Yeah, I will try it, but in 90% the font is to small then. The next resolution steps lower to make fonts bigger are 1152 x 864 or 1024 x 768, but in this case the font with 100% is ok, but menues and icons and tables are too big...

I am surprised that a tool needs a fixed resolution proportion to show all features well (apart from games...). I think thats not very professional in 2017... EVERY other tool works with my 120% font.
edit:
btw: the font size in Visionaire depends mainly on the settings in the template css, right? You can set the font type and the pixel size. I hope for all fonts using in the gui, I'm not sure...
