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

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.

Fantastic video wall controller! Easy to set up, supports multiple layouts, and handles 4K input smoothly. The rotation feature control make it very versatile.

Item worked once, sat for a couple weeks now doesn’t even work .

The product felt cheap, but did what it needed to. Because of the confusing lay out of the settings and the remote it made it difficult for my workflow. But worked in the end had 4 screens stacked 2x2. Again just a little confusing to understand the settings

This video wall display worked to combine multiple HDMI feeds into one. I had better luck using a 1920x1080 video feed. I tried this on a 3440x1440 display and the video was stretched out and didn't look quite right, but on HD it looks great. The remote lets you control how the screens are displayed, and whether to mask the edges or not. The edge masking is a useful feature that is missing from other video walls in this price range. This video wall display would work well for a permanent TV setup.

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.

This is really a good idea to add four smaller TVs instead of buying 100''. This works really well without delay. Quality is really good. no sound delay. Very easy to configure and use. Good product at this price.
