By the end of 2017 Redstone Wave2 will be available making massive changes to DPI. The news is microsoft is blaming the fact they must support 4''-84'' displays and they just don't have a way to recognize monitors properly, like they have been able to do in previous windows editions...
That said f any of the text on this web page looks blurry, you have fallen victim to bad dpi.
