4K screen scaling issues on Win 10

Some people with 4K laptop screens have had issues with SAB.

One option is to set the scaling on that Window to 200-300%, but if that does not work for all text then the following should work.

You need to adjust a compatibility settings on javaw.exe.

Where is javaw.exe stored? You can search for all occurance and do the same to all the ones you find or you could open a command prompt and enter:

reg query "HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\1.8" /v JavaHome

it should return something like:

    JavaHome    REG_SZ    C:\Program Files\Amazon Corretto\jre8

So the path you want is that path with a \bin on the end:

C:\Program Files\Amazon Corretto\jre8\bin\javaw.exe
  • Right click on the javaw.exe file in Windows Explorer.
  • Select Properties
  • Choose the Compatibility tab.
  • Click the Change the high DPI settings
  • In the section High DPI scaling override section check the Override high DPI scaling behavior
  • Set Scaling performed by: Application
  • Click on OK.
  • Click Apply
