It’s been a while since I have posted here. I need your collective opinions to solve a problem that I am struggling with.
I am planning to build a CRT video wall. I want to have a single video input, spread out over different TVs. I am aware of the pi-wall project as an option for this setup.
However, with the current chips shortage going on, obtaining a raspberry pi is very hard. They are mostly sold out or way overpriced.
What are alternative solutions to get the same result?
Raspberry pi is about as cheap as you can get unless you can score a cheap second hand video wall splitter or a bunch of syncable pioneer DVD players for cheaper but they would probably be the same price as a £35 Raspberry Pi.
I recently purchased an 8x8 matrix switcher (learned about them from a studio setup post from @amfas ) for just under $80 on ebay (in U.S.). Depending on how many CRTs you are using to make the wall, I have seen them up to 32x32, but of course they get more expensive the more in/out they have.
Those matrix switchers are great. I have in use as well. Unfortunately these will only duplicate your signal. I am looking for a solution to split my signal, which isn’t possible with just a analog chain.
But thank you for your responding!
Know of any resources for what software to use for a Pi-matrix? The dual HDMI outs might not actually save money if you don’t already have extra HDMI-to-composite converters lying around. Probably best to just use the Pi’s composite out.
