For exaple 2x2 video-wall it is much easier to feed with 1x DP 1.2 daisy-chain with UHDp60 if supported by monitorn like NEC X555UNS.
But then you need 2x2 cameras/outputs split of one UHD signal to do bezel correction wich is currently not supported.
If we would be able to do manual splits, or split splits (sounds crazy I know) it would be a really good enhancement!
