Likes: It’s very easy to install and comes with step by step instructions on how to hook it up. It is perfect and made a perfect gaming set up for my little boy. The picture quality is stunning. It performs exactly as it says that it should. It is made of really durable material making it the best quality. I love that there see different options on how to control the box and comes with a remote control. I've been using it for 2 months before I came to review it, and the effect is really fantastic. I really like it and it is most definitely worth the money. I also use this to create the perfect at home theater for my family and it’s amazing. Dislikes: It really is hard to find any flaws in the video wall controller but I do wish that they offered one where you can connect between two and six monitors but that doesn’t take away from how amazing this is and how much easier it makes gaming and creating an in home theater!

The Riuiin 4K30hz video wall controller delivers exactly what it promises — seamless 4K UHD display across up to four TVs. I set up a 2x2 video wall for my home media room, and the picture quality is stunning with zero lag or glitches. It supports multiple input types, including HDMI and USB-C, which makes connecting various devices a breeze. Switching layouts like 1x2 or 4x1 is quick and intuitive. The unit feels solidly built and runs cool during extended use. Whether for professional presentations or immersive entertainment, this controller makes managing multiple screens simple and professional-grade.

I am so disappointed in this product right now. This product came with no instructions manual. So I am just pressing different buttons to see if anything will work. The main one right now is that I cannot get it to rotate the images. In addition, the picture quality is the worst. I am so freaking upset because I kept this product unused for so long, now it’s past the return deadline and I am pretty much stuck with a non functional item. You cannot find anything on YouTube either; that should have been my clue before purchasing it. I guess I get to learn the hard way.

Well, let me tell you, when I saw that blank wall in my basement, I knew I had to do something epic. And you know what? I went all out and got four 75-inch screens to take up that space. And lemme tell ya, it was a total game-changer! Not only did those screens fill the wall like a perfect puzzle piece, but they turned my basement into a private IMAX theater! Whether I’m binge-watching my favorite shows, gaming with my buddies, or even video chatting with my mom, it’s like I’m in the middle of Hollywood. So yeah, I’m totally loving this purchase. It’s not just a wall of TVs, it’s an experience. Every time my friends come over, they’re like, “Woah, dude! This is amazing!” And I just sit back and smile, knowing I made the right choice. This basement is now the ultimate entertainment hub, and I’m loving every minute of it!

This is really cool and easy to use. I set it up with a few monitors, and it worked right away without any problems. The picture looks super clear, and switching between the different screen layouts with the remote is really simple. It’s perfect for school projects, gaming setups, or any kind of display wall.

The first one I got the remote control did not work. Unit powered up, but I couldn’t get it to do ANYTHING because the remote did not work. The battery was fine BTW. I started the return process and asked for a replacement. Got it quickly enough, but it also did not work. This time my monitor would only flash white, red, blue, & green repeatedly. Again, the remote control did nothing. Initiated a second return with a refund this time. Cannot recommend this product. UPDATE: After I posted this review I was contacted by the seller. They apologized for the problems I was experiencing and offered to send me a new replacement at no charge. I ran it through a thorough series of tests and can confirm that it worked, but not with a caveat. My main interest in this unit was to use it with three wall mounted side-by-side monitors in my windowless studio. I wanted to display outdoor photos on them to make them virtual "windows." However, this unit would stretch out the image due to the fact that it is limited to a maximum display of 1920 X 1080. It is not a scaler, so there was no way to un-stretch the image. I tried various resolutions and work-arounds, but finally found that they only was to obtain a non-stretched image was to crop it for a 3:1 aspect ratio and then "squish" it in Photoshop. That did the trick! Now, I realize this is a rather special case scenario. I'm working with photos, but I image the same trick can be employed with video if your editing software allows for such transformation. I suspect most people will want to use this for creating a 2X2 video wall, and in that regard I was able to partially test that configuration on my three monitors, and can say that it worked well. Given the low cost of the unit, I can say that it is a good buy and will work for most applications, and for that reason I give it 4 stars. It would've been nice if there was better documentation informing me of the stretching issue. However, their customer service was excellent, and for that I give 5 stars! The photos show the stretched and unstretched configurations. There are some black bars on either end of the unstretched photo which I should be able to get rid of with some more tweaking.

Does what is needed. Great product at a great price

I bought this to use at our church where we have a 2X3 setup with 6 TVs. In order to minimize gaps between TVs we setup our top TVs to be flipped upside down. I was greatly disappointed to discover that this device will not rotate the image unless you have a 3X3 configuration.

Blurry video, and it doesn’t send the correct resolution to the computer, so if you want a 1x2 it doesn’t allow you to select 3840x1080. Even if you set it to 2x2 and give it a 3840x2160 input, the picture is very bad.

Product did not work out of the box, Junk, had it for over 30 days before was able install the video wall so no warranty as it says 30 days. There were cheaper units but I figured if I spent more hoping it would be a better unit. Its unfortunate I could not utilize the unit, Beware! Following this product review the company reached out and refunded me my money. Thank You I appreciate you backing your product! I did some troubleshooting with the wall controller and tested the power supply which tested ok, then plugged the power back into it, wiggled it around and the lights flashed. I removed the circuit board from the box and found that one connection was not soldered properly from the power plugin to the circuit board. I resoldered it and tried it again, was better but 1 more contact not soldered, soldered it and it works fine. I will keep it as a spare if its ever needed. Its probably an excellent product just an issue at the manufacturing stage or it was damaged in transport. Who's to know
