Cannot find experimental modes in my Mac OS display settings after enabling HiDPI

macuser012 · 03-08-2026, 04:31 PM

I am trying to enable experimental mode on my M1 Mac Pro so that I can use HiDPI modes on my 34 inch monitor that supports 3440 x 1440 res. However, after following instructions from the official docs here: https://support.displaylink.com/know...ticles/1993915)

I am not able to see the additional modes in my Mac display settings.

Would appreciate some help on this, thanks.
