mode, my 1080p monitors just show "out of range", so it must be switching both the input and output to 4k (I don't have a 4k monitor to verify). In 1080p mode, it sort of works in 2x2--except that it's just scaled 1080p so it's super fuzzy. In 1x1 mode it works as a 4-way splitter with decent-ish quality... but every other arrangement option is as fuzzy as 2x2 and also stretched either horizontally or vertically. I even went pretty deep into my graphics card settings to define custom resolutions matching what was in the description (i.e 3840x1080 for 1x2), and that actually made the distortion worse. If you have 4k monitors and you want to take a gamble, then maybe your results will be different... but it definitely doesn't work as advertised with 1080p monitors.

This was very easy to set up and connected to all my screens well. It’s a great value for its money. And does exactly what it’s supposed to do. The remote has good pickup. And the sound quality is good. It has clear picture quality as well.
