I now the subject has been discussed, but I haven’t found any recent posts (the latest is more than six months old). So: does Renoise work well in a 4k monitor? Is it usable?
It is not optimized for 4k, however it is on the feature list for next release. Unfortunately next release may still be awhile off, but the developers are aware.
I’m running 4k in Windows 10 with 200% scaling. No problems whatsoever and looks about the same as 1920x1080 with 100% scaling.
However, something like 150% scaling looks rather ugly - at least in Windows.
I never found a software that can set scaling level per application, so unfortunately I have to use 200% globally for Renoise to look good.
