Did anyone find an ideal screen size / resolution for Pd yet?

I can not recommend:
14 inch at 1920 x 1080 with 150 % scaling in OS
15,6 inch at 1920 x 1080 with 125% scaling in OS
Either needs zoom-in and there is not much space for patching left.

Ideally the screen would sit below ear-level for great studio acoustics. But I probably have to reject this premise.

(...while waiting for mouse-wheel zoom https://github.com/pure-data/pure-data/pull/1659 )

@lacuna Consider 16:10 ratio, getting that extra vertical space makes a big difference in pd and works fairly well with most audio software, 16:9 is not great for most computer tasks. I am perfectly happy with my 13" 1920x1200 and no scaling, but my patching style tends to be denser than most which might be part of it and my choice of a static tiling and tabbed window manager really helps with efficient screen usage.

Edit: Have you tried not using OS scaling and just configuring each application to work? Most application allow you to tweak all the interface settings/set a default zoom, I think pd is the only application I use which does not allow it, at least on linux, not sure what OS you use.
