From last few days, the font has become blur on my Windows 10 machine. This issue was with the web browsers, notepad, word document etc. I tried to fix the issue by using the option "Disable Display scaling on high DPI settings" but it didn't worked. I managed to find an easy fix.
Go through the below mentioned steps:
Windows Start Menu => Settings => System => Display => Advanced Display Settings => Related Settings => ClearType Text => Turn on ClearType => Select one of the font options and complete the steps.
This helped me to fix the blur issue. Try it out!!!
