No I'm asking if you can Give a part of a screen to each gpu so that 4 pairs can add their 4k screens to make a 8k output through something
You're basically asking about doing this, just with "only" 8k. They used Quadro sync to give each display it's own portion of a screen, which requires Quadro GPUs.
Additionally, you cannot split the output from one card (or pair of cards) to multiple monitors and show different content.
