Interestingly enough it doesn’t effect the launcher…so maybe if I take a picture of the editor in comparison to the launcher that might help?
It is also the editor as it effects ALL projects loaded into it. I have uninstalled and reinstalled the editor and that doesn’t seem to solve the issue.I don’t have another PC to test multi monitors on to try and reproduce it either. I am still hunting the issues and as I mentioned in that thread I don’t know if taking screenshots really means anything because I can’t take a screenshot of what it looked like before it started doing this for comparison. However, initially it scaled fine even in 4.13.
This is basically the same problem I am running into that I posted here Working DPI Scaling For The Editor - Feedback for Unreal Engine team - Unreal Engine Forums
