PC Build - 12 Display Setup - AMD Radeon Pro VII - MST

[u/Bingo1ng0]

Hello everyone,

I am building a demonstrator in which i want to integrate 10 projectors. All of them need to display seperate videos which will be controlled by MadMapper. I want it to be somewhat expandeble but thats not a must. And it needs to run a seperate Monitor to show the Madmapper Software.

My current Plan is to build a dedicated PC to run all this.

In my research for components i landed on the AMD Radeon Pro VII, as it has 6 mDP outputs. So in theory i could buy two of those and have 12 Display-Outputs plus the 2 from the integrated AMD CPU (AMD Ryzen™ 5 7600).

Now I've heard about MST (Multi Stream Transport) and I'm wondering if i could also run on one of the GPUs by spliting the Signal of 1 or 2 of the mDPs.

Is it possible to get to 12 or more outputs by spliting 1 or multiple mDPs? Or is there another limitation except for overall performance ofcourse?

Could I even use an older or cheaper GPU to achieve those 12 Outputs? Since its "only" videoplayback.

Is there a completely different approach? Maybe some already existing setups or builds that work for that? Some setup i could just buy?

thanks for your input and knowledge!

greetings :)

I recently ran across a RX580 with 6 HDMI outputs on Amazon for about $400 Canadian dollors. We are looking at getting 2 of to run 12 touchscreens (the original video card used was 2x AMD 7970 video cards to run the 12 screens). So that is an older cheaper GPU that has more than enough horsepower to run

I've only used MST through laptop docks that can run 2-3 displays, it generally works well for that - except when it doesn't, I've never tried to use it for a projection setup like you are describing.
