I have a 2018 Mac Mini driving two 4K displays with Display Port over USB-C cables. I previously was driving 2 x 24" 2K displays (same cables) and had no performance problems. Once I upgraded to the 4K displays I've observed very noticeable display draw performance issues. It's not enough for me to give up the 4K displays but I'm wondering if this is improved on the current M1 Mac mini?
