Screen tearing - RTX-A-4000 with MOSAIC on Linux (Ubuntu 20.04)

I have an RTX-A-4000 card with 4 x DP ports on the back and I’m trying to prevent screen tearing by using MOSAIC on the one graphics card across all 4 monitors.
I am not sure if MOSAIC is enabled correctly in the Meta Modes scripts I am being referred to. How can I be sure that Mosaic is enabled and active to prevent screen-tearing?
Thanks

Mosaic is for making use of two or more gpus, always disabled if only one is available. Also, it doesn’t have anything to do with tearing. Please try the “ForceCompositionPipeline” Xorg option.

Thank you. I understand the FCP is used to solve Screen tearing but it introduces latency. I was told by support that MOSAIC can help. I was referred to the Meta Modes options but I am not sure if they are working.

Screen tearing can only be solved by running vsync’d which will always introduce latency, it has to wait for the next vsync to display.
What kind of MetaModes are you referring to?
