Ue4 viewport blurry with windows scaling

I have recently purchased a 1440p monitor, for a dual monitor setup. Windows sets my main monitor at 125% scaling and my second monitor a 1080p at 100% scaling.
The problem is that the UE4 editors viewport is very blurry on the 1440p monitor, while very clear on the 1080p.
The issue is even more visible by increasing the scaling in the windows display options.

Seems weird this hasn’t been fixed before, doesn’t anyone at epic have a higher res monitor than 1080p?
