Disable display scaling on high DPI settings system wide?  

I have recently started using a Lenovo Yoga 460 for work and the display running at 1920*1080 is completely unusable (far too small for the kind of stuff I need to display on screren). I therefore run at 125-150 % magnification which for the most part works fine - things like Windows Explorer and the majority of dialogue boxes are totally clear.

However, there are many areas that are not so clear. One workaround I have found is to disable DPI scaling in the compatability options of the app. I am having to do this on a per app basis though and it doesn't help in some areas of the O/S.

So, I am looking for a way to 'disable display scaling on high DPI settings' but system wide.

Any help appreciated, thanks.

You can try: Windows 10 DPI blurry / fuzzy text font fix - XP Explorer. It makes Win 10 use DPI scaling method from Win 8. You can set DPI % with much better and uniform results.
