Is there a option in the settings or parameter in the beta? I have installed the 2018.2 beta and didn’t found anything…
I’m also in 2018.2 and I have a 27" 4K monitor and although it seems to attempt something in the beginning (the screens get’s all gray) it then get’s back to the normal Dpi with tinny text. I’m waiting for the next version to see if it fixes the problem.
Is there a fix yet? It’s 2021 now
The solution at this point is to use fractional scaling on your display. It works pretty well for the most part, though for Ubuntu it is still considered experimental. Windows is the only editor version that allows you to set your DPI scaling independent of the system setting at this point. I know the experience on a 4k display at 100% scaling is suboptimal. Feel free to log a bug as well.
I have my scaling set to 125% on KDE plasma (which is the optimal size for me), unity still does not scale at all. I am using the latest version of Unity 2021 LTS and KDE plasma 5.24.6 on X11.
