Multiple monitors (TV) setup - Video Wall

I have build a TV (monitor) wall where I like to share videos, but, also I would like to share presentations, desktop screen etc. All the TVs are frame-less with 4K resolution, but with different size & rotation (you can see the photo). Now, I'm trying to figure it out what is the optimal hardware / software that can be used and purchased in order to achieve this.

Anyone can help?

None of those is helping. I already have the hardware. I can use the https://piwall.co.uk/ however, with it I can only present videos, not desktop or presentations

 

You cannot render a functional desktop over monitor wall with arbitrary shape. Well you could do it, but you have to record it before as a video and than play it later or do it as a continuous real-time stream. But even if it would work, presenting something or sharing desktop program over your irregular configuration would surely be a nightmare for any audience to watch. There are also block-based displays which could be connected to each other and do what you want but their image quality is a potato compared to a TV.
