Thanks AirVince for your reply…
You should have a look at the 150% scaling. I have my screen currently at this scaling. (4K on 17 inch laptop).
It seems the scaling of the engine prime software at 150% is identical to the one at 175%, 200% and 225%.
Changing it to 250% makes it bigger. Changing it to 125% makes it smaller.
For me 150% would is ideal as this results in readable characters in all software, but this setting results in characters that are way to large in the Engine Prime. (see attached screenshot)
Hopes this makes sense?
