Compared to M1? Because my Intel MBP has done that for years.

I now use an M1 mac mini with two 4k monitors (not from one cable though)

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?

I haven’t noticed any display lag on my end. But I don’t do latency sensitive things like gaming.

1 monitor (Dell P2715Q) is hooked up using DisplayPort. The other (LG 27” IPS 4K) is using HDMI 2.0. Both are running 4K retina at 60Hz without any issues.

I had so much trouble finding this out before I bought it which is why I am vocal about the fact that it works.

Thanks for the information! I am tempted to upgrade my 2018 when the next revision (M1X or M2?) Mac mini comes out to improve the display refresh rate issues.

The M1 MacBooks can only drive 1 external monitor because they're already driving the internal display.
