Computers using HiDPI windows scalling with non hidpi apps will blur the interface (it will scale the interface like a bitmap, not like a vector).

To add HiDPI Support, just add this to manifest file.
VS2015 already have it, just need to uncomment the section.

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" > <asmv3:application> <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings"> <dpiAware>true</dpiAware> </asmv3:windowsSettings> </asmv3:application> </assembly>
