title: PyQt5 Resize app for different displays
body: <p>I am using PyQt5 and Python 3.6.4 to design a ui for a program. It was made on a 720p monitor however now using the same code on a 4k monitor, everything is tiny apart from the text. How would I go about resizing the whole app to look the same on all monitors: (720p, 1080p, 4k, etc.)
  The program is to be run on windows through an executable created through compiling the python code.
  Cheers</p>
