I’ve tried a lot of DAWs lately to see how they handle HiDPI on Windows in comparison.
Bitwig seems to be the best at this. Bitwig>Ableton>FL Studio>Steinberg Cubase/Nuendo. All the DAWs but Steinberg are usable with old plugins and Bitwig/FL Studio have options for scaling.
So please Steinberg look at how Bitwig implemented their scaling/mutli monitor support on Windows as the benchmark. Ableton is a close second but does not offer any options, it just handles it properly most of the time.
Also I noticed strange behavior in Steinberg DAWs if you open the plugin on a different monitor and drag it, sometimes better sometimes worse. It is really frustrating. If I open NI on the 4k montior and drag it to the 1080p it looks fine. But if I open it on the 1080p and drag it to the 4K it is cut off!
My screens are unusable w non-scalable plugins until this is fixed. I am using a 27" 4k, 24" touchscreen 1080p and 55" OLED 4K and trying Cubase vs Nuendo for game music composition. If this isn’t fixed soon I am going to have to downgrade to all 1080p monitors, but then I cannot work on 4K videos and game materials! This is 2020, we are going to 8k soon!
Just a few brands of plugins that do not work in Steinberg:
to name a few that I’ve tested, and some of the ones that do scale correctly have issues with the menus showing up on wrong monitor if you move it from one monitor to another
Some brands that DO work:
