Good news: based on screenshots (1, 2), the Steinberg’s latest product — Dorico — supports HiDPI (High-DPI, Retina) and provides quality sharp nonblurry GUI.
The screenshots are obviously taken on macOS, but hopefully HiDPI support also applies to Windows version of Dorico. A confirmation by a Steinberg’s official (probably by Armand Rochette, Ben at Steinberg, or Daniel at Steinberg) or an actual user of Dorico for Windows would be welcome.
It’s logical to expect that the upcoming Cubase 9 will support HiDPI too.
To Steinberg developers: a solution for compatibility with VST plugins that don’t support scaling is to implement VST host as a separate executable so that Windows could apply DPI scaling to the VST host even if the DAW itself is in HiDPI mode.
For what it’s worth, among major Windows DAWs that are already HiDPI-compatible are:
- Image-Line FL Studio 12+ (scalable up to 400%, HiDPI mode is enabled by default, extra non-DPI-aware executables are provided for use with outdated plugins);
- PreSonus Studio One 3+ (HiDPI can be enabled in settings);
- Ableton Live (formally not DPI-aware and so blurry by default, but there is a setting for scaling up to 200%, and the DAW works correctly when HiDPI mode is forced via executable’s properties).
