[SML] LED Television Wall

If you’re into programming you can build a pi wall using raspberry pi units.    https://www.screenly.io/use-cases/applications/raspberry-pi-video-wall/   I seem to remember a poster session at USITT a few years ago where someone talked about doing this.   It involves some programming but it allows you to build a scalable system that requires a pi unit for each monitor and one master unit.  You can choose between all of the units displaying video or set it up for multiple displays.  From what I remember it was a lot of work.

When I needed multiple monitors I contacted my media department and borrowed units from them.  You might see who does media on your campus for meetings and see if they can help.

I’ve done this with 4 monitors and qlab to run a video wall effect.  Qlab let me set up a 2 by 2 layout and I could set up different surfaces so I could access all 4 screens as 1 image or each screen separately.  It did require a separate video output for each screen.   I was using triplehead2go units at the time but there are other video splitters you can get.  These units split the video output by increasing the screen resolution 2 or 3 wide and then outputting it as 2 or 3 separate outputs.  You could also add extra video cards to a computer but you’ll need processing speed to make it happen.   I’ve run 5 monitors out of a mac tower on qlab.

I’m sure there are other solutions, this is what I have done in the past.    Feel free to email me if you want to talk more about it.  It’s a lot of work but ultimately you’ll be very proud when you get it all done and it works.   Good luck

I have seen some good prices at Walmart on 50" units lately. I would also check Sam's and the other like type stores.
To hold them solid I would also get the mounting brackets.

Yes, we have checked into them. In SD they are very expensive. We are trying to see if we can source all the materials ourselves and build for cheaper.

Any suggestions on where we can find simple LED Televisions to use as a video wall in an upcoming production? The size we are looking for is 50” to 55”. We don’t need smart tv’s and are only looking for televisions with an HDMI input.

Any suggestions?
