I opened a small restaurant and recently wanted to buy a larger TV, but it was quite expensive. I ultimately chose this splicer, and the result was surprisingly good.Very high-definition, smooth video playback, guests can still sing after dinner, very perfect, no software required, plug and play. And the price is very nice, great buy.

The bezel adjustment does not allow viewing of the entire image. For example, when watching a football game, there is a missing portion of the image between the left and right monitors. The football and stats will momentarily disappear. I missed my return window or this would have been going back for a different unit.

We have a 24 foot wide wall and we needed to be able to fill the entire wall with a projection. We looked at native projector options, but to get the size and quality we wanted, we would be looking at a professional grade projector for tens of thousands of dollars. Instead, we found this video wall controller. Currently, we have it connected to two individual sub $1000 projectors and it works perfectly! The entire wall is filled and the quality is great. We couldn't be happier. The features of the controller also allow for lots of configuration options in the event that we'd like to change the configuration later. If you want a giant display wall, this is your answer.

I have a small restaurant, I put four TV screens in the one room, and use this machine, It perfectly expands the video. Very easy to use, you can switch modes freely. Some guests will also open a small meeting in our simple meeting. It feels very practical.

This unit doesn’t do 4x1 vertical screens as it claims.

Worked great for 1 year and 1 month then it died

We purchased this for our church. We had one very old projector and screen, but wanted to upgrade for our new facility. We bought 4 55" HD TV's and this. We run off a mini MAC. The trickiest part was building a metal rack to mount all four TV's in position, top two upside down to keep the thinnest bezels in between. This device pulled them all together and it looks awesome. We are very happy!
