Scaled mode (HiDPI) does not work correctly (is blurry) on 1440p HDMI display on Mac Mini 2018 with Big Sur
I can't get scaled mode to work correctly on a 1440p HDMI display on a 2018 Mac Mini. It's blurry, like it is just scaling the resolution selected to 1440p rather than doing HiDPI. Unscaled it is working correctly and is a crisp 1440p. Neither display options in System Preferences or SwitchResX is able to make it work. 4k HiDPI is working correctly on the 4k monitor that is connected via Thunderbolt.
Mac mini 2018 or later
