A while ago I asked if there was a way to change the display scaling on launching Aurora in Win10, which I never did get to work ...
http://aurora2.pentarch.org/index.php?topic=11545.msg158576#msg158576... but I just found a one click method using a third party SetDPI.exe from imniko on github (which virus-scans as safe at virus total and Jotti's malware scanner).
https://github.com/imniko/SetDPI/releases/Very simply, a batch file for each resolution = push button DPI changer
e.g. first number is display # , second number is display scaling.
SetDPI.exe 1 100
SetDPI.exe 1 125
Two batch files in same folder as SetDPI.exe each with one of the above code snippets, shortcut to each .bat with suitable icon placed in a play folder which also has my Aurora shortcut in and I have a little control panel to let me play Aurora in a couple of clicks. Happy days!
Just thought I would share FYI. Its a bit easier than changing display scaling every time but not much...
