Fonts are blurry / big in Android Studio
You need to set a compatibility option "Disable display scaling on high DPI settings" for the application.
Right-click the taskbar button, then right-click the app name, select Properties, Compatibility. Set the option, save changes, restart Studio.
Those instructions are for a Win7 machine, but Win8.1 should behave the same.
To explain what is happening: apparently, the Studio is not "high DPI aware", i.e. does not declare "I know how to handle myself on a high-DPI screen", and Windows tries to scale the window so that its elements do not get too tiny.
You can override this on an app-by-app basis, but be prepared for possible glitches / tiny UI elements.
- Right click on your android studio icon. Go to : Properties -> Compatibility.
- Check the "Override high DPI scaling behaviour" option also select "Application" for "Scaling performed by" from the drop down menu.
- Press apply and restart your android studio.
