Screenshot of workaround
There is a workaround that makes the UI less blurry (but still a bit blurry):
- open the Properties dialog of eclipse.exe
- go to tab Compatibility
- click the button "Change high DPI settings"
- in the new dialog select at the bottom the option "Override high DPI scaling behavior."
- for the "Scaling performed by:" select "System (Enhanced)"
The start eclipse.exe, now it is less blurry, see screenshot.

FWIW, this is a known issue. SWT doesn't support per-monitor DPI (yet), at least not on Windows. This means that SWT uses primary monitor DPI for everything and the system autoscales SWT windows on secondary monitors, resulting in magnification blur. Unfortunately, fixing this is rather involved. Alternative partial workaround is to use the highest DPI monitor as the primary monitor. Created attachment 281395 [details]
Screenshot of workaround #2
Setting the monitor 2 as main display makes Eclipse look much better (when on monitor 2, on other it is again blurry). This is with reverting the eclipse.exe properties settings to default.

Created attachment 281382 [details] screenshot of problem, on monitor #2 I have Window 10 , version 1909. Eclipse IDE for Enterprise Java Developers. Version: 2019-09 R (4.13.0) Build id: 20190917-1200 My monitors are: 1: 1920x1080 , scaling: 150% 2: 2560x1440 , scaling: 125% 3: 1920x1200 , scaling: 100% (this one is marked as "main display") When I put Eclipse on the biggest monitor (#2), then almost everything in it is blurry. See screenshot. It is similar on monitor #1. On the monitor #3 it seems OK. Keywords: DPI,scaling,blurry,text
