hidpi doesn't work (27" 2560x1440)

I have a macbook pro (2020) m1. And since it doesn't support up to two external monitors. So I use displaylink and hidpi doesn't work. How can this problem be solved?

Hi - if the displaylink driver does not provide the required HiDPI resolution then your only option is to create a virtual screen and set it to the right HiDPI resolution and mirror or stream it to your displaylink screen. The results might not be super-satisfying though.

Thanks! The stream works well, I found with this setup, I got both physical display and virtual display in the Display preferences. Is it possible to hide the physical display?
