I used four 27" monitors together in 2x2 mode and so far so good. Audio is being passed through the SPDIF port and functioning well. The remote works fine, but I don't really use it. I keep it in 2x2 mode and don't change it. I am just waiting to get four 83" TV's together to make a giant movie screen lol5 out of 5 stars.

I do various stage performances or studio set ups. I struggle with either having a display large enough or a bright enough picture via projector. I figured this would be a good way to be able to solve my problems by combining 4 large TVs together to make one big picture.I like many features of this. First, it has many options. I could do 4 TVs in a 2 x 2 grid, OR if I wanted something a little different I could do 3 TVs on their side and have the screens rotated. I had seen this configuration in museums before where they have 3 TVs on a computer and the screens were angled so it was a semi-circle. While I don’t have plans to do that right now, it is nice to have that possibility.I was easy to hook up and configure. You plug everything in and it just works. You can use the remote to pick the setting you want or just keep pressing the front button. I liked how the back had little green lights near the plugs to show that the signal was properly connected, which could help in troubleshooting if there ever is a problem.I am looking forward to seeing the different ways I can make use of this!

Easy to connect multiple devices for connecting/splicing screens. Easy to assemble, comes with everything needed to complete the job-inclining a remote. Instructions also easy to ready and user friendly. Durable, well made, and easy to use. Pretty decent price.
