DPI Scale Blurry Text FIX Windows 10 FIX
Blurry text in Windows 10 most often occurs when using a large, high-resolution display, such as a 4K UHD monitor. This is because Windows is designed to scale text on high-resolution displays to make it easier to read. However, some people complain that this scaling technique can sometimes cause blurry text.
The best way to fix blurry text in Windows 10 is to go through possible solutions and start with the most likely problem.
Vary the DPI scale in Windows settings. If you have a high-resolution display, Windows probably automatically sets the DPI to 125% or 150%. Changing that value may fix the problem. For example, if it's 125%, increase it to 150% and see if text looks sharper.
