I’m loving the HiDPI mode on my 3440x1440 screen.
I can now see everything clearly at a distance without having to squint at the screen. Much more relaxing.
Unfortunately it makes most third-party plugins much smaller and therefore harder to see, but I guess that is the fault of the plugins not Nuendo.
The latest Steinberg and Fabfilter plugins work well, but UAD, Eventide and others don’t have scalable UI’s at the moment.
