Product worked great for me on two Proscan 40" LED televisions. There was some tweaking of the picture and color between the processor and the televisions because you essentially have double the settings, so you have to decrease a setting on one and increase on the other for a perfect color balance. The reason is, the red on the processor at 50 and red on the TV's at 50 = red at 100 all around. Trust me you do notice the high red on the actors lips its blinding red lol, and this goes as well for the other colors. On my setup I had to adjust the video aspect formats between the processor and the TV's as well and I believe I have these settings perfect for me. I recommend tuning these settings for different sources such as movies, games, and TV, then saving them to the processor and the same goes for the television settings. Overall this product is fantastic and I cant wait to hook up the other two televisions.

Quick shipping, works as intended. We used it for a 4 panel set up. Fairly easy to set up and configure,

Works as intended. Sometimes will not power off and needs to be reset. Overall this device allowed us to create a video wall with 4 50" TVs with easy set up. Would order again.

Bought two of this LINK-MI TV04 2x2 Video Wall Controller in July and September 2018 to make 4 TVs into a big video wall in two conference rooms. Works great. The resolution is 1080 HD on the resulting single display. If you have 4K TVs, it will come out as 1080, not 4K. This is still good enough for displaying pictures, video conference and online web presentation. The embedded software is easy to use to fine tune the display. One of devices became noisy with the fan. Contacted the seller and got a replacement fan. The replacement fan took care of the noise problem. Overall, quite satisfied with the devices. Recommended!

It was pretty easy to set up however it only reads a 1920x1080 max video and projects it across the four screens the quality that comes out is complete garbage. I also think mine was defective or broken because it had a purple bar across all of the screens which was super annoying. I ended up returning it. probably wouldnt buy this again.

I have two of these driving two sets of 4x46in monitors. They work great, and the customer service has been fantastic. I recently had an issue with one of the power supplies, and the seller immediately sent me a new one. I also haven't tested it over long periods, but it can actually take in a 4k signal, not just 1080p as listed.

Unit died within 2 years

This easy to install video wall controller is well priced. It takes about 5 minutes for a know nothing like me to get it up and running. There is a resolution limit thought so consider the overall size of the image because it will only feed it as one 1080 p image. I was able to feed an image over 4 -60" Samsung TVs but it was like simply enlarging the image, and the image degraded.
