RE: Dell Inspiron 15R SE 7520, blurred display after upgrading to windows 10

Yes. It's quite easy: Right click the desktop -> Display Settings -> Scale and layout -> Change the size of text, apps, and other items -> change to 100% or 125% or something like that.

Another place to look at is control panel, resolution, "make text and other items larger or smaller" then make sure the box for "let me choose one scaling level for all my displays is checked"
