title: PyQt4 window size changes on different computers
body: <p>Problem:
  The problem is best explained by looking at the two attached pictures of the same program. The picture of the smaller window was taken on a Notebook(Win 10)</p>

  <p>while the picture of the larger window was taken on a desktop PC(Win 10)</p>

  <p>As you can see, the window enlarges on the desktop PC, which doesn't look good. It also happenes to other programs of mine: the text label sizes stay the same, the button sizes stay the same, but pictures get bigger and get blurry.</p>
  
  <p>It doesn't matter if I use a layout manager like vertical or horizontal boxes or a grid layout or if I use fixed positioning. 
  It just looks ugly.</p>
  
  <p>Question:
  I would like the window (and widgets) to keep its dimensions, as seen in the Notebook version.
  Is there any way to achieve this? There has to be right?</p>
